Given the scale of the contemporary environmental problems, one would easily be overwhelmed by the complexity and severity of the situation. PIK-scientist Stefan Rahmstorf explains, why he is optimistic, that humans will be able to turn around global warming. Source: ABC (Australia), 10.11.2015.
"If you invest at scale, inevitably we will end up with much cheaper, much more reliable, much safer technologies in the energy system", concludes PIK-director John Schellnhuber in view of the upcoming UN Climate Conference in Paris. What would change through the implementation of the national climate pledges that were made in advance? Source: The Guardian (UK), 09.11.2015.
In view of the UN Climate Conference in Paris, PIK-scientist Stefan Rahmstorf writes about the insufficient Australian climate pledges, the true cost of fossil fuels and Australia's "fantastic renewable energy resources that make every German envious."

A new PIK-study shows: local destabilization can cause complete loss of West Antarctica's ice masses. PIK-scientist Anders Levermann explains the current results and the connection to rising sea levels in the future - the collapse of the West Antarctic Ice Shield may begin in the next 60 years.

"I think that for the risks to the climate system, things are looking more optimistic than they did a few years ago. The development of renewable energies – wind, solar and others – has really surpassed the most optimistic expectations", comments PIK-scientist Stefan Rahmstorf on the current developments.

The Korean Hoesung Lee shortly became the new chairman of the Intergovernmental Panel on Climate Change (IPCC). In respect of the upcoming negotiations at the UN Climate Summit in Paris, PIK's chief economist Ottmar Edenhofer comments in an interview on the current developments and claims reforms for the future.

A recently published PIK study dealt with the connections between ongoing carbon emissions and long-term sea level rise. PIK-scientist Anders Levermann was one of the authors of the paper. In an interview, he explains the consequences for coastal cities and talks about his worries concerning the upcoming Paris Climate Summit. Source: The Star (Canada), 25.10.2015.
In advance of the 21st UN Climate Conference in December, Daniel Klingenfeld summarizes: "We should not be gambling with the planet – for our own sake." He is the head of director's staff at the Potsdam Institute for Climate Impact Research and explains the concept of climate tipping points, possible consequences of an ongoing global warming and cites the success of the fossil fuel divestment movement.

PIK-director John Schellnhuber was one of the pope's main advisors for his encyclical on environment and climate change, which was released in June. In the forefront of the UN Climate Conference in December, Professor Schellnhuber talks about the state of affairs in climate reserach and climate politics, climate scepticism, and whether democracy can solve the current environmental crisis.

In Spring 2015, a PIK-study proved: the Gulf Stream is slowing down - in correlation to Climate Change. Among other influencing factors, a cooling North Atlantic Ocean due to Greenland ice melt was stated to be the driving force. Given that 2015 will probably have been the hottest year on reords, PIK-scientist Stefan Rahmstorf explains the mechanisms behind this trend. Source: The Washington Post, 24.09.2015.
A new PIK-study states: if all reserves of coal, oil and gas were burned, the entire Antarctic ice sheet would melt, rising the sea level by over 50 meters. "This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it," concludes PIK-scientist Ricarda Winkelmann, who was the leader of the research team.

"Burning the currently attainable fossil fuel resources is sufficient to eliminate the (Antarctic) ice sheet,", resumes a new PIK-study by an international research team led by PIK-scientist Ricarda Winkelmann. But even if we would just continue our current emissions for another 60 to 80 years, the West Antarctic ice sheet could become instable. Source: The Japan Times, 12.09.2015.
"To be blunt: If we burn it all, we melt it all," resumes PIK-scientist Ricarda Winkelmann, who led an international research team that explored the consequences of continuing massive fossil fuel burn for the Antarctic ice sheet. As a result, the sea level rise could speed up to approximately one foot per decade in the next millenia. Source: The New York Times (USA), 11.09.2015.
The burning of all available fossil fuels could lead to a complete melting of the Antarctic ice sheet, as a new study by a research team led by PIK-scientist Ricarda Winkelmann shows. The long-term destabilization can only be avoided, if we do not miss the Two Degree Target. Text in French, Source: La Presse (Canada), 11.09.2015.
All accesible fossil fuel reserves could be burned in about 150 years, if we continue to increase our emissions by the same amount as in the past, states PIK-scientist Anders Levermann. He was part of an international research team that shortly found that this complete fossil fuel burning would lead to a loss of the entire Antarctic ice sheet, rising the sea level in a critical extent.

In advance of the United Nations Climate Conference in Paris upcoming December, the Climate Action Tracker (CAT) examines the pledges for greenhouse gas reduction of the different countries. The CAT is run by several research institutes, including the Potsdam Institute for Climate Impact Research. PIK-scientist Louise Jeffery comments on the interim results.

In a recent study, PIK-scientist Sabine Mathesius and her team modeled the long-term effects of massive geoengineering to remove CO2 from the air. While the atmospheric carbon dioxide levels would decrease, the CO2-caused ocean acidification would remain on dangerous levels for a long-time - due to seawater circulations.

Due to long-term ocean circulations, future artificial removal of even massive amounts of CO2 from the atmosphere will not reverse the CO2-caused ocean acidification for centuries. PIK-scientist Sabine Mathesius and PIK-director Hans Joachim Schellnhuber explain the deep ocean 'memory' and why emissions reductions have immediately to be implemented.

If the CO2 emissions are not going to be reduced, the capture of the greenhouse gas through geoengineering technologies will not be able to prevent the dangerous acidification of the oceans. PIK-scientist Sabine Mathesius and PIK-director Hans Joachim Schellnhuber comment on the results of a new PIK-study about the topic. Text in French. Source: Paris Match (France), 06.08.2015.
