BRITAIN: EXTREME CLIMATE
BLOOMBERG - October 15, 2025 - The UK should prepare for more extreme weather as the world will likely miss the Paris Agreement’s target to limit global warming, the government’s official climate adviser said.
Britain should brace for warming of at least 2 degrees Celsius by 2050 and as much as 4C by the end of the century, the Climate Change Committee said in a letter on Wednesday. It was responding to a request for advice from the government about likely future climate scenarios.
The Paris agreement aims to keep global warming well below 2C and ideally under 1.5C, compared with pre-industrial levels. Reaching the upper limit will likely make climate impacts worse, said Richard Betts, an expert adviser to the committee and head of climate impacts research at the Met Office.
“The likelihood of high temperatures, higher fire risk, increased flooding and so on, it just keeps going up,” Betts said. It would also mean higher sea levels, which can’t be reversed.
Carbon-dioxide emissions from human activities and wildfires rose by an unprecedented amount last year, while the land and oceans’ ability to absorb carbon diminished, according to a report from the World Meteorological Organization.
The CCC has previously warned that the government’s plans to adapt to climate change are inadequate. The latest gudance comes after the UK sweltered through its hottest summer on record.
Britain’s higher average temperatures are already affecting daily life, with extreme heat posing a threat to health and productivity, according to Julia King, Baroness Brown of Cambridge and the chair of the committee’s adaptation group. There’s also a growing risk to roads and railroads from flooding and heat, as well as damage to crops, including wheat, from heat and extreme rainfalls, she said in a briefing on Monday.
The UK has for years been a leader on climate change and been particularly effective in reducing emissions of planet-warming carbon dioxide. But its green policies have more recently faced strong political push back.
King said there is a danger that the UK’s political consensus on climate change is breaking apart. “It really is very disappointing to see that support fracturing,” she said.
Kemi Badenoch, leader of the UK’s Conservative opposition, said earlier this month that the party would abandon the country’s legally-binding climate change legislation, which sets emissions targets.
