High Level Summary of Statistics Trend Last update: Wednesday, January 29, 2014

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 1910. The average temperature of 2010 in Scotland was the 10th coldest since 1910. In 2013, the average temperature was 0.49°C higher than the 1961-1990 average. 2013 was 0.20°C warmer than 2012, with an average temperature of 7.52°C.

Temperatures in Scotland are projected to continue increasing over the next century, with hotter summers and milder winters. By the 2080s, projected increases in mean annual temperature for Scottish 'regions' range 1 from 1.6°C to 4.5°C, with central estimates from these distributions between 2.6°C to 3.0°C. 2

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.
