Climate change study from Potsdam Institute for Climate Impact Research in Germany published in Nature magazine retracted in December 2025. The study is an example of how such research when not done right can misrepresent situations leading to policy errors. Policy error under such misrepresentation can lead to errors such as a policy that excludes adjustments and a dual response to climate change and cost of living crisis attacking both on two fronts necessary today so soon after a disastrous pandemic and people living in scarcity not able to meet heating bills. What happened is that the study made predictions for 2100- which is impossible to do. Studied 1600 regions in the world. Showed decline of economic output by 62% in 2100. Did not mention that excluding Uzbekistan would make the reduction in growth 23%. It shows how overzealous work in one direction or the other can actually hurt the fight to address climate change and also tackle everday concerns like cost of living crisis. Recent reports in WSJ show how the approach of single focus has hurt economic growth in Germany and hobbled its industries. Other reports show how deprived and less deprived areas in the UK (also in the US) sit by side showing how decades of neglect of manufacturing and outshoring of factories have destroyed jobs and destroyed communities across Europe and the US, making them open to scourge such as fentanyl in the Nation's neighborhoods, and creating a climate of despair that feeds into other fears. Such as the fears of the surge of illegal migration promoted by traffickers and the influx of drug trafficking gangs in the Nation's neighborhoods. Such reports are then used by the World Bank and the Congressional Budget Office and central banks of 90 counties in the coalition Network for Greening of the Financial System, leading to distortions in policy actions, destroying the social consensus needed among wide sectors of the population in democracies in the EU and US and worldwide to address climate change and cost of living crises.  Leonie Wenz, from the Potsdam Institute for Climate Impact Research in Germany says-“We broadly agree with the issues raised, and have made corrections to the underlying economic data and to our methodology to address them. These changes are too substantial for a correction of the original article in Nature.”   ...

Everything you might want to know about coffee, where it comes from, how cultivation is changing with climate change and higher temperatures, and the effort to map the coffee genome. With higher temperatures the farming of coffee moves to higher altitudes in coffee growing countries in the tropics, but it is easier to cross breed the 124 varieties to produce a plant that can withstand the change in temperatures and one that can resist fungus.  A coffee fungus and higher altitude rains destroyed much of the crop in Central America including Guatemala. This led to increased migration to Mexico and U.S. of farmers leading up to Mr. Trump's plan to have the National Guard of Mexico police Mexico's border with Guatemala.  Coffee is a sensitive plant and needs cooler weather and water which is found more in the tropics. Growing it in California or in Italy makes it very costly leading to Frinj coffee being sold in California at $16 a cup. Climate change could reduce the area where coffee can be grown by about 50% in the tropical countries from South east Asia to African countries such as Kenya, Uganda, Tanzania and Ethiopia, and in south America Colombia and Brazil, says Climate Institute, Washington DC based climate change experts.   ...

Infratest Dimap polling institute is commissioned by DW.com to find out what Germans think of the refugee policy of chancellor Merkel one year later. In summer 2015 Merkel said on Aug 31, "We can do it."
