Last year marked a turning point for the UK’s climate, with 2025 becoming the hottest and sunniest on record, according to the Met Office. The average temperature hit 10.09°C, surpassing the previous high of 10.03°C set in 2022. This trend is alarming; four of the last five years are now among the warmest since records began in 1884. In fact, every year in the top 10 for heat has occurred within the last 20 years.
Sunshine also broke records. The UK enjoyed over 1,648 hours of sun, eclipsing the earlier record from 2003 by more than 61 hours. The spring featured an “exceptional” amount of sunshine, contributing to this dramatic weather shift.
Mark McCarthy from the Met Office pointed out that this increase in warmth aligns with the consequences of climate change. He emphasized that while not every year will set a record, the impact of human-induced climate change is evident. Bob Ward of the Grantham Research Institute echoed this sentiment, stressing the urgent need to reduce greenhouse gas emissions if we hope to mitigate the growing effects of climate change.
In 2025, the UK faced a series of droughts, with many regions experiencing their driest spring in more than a century. Reservoir levels dropped below 50%, prompting some water companies to impose hosepipe bans. This combination of heat and dryness led to an unprecedented increase in wildfires. Fire brigades recorded at least 12,454 grassland and forest fires from March to May, more than quadrupling the figures from the previous year.
Emily Carlisle, a scientist at the Met Office, explained that prolonged high-pressure systems, along with unusually warm sea temperatures, have kept temperatures elevated. These climatic shifts also led to a record amount of electricity generated from renewables, with wind, solar, and biomass contributing nearly half of the UK’s electricity in 2025.
The situation prompts a broader reflection on climate change’s real-time effects. Recent surveys indicate that a significant portion of the UK population is increasingly concerned about climate-related issues, with many expressing support for stronger environmental policies.
As we look to the future, the challenge remains: moving toward sustainability while dealing with the immediate impacts of climate change. The UK’s target to cut greenhouse emissions by 81% by 2035 and achieve carbon neutrality by 2050 presents a crucial pathway for tackling these pressing concerns.
