Climate change has been on the world’s radar for decades. Predictions made by scientists at oil giant Exxon in the early 1980s are proving accurate. The damage done by a hotter, more chaotic world is worsening and getting more expensive.

Even so, many countries around the world are failing to meet their emissions targets, with major gaps found even this week between the commitments and actions needed to hold global warming to 1.5°C.

This has put Earth on a dangerous path, as our new report on the state of the climate reveals.

Earth’s vital signs ailing

Last year was the hottest on record. It was also likely the hottest in at least 125,000 years.

Every year, we track 34 of the planet’s vital signs. In 2024, 22 of these indicators were at record levels. Carbon dioxide levels in the atmosphere and ocean heat both hit new highs, as did losses of trees to fire. Meat consumption kept rising and fossil fuels consumption reached new heights.

The consequences of climate inaction are ever more clear. In 2024, the world’s coral reefs suffered the most widespread bleaching ever recorded, affecting roughly 84% of the world’s coral reef area between January 2023 and May 2025.

Greenland and Antarctic ice mass fell to record lows. Deadly and costly disasters surged, including the flooding in Texas which killed at least 135 people while the Los Angeles wildfires have cost more than A$380 billion. Since 2000, global climate-linked disasters have now caused more than $27 trillion in damages.

Stories and statistics like this are sadly not new. Many other reports and warnings have been published before we started this annual snapshot in 2020. Therefore, our report this year focuses on three high-impact types of climate action, across energy, nature and food.

Energy

Combined solar and wind consumption set a new record in 2024 but is still 31 times lower than fossil fuel (oil, coal, gas) energy consumption. This is despite the fact renewables are now the cheapest choice for new energy almost everywhere. One reason for this are the ongoing subsidies for fossil fuels.

By 2050, solar and wind energy could supply nearly 70% of global electricity. But this transition requires restricting the influence of the fossil fuel industry and a full phase out of fossil fuel production and use, not the expansion we continue to see globally.

As a result of surging fossil fuel consumption, energy-related emissions rose 1.3% in 2024 and reached an all-time high of 40.8 gigatons (Gt) of carbon dioxide equivalent. In 2024, the greatest fossil fuel greenhouse gas emitters were China (30.7% of total), the United States (12.5%), India (8.0%), the European Union (6.1%), and Russia (5.5%). Together, they accounted for 62.8% of global emissions.

Sadly, much of the rise in fossil fuel electricity generation may be due to hotter temperatures and heat waves.

Although there are concerns over the environmental impacts of renewables, the greater threat to our biodiversity is climate change and biodiversity conservation and mitigation measures can be part of project planning.

Nature

Protecting and restoring ecosystems on land and in the ocean remains one of the most powerful ways to support climate change, and support biodiversity and human well-being.

Protecting and restoring ecosystems such as forests, wetlands, mangroves and peatlands could remove or avoid around 10 Gt of carbon dioxide emissions per year by 2050, which is equivalent to roughly 25% of current annual emissions.

But we must also stop destroying what we have. Global tree cover loss was almost 30 million hectares in 2024, the second highest area on record and a 4.7% increase over 2023. Tropical primary forest losses were particularly large in 2024, with fire-related losses reaching a record high of 3.2 million hectares, up from just 690 thousand hectares in 2023, a 370% increase.

Food

Approximately 30% of food is lost or wasted globally. Reducing food waste could greatly reduce greenhouse gas emissions since it accounts for roughly 8–10% of global emissions. Policies supporting plant-rich diets could also help slow climate change, while offering many benefits related to human health, food security, and biodiversity.

The technical mitigation potential associated with switching away from eating meat may be in the order of 0.7–8.0 gigatonnes of carbon dioxide equivalent per year by 2050. This is in part because methane emissions from cows, sheep and other ruminant livestock account for roughly half of all agricultural greenhouse gas emissions. Per capita meat consumption hit all-time highs in 2024, and we currently add 500,000 more ruminants per week.

Creating global change

In our report, we note that social tipping points can trigger climate action. These refer to moments when a small, committed minority triggers a rapid and large-scale shift in social norms, beliefs, or behaviours. Research shows sustained, nonviolent movements and protests involving just a small proportion of a population (about 3.5%) can help trigger transformative change.

Many people underestimate just how much support there is globally for climate action, with most people believing they are in a minority. This arguably fosters disengagement and isolation. But it also suggests that as awareness grows and people see their values reflected in others, the conditions for social tipping points may be strengthened.

Reaching this positive tipping point will require more than facts and policy. It will take connection, courage, and collective resolve. Climate mitigation strategies are available, cost effective and urgently needed, and we can still limit warming if we act boldly and quickly, but the window is closing.

How a ‘sewer socialism’ revival could see Zohran Mamdani become New York’s next mayor

Democratic candidate for mayor of New York City Zohran Mamdani looks increasingly like the one to beat at next week’s election. But he is up against more than the usual political challenges.

US President Donald Trump has referred to him as “my little communist” and called his nomination “a rebellion”. More recently there have been calls for Mamdani’s citizenship to be investigated.

Born in Uganda, and the first Muslim nominee for mayor of the biggest city in the US, the 34-year-old Mamdani is an obvious target. But it is his stance as a democratic socialist that has really invited the old-school “red-baiting”, aimed at discrediting him by invoking Cold War anxieties.

In fact, Mamdani’s approach to democratic socialism is less about an abstract political ideology than it is about practical solutions. As he has put it:

We want to showcase our ideals, not by lecturing people about how correct we are, but rather by delivering and letting that delivery be the argument itself.

Because of this, he has also been described as an heir to the historical tradition of “sewer socialism”, a brand of left-wing thinking that favoured incremental, practical reform over revolutionary rhetoric.

