Climate change and cryosphere – A wetter future for the Arctic

The latest climate models show that Arctic precipitation is changing more rapidly than previously projected with an earlier transition to a rainfall-dominated precipitation. This rapid change in precipitation will have huge implications for the Arctic ecosystem as well as those who live within the region. Arctic precipitation change, why is it so important? The rapid change in Arctic climate, from ...[Read More]

Image of the Week — High altitudes slow down Antarctica’s warming

Sophie Berger July 7, 2017

When it comes to climate change, the Arctic and the Antarctic are poles apart. At the north of the planet, temperatures are increasing twice as fast as in the rest of the globe, while warming in Antarctica has been milder. A recent study published in Earth System Dynamics shows that the high elevation of Antarctica might help explain why the two poles are warming at diﬀerent speeds. The Arctic vs ...[Read More]

When it comes to global warming, greenhouse gases – and more specifically CO2 – are the most often pointed out. Fewer people know however that tiny atmospheric particles called ‘black carbon’ also contribute to the current warming. This post presents a paper my colleague and I recently published in nature communications. Our study sheds more light into the chemical make-up of black car ...[Read More]
