Last year was the warmest on record across Europe, breaking the previous high mark by a considerable distance, say scientists.
Temperatures across the region were more than 1.9C above the long-term average between 1981 and 2010.
The State of the Climate 2020 report from the American Meteorological Society says temperatures in the Arctic are also rising rapidly.
The temperature over land there was the highest since records began in 1900.