Delivering tangible results

Despite the long history of anticommunism in the United States, Milwaukee in Wisconsin was the nation’s socialist capital for decades.

A succession of socialist mayors focused on delivering basic services to the people of the city. Socialist candidates dominated city politics there for 50 years, from 1910 to 1960. It was the most successful political achievement for socialism in US history, largely because it appealed to the mainly German immigrant population.

The term “sewer socialist” was actually first used derisively by Morris Hillquit, national chairman of the Socialist Party, who ran unsuccessfully for mayor of New York several times.

At the 1932 party convention in Milwaukee, Hillquit was almost replaced as leader by local mayor Daniel Hoan. Mayor from 1916 to 1940, Hoan was justifiably proud of the city-owned sewer system. But he also established one of the first public bus systems in America, and built the country’s first public housing project.

This repeated success in city politics – despite the national opposition to socialism and Hillquitt’s “sewer socialist” slight – was built on delivering tangible results to the voters.

And it’s that approach that is seeing sewer socialism making a comeback in city politics today, as urban dwellers face an affordability crisis and declining quality of life.

Mamdani is not the only millennial socialist candidate running for mayor.

In Seattle, over on the US west coast, 43-year-old Katie Wilson is a strong contender in a tight race with the incumbent mayor, 67-year-old Bruce Harell. Wilson is the founder of the local Transit Riders Union and has expanded her progressive activism to social housing, public safety and homelessness.

She doesn’t see the socialist label as a major issue on the campaign:

I’m a socialist. I’m fine being called a democratic socialist […] We’re in a moment where most people don’t care that much. People are not that hung up on labels and want to see results on issues that affect their daily lives.

Beautiful, contradictory, unfinished

Like Wilson, Mamdani lacks the experience of his opponent, former New York governor Andrew Cuomo (67).

Cuomo played on this in the final debate of the campaign, telling the young challenger, “the issue is your lack of experience”.

Mamdani replied that his opponents “speak only in the past because that is all they know”.

Perhaps inevitably, some are saying Mamdani’s ability to connect with voters not only promises to deliver an improved quality of city life, but may also make him a viable presidential candidate who could “save” the Democratic Party in 2028.

Speaking on the 4th of July, Mamdani said: “America is beautiful, contradictory, unfinished, I am proud of our country even as we constantly strive to make it better.”

Vice President JD Vance responded the next day: “There is no gratitude here […] We should demand that our people, whether first or tenth generation Americans, have gratitude for this country.”

Intended as an insult, Vance also accurately described Mamdani’s surprise win in the primary: “Last week, a 33-year-old communist running an insurgent campaign beat a multi-million-dollar establishment machine…”.

But it might have been Fiorello La Guardia, mayor of New York during the Depression, who best described how such a turnaround could have happened: “There is no Republican or Democratic way to pick up the garbage.”

In other words, basic municipal services don’t depend on party politics. And if neither major party cares enough about those essential quality of life issues to actually deliver, maybe a younger “sewer socialist” will be the one to pick up the trash.

Nuclear-powered missiles: An aerospace engineer explains how they work – and what Russia’s claimed test means for global strategic stability

Russian President Vladimir Putin, dressed in a military uniform, announced on Oct. 26, 2025, that Russia had successfully tested a nuclear-powered missile. If true, such a weapon could provide Russia with a unique military capability that also has broader political implications.

The missile, called Burevestnik, was reportedly successfully tested over the Arctic Ocean after years of development and several earlier initial test flights, one of which resulted in the deaths of five nuclear scientists.

I am an engineer who studies defense systems. Here is how these weapons function, the advantages they present over conventional missile systems, and their potential to disrupt global strategic stability.

Conventionally powered missiles

Missiles have been used by militaries around the world for centuries and come in a broad array of designs that are characterized by their mission, range and velocity. They are used to damage and destroy a wide variety of targets, including ground installations such as bases, command centers and deeply buried infrastructure; ships; aircraft; and potentially spacecraft. These weapons are operated from the ground by the army, from the sea by navy ships, and from the air by fighters and bombers.

Missiles can be tactical, with relatively short ranges of less than 500 miles, or strategic, with long ranges of thousands of miles. Missiles fall into three general categories: ballistic, cruise and hypersonic.

Ballistic missiles are launched on rockets. After the rocket burns out, the missile flies along a predictable arc that takes it out of the atmosphere into space and then back into the atmosphere toward its target.

Cruise missiles have an additional engine that is ignited after the rocket burns out, allowing the missile to fly programmed routes, typically at low altitudes. These engines are powered by a mixture of chemicals or a solid fuel.

Hypersonic missiles fly faster than the speed of sound, but not as fast as intercontinental ballistic missiles, or ICBMs. They are launched on smaller rockets that keep them within the upper reaches of the atmosphere. A hypersonic glide vehicle is boosted to high altitude and then glides to its target, maneuvering along the way. A hypersonic cruise missile is boosted to hypersonic speed and then uses an air-breathing engine called a scramjet to sustain that speed.

How nuclear-powered missiles work

Nuclear-powered missiles are a type of cruise missile. The designs are typically a form of scramjet. A thermal nuclear system uses fission of nuclear fuel to add energy to an airstream that is then accelerated through a nozzle to generate thrust. In this way, fission of nuclear material replaces chemical combustion of traditional cruise missile engines.

The concept for a nuclear-powered scramjet is simple, even if building one is extremely challenging.
Lawrence Berkeley National Laboratory

The energy density – the amount of energy released per unit mass of fuel – available from nuclear fission is millions of times larger than that released by chemical propellants. This feature means that a relatively small amount of fissionable propellant can be used to power a missile for much longer periods of time than chemical propellants can.

The United States explored developing a nuclear-powered missile in the 1960s. The effort, Project Pluto, was abandoned due to the rapid progress made at the same time on ICBMs, as well as concerns over environmental contamination associated with nuclear systems.

