Climate: Past, Present & Future

Martin Wegmann

My name is Martin Wegmann and I am currently wearing two hats: Most of my time I am a data steward for the natural sciences community at the University of Bern, supporting our researchers in making their data open and accessible. Part time I am still a climate scientist, working on analysing open climate data and trying to create open data myself. Scientifically, I focus mostly on climate teleconnections, large scale circulation and seasonal climate prediction, but cover time scales from centuries to hours.

Why are we climate scientists? For us, there is a number of reasons: we feel a strong bond to nature, we like to solve puzzles and we want to understand the mechanisms of what we see every day.  And – even if it only manifests at the end of a causal chain – we want to contribute to a just and livable world via working in climate science. Thus, due to distant and abstract state funding ...[Read More]

After decades of observation, one of the profound consequences of anthropogenic global warming is the rapid rise in temperature in the Arctic, refered to as Arctic Amplification. Compared to the mid-latitudes, warming in the Arctic is twice as fast. The reason is mainly due to the positive feedback of a melting cryosphere: Darker surfaces are revealed from melting cryosphere, reflecting less short ...[Read More]
