Huge tipping events dominated the evolution of the climate system
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
Climate tipping – what it is, and why it matters
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
System of currents in the Northern Atlantic Ocean estimated to tip mid century
Data analysis suggests that the AMOC, an ocean current system responsible for the relatively mild climate in Western Europe and a cooling of the tropics, will likely shift to a less active state within decades The North Atlantic Overturning circulation … Continued
Understanding climate tipping must be prioritized
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
The Sun’s 11-year cycle cannot explain global warming
An analysis of observational data and a large climate model finds Earth’s 11-year cycle is out of sync with solar fluctuations The Earth’s global climate system fluctuates in 11-year and 3,5-year cycles find Yizhak Feliks, Justin Small and Michael Ghil. The … Continued
Predicting future extreme weather
We know anthropogenic climate change will increase the probability of extreme weather events. But how much and in which regions? Valerio Lucarini and Vera Melinda Galfi demonstrate in Physical Review Letters that it is possible to estimate the probability of … Continued
PaleoJump – a TiPES database for research on rapid climate transitions
PaleoJump is a new TiPES database for research on rapid transitions in paleoclimates by Witold Bagniewski, Denis-Didier Rousseau, Michael Ghil, and Jens Fohlmeister. “Paleoclimate records vary in their origin, nature, quality, and resolution. So, it is a daunting task to … Continued
