Gardening in a changing climate

Projected UK temperatures

Changes in UK temperature (°C) compared to 1961-1990 averages in the 2020s, 2050s and 2080s in summer and winter. Even with global emissions reduced to less than today’s levels, summer temperatures in the South East are set to rise by up to 3°C (5°F). If nothing is done to control greenhouse-gas emissions, by 2080 average summer temperatures could rise by 5°C (9°F), and 3°C (5°F) in winter.
Top row: low-emissions scenario.
Bottom row: high-emissions scenario.
