Trend in snow cover extent over the Northern Hemisphere and in Europe

This figure shows satellite-derived time series of snow cover extent for the period 1967–2015 over the Northern Hemisphere (left) and Europe (right). The time series for the Northern Hemisphere is extended back to 1922 by including reconstructed historical estimates.

Cumulative specific net mass balance of European glaciers

The figure shows the cumulative specific net mass balance of selected European glaciers, i.e. the change in glacier mass since the first year of their assessment. The start of the time series varies between glaciers.

Projected change in the volume of mountain glaciers and ice caps in European glaciated regions

The figure shows the projected volume for 2006–2100 of all mountain glaciers and ice caps in the European glaciated regions, derived using a mass balance model driven with temperature and precipitation scenarios from 14 GCMs, in Iceland, Svalbard, Scandinavia and central Europe (consisting of the European Alps and Pyrenees).

Trend in the number of frost-free days

The annual rate of change of frost-free days represents the trend coefficient for long-term changes in the annual number of days with a minimum daily temperature above 0 °C. For example, a value of 1 indicates that the number of frost-free days has increased on average by 1 day per year in last 30 years (period 1985-2014). The analysis is based on the JRC-MARS gridded meteorological data at 25 km resolution.

Annual mean PM2.5 concentrations in 2014

Observed concentrations of PM2.5 in 2014. The map shows the PM2.5 annual mean concentrations. The red and dark-red dots indicate stations with concentrations exceeding the target value (25 μg/m3). The dark green dots indicate stations reporting values below the WHO air quality guidance for PM2.5 (10 μg/m3). Only stations with more than 75 % of valid data have been included in the map
