Tipping risks from overshooting 1.5 °C can be minimised if warming is swiftly reversed

  2024-08-01 (or before) in Potsdam Institute for Climate Impact Research

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 ...

Future floods: Global warming intensifies heavy rain – even more than expected

  2024-01-08 (or before) in Potsdam Institute for Climate Impact Research

11/27/2023 - The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis by researchers from the Potsdam Institute of Climate Impact Research (PIK) shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming – meaning that extreme rainfall could increase quicker than climate models suggest.

500+ pages, 200+ researchers: Global Tipping Points Report delivers comprehensive assessment of tipping point risks and societal opportunities

  2023-06-12 in Potsdam Institute for Climate Impact Research

12/06/2023 - Tipping points pose some of the biggest risks to our planet’s life-support systems and the stability of our societies. In an unprecedented effort by the scientific community, researchers have now published a comprehensive report on Earth system tipping points and their potential impacts and opportunities for societal change. More than 200 scientists from around the world contributed to the ‘Global Tipping Points Report’. The report with more than 500 pages provides an authoritative guide to the state of knowledge on tipping points, explores opportunities for accelerating much needed transformations...

Overshooting climate targets could significantly increase risk for tipping cascades — Potsdam Institute for Climate Impact Research

  2023-01-03 (or before) in Potsdam Institute for Climate Impact Research

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.

Planetary boundaries update: freshwater boundary exceeds safe limits — Potsdam Institute for Climate Impact Research

  2022-04-28 (or before) in Potsdam Institute for Climate Impact Research

04/26/2022 - A reassessment of the planetary boundary for freshwater indicates that it has now been transgressed, according to an international team of researchers led by the Stockholm Resilience Centre and including the Potsdam Institute for Climate Impact Research. This conclusion is due to the inclusion of “green water” – the water available to plants – into the boundary assessment for the first time.
