Tipping risks from overshooting 1.5 °C can be minimised if warming is swiftly reversed
08/01/2024 - Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 °C of global warming after a period of overshoot. A new study published in Nature Communications indicates that this risk can be minimised if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers from the Potsdam Institute for Climate Impact Research (PIK), the International Institute for Applied Systems Analysis (IIASA) and other institutes write. They analysed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.

This current has a significant influence on climate, particularly in Europe. Stefan Rahmstorf, head of the Earth System Analysis research department at the Potsdam Institute for Climate Impact Research (PIK), outlines the current state of research in a new overview article in the scientific journal Oceanography.

Timely reversal of global warming could prevent Greenland ice sheet tipping
10/18/2023 - The Greenland ice sheet is likely to be more resistant to global warming than previously thought, finds a new study published in the scientific journal Nature. An international team of scientists shows that even if critical temperature thresholds are temporarily crossed by up to 6.5 degrees Celsius until 2100, a possible tipping of the ice sheet and therefore drastic sea level rise over hundreds of thousands of years could be prevented. To achieve this, measures to reduce greenhouse gases would have to be taken as quickly as possible following the critical rise in temperature, so that the temperature can be stabilized at no more than 1.5 degree Celsius above pre-industrial levels in the long term.

Stability inspection for West Antarctica: marine ice sheet not destabilized yet, but possibly on tipping path
09/07/2023 - Antarctica’s vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts from European research institutes has now provided the first systematic stability inspection of the ice sheet’s current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.

Past abrupt changes in North Atlantic Overturning have impacted the climate system across the globe
08/29/2023 - Abrupt climate changes have affected rainfall patterns worldwide in the past, especially in the tropical monsoon region, a new study shows. An international team of scientists used dripstones from globally distributed caves together with model simulations to analyse the global impacts of rapid Northern-Hemisphere temperature increases, the widely studied Dansgaard-Oeschger events, that repeatedly occurred during the last ice age. The comparison of stalagmite and model data shows in unprecedented detail how these abrupt changes and the associated modifications of the Atlantic overturning circulation, AMOC for short, have affected global atmospheric circulation.

Amazon in the firetrap: Deforestation and warming lock rainforest in dry and damaged grassland state
07/12/2023 - Global warming and drastic deforestation could dry out the Amazon rainforest faster and enforce the risk of keeping it downright fire-trapped. A new study published in Nature Communications Earth and Environment shows: Fire can be a decisive factor for a potential tipping of the Amazon rainforest, as it is capable of locking large parts of the Amazon in a treeless state. While naturally not occurring in rainforests, fire can play an increasing role once the forest is damaged, thinned or completely lost, up to a status where fire is the dominating driver of the ecosystem.

Greenland’s Ice Sheet might be close to first tipping point
04/05/2023 - The Greenland Ice Sheet is likely to be halfway towards a tipping point whose crossing would imply extensive further melting, a new study finds. While humanity has emitted ca. 500 gigatons of carbon so far, with about 1000 gigatons of carbon much of the massive ice sheet will melt irreversibly, a team of scientists shows.

Amazon heat drives Tibet temperatures: climate tipping elements connected half around the globe
01/26/2023 - While the Amazon rainforest and the Tibetan Plateau sit on different sides of the globe, scientists now discovered that changes in the South American ecosystem can trigger changes in the vicinity of the Himalayas. Both are tipping elements, hence large-scale elements of the planetary machinery that are sensitive to global warming and may shift abruptly and often irreversibly from one state to another at specific thresholds. A new study applies the theory of complex networks to these elements and finds surprising – and worrying – long-distance linkages.

Overshooting climate targets could significantly increase risk for tipping cascades
12/22/2022 - Temporarily overshooting the climate targets of 1.5-2 degrees Celsius could increase the tipping risk of several Earth system elements by more than 70 percent compared to keeping global warming in line with the United Nations Paris Agreement range, a new risk analysis study by an international team of researchers shows. This tipping risk increases even if in the longer term the global temperature would stabilize within the Paris range. Avoiding an overshoot would hence limit the risks, the researchers conclude.
