The United Kingdom is dangerously unprepared for the reality of rapid global warming and must urgently overhaul its infrastructure and public systems to cope with rising temperatures, flooding, droughts and heatwaves, a major climate report has warned.
The warning comes from the UK’s Climate Change Committee (CCC), which stated that the country was “built for a climate that no longer exists,” highlighting that current homes, hospitals, schools and transport systems were designed for weather conditions that are now rapidly changing due to climate change.
The report noted that about 90% of UK homes are at risk of overheating as temperatures continue to rise, while future summers could see extreme heat levels reaching up to 45°C, far beyond what most buildings are equipped to handle. It also projected a sharp rise in heat-related deaths, potentially reaching up to 10,000 annually by 2050 if urgent adaptation measures are not taken.
According to the findings, river flooding risks could increase significantly, with peak river flows rising by up to 45%, while sea levels are also expected to climb, putting millions of properties in coastal and low-lying areas at risk. The report further warned of worsening drought conditions that could lead to severe water shortages affecting households, agriculture and industry.
The CCC estimated that the UK will need around £11 billion in annual investment to strengthen its resilience against climate impacts, including upgrading water systems, improving flood defences, and retrofitting buildings to withstand extreme heat and rainfall. Without action, the economic cost of climate damage could rise dramatically in the coming decades.
The committee also called for urgent policy changes, including introducing heat protection standards for homes, schools and workplaces, and expanding cooling systems in public buildings such as hospitals and care homes within the next decade.
While the UK government has acknowledged the report, it has yet to commit new funding or detailed measures in response, despite warnings that delays could lead to far greater economic and human losses in the future.
