Solar radiation, land surface, ice cover, the atmosphere and living things, as well as wind and ocean currents, play a crucial role in the climate system. These factors are intricately connected; changes to some can have significant effects on others, leading to overall consequences for th ...[Read More]

Mikhail Varentsov, a climate and meteor ...[Read More]

The aim of these presentations is to highlight the essence of a particular research area – just enough to get the audience excited about a topic without overloading them with information. What’s gr ...[Read More]
