The UK's climate has already changed, leading to extreme weather and record-breaking temperatures as the new normal, according to a major report.
Sea levels in the UK have risen faster than the global average, posing a higher risk from storm surges, while wild animals have altered their behaviors, such as giving birth earlier in the year.
The UK has warmed at a rate of about 0.25°C per decade, being approximately 1.24°C warmer than from 1961 to 1990, with hot days becoming more frequent and cold days less likely.
While 2024 had a lack of sunshine in the UK, it was still the fourth warmest year on record, and the frequency of hot days has dramatically increased while cold nights have dropped. Rainfall is also on the rise, raising concerns for flooding, and changes in phenology could impact ecosystems.
