"Sucking CO2 would not halt Warming Effects"

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.

"The Chemical Echo of this century's CO₂ Pollution"

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.

"La technologie ne sauvera pas les océans"

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.

"If the Rhythm gets disturbed"

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.

"It wouldn’t be enough to save the Oceans"

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.

"We have to take the Right Decisions"

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.

"We could avoid the Greenland tipping point"

"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. How a strong agreement at the UN Climate Conference in Paris end of the year could help avoid passing one more of these points. Source: Deutsche Welle, 17.07.2015.

"There will be no Mini Ice Age"

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.

"We need to have something really disruptive"

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.

"Sea-level rise due to polar ice-sheet mass loss"

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.

"Record-breaking Rainfalls and Global Warming"

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.

"More Torrential Rains worldwide"

A new PIK study proves the global increase of extreme rainfalls over the last decades. PIK-scientists Jascha Lehmann and Dim Coumou about the clear uptrend, the correlations with global warming and greenhouse gas emissions, and about expectations for the future.

"Gulf Stream slow-down: further evidence"

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.

"To keep the World super safe from Global Warming"
