Rising
global temperatures, ice field and glacial melting and rising

In a study published in the actual volume of Nature Communications, geo - and climate researchers at the Alfred - Wegener Institute, Helmholtz Centre for Polar - and Marine Research (AWI) show that, in the course of our planet's history, summertime

Just as the underlying change in
sea level is swamped by the daily and monthly changes, so the annual variation in

Of course, while short - term changes in

Global warming is desiccating the region in two ways: higher
temperatures that increase evaporation in already parched soils, and weaker winds that bring less rain from the Mediterranean
Sea during the wet season (November to April).
At the time, massive amounts of carbon entered land and