Advantages of nuclear-powered flight

The key advantage of nuclear-powered missiles is the extra energy, which allows them to fly farther, longer, faster and lower in the atmosphere, while executing a wide array of maneuvers. For these reasons, they pose a significant challenge to the best missile defense systems.

The Russian military claims that the Burevestnik missile flew 8,700 miles at low altitude over a 15-hour period. For comparison, an airline flight from San Francisco to Boston covers 2,700 miles in six hours. While the Burevestnik vehicle is not flying particularly fast for a missile, it is likely maneuverable, which makes it difficult to defend against.

Challenges to using nuclear power

The huge amount of energy released by fission has been the key technical challenge for developing these missiles. The high levels of energy require materials that can withstand temperatures up to several thousand degrees Fahrenheit to prevent the missile from destroying itself.

In terms of safety, nuclear technology has found very limited application in space due to concerns over radiation contamination if something goes wrong, such as a failed launch. The same concerns apply to a nuclear-powered munition.

In addition, such systems may need to remain safe in storage for many years prior to use. An attack by an enemy on a weapons storage facility that contains nuclear-powered weapons could lead to a massive radiation leak.

Early development of a nuclear-powered missile by the United States in the 1950s and ’60s ended after it became clear the idea was strategically and environmentally challenging.

Russia’s Burevestnik and global stability

The new Russian Burevestnik missile has been under development for over 20 years. While few technical details are known, Russian officials claim that it can maneuver to bypass antimissile and air defense systems.

Nuclear weapons were the basis for mutual deterrence between the Soviet Union and the United States during the Cold War. Both parties understood that a first strike by one side would be matched by an equally destructive counterstrike by the other. The fear of total annihilation maintained a peaceful balance.

Several developments threaten the current balance of power: better missile defense systems such as the U.S.’s planned Golden Dome and advances in highly maneuverable missiles. Missile defense systems have the potential to block a nuclear strike, and low-altitude maneuverable missiles have the potential to arrive without warning.

So, while much of the reaction to Russia’s announcement of its new nuclear-powered missile has focused on the challenges of defending against it, the more important concern may be its potential to completely disrupt global strategic stability.

Fed lowers interest rates as it struggles to assess state of US economy without key government data

When it comes to setting monetary policy for the world’s largest economy, what data drives decision-making?

In ordinary times, Federal Reserve Chair Jerome Powell and voting members of the Federal Open Market Committee, which usually meets eight times a year, have a wealth of information at their disposal, including key statistics such as monthly employment and extensive inflation data.

But with the federal shutdown that began Oct. 1, 2025, grinding on, government offices that publish such information are shuttered and data has been curtailed. As a result, Powell and his Fed colleagues might have considered the price of gas or changes in the cost of coffee to arrive at their decision to cut interest rates a quarter point at their latest monetary policy meeting, which ended Oct. 29, 2025.

The Federal Reserve’s mandate is to implement monetary policy that stabilizes prices and promotes full employment, but there is a delicate balance to strike. Not only do Powell and the Fed have to weigh domestic inflation, jobs and spending, but they must also respond to changes in President Donald Trump’s global tariff policy.

As an economist and finance professor at the University of Notre Dame, I know the Fed has a tough job of guiding the economy under even the most ideal circumstances. Now, imagine creating policy partially blindfolded, without access to key economic data.

But, fortunately, the Fed’s not flying blind – it still has a wide range of private, internal and public data to help it read the pulse of the U.S. economy.

Key data is MIA

The Fed is data-dependent, as Powell likes to remind markets. But the cancellation of reports on employment, job openings and turnover, retail sales and gross domestic product, along with a delay in the September consumer price information, will force the central bank to lean harder on private data to nail down the appropriate path for monetary policy.

Torsten Slok, chief economist for the Apollo asset management firm, recently released his set of “alternative data,” capturing information from a wide range of sources. This includes ISM PMI reports, which measure economic activity in the manufacturing and services sectors, and Bloomberg’s robust data on consumer spending habits.

“Generally, the private data, the alternative data that we look at is better used as a supplement for the underlying governmental data, which is the gold standard,” Powell said in mid-October. “It won’t be as effective as the main course as it would have been as a supplement.”

But at this crucial juncture, the Fed has also abruptly lost one important source of private data. Payroll processor ADP had previously shared private sector payroll information with the central bank, which considered it alongside government employment figures. Now, ADP has suspended the relationship, and Powell has reportedly asked the company to quickly reverse its decision.

Internal research

Fortunately for the Fed, it has its own sources for reliable information.

Even when government agencies are working and producing economic reports, the Federal Reserve utilizes internal research and its nationwide network of contacts to supplement data from the U.S. Census Bureau, the Bureau of Labor Statistics and the Bureau of Economic Analysis.

Since the Fed is self-funded, the government shutdown didn’t stop it from publishing its Beige Book, which comes out eight times a year and provides insight into how various aspects of the economy are performing.

Its Oct. 15 report found that consumer spending had inched down, with lower- and middle-income households facing “rising prices and elevated economic uncertainty.” Manufacturing was also hit by challenges linked to higher tariffs.

Leading indicators

And though no data is being released on the unemployment rate, historical data shows that consumer sentiment can act as a leading indicator for joblessness in the U.S.

According to the most recent consumer confidence reports, Americans are significantly more worried about their jobs over the next six months, as compared to this time last year, and expect fewer employment opportunities during that period. This suggests the Fed will likely see an uptick in the unemployment rate, once the data resumes publishing.

And if you did notice an increase in the price of your morning coffee, you’re not mistaken – both private and market-based data suggest inflation is a pressing concern, with expectations that price increases will remain at about the 2% target set by the Fed.

