The Ripple Factor: Economic losses from weather extremes can amplify each other across the world
27/10/2021 - Weather extremes can cause economic ripples along our supply chains. If they occur at roughly the same time the ripples start interacting and can amplify even if they occur at completely different places around the world, a new study shows. The resulting economic losses are greater than the sum of the initial events, the researchers find in computer simulations of the global economic network. Rich economies are affected much stronger than poor ones, according to the calculations. Currently, weather extremes around the world are increasing due to greenhouse gas emissions from burning fossil fuels. If they happen simultaneously or in quick succession even at different places on the planet, their economic repercussions can become much bigger than previously thought.

New Lancet Countdown Policy Brief for Germany confirms considerable need for action
10/21/2021 - Despite a growing awareness of the situation's seriousness among those with political responsibility, Germany is only inadequately equipped for the health challenges of climate change. This is the conclusion of this year's report on climate and health, which is published annually by experts from the German Medical Association, Charité - Universitätsmedizin Berlin, the Potsdam Institute for Climate Impact Research and Helmholtz Zentrum München.

Unprecedented rise of heat and rainfall extremes in observational data
10/7/2021 - A 90-fold increase in the frequency of monthly heat extremes in the past ten years compared to 1951-1980 has been found by scientists in observation data. Their analysis reveals that so-called 3-sigma heat events, which deviate strongly from what is normal in a given region, now on average affect about 9 percent of all land area at any time. Record daily rainfall events also increased in a non-linear way – on average, 1 in 4 rainfall records in the last decade can be attributed to climate change. Already today, extreme events linked to human-caused climate change are at unprecedented levels, the scientists say, and they must be expected to increase further.

Reducing tropical cyclone impacts: The double benefit of climate protection through both limiting and delaying global warming
09/27/2021 - Increasing global warming from currently one to two degrees Celsius by mid-century might lead to about 25 percent more people put at risk by tropical cyclones, a new study finds. Already today, hurricanes and typhoons are among the most destructive natural disasters worldwide and potentially threaten about 150 million people each year. Adding to climate change, population growth further drives tropical cyclone exposure, especially in coastal areas of East African countries and the United States. Considering the joint impact of climate change and population growth provides an untapped potential to protect a changing world population.

Today’s children to experience two to seven times more extremes than their grandparents
09/27/2021 - Today’s children will be hit much harder by climate extremes than today’s adults, researchers show in the leading journal Science. During their lifetime, a child born in 2021 will experience on average twice as many wildfires, between two and three times more droughts, almost three times more river floods and crop failures, and seven times more heatwaves compared to a person who’s for instance 60 years old today, the researchers find based on data from the Inter-sectoral Impact Model Intercomparison Project (ISIMIP). This is under a scenario of current greenhouse gas emission reduction pledges by governments which will be a topic at the upcoming world climate summit COP26 in Glasgow.

Major Atlantic ocean current system might be approaching critical threshold
08/05/2021 - The major Atlantic ocean current, to which also the Gulf stream belongs, may have been losing stability in the course of the last century. This is shown in a new study published in Nature Climate Change. The Atlantic Meridional Overturning Circulation, or AMOC, transports warm water masses from the tropics northward at the ocean surface and cold water southward at the ocean bottom, which is most relevant for the relatively mild temperatures in Europe. Further, it influences weather systems worldwide. A potential collapse of this ocean current system could therefore have severe consequences.
