Government urged to prepare for 2°C global warming by 2050
The UK government has been urged to prepare for a future shaped by at least 2°C of global warming by mid-century, as climate advisers warn that current efforts to adapt are falling short of rising risks.
In a letter to policymakers, the Climate Change Committee (CCC) said the country is already struggling to cope with existing climate impacts and is “not yet adapted” to the worsening extremes being experienced today—let alone those expected in the coming decades.
The committee recommended that the UK plan beyond the temperature targets outlined in the Paris Agreement, arguing that preparation should be based on more severe but increasingly plausible warming scenarios. It also called for a clearer long-term strategy, including measurable goals updated every five years and stronger accountability across government departments.
The warning comes amid new data from the World Meteorological Organization confirming that 2024 saw a record increase in atmospheric carbon dioxide levels—the primary driver of human-induced climate change. Scientists say rising greenhouse gas concentrations are intensifying heat, drought, and extreme weather events worldwide.
According to the CCC, a 2°C warming scenario would significantly reshape the UK’s climate. The country could face more frequent and intense heatwaves, prolonged droughts, heavier rainfall, and extended wildfire seasons reaching into autumn.
Baroness Brown, who leads the CCC’s adaptation efforts, said the UK is “not keeping up” with the pace of climate risk. She warned that insufficient preparation could have serious consequences for public health, infrastructure, and essential services such as food and water supply.
Recent evidence suggests these impacts are already being felt. Schools have reported rising instances of extreme indoor heat, affecting learning conditions, while healthcare systems and care facilities are increasingly exposed to temperature-related stress.
The CCC’s latest assessment follows an earlier report stating that the UK’s adaptation progress has been too slow, stalled, or even moving in the wrong direction. A more detailed roadmap outlining trade-offs and adaptation strategies is expected in 2026.
Meanwhile, observed climate trends continue to underline the urgency. The UK recorded its hottest summer on record in 2025, with multiple official heatwaves. Analysis by the Met Office indicates that such extreme heat events are now far more likely due to human-driven climate change.
Globally, scientists warn that carbon dioxide levels are at their highest in millions of years, reinforcing concerns that without rapid emissions cuts, warming will continue to accelerate. Experts stress that alongside mitigation efforts, robust adaptation planning is essential to reduce the growing risks posed by a changing climate.