It’s clear that there is no risk-free path for policy, and a wrong move by the Fed could stoke inflation or even send the U.S. economy spiraling into a recession.

Uncertain path ahead

At the Fed’s September monetary policy meeting, members voted to cut benchmark interest rates by 25 basis points, while one member advocated for a 50-point cut.

It was the first interest rate cut since December – one that Trump had been loudly demanding to help spur the U.S. economy and lower the cost of government debt. Following the Oct. 29 interest rate cut, markets expect the FOMC to reduce rates by another quarter of a percentage point in December. That would lower rates to a range of 3.5%-3.75%, from 3.75%-4% currently, giving the labor market a much-needed boost.

After that, the near-certainty ends, as it’s anyone’s guess where interest rates will go from there. At quarterly meetings, members of the Federal Open Market Committee give projections of where they think the Fed’s benchmark interest rate will go over the next three years and beyond to provide forward guidance to financial markets and other observers.

The median projection from the September meeting suggests the benchmark rate will end 2026 a little lower than where it began, at 3.4%, and decline to 3.1% by the end of 2027. With inflation accelerating, Fed officials will continue to weigh the weakening labor market against the threat of inflation from tariffs, immigration reform and their own lower interest rates – not to mention the ongoing impact of the government shutdown.

Unfortunately, I believe these risks will be difficult to mitigate with just Fed intervention, even with perfect foresight into the economy, and will need help from government immigration, tax and spending policy to put the economy on the right path.

Should young people take creatine?

Creatine is one of the most widely used sports supplements across the world. It’s taken by many in the hopes of boosting strength, enhancing athletic performance and promoting muscle growth.

But it isn’t only adults who are using this supplement. A growing number of teenagers and young adults report taking creatine in the hopes of reaping the supplement’s benefits.

Surveys show that as many as 72% of male athletes aged 17-18 report using creatine. Use is typically more common among athletes, especially young men.

While creatine is generally considered to be safe for young people to use, it’s no shortcut to getting fit. It’s better for young people looking to get strong or improve their athletic performance to focus on the fundamentals: exercising, eating properly and prioritising sleep.

Creatine supplements: what the research says about how they can help you get in shape


Creatine is a natural compound stored within muscle. Although a small amount is produced in the kidneys and liver, most (around 95%) is obtained from eating meat and seafood. Creatine plays an important role in providing energy during high-intensity activities, such as sprinting and lifting weights.

Although several forms of creatine are commercially available, creatine monohydrate is the most stable and extensively studied form.

Numerous studies show that creatine supplementation enhances performance in high-intensity exercises requiring strength and power, such as strength training and sprinting. Creatine supplementation may also lead to more muscle growth when combined with resistance training, and faster recovery from exercise.

Emerging research also suggests that creatine’s benefits extend beyond the gym. Studies indicate that creatine may improve aspects of cognitive function – specifically memory and attention.

Creatine also shows promise for older adults in preventing muscle loss and protecting against neurological disorders such as Parkinson’s and Alzheimer’s.

Creatine’s safety

A typical diet that includes meat and seafood provides around 1–2 grams of creatine per day, which keeps the muscles around 60–80% full of creatine.

Taking a daily creatine supplement eventually fills the muscles with creatine. There are two common ways to do this.

The quickest and most commonly studied method involves a one week loading phase. This entails taking 0.3 grams of creatine per kilogram of body weight four times a day. For example, a 75kg person would take a total of 24g of creatine per day.

An alternative approach, which increases muscle creatine levels more gradually, is to take 3g of creatine per day for around 28 days.

Both approaches will fill muscle creatine stores. The first (loading) approach tops up creatine stores faster, which means you’ll see benefits to exercise performance faster. However, the second approach is less likely to cause temporary gastrointestinal discomfort (such as bloating and diarrhoea) which are more common when using the loading approach.

Regardless of what approach you use, taking 3-5g of creatine daily is necessary to maintain muscle creatine levels.

Numerous studies show that short and long-term creatine supplementation (up to 30g a day for five years) is safe and has no ill effects on health when taken at the recommended dosages.

The most common side-effect of creatine is weight gain as the supplement increases water retention in muscles. This extra water remains only as long as you’re taking creatine.

Creatine and young people

Although creatine is shown to be safe and effective for adults, only a few studies have investigated the effects among children and adolescents.

The available studies show that creatine appears to be safe for young people to use and can provide performance benefits, particularly for athletes. Most studies have only looked at the safety of a creatine dosage between 0.1g and 0.3g per kg of body mass per day. As such, it’s important that any young people who choose to use creatine do not exceed this dosage.

Although creatine appears to be safe for children and adolescents to take, it is possible that, without proper nutrition education and supervision of dosing, they could be at risk of misusing creatine – potentially leading to adverse effects such as stomach cramps.

A study that evaluated young athletes’ understanding of how sports supplements should be used reported that only 11% of the athletes answered questions correctly about creatine use.

Regardless of age, it’s important to recognise that supplements such as creatine are not a shortcut to improving fitness, building muscle or losing body fat. Supplements provide much smaller performance gains compared to what can be achieved through good training and nutrition alone. While sports supplements support training and recovery, significant progress comes from consistent exercise, a balanced diet and adequate sleep.

With a well-designed training programme and healthy eating plan, young people will experience rapid improvements in strength, power and endurance without the need for supplements. Focusing too soon on taking supplements could distract young people from building good training habits and healthy eating patterns.

This is why most sport nutritionists recommend using a food-first approach, which focuses on maximising diet quality before recommending supplements such as creatine.

Prince Andrew’s ‘one peppercorn’ lease exposes how little is known about royal finances

Source: The Conversation – UK – By Robert Hazell, Professor of British Politics and Government & Founder of the Constitution Unit, UCL

In announcing that Prince Andrew would no longer use his title or honours, Buckingham Palace hoped to shift the spotlight away from his friendship with Jeffrey Epstein, and the accusations of sexual abuse he has faced (and denied).

