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
A new method for estimating how much decisions under uncertainty matter suggests that, when the goals of decision-making are set, taking the best decisions (for those goals, under moderate uncertainty) still pays off when the probability of success becomes very … 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
A new analytical tool can help find tipping events back millions of years, potentially improving the understanding of tipping points in the Earth system TiPES-researchers have developed an automated method for the detection and precise dating of abrupt climate events … Continued
Theoretical progress in climate science indicates algebraic topology applied to reduced climate models might help predict if and when the Earth system will tip The Earth’s climate system seems to have shifted abruptly between colder and warmer modes in the … Continued
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
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
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
