Massive climate change is avoidable at low cost

05/04/2007 - The third volume of the UN climate report identifies strategies to mitigate global warming. The most serious impacts of climate change can still be avoided. What's more, effective climate protection through the reduction of global greenhouse gas emissions is affordable and makes economic sense. These are the main messages sent out by the latest report published by the UN's Intergovernmental Panel on Climate Change. The findings are based on research carried out by scientists at the Potsdam Institute for Climate Impact Research (PIK). According to the UN report, energy efficiency, renewable energies and carbon capture and storage will all play a key role in cutting emissions. Nuclear energy will play a smaller role.

Surprise during the Search for a Second Earth

06/11/2007 - A team of scientists led by the Potsdam Institute for Climate Impact Research (PIK) investigated the habitability of the planetary system Gliese 581 in the constellation of Libra, 20 light-years away. With the help of a model for the evolution of Earth-like planets coupled with a climate model they were able to demonstrate habitable conditions on the planet Gl 581d, while its smaller brother, Gl 581c, has to be classified uninhabitable.

21st century water management: Calculating with the unknown

02/01/2008 - Climate change is making a central assumption of water management obsolete: Water-resource risk assessment and planning are currently based on the notion that factors such as precipitation and streamflow fluctuate within an unchanging envelope of variability. But anthropogenic change of Earth’s climate is altering the means and extremes of these factors so that this paradigm of stationarity no longer applies, researchers report in the latest issue of “Science”.

Chancellor Angela Merkel: “You should get on politicians nerves"

05/11/2012 - German chancellor Angela Merkel has warned about the consequences of unabated climate change and called on scientists to keep on pushing this topic. “You should be persistent and sometimes get on politicians nerves,” Merkel said at a symposium of the German Advisory Council on Global Change (WGBU) which was founded 20 years ago. Coming to a worldwide agreement on limiting global warming to two degrees would be difficult, and the energy transition would ask for the willingness for change from the German public, the chancellor said. However, not doing anything is no option, she said: “All progress is of little use if we react too slowly. That’s why we should be aware of what is going to happen if nothing happens now. And that is going to be bitter.”