The media were encouraged to focus instead on King Charles’s visit to the Vatican, and the royal family’s good works. But this strategy has failed. Revelations about Prince Andrew’s living arrangements and finances have whetted the appetite for more.

One such revelation is his royal residence. Andrew has a 75-year lease from the crown estate on Royal Lodge, a large house in Windsor Great Park. The Times published the lease, revealing that he paid £1 million for it plus a minimum of £7.5 million in refurbishments. In return for this very large upfront cost, Andrew pays an annual rent of “one peppercorn (if demanded)”.

The crown estate is a statutory corporation operating under the Crown Estate Act 1961 (as amended in 2025), which manages a huge property portfolio including Regent Street in London and most of the foreshore around the coast, generating a big income from wind farms.

Its net revenue profit – which in 2023-24 amounted to £1.1 billion – is paid to the Treasury. The government uses 12% of the profits to fund the sovereign grant, which provides financial support for the monarchy.

Why Prince Andrew is still a prince – and how his remaining titles could be removed


Since 2019, when he ceased to be a working royal, Prince Andrew no longer receives any public funding from the sovereign grant. Mysteries about his sources of income may be hard for the palace to dispel without being more transparent about the royal finances more generally.

One particular area of interest is the Duchy of Lancaster, which last year provided King Charles with £27 million of his income. The palace website states that this is “a portfolio of land, property and assets held in trust for the sovereign. Its main purpose is to provide an independent source of income, and is used mainly to pay for official expenditure not met by the Sovereign Grant (primarily to meet expenses incurred by other members of the Royal Family).”

Prior to the sovereign grant, the monarchy was funded through the civil list. This was an annual sum of money voted by parliament, which included the annuities received by other members of the royal family.

Since the Sovereign Grant Act 2011, those annuities are no longer published. The Duchy of Lancaster’s annual report and accounts gives lots of detail about the Duchy’s income, but none about its expenditure.

The Liberal Democrat leader Sir Ed Davey MP has called for a select committee inquiry to “properly scrutinise” the crown estate, and Baroness (Margaret) Hodge, former chair of the public accounts committee, has called for greater transparency about the royal finances.

What next for Andrew?

The nine commissioners who manage the crown estate’s holdings are property experts who operate independently of government and the crown. They cannot simply terminate Prince Andrew’s lease, but there is mounting pressure on him to relinquish the lease voluntarily.

When it comes to his remaining titles, both the palace and UK government will be desperate to close the story down and move on. The government took the line that it was all a matter for the king and the palace.

Sir Alan Campbell, leader of the House of Commons, said: “The question of [Andrew’s] titles is primarily a question for His Majesty. I know there has been speculation about legislation, but the palace has been clear it recognises that there are other matters this House needs to be getting on with, and we are guided in this by the palace.”

In practice, the palace will also be guided by the government, which will be keen to avoid legislation if at all possible. Short of legislation, there is little more the palace can do.

The king could issue letters patent declaring that Prince Andrew is no longer His Royal Highness. He could also give an undertaking that Andrew would never be called upon to serve as a counsellor of state, deputising for the monarch in his absence.

If public anger remained unabated, and legislation was deemed unavoidable, a short bill could be prepared to strip Andrew of his peerage titles and remove him as a counsellor of state. It could be passed relatively quickly: the Counsellors of State Act 2022, which added Princess Anne and Prince Edward to the list of potential counsellors of state, went through all its Commons stages in a single day.

The finances are trickier. The Commons public accounts committee may hold a single evidence session just on Andrew’s finances, or launch a wider inquiry.

It may be hard to avoid the latter. Having made public the lease on Royal Lodge, the crown estate may find it difficult to refuse to disclose the leases on other properties occupied by the royal family, or other information about its finances.

If parliament decides to launch a wider inquiry, the payments to other members of the royal family funded by the Duchy of Lancaster would be an obvious place to start.

Why so many children in the youth justice system have special educational needs

Walk into any custodial youth justice facility in the UK – from young offender’s institutions to secure training centres and children’s homes – and you’ll be met with an unexpected reality: the majority of children in these settings have special educational needs and disabilities.

In particular, a very high proportion of children in custody have neurodisabilities. These are long-term conditions affecting the brain and nervous system, and range from autism to brain injuries and foetal alcohol spectrum disorders.

These conditions are grouped together because they affect children’s cognition (including memory, attention and concentration, and executive functioning – mental skills necessary for daily life), as well as their emotional regulation, social communication skills and physical development. This is a pattern repeated in youth justice systems across the world.

For example, estimates suggest that 50% to 87% of children in custody globally have a brain injury. However, research from Canada suggests that brain injury affects around 20% of children in the general population. Over 60% of children in custody globally have a speech, language and communication impairment, compared with 1-3% in the general population globally.

Autistic children make up between 2% and 18% of children in custody across Europe and the USA, compared with 0.3 to 1.9% in the general population in Europe and the USA. While there is significant difference between countries, approximately 30% of children in custody globally have ADHD. This compares with 7% in the general population globally.

While just 0.7% of children in the general population have foetal alcohol spectrum disorders, these affect 11% to 21% of children in custody. Foetal alcohol spectrum disorders are a range of cognitive, behavioural and physical conditions which can affect a child as a result of their mother drinking alcohol during pregnancy.

Some children in custody may have very complex needs, with multiple overlapping conditions. Additionally, children may have needs that don’t quite meet diagnostic criteria for any one condition but still have a significant impact on their lives. These children have often had disrupted educational backgrounds, with multiple school moves or periods of absence. This means that they also may not have had their needs identified in school.

Why is this happening?

