North Atlantic ocean circulation is key to understanding uncertainties in climate change predictions
The accuracy of climate predictions depends crucially on how the ocean circulation of the North Atlantic is incorporated into climate models, a TiPES-study shows Thirty state-of-the-art IPCC-climate models predict dramatically different climates for the Northern Hemisphere, especially Europe. An analysis … Continued
Trust the machine – it knows what it is doing
New theoretical insights provide a physically sound understanding of machine learning-based simplified climate models Machine learning, when used in climate science builds an actual understanding of the climate system, according to a study published in the journal Chaos by Manuel … Continued
Part of the Greenland ice sheet may be close to a tipping point
An analysis of the melt situation on the Central-Western Greenland ice sheet reveals clear signs of tipping Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals the distinct mark of this part of the ice sheet … Continued
Mathematicians find core mechanism to calculate tipping points
Identifying tipping points in the Earth System is crucial for understanding the consequences of climate change. Researchers at the Technical University of Munich (TUM)and part of the TiPES project have discovered a universal mathematical structure at tipping points. It creates … Continued
Anna von der Heidt receives large personal grant on a topic related to TiPES
Congratulations to Anna von der Heidt of Utrecht University who today received the Dutch Research Council, NWO’s Vici grant worth 1.5 million Euros. “A reliable risk assessment of abrupt climate change under the current global warming is urgently needed. For … Continued
Steady now: Unfortunate timing and rate of change may be enough to tip a climate system
Unpredictable, abrupt changes to the Earth’s system of ocean currents could commence from rate-induced tipping, model study shows. ”The findings point to fundamental limitations in climate predictability,” authors warn. Imagine abrupt shifts of the tropical monsoons, reductions in Northern Hemisphere … Continued
Frerk Pöppelmeier recieves Marie Curie grant
A huge congratulations to TiPES postdoc Frerk Pöppelmeier who has been granted a Marie Curie grant.
Highlighted by the AGU
The paper Multivariate estimations of equilibrium climate sensitivity from short transient warming simulations in Geophysical Research Letters, by Robbin Bastiaansen, Hank Dijkstra, and Anna von der Heydt has been highlighted by the AGU editors. In the article, Bastiaansen et al. … Continued
Unmatched dust storms raged over Western Europe during Iceage maximum
Reinterpretations of European loess indicate Western Europe might well have been the dustiest region on Earth Every late winter and early spring, huge dust storms swirled across the bare and frozen landscapes of Europe during the coldest periods of the … Continued
Improving long-term climate calculations
A new method reduces uncertainties in computer model estimations of climate change over thousands of years. Climate researchers have found a simple but efficient way to improve estimations of ultimate global warming from complex climate models. The finding is relevant … Continued
