Bringing temperatures back closer to pre-industrial levels sufficiently fast may prevent tipping of the Greenland ice sheet and avoid drastic sea level rise even if critical temperature thresholds are crossed temporarily, a study finds Crossing critical temperature thresholds of the … Continued
Observations and simulations suggest the South American monsoon might be approaching an abrupt transition due to the combined threat of deforestation, fires, and droughts in the Amazon rainforest Using observations and computer modeling Nils Bochow, University of Tromsø, Norway, and Niklas … Continued
During the last 66 million years two events set the scene for further climate tipping and for the evolution of the climate system in particular
International media have featured quite a few stories about tipping points in the climate system. Some of these reports have been worrying. Others are less disturbing. In this blog, you can read about tipping points, why they cause concern among … Continued
Scientists launch an archive of paleoclimate data to facilitate analysis of abrupt transitions in the climate system Earth’s climate has undergone abrupt transitions in the past, which are often linked to the crossing of tipping points. Understanding how and why … Continued
It might be necessary to simulate thousands of years of climate change on large climate models in order to compare and evaluate them reliably An analysis by Robbin Bastiaansen, Anna von der Heydt, the University of Utrecht, the Netherlands, and … Continued
Evidence is mounting that the Earth’s climate system can change abruptly when tipping points are crossed, for example by anthropogenic release of greenhouse gases. We urgently need to understand and predict these abrupt transitions better. A list of priorities for … Continued
A new reconstructed index of sea surface temperatures confirms previous research: The North Atlantic ocean currents appear to be approaching a point of no return, where their strength will inevitably weaken in the coming decades and centuries. Researchers confirm find that the Atlantic Meridional Overturning … Continued
Crossing a tipping point may lead to many other situations than the generally assumed catastrophic outcome. The consequences of crossing a tipping point might often be much more subtle and less severe than generally assumed. That is the conclusion of … Continued
In the last 66 million years, the climate of the Earth is known to have shifted abruptly between four different states; hothouse, warm house, cold house and icehouse. This was documented in 2020 by Westerhold et al. A further analysis … Continued
