Stefan Rahmstorf, a leading climate scientist at the Potsdam Institute for Climate Impact Research in Germany, said that the new study is “excellent” and is a very convincing explanation for something that has puzzled other researchers for many years. The study, by two researchers who are not climate scientists, is seen as one of the most important insights into the apparent flatlining of global average temperatures over the past 15 years.

The Warsaw meeting will continue work toward a treaty limiting carbon dioxide emissions in all nations. To meet the 2-degree target, about two-thirds of proven fossil-fuel reserves must remain in the ground, mostly coal, according to the Paris-based International Energy Agency. Ottmar Edenhofer, chief economist at Germany’s Potsdam Institute for Climate Impact Research, said in an interview: “There is much more carbon underground than the amount which can still be released if dangerous climate change should be avoided. The challenge is that we have to provide the right incentives to the users of coal, oil and gas to leave a remarkable amount of these fossil fuels underground.” Source: Washington Post, 04.11.2013.
Dieter Gerten of the Potsdam Institute for Climate Impact Research, lead author of the study on water said: "If population growth continues, by the end of our century under a business as-usual scenario these figures would equate to well over 1 billion lives touched," and stresses that "this is on top of the more than 1 billion people already living in water-scarce regions today."

Based on modeling studies by the Potsdam Institute for Climate Impact Research, water scarcity will increase around the world due to climate change, with more than 500 million people affected if mean global warming is limited to 2 degrees Celsius (3.6 degrees Fahrenheit). "Our findings support the assertion that we are fundamentally destabilizing our natural systems,” Wolfgang Lucht, one of the study co-authors, was cited as saying in the statement. “We are leaving the world as we know it.” Source: Bloomberg, 08.10.2013.
Getting hundreds of experts to agree is never easy. Ottmar Edenhofer takes a firm, philosophical approach to the task. A portrait in: Nature, 18.09.2013.

Dim Coumou and Alexander Robinson from the Potsdam Institute for Climate Impact Research have published a paper in Environmental Research Letters examining the frequency of extreme heat events in a warming world. They compared a future in which humans continue to rely heavily on fossil fuels (an IPCC scenario called RCP8.5) to one in which we transition away from fossil fuels and rapidly reduce greenhouse gas emissions (called RCP2.6). Source: The Guardian, 21.08.2013.
"We find that up until 2040, the frequency of monthly heat extremes will increase several fold, independent of the emission scenario we choose to take. Mitigation can, however, strongly reduce the number of extremes in the second half of the 21st century," lead author of a study, Dim Coumou , from the Potsdam Institute for Climate Impact Research , said.

A recent paper, by Anders Levermann of the Potsdam Institute for Climate Impact Research in Germany and a half-dozen colleagues, implies that even if emissions were to stop tomorrow, we have probably locked in several feet of sea level rise over the long term.

A rise in sea levels threatens the viability of more than 1,400 cities and towns, including Miami, Virginia Beach and Jacksonville, unless there are deep cuts in heat-trapping greenhouse gas emissions, says an analysis out Monday. To calculate U.S. cities at risk, it integrated a finding, published last month in a PNAS paper led by Anders Levermann of the Potsdam Institute for Climate Impact Research, that each degree Fahrenheit of global warming translates to 4.2 feet of sea-level rise in the long run (as much as two millenniums.)

Scientists have found a way to forecast El Nino weather events in the Pacific a year in advance, long enough to let farmers plant crops less vulnerable to global shifts in rainfall, a study showed on Monday. "Better forecasting will mean farmers can adapt," Hans Joachim Schellnhuber, head of the Potsdam Institute for Climate Impact Research and a co-author of the report with experts in Russia, Israel, Germany and the United States, told Reuters.