Of course, having a neurodisability in no way makes children inherently criminal. The majority of children with special educational needs will never come into contact with the youth justice system. So what is it that makes this small group who do more vulnerable?

School exclusion appears to be a really key component in pathways into the justice system for these children. My research with colleagues explored rates of neurodisability and school exclusion in prisoners in Wales. We found that those who scored more highly on a measure of neurodisability were also more likely to have been excluded from school. Those who had been excluded from school were also more likely to have had their first conviction at a younger age.

This finding aligns with Department for Education statistics, which indicate that exclusions are disproportionately affecting children with an identified special educational need. Children with special educational needs represent just around half of all permanent exclusions in England. However, they represent only about 17% of the mainstream school population.

There is plenty of convincing evidence that school exclusion is harmful, and increases the chances of children ending up in the criminal justice system.

Despite this, many accounts report a concerning rise in the use of zero-tolerance behavioural policies in the UK. This could be linked with a rise in the rates of school exclusions reported in the most recent Department for Education statistics.

In 2023-24 there was a 21% increase in the use of fixed-term exclusions (sometimes called suspensions) in England from the previous year. There was also a 16% increase in permanent exclusions.

Combined vulnerabilities

Children who end up in the youth justice system often have multiple other disadvantages layered on top of this systematic exclusion from school. For example, my recent study with colleagues used data from half a million children in the UK. We found that child poverty compounded the likelihood of having contact with the youth justice system for children with neurodisability. This means that it was children who had both disadvantages who were most vulnerable.

This growing body of evidence demonstrates that society is failing these children. When children with neurodisability and complex social disadvantage continue to be punished and excluded, we can’t be surprised when they end up on the fringes of society.

There are ways to remedy the problem of school exclusion. These include more specialist classrooms and units, as well as providing teachers with more options and support for children who aren’t thriving in the mainstream classroom.

In addition, more can be done to remove the layers of disadvantage that these children experience. More generous family welfare policies might help to lift children out of disadvantage and support them to have a better start in life.

Action like this could divert children away from the youth justice system long before they ever have contact with the police.

US leaders view China as a ‘pacing threat’ − has Washington enough stamina to last the race?

Source: The Conversation – Global Perspectives – By Andrew Latham, Professor of Political Science, Macalester College

U.S. muscle or Chinese strategy — which one will prevail? Fred Lee/Getty Images

When Donald Trump meets with Xi Jinping on Oct. 30, 2025, he won’t just be chatting with any run-of-the-mill leader of a rival nation. Rather, he will be sitting down the with the chief representative of the United States’ “pacing threat.”

In the Pentagon’s lexicon, China has increasingly been presented as a “pacing challenge” or “pacing threat” − that is, a great-power rival against which a nation measures its strength, shapes its strategy and directs its resources across every domain of national power.

The phrase and concept has risen in military and academic circles since the turn of the 21st century. Its use in Washington to describe China dates to at least 2020, when Trump’s then–Secretary of Defense Mark Esper used it in a speech in Honolulu.

But what does it mean? For a country to be seen as a pacing threat, it must be a rising yet already near-peer whose capabilities and ambitions directly challenge the dominant country’s global position. A pacing threat doesn’t merely aspire to catch up; it sets the tempo of competition.

Esper’s successor in the Biden administration, Lloyd J. Austin III, continued to call China a “pacing threat,” explaining: “It means that China is the only country that can pose a systemic challenge to the United States in the sense of challenging us economically, technologically, politically and militarily.”

Use of “pacing threat/challenge” has grown since 2009 (Ngram)

The significance goes beyond rhetoric. By defining China in these terms, Washington reorients its entire defense establishment around a new strategic benchmark. The U.S.’s defense planning, industrial policy and global posture now revolve around a single question − how to keep up with and, if necessary, outpace Beijing.

When the United States government signals to its military leaders and industrial partners that a specific country is a “pacing threat,” it is giving them a yardstick by which to judge every dollar spent, every sailor or pilot assigned and every hour of training and preparation.

Pacing threats, increasing risks

The risk of focusing so intently on one foe is, of course, that there is more than one potential adversary out there. And the concept of a pacing challenge shouldn’t imply that China is Washington’s only competitor or potential enemy.

Other rivals remain in the mix, including Russia, Iran, North Korea and a range of smaller militant groups, that could cause major problems for Washington with or without China’s involvement.

The danger for the U.S. is that in designating China its only pacing threat, it could leave blind spots elsewhere. And the objective for a U.S. leader is not simply to be ready for a potential war with China but to be ready for the next crisis wherever it may emerge.

This goal is complicated by a second risk: the urge to plan for the future at the expense of the present. It is one thing for the U.S. Navy to build a fleet and the Air Force to design a missile for 2035 to ensure that it “outpaces” Chinese innovation. But it is another to have the capability to deter or address, if necessary, a crisis or conflict in 2025.

Developing a long-term force to match or surpass China is an important objective to U.S. political and military leaders, but not at the expense of current capabilities.

If the United States is intent on remaining the world’s predominant economic, diplomatic and military force, then it must focus on both – but that is easier said than done.

Is China already ahead?

There are some who believe that America’s pacing threat has already outpaced its rival.

The United States already lags behind China in the scale and output of its defense-industrial base – particularly in the quantity of ships, missiles and other military hardware it can produce and field at speed.

China is building warships at a rate unseen in the U.S. for decades. And it has an industrial ecosystem that can deliver on new programs and scale up in a crisis.

By contrast, American factories face labor shortages, a lack of modern shipyards and glacial acquisition timelines.

If the U.S. is intent on fielding better military assets in the future, it needs them to upscale at a speed that can deter China. In other words, America’s deterrence to any pacing threat needs to start at the factory gate.

