The US says it will not “under any circumstances” pay reparations to developing countries hit by climate change-fuelled disasters. Climate envoy John Kerry made the remarks at a Congress hearing before flying to China to discuss the issue. Some countries want major economies – which produce the most greenhouse gases – to pay for past emissions. A fund has been established for poorer nations, but it remains unclear how much richer countries will pay. 

Mr Kerry, a former secretary of state, was asked during a hearing before a House of Representatives foreign affairs committee whether the US would pay countries that have been damaged by floods, storms and other climate-driven disasters. 

“No, under no circumstances,” he said in response to a question from Brian Mast, the committee cha...

Some of the most intense marine heat increases on Earth have developed in seas around the UK and Ireland, the European Space Agency (Esa) says. Water temperatures are as much as 3 to 4C above the average for this time of year in some areas, according to analysis by Esa and the Met Office. The sea is particularly warm off the UK’s east coast from Durham to Aberdeen, and off north-west Ireland.

The Met Office says the reason is partly human-caused climate change.

But other, less-understood natural and man-made factors appear to be driving temperatures up further.

The Esa data shows sea water around virtually the entire coastline of the British Isles is warmer than usual.

Scientists warn that intense heat like this can kill fish and other sea life, sometimes on a huge scale.

A natural weather event known as El Niño has begun in the Pacific Ocean, likely adding heat to a planet already warming under climate change. US scientists confirmed that El Niño had started. Experts say it will likely make 2024 the world’s hottest year. They fear it will help push the world past a key 1.5C warming milestone.

It will also affect world weather, potentially bringing drought to Australia, more rain to the southern US, and weakening India’s monsoon.

The event will likely last until next spring, after which its impacts will recede.

For months, researchers have been increasingly confident that an El Niño event was set to emerge in the Pacific Ocean. 

“It’s ramping up now, there have been signs in our predictions for several months, but it’s really looking like i...

Our overheating world is likely to break a key temperature limit for the first time over the next few years, scientists predict. Researchers say there’s now a 66% chance we will pass the 1.5C global warming threshold between now and 2027. The chances are rising due to emissions from human activities plus the El Niño weather event expected this summer. If the world passes the limit, scientists stress the breach, while worrying, will likely be temporary.

Hitting the threshold would mean the world is 1.5C warmer than it was during the second half of the 19th Century, before fossil fuel emissions from industrialisation really began to ramp up.

The 1.5C figure has become a symbol of global climate change negotiations...

Climate change could dramatically reduce life in the deepest parts of our oceans that are reached by sunlight, scientists warn. Global warming could curtail life in the so-called twilight zone by as much as 40% by the end of the century, according to new research. The twilight zone lies between 200m (656ft) and 1,000m (3,281ft). It teems with life but was home to fewer organisms during warmer periods of Earth’s history, researchers found.

In research led by the University of Exeter, scientists looked at two warm periods in Earth’s past, about 50 million years ago and 15 million years ago, examining records from preserved microscopic shells. 

They found far fewer organisms lived in the zone during these periods, because bacteria degraded food more quickly, meaning less of it reached ...

A recent, rapid heating of the world’s oceans has alarmed scientists concerned that it will add to global warming. This month, the global sea surface hit a new record high temperature. It has never warmed this much, this quickly. Scientists don’t fully understand why this has happened. But they worry that, combined with other weather events, the world’s temperature could reach a concerning new level by the end of next year.

Experts believe that a strong El Niño weather event – a weather system that heats the ocean – will also set in over the next months.

Warmer oceans can kill off marine life, lead to more extreme weather and raise sea levels. They are also less efficient at absorbing planet-warming greenhouse gases.

On Monday, the so-called “synthesis report” was published by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), a body made up of hundreds of international scientists from a dizzying array of disciplines. The new report boils down six previous IPCC reports, published since 2018, which pulled together and analyzed thousands of climate science studies. 

It amounts to the most clear-eyed, up-to-date assessment of the climate crisis: how it’s affecting all corners of the world and its systems, and how humanity is faring in its attempts to mitigate disasters and adapt to those that are now unavoidable.

What is key about the IPCC report is that it’s signed off by national governments to confirm that they accept the scientific findings – and will incorporate them...

Earth is hotter than it has been in 125,000 years, but deadly heatwaves, storms and floods amplified by global warming could be but a foretaste as planet-heating fossil fuels put a “liveable” future at risk. So concludes the UN Intergovernmental Panel on Climate Change (IPCC), which started a week-long meeting Monday to distill six landmark reports totalling 10,000 pages prepared by more than 1,000 scientists over the last six years.

Here are some of the main findings from those reports: 

– 1.5C or 2C? – 

The 2015 Paris Agreement called for capping global warming well below two degrees Celsius compared to late-19th century levels.

But a landmark IPCC report in 2018 left no doubt: only the treaty’s more ambitious aspirational limit of 1.5C could ensure a climate-safe world. 

How do we go from protecting eight per cent of marine areas to 30 per cent in less than 10 years? This question is at the heart of a global forum in Canada aiming to save marine ecosystems under threat from overfishing, pollution and climate change.

On the heels of the historic biodiversity agreement signed at COP15 in Montreal late last year, about 3,000 officials, scientists, non-governmental organisations (NGOs) and Indigenous groups are meeting in Vancouver for the fifth International Marine Protected Areas Congress (IMPAC5), which opened on Friday (Feb 4) and runs until February 9.

Scientists have said the meeting is crucial for setting up a framework to reach the agreed target at COP15 of protecting 30 per cent of the planet’s lands and oceans by 2030.

It is an immense st...

Scientists discover the first evidence that marine conservation helps to reduce climate change. Marine protected areas act as a safeguard for oceans, seas, and estuaries. These regions help in the preservation of the plants and animals that are native to these waters, but the advantages of protected areas go well beyond their boundaries. A group of experts describes how marine protected areas support ecological and social adaptation to climate change and help in the sequestration of carbon in a study that was recently published in the journal One Earth. 

“Marine protected areas are increasingly being promoted as an ocean-based climate solution...
