The latest analysis of the UK climate, State of the UK Climate 2020 published in The Royal Meteorological Society’s ‘International Journal of Climatology’, has shown that climate change is already being felt across the UK. All of the top-ten warmest years for the UK in records back to 1884 have occurred since 2002, and, for central England, the 21st century so far has been warmer than the previous three centuries.
The last 30-year period (1991-2020) has been 0.9°C warmer than the preceding 30 years (1961-1990). The warming trend is evident across all months and all countries in the UK.
The greatest warming compared to 1961-1990 has been across the east Midlands and East Anglia where average annual temperatures have increased by more than 1°C, with the least warming around western coastal fringes and parts of Northern Ireland and Scotland.
