Green growth: 30 percent of regions worldwide achieve economic growth while reducing carbon emissions
10/29/2024 - More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research found. Their new study highlights the vital role of national climate actions in decoupling economic growth from CO2 emissions. The analysis of data from 1,500 regions over the past 30 years showed that 30 percent have managed to lower their carbon emissions while continuing to thrive economically. While this accelerating trend marks significant progress towards achieving the Paris Climate Agreement, the authors caution that the current pace of decoupling is insufficient to meet the global climate target of net-zero carbon emissions by 2050.

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.

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.

Economic losses from hurricanes become too big to be offset by the US if warming continues
10/17/2022 - Hurricane damages can increase due to increasing global temperatures, caused by greenhouse gas emissions from fossil fuels. Computer simulations of regional economic sectors and supply chains in the US now show that the resulting economic losses can at some point not be nationally offset under unabated warming. If too many factories and the like are hit by the hurricane and stop working, other countries will have to step in to provide the supply of goods, according to the scientists who did the study. The hurricane impacts under global warming will thus give the US an economic disadvantage, the warmer the more.
