PIK in the Media
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.
Many systems rely on tiny movements in a certain rhythm, PIK-scientist Jürgen Kurths explains. If these oscillations are disturbed, the consequences can be fatal - a blackout in a power grid or even death of the human heart. An international team of scientists developed a new mathematical approach to restore rhythm. Source: Frontline (India), 05.08.2015.
Beneath the rapid warming, CO2 emissions cause an ocean acidification at an unprecedented rate. A new PIK-study states: even with artificial CO2 removal, the oceans will become dangerously acidified - if we do business-as-usual. PIK-scientist Sabine Mathesius and PIK-director Hans Joachim Schellnhuber explain the current results. Source: The Guardian (UK), 03.08.2015.
In advance of the UN Climate Conference in Paris 2015, PIK's chief economist Ottmar Edenhofer speaks about the state of affairs in Climate Protection, about scenarios, opportunities and perspectives for the future.

"Climate tipping points are points of no return, where you cannot stop a process that has been set in motion", explains PIK-scientist Stefan Rahmstorf.

In the last weeks, there have been rumours about a supposed 'mini Ice Age' the earth was heading to, due to solar variations in the next decades. But already in 2011, a PIK study showed: compared to the expected global warming through greenhouse gas emissions, this effect will be marginal. PIK-scientist Georg Feulner argues against the 'mini Ice Age' rumours. Source: The Washington Post (USA), 14.07.2015.
In advance of December's UN Climate Conference, more than 2000 scientists met in Paris to discuss 'our common future under Climate Change'. As one of the world's most influential Climate Scientists, PIK-director John Schellnhuber advertised the divestment campaign and emphasized the necessity of a global social movement to avoid dangerous global warming.

In a new study, a large research team compared the sea-level rise due to polar ice-sheet mass loss during past warm periods. PIK-scientist Stefan Rahmstorf was part of the team and concludes, that the mid-Pliocene is a matching analogy for where we could be headed: even with a 1-2°C higher temperature than today, a 6 meter sea level rise could be the result.

The number of record-breaking rainfalls increases worldwide - related to global warming. A team of PIK-scientists around Jascha Lehmann figured out an innovative method and found out, that at least every tenth rainfall record of the last thirty years stands in direct correlation with climate change.

in Spring 2015, a PIK-study proved: the Gulf Stream is slowing down - in correlation to Climate Change. Capturing these results, scientists from the University of Toronto now revealed additional influencing factors. PIK-scientist Stefan Rahmstorf explains the mechanisms behind this trend, and stresses the necessity to severely cut greenhouse gas emissions. Source: The Washington Post (USA), 29.06.2015.
"that only a broad moral awakening can offer hope of solving them", states PIK-director Hans Joachim Schellnhuber, who shortly presented the new papal encyclical on the environment in Rome. As one of few leading experts, he was consulted by the Vatican in advance of the release. Source: The New York Times (USA), 18.06.2015.

On June 18th, Pope Francis' Environment Encyclical has been released in Rome. What does it mean for the scientific pleading for climate protection?

The world is busy trying to achieve a goal of limiting global warming to 2°C above pre-industrial levels. But there's another view, embraced by many countries, suggesting that a safer target involves limiting global warming to just 1.5 degrees. A new PIK study analyzes possibilities and perspectives.

A new PIK-study states: the Gulf Stream is slowing down. This enormous oceanic circulation system usually carries huge warm water masses to the North Atlantic and hereby determines the mild climate in Western Europe.
