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.

Atmospheric teleconnections drive surge in summer heatwaves
09/27/2024 - Summer heatwaves are four times more likely in some areas in the Northern hemisphere due to atmospheric teleconnections, scientists have found. The study by an international research team, including the Potsdam Institute for Climate Impact Research (PIK), also reveals how long-distance linkages of weather events can account for nearly half of the interannual changes in heatwaves and accurately estimate heatwave trends in 80 percent of the land area in middle to high latitudes. As record-breaking heatwaves have a big impact on society and the economy worldwide, understanding these complex atmospheric dynamics is crucial for developing effective climate adaptation strategies.

Up to 30 percent more time: Climate change makes it harder for women to collect water
06/21/2024 - By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study published in Nature Climate Change. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. A team of scientists from the Potsdam Institute for Climate Impact Research (PIK) estimates the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions. Worldwide, two billion people currently lack access to safe drinking water. The responsibility for collecting water typically falls on women and girls.

38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

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.

Stuck to the subway: less privileged people have fewer possibilities to adapt their mobility behaviour to heat
10/10/2023 - Extreme heat amplifies social inequalities when it comes to subway usage and mobility in big cities, a new study shows. Analyzing the effect of temperature on people’s mobility behavior in New York City, researchers from the Potsdam Institute of Climate Impact Research (PIK) find that especially in low-income areas there are little possibilities for subway users to adapt to and mitigate heat by reducing mobility. This could lead to additional heat stress and increase health risks.

Climate extremes hit stressed economies even harder
08/30/2023 - Economies already under stress respond more strongly to weather events like heat waves, river floods and tropical cyclones, a new study shows. A global economic crisis as during the Covid-19 pandemic strongly amplifies the price increases private households experience from the impacts of weather extremes, a team of researchers from the Potsdam Institute for Climate Impact Research (PIK) finds. The price impacts tripled in China, doubled in the United States and increased by a third in the European Union.

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.

Less predictable rainfall important for Maya decline
03/17/2023 - Reduced predictability of seasonal rainfall might have played an important role in the disintegration of Classic Maya societies about 1100 years ago. That is the result of a new study of the Potsdam Institute for Climate Impact Research (PIK) and Potsdam University. The research team studied variations in stable isotope signatures from a stalagmite that was collected in a cave near Uxbenka/Belize, an important archaeological site in the former heartland of the Maya. The carbon and oxygen isotope ratios are sensitive recorders of local and regional rainfall dynamics.

Earlier, higher, smaller: Climate change alters glacial lake outburst floods
02/16/2023 - Due to global warming, flood-like water outbursts from ice-dammed glacial lakes worldwide happen earlier in the year and originate from higher areas. This is shown on the basis of observation data since 1900 by a new study with the participation of the Potsdam Institute for Climate Impact Research (PIK), which is published in the scientific journal Nature. At the same time, however, these so-called outbursts are also becoming smaller.

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.
