The United Kingdom must urgently prepare to cope with the growing and inevitable impacts of climate change, particularly weather extremes aligned with at least 2°C of global warming by 2050, according to advice from the independent Climate Change Committee (CCC). The committee has warned that the country is currently not equipped to handle worsening heatwaves, droughts, wildfires, and flooding, which are already manifesting at the present 1.4°C rise in global temperatures. The CCC has insisted that stronger government action is essential to protect public health, homes, food security, infrastructure, and key public services amid this warming trajectory.

In correspondence with the government, the CCC has recommended setting clear, long-term adaptation objectives, supported by measurable five-year targets to ensure accountability across government departments. It stressed that new infrastructure, including homes and electricity networks, should be designed not merely for the mid-century scenario of 2°C warming but with adaptability for potential temperature rises as high as 4°C by the end of this century. This approach is vital considering the committee's caution that, while the internationally agreed Paris Agreement target to limit warming to 1.5°C is still achievable, prudent risk management must also consider more severe temperature rises and their impacts.

The urgency of this call is underscored by the UK’s recent climate experiences. The summer of 2025 was the hottest on record, following the historic 40°C temperatures recorded in 2022, accompanied by severe droughts, widespread wildfires, and disrupted harvests. These phenomena punctuate a stark reality: the UK is grappling with increasingly frequent and intense climate extremes. The CCC’s analysis projects that with a 2°C rise, the likelihood of heatwaves could double annually, drought durations in England are expected to double as well, peak rainfall and river flows may surge substantially—heightening flood risks—and wildfire seasons will lengthen, moving deeper into the autumn months.

The committee highlights six priority areas critical for adaptation: safeguarding public health, ensuring food security, enhancing the resilience of infrastructure, protecting urban environments, maintaining the continuity of essential public services, and fostering a climate-resilient economy. It insists that vital services such as healthcare and insurance must continue to operate effectively under extreme weather conditions, and cities, towns, and villages should avoid disruption. The planting of trees for carbon storage and urban cooling, for instance, must account for their survival under future climate conditions, emphasising forward-thinking environmental management.

In its broader outlook, the CCC’s 2025 adaptation progress report highlights projected climate changes across the UK, including warmer, wetter winters and hotter, drier summers which will exacerbate flood and drought risks. Sea levels are expected to rise between 10 and 30 centimeters, increasing coastal vulnerability. The committee advocates for comprehensive and coordinated strategies across all sectors to build resilience and reduce exposure to these escalating threats.

Echoing this message, Baroness Brown, chairwoman of the CCC adaptation committee, criticised the political debate surrounding the Climate Change Act, which underpins both mitigation and adaptation efforts. She described Conservative leader Kemi Badenoch's pledge to scrap the Act as “very disappointing,” warning that such moves threaten the bipartisan consensus needed to address climate change holistically. Baroness Brown affirmed that adaptation should be treated with the same urgency as efforts to reduce emissions, emphasising that both are indispensable and complementary.

Alongside adaptation, the CCC continues to press for ambitious emissions cuts to meet net-zero targets by 2050. Its recent recommendations include accelerating transitions to electric vehicles and heat pumps, and reducing meat consumption by 25% by 2040, as part of broader systemic changes to curb emissions while enhancing sustainability. The CCC has also urged a steeper emissions reduction target by 2035, aiming for an 81% cut compared to 1990 levels, reinforcing its commitment to keeping the 1.5°C goal within reach.

Taken together, these recommendations portray a comprehensive strategy: urgent and substantial adaptation is needed now alongside intensified mitigation efforts. Britain’s experience of increasingly severe climate events makes it clear that preparing for at least 2°C of warming—and potentially much higher—in the coming decades is not just prudent planning but an urgent necessity. Without robust, government-led policies that integrate clear targets, accountability, and future-proofing of infrastructure and services, the country risks being overwhelmed by the complex challenges of climate change.
