Global Atmosphere - Annual Mean Temperature

High Level Summary of Statistics Trend Last update: Friday 10 May, 2019

Annual Mean Temperature

The global average surface temperature has increased over the 20th century by about 0.6°C. In Scotland the average temperature in the 2000's was 0.90°C warmer than the 1961-1990 average and warmer than any other decade since records began in 1910. However, the average temperature for Scotland in 2010 was the 10th coldest since 1910. In 2018 the average temperature was 7.82°C which is 0.79°C higher than the 1961-1990 average. 2018 was 0.22°C cooler than 2017 and 0.41°C cooler than 2014, which was the warmest year on record.

Temperatures in Scotland are projected3 to continue increasing over the next century, with hotter summers and milder winters. By the 2080s, projected increases1  in mean annual temperature for Scottish 'regions' range2  from 1.6°C to 4.5°C, with central estimates from these distributions between 2.6°C to 3.0°C.

Whilst the global impacts of climate change are considerable, there are also wide-ranging implications for Scotland. These include increased flood risk, and impacts on water resources, agriculture, transport, tourism and disease; all of great economic, social and environmental importance.
