Ice loss due to warming leads to warming due to ice loss: a vicious circle
10/27/2020 - The loss of huge ice masses can contribute to the warming that is causing this loss and further risks. A new study now quantifies this feedback by exploring long-term if-then-scenarios. If the Arctic summer sea-ice were to melt completely, a scenario that is likely to become reality at least temporarily within this century with ongoing greenhouse gas emissions from burning fossil fuels, this could eventually add roughly 0.2°C to global warming. This is, however, not in addition to IPCC projections of future warming since these already take the relevant mechanisms into account. Still, the scientists could now separate the effects of the ice loss from other effects and quantify it. The 0.2°C are substantial, given that global mean temperature is currently about one degree higher than in pre-industrial times, and governments worldwide agreed to stop the increase well below two degrees.

Niklas Boers awarded with EGU Outstanding Early Career Scientist Award
10/26/2020 - One of 2021’s Outstanding Early Career Scientist Awards goes to PIK researcher Niklas Boers. Awarded by the European Geosciences Union (EGU), the prize recognizes Boers’ important contributions in the fields covered by the Nonlinear Processes in Geosciences (NP) Division, which is focused on a series of nonlinear paradigms including deterministic chaos, tipping points, predictability and its limits, as well as extreme events.

Larger part of Amazon rainforest at risk of tipping
10/05/2020 A larger part of the Amazon rainforest than previously thought is at risk of crossing a tipping point where it could become a savanna-type ecosystem, according to a new study. The research, based on computer models and data analysis, is published by a team of scientists including Johan Rockström, Director of the Potsdam Institute for Climate Impact Research, in the journal Nature Communications. Rainforests are very sensitive to changes that affect rainfall for extended periods. If rainfall drops below a certain threshold, areas may shift into a savanna state.
