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
If the ice sheet of West Antarctica breaks down, the result can be a stabilisation of the Atlantic ocean current system transporting warm water to the coasts of Western Europe It has been hypothesised, that the tipping of one element … 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
Theoretical work confirms the method used to predict climate tipping is indeed mathematically sound Recently, scientists from the TiPES project have found early warning signals for climate tipping of the Amazon Rainforest, the West-Central Greenland ice sheet, and the Atlantic … 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
Abrupt global climate changes, named Dansgaard-Oeschger events, that appeared throughout the last ice age, likely depended on the atmospheric levels of carbon dioxide (CO2)concentration, study shows Large jumps within the last ice age between cold and warm climate periods in … 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
Data analysis reveals the rainforest is losing resilience and is approaching a critical transition More than three-quarters of the Amazon rainforest has been losing resilience since early 2000, and the rainforest now shows characteristic signs of approaching a tipping point. … Continued
