Press Release by the International Institute for Applied Systems Analysis and the Potsdam Institute for Climate Impact Research 05/21/2015 A new study analyzes the required climate policy actions and targets in order to limit future global temperature rise to less than 1.5 degrees Celsius by 2100. This level is supported by more than 100 countries worldwide, including those most vulnerable to climate change, as a safer goal than the … Read more What would it take to limit climate change to 1.5°C?

Towards a new industrial revolution: studying societies’ metabolism

Press Release by the Potsdam Institute for Climate Impact Research 05/19/2015 To achieve a lasting transition towards sustainability, large-scale conversion of our built environment – cities, transport systems, power generation – is key. This is an outcome of a special feature investigating advances in the research on industrial ecology, to be published in the Proceedings of the US National Academy of Sciences (PNAS) and coordinated by the Potsdam Institute … Read more Towards a new industrial revolution: studying societies’ metabolism

Gulf Stream in Trouble

Press Release by the Potsdam Institute for Climate Impact Research 03/24/2015  Atlantic Ocean overturning found to slow down already today The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards.  Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe. Scientists now found evidence for a slowdown of the overturning – multiple … Read more Gulf Stream in Trouble

Summer storm weakening leads to more persistent heat extremes

Press Release by the Potsdam Institute for Climate Impact Research 03/13/2015 – Embargo lifted Storm activity in large parts of the US, Europe and Russia significantly calmed down during summers over the past decades, but this is no good news. The weakening of strong winds associated with the jetstream and weather systems prolongs and hence intensifies heat extremes like the one in Russia in 2010 which caused devastating crop … Read more Summer storm weakening leads to more persistent heat extremes

Four of nine planetary boundaries now crossed

Press Release by the Potsdam Institute for Climate Impact Research  01/16/2015 Four of nine planetary boundaries have now been crossed as a result of human activity, says an international team of 18 researchers in the journal Science. The four are: climate change, loss of biosphere integrity, land-system change, altered biogeochemical cycles. The scientists say that two of these, climate change and biosphere integrity, are “core boundaries” – significantly altering … Read more Four of nine planetary boundaries now crossed

Lima Climate Summit

Starting Monday, at the UN climate summit COP20 in Lima delegates from more than 190 nations will discuss a new climate agreement. On this issue, Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research: “Two great challenges define the 21st century – the threat of catastrophic climate change and the maddening gap between the global rich and poor. These biggest challenges to worldwide peace are closely … Read more Lima Climate Summit
