The UK's climate is now significantly hotter and sunnier than it was in the 20th century, according to a recent report by the UK's Met Office. The report highlights a dramatic shift in the nation's weather patterns, with rising temperatures and frequent extreme weather events. In 2025, the UK experienced its hottest and sunniest year on record, with an average temperature of 10.1°C and 125% of the 1991-2020 average sunshine. Waters bordering the UK also saw unprecedented marine heatwave conditions, with 297 days of such conditions in 2025. The trend shows a warming of about 0.25°C per decade since the 1980s.
Record-Breaking Heatwaves
The UK experienced two unprecedented heatwaves in May and June 2026, with temperatures reaching 35.1°C and 37.7°C respectively. These events set new monthly records for England and highlighted the increasing frequency of extreme heat. The report notes that the number of days above 30°C and nights above 18°C in Greater London has more than quadrupled compared to the period between 1961 and 1990.
Impact on Infrastructure and Economy
The changing climate is having significant impacts on the UK's infrastructure, economy, and daily life. Mike Kendon, climate scientist at the Met Office, pointed out that much of the UK's infrastructure, housing, agriculture, and health systems are based on a climate that no longer reflects current conditions. Companies like Marks & Spencer and Eurostar are already taking steps to adapt, with investments in equipment capable of withstanding higher temperatures.
Why This Matters for Bangladesh
The changes in the UK's climate serve as a stark reminder of the global nature of climate change. Bangladesh, a country highly vulnerable to climate impacts, can expect similar trends of rising temperatures and extreme weather events. This underscores the urgency for Bangladesh to invest in climate-resilient infrastructure and adapt its agriculture and health systems to cope with a changing climate.