A contest of speed, not size

Facing China as a pacing threat will start with an honest U.S. accounting of the type of competition in which it is engaged. This is not merely a rivalry of fleets or firepower but a contest of tempo − who can innovate faster, build smarter and field more flexibly to shape a world in motion.

If the U.S. is to outpace China, it will likely need to reconnect its economic and industrial base to its defense posture and regenerate the productive capacity that made America the world’s arsenal.

But that task is far harder for democracies, where political cycles, fiscal constraints and public skepticism about militarization often slow the mobilization of national power.

Complicating the matter is the fact that the next great arsenal will be defined not just in steel but in data, design and decision. Here, too, China at present appears to be gaining an upper hand. A September report by the Washington-based Information Technology and Innovation Foundation assessed that China was now “dramatically outperforming the United States in the vast majority of critical technological fields.”

The U.S. will not stay ahead of its pacing threat by meeting China ship for ship or system for system. The real edge is in responsiveness − the ability to outthink, outproduce and outmaneuver its competitor.

How Turkey is cracking down on the media

Source: The Conversation – UK – By Massimo D’Angelo, Research Associate in the Institute for Diplomacy and International Affairs, Loughborough University

Hakan Tosun, a 50 year-old Turkish journalist, died on October 13 three days after he was assaulted in a street attack in Istanbul. Two people have been arrested. The motive for the attack remains unclear, but several political groups have suggested that it may be linked to Tosun’s work. He reported on human rights and environmental protection.

Tosun’s case starkly illustrates the dangers faced by journalists in Turkey. Reporters Without Borders ranks Turkey 159th out of 180 countries worldwide for press freedom after roughly 170 journalists have been killed, detained or reported missing there since 2013.

And during the latest democratic crackdown, which followed the arrest of Istanbul’s mayor and leading Turkish opposition figure Ekrem İmamoğlu in March 2025, further arrests have targeted reporters.

Turkey: a favourable international climate is spurring Erdoğan’s crackdown on democracy


Working as a journalist in Turkey has long been dangerous. Hrant Dink, the Turkish-Armenian editor of the Agos newspaper, was shot dead in Istanbul in 2007. Retrials led to the conviction of multiple officials and accomplices, with nine life sentences handed down in February 2025.

In February 2022, Güngör Arslan, the editor of a local news outlet called Ses Kocaeli, was also killed in an ambush outside his office in the city of İzmit. The gunman, Ramazan Özkan, and the instigator, a businessman called Burhan Polat, received life sentences from Turkish courts in 2023.

Beyond these killings, there have been high-profile cases of arrests and persecution. Laws have also been introduced to curb press freedom, including one in 2022 enabling Turkish courts to sentence people found guilty of intentionally publishing disinformation to three years in prison.

Turkish authorities have repeatedly relied on criminal statutes to target critical journalists. Ahmet Şık, an investigative reporter for the Cumhuriyet newspaper, was charged with terrorism-related offences in 2011 and then again in 2016. He was held in pre-trial detention for around a year on both occasions, which the European Court of Human Rights subsequently found violated convention rights.

Ahmet Altan, a prominent Turkish journalist, was also arrested in 2016 on terrorism-linked charges and spent more than four years in prison. Turkey’s Court of Cassation ordered his release in April 2021.

The former editor of Cumhuriyet, Can Dündar, lives in exile after being sentenced in absentia to over 27 years for his reporting on links between Turkey’s national intelligence organisation and the smuggling of weapons to rebel forces in Syria.

And in 2022, broadcaster Sedef Kabaş was jailed and then sentenced to two years and four months for “insulting the president”. She was subsequently released after her sentence was suspended by an appeals court.

Levers of media control

Over more than two decades in power, the government of Turkey’s president, Recep Tayyip Erdoğan, has honed three core strategies to tighten its control over the media industry.

First, there are forced takeovers and trusteeships. This is when courts remove a critical outlet’s managers and install state-approved “trustees” to run it. Editorial lines usually change overnight and, in some cases, the outlet is later shut down.

Bugün TV and Kanaltürk were raided in 2015 and taken over by the Turkish authorities. They had their media assets closed in 2016. Zaman, once Turkey’s biggest daily newspaper, was also seized in 2016 and had its editorial line flipped overnight. These measures sat alongside mass closures under emergency decrees after 2016.

Second, there is ownership concentration via government-friendly conglomerates. Here the tools are buyouts and mergers. Big, politically connected business groups acquire major newspapers and TV channels, bringing them into pro-government orbit.

In 2007, the Sabah-ATV media group was seized by Turkey’s state fund and then sold to the Çalık Group in 2008. Çalık was at the time headed by Erdoğan’s son-in-law, Berat Albayrak, with state bank financing. Sabah-ATV was subsequently passed to a company owned by the government-aligned Kalyon Group in 2013.

Several years later, in 2018, Doğan Media Group – which includes Hürriyet, CNN Türk and Kanal D – was sold to Demirören Holding. The Demirören family, who own the company, openly support Turkey’s ruling Justice and Development party and reportedly have close ties to Erdoğan.

And third, there is regulatory and economic pressure. Even where outlets remain independent, regulators and funding levers can keep them in line.

Turkey’s Radio and Television Supreme Council has repeatedly issued heavy fines and temporary bans against TV channels such as Tele1, Halk TV and Sözcü TV. The state advertising agency, BİK, has also suspended public-advertising eligibility for critical papers such as Evrensel. Extensive online blocking further chills independent reporting.

Alongside squeezing independent outlets, Ankara has poured resources into the state broadcaster TRT – especially its English-language arm, TRT World – to amplify the government’s message abroad.

TRT World has expanded studios and bureaus since launching in 2015, notably in London and Washington. It has also grown its correspondent network and has invested heavily in 24/7 TV, digital video and social platforms.

