Government told to prepare for 2C warming by 2050

A warning from independent climate advisers states that the UK must prepare for increasing weather extremes as a consequence of at least 2C of global warming by 2050. The Climate Change Committee (CCC) emphasized that the country is not adequately equipped to handle the worsening weather extremes currently happening at existing levels of warming, let alone what is anticipated to come. In a letter addressed to the government, the committee expressed the necessity for the UK to adapt to climate change beyond the long-term temperature target outlined in the Paris Agreement.

The CCC recommended that the government establish a framework with clear long-term objectives to mitigate further temperature increases. They proposed implementing new objectives every five years, with departments being held accountable for achieving these goals. The committee announced that further information on potential trade-offs would be available in May 2026 when they release a major report detailing how the UK can adapt to climate change. Their previous report, published in April of this year, highlighted that preparations in the UK for rising temperatures were either too slow, stalled, or on the wrong course.

Achieving “net zero” is a critical global target in the fight against climate change as acknowledged by climate scientists worldwide. The signatories of the Paris Agreement in 2015, including nearly 200 countries, committed to preventing global temperatures from increasing by more than 1.5C above pre-industrial levels. The CCC’s letter outlined that a 2C global warming level would significantly impact the UK’s weather, leading to more frequent and widespread extreme events such as heatwaves, droughts, floods, and extended wildfire seasons. Baroness Brown, chairwoman of the CCC’s adaptation committee, emphasized the necessity of preparing for the escalating climate risks faced by the UK population.

The UK has already witnessed changing weather patterns due to climate change, with four official heatwaves confirmed in 2025 during what the Met Office declared as the hottest summer on record. Met Office climate scientists discovered that a summer as hot as or hotter than 2025 is now 70 times more likely than in a “natural” climate without human-induced greenhouse gas emissions. Baroness Brown criticized Conservative leader Kemi Badenoch for pledging to repeal the UK’s landmark climate change legislation, calling the promise “disappointing” and highlighting the need for a strategy covering both adaptation and mitigation