The aim is to shape global narratives on Turkey’s terms, whether on the Ukraine war, Middle East diplomacy or migration. This has created a striking asymmetry in the Turkish information environment, where domestic dissent is constrained while the government’s international voice is amplified.

Why outside pressure has faded

A convergence of tactics – criminal prosecutions, court-imposed trusteeships, politically connected takeovers, sustained regulatory and financial pressure, and investment in friendly networks – has produced a media sphere in Turkey in which critical voices survive only precariously.

Internationally, however, Ankara now appears closely aligned with the west. While the EU and US sharply criticised democratic backsliding after protests in 2013 and the purges of 2016 that followed an attempted coup, few western governments confront Ankara today.

This is largely because Turkey is pivotal to Nato’s posture in the war in Ukraine, a key guarantor of the Middle East peace agreement and is central to refugee management.

At the same time, Washington is unlikely to lead by example when it comes to supporting journalistic independence. The US president, Donald Trump, has repeatedly attacked media outlets he deems hostile, including public broadcasters, and has also sought to sideline outspoken critics. This is hardly a platform for consistent press-freedom advocacy.

These strategic dependencies blunt external willingness to challenge domestic crackdowns in Turkey. Unless Turkey’s allies make media freedom a genuine condition of engagement – and not an afterthought – this constrained information environment will persist.

Netflix’s A House of Dynamite sounds the nuclear alarm, but how worried should we be?

Source: The Conversation – UK – By Mark Lacy, Senior Lecturer, School of Global Affairs, Lancaster University

As a teenager in the 1980s, I was shown a BBC drama in school called Threads that depicted the impact of a nuclear strike on a city in northern England. Threads is a brutal vision of a terrifying reality that I imagine haunted many people in the years before the end of the cold war.

For younger generations who have so far experienced a world with pandemic lockdowns, wars in Ukraine and Gaza, and international tensions that make a third world war no longer feel like a fictional scenario, geopolitical fear and anxiety is again hard to escape. And now we have a film showing us how a nuclear war could begin.

From three different perspectives, Kathryn Bigelow’s new Netflix thriller, A House of Dynamite, shows us how officials in the US might respond if it looked like a nuclear strike was imminent. Each perspective reveals a different element in the horror and complexity of the situation, as officials work to determine who is responsible and how to manage the attack.

Central to this complexity is the sense of what Prussian general and philosopher of warfare Carl von Clausewitz described as the “fog of war”. This term was devised to describe the uncertainty and chaos of the battlefield in 19th-century wars, but it is applicable to the traumatic situation policymakers find themselves thrown into in A House of Dynamite.

The fundamental problem for all of the officials in the film is that they lack certainty on the origin of the attack. Was the missile launched by Russia, China or North Korea – or could it be Russia manufacturing uncertainty so the US thinks it was North Korea? The question then moves on to whether North Korea even has the military or technical capability to launch such an attack.

With a strike on Chicago looking increasingly certain, officials soon begin to grapple with how the US should respond. The president is shown the “nuclear football”, which allows him to authorise a retaliatory nuclear strike. And his aide takes him through a menu of responses, with each labelled “rare”, “medium” or “well done”.

The president, played by Idris Elba, is shocked by the absurdity of the strategic language and concepts – as much of the audience will be too. The film shows the personal horror that is felt by people having to take decisions that make the scenarios and simulations they trained for real.

Some officials suggest waiting to see what happens before responding. As a security council staff member remarks, there’s always a chance the warhead could malfunction upon impact. Others say the strike might be a test to see how the US responds – and thus a precursor to something far worse. The dilemma facing US leadership, the security council staffer says, is “surrender or suicide”.

The official trailer for A House of Dynamite.

The film’s opening credits imply that a nuclear strike on the US is not a far-fetched scenario, telling us that the era when world leaders wanted a planet with less nuclear weapons “is now over”. But how far are we from this terrifying situation becoming a reality?

One of the most controversial issues in the film is why North Korea, Russia or China would take a course of action that would result in retaliation so severe that it could leave their territories as apocalyptic wastelands. China and Russia, in particular, appear far more comfortable in today’s complex world of overlapping alliances and economic entanglement than many western countries.

The North Korea expert in the film, Ana Park, explains that Pyongyang possibly could afford to risk launching a strike on the US because of its defensive systems. But the belief of a regime that it could survive retaliatory responses from the US and its allies is almost certainly wishful thinking – no matter how sophisticated those defences are.

It’s also not clear whether any leader, regardless of the type of regime, would actually be able to embark on this course of action. Military generals, for example, might intervene. And perhaps most importantly, current assessments suggest that North Korea does not have the capabilities to launch an attack resembling the one portrayed in the film anyway.

Command and control

Another element in the film is the focus on how an attack on the US would involve disrupting the “command and control” structures of the state. US officials raise concerns that its communication and surveillance systems may have been sabotaged by hackers and AI tools, leaving them in a situation where they lack crucial intelligence about the attack and are unable to trust the information they are receiving.

In this sense, A House of Dynamite gives a convincing insight into the mix of tactics that could be used in a complex global crisis in the 21st century. Sabotaging the tools used to make communication faster, and “situational awareness” more detailed and granular, is likely to be a major method for sowing uncertainty and confusion in the years ahead.

In this age of hybrid warfare – which involves methods to disrupt and sabotage an opponent’s activities without engaging in open hostilities – part of the problem is uncertainty about who is doing what. This has been evidenced in the drone disruption and cyber-attacks we have seen across Europe in 2025.

Another issue is unease over what might be possible in future, when the rapid pace of technological change is constantly introducing new forms of sabotage, disruption and destruction.

A House of Dynamite gives an insight into the uncertainty of security and defence in times of hybrid war. But the more immediate strategic dilemma policymakers face in the film – how to respond to a nuclear attack – is probably not an imminent geopolitical reality.
