“We need you”: UN climate chief to Potsdam climate scientists

“We need you”: UN climate chief to Potsdam climate scientists

10/13/2017 - Hundreds of millions of people will be affected by climate change impacts and their implications for health or migration already within the next few decades, sectors that so far often get overlooked in this context. This is one of the insights of the Impacts World Conference organised by the Potsdam Institute for Climate Impact Research (PIK) in Germany this week. About 500 scientists from 67 countries were gathering at the conference with the title “Counting the true costs of climate change” to push climate impact research to the next level by better integrating socio-economic factors. At the same time, the institute celebrated its 25th anniversary hosting this meeting of the global impacts research community, in the spirit of its mission followed for a quarter century: further advancing scientific progress and communicating insights to stakeholders.

Formation of coal almost turned our planet into a snowball

Formation of coal almost turned our planet into a snowball

2017/10/10 - While burning coal today causes Earth to overheat, about 300 million years ago the formation of that same coal brought our planet close to global glaciation. For the first time, scientists show the massive effect in a study published in the renowned Proceedings of the US Academy of Sciences. When trees in vast forests died during a time called the Carboniferous and the Permian, the carbon dioxide (CO2) they took up from the atmosphere while growing got buried; the plants’ debris over time formed most of the coal that today is used as fossil fuel. Consequently, the CO2 concentration in the atmosphere sank drastically and Earth cooled down to a degree it narrowly escaped what scientists call a ‘snowball state’.

Investigating teleconnections of weather extremes: GOTHAM Summer School

Investigating teleconnections of weather extremes: GOTHAM Summer School

09/22/2017 - To investigate teleconnections and their role in causing extreme weather events, twenty-five young scientists from all over the world have been gathering this week at the Potsdam Institute for Climate Impact Research. Firstly, when the weather is changing in one place on Earth, this can influence rain or wind or temperatures in another distant place. Investigating this issue using cutting-edge mathematics is front and centre at this year’s GOTHAM summer school – Globally Observed Teleconnections and their role and representation in Hierarchies of Atmospheric Models.

Winter cold extremes linked to high-altitude polar vortex weakening

Winter cold extremes linked to high-altitude polar vortex weakening

09/22/2017 - When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and can be linked to cold winters in Russia and Europe. It is the first to show that changes in winds high up in the stratosphere substantially contributed to the observed winter cooling trend in northern Eurasia. While it is still a subject of research how the Arctic under climate change impacts the rest of the world, this study lends further support that a changing Arctic impacts the weather across large swaths of the Northern Hemisphere population centers.

Storm Harvey: impacts likely worsened due to global warming

Storm Harvey: impacts likely worsened due to global warming

08/28/2017 - Tropical storm "Harvey" is causing severe flooding in Texas. Because many people are asking if there is a link to climate change, the Potsdam Institute for Climate Impact Research issued a statement by its Earth System Analysis Co-Chair Stefan Rahmstorf. "Harvey" was not caused by climate change, he says. Yet its impacts – the storm surge, and especially the extreme rainfall – very likely worsened due to human-caused global warming.

PIK ranked among top five climate think tanks worldwide

PIK ranked among top five climate think tanks worldwide

07/05/2017 - The Potsdam Institute for Climate Impact Research (PIK) was again ranked among the best climate think tanks worldwide. The new Climate Think Tank Ranking by the International Center for Climate Governance (ICCG) places PIK among the top five climate think tanks globally and among the top three of climate thinks tanks in Europe. Altogether the ranking considers 240 cutting-edge institutions working in the field of climate change economics and policy. Based on a solid quantitative methodology and analytical data, the ICCG lists non-university affiliated think tanks in an absolute and a standardized ranking – the first measures the think tank’s efficiency in per capita/researcher terms, whilst the latter measures performance regardless of their efficiency and hence size.

Turning the Climate Tide by 2020

Turning the Climate Tide by 2020

06/28/2017 - The world needs high-speed climate action for an immediate bending-down of the global greenhouse-gas emissions curve, leading experts caution. Aggressive reduction of fossil-fuel usage is the key to averting devastating heat extremes and unmanageable sea level rise, the authors argue in a comment published in the renowned scientific journal Nature this week. In the run-up to the G20 summit of the planet’s leading economies, the article sets six milestones for a clean industrial revolution. This call for strong short-term measures complements the longer-term 'carbon law' approach introduced earlier this year by some of the current co-authors, including the Potsdam Institute’s Director Hans Joachim Schellnhuber, in the equally eminent journal Science. Thus a full narrative of deep decarbonization emerges.

Climate stabilization: Planting trees cannot replace cutting CO2 emissions

Climate stabilization: Planting trees cannot replace cutting CO2 emissions

05/18/2017 - Growing plants and then storing the CO2 they have taken up from the atmosphere is no viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows. The plantations would need to be so large, they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in the case of substantial failure to reduce emissions. However, growing biomass soon in well-selected places with increased irrigation or fertilization could support climate policies of rapid and strong emission cuts to achieve climate stabilization below 2 degrees Celsius.

Global warming trend with ups and downs, but without slowdown or speed-up

Global warming trend with ups and downs, but without slowdown or speed-up

04/25/2017 - Temperatures worldwide are increasing due to greenhouse-gases from fossil fuels. Past claims of a noteworthy ‘slowdown’ of the global warming trend are proven wrong by statistical analysis, a new study shows. Researchers from Germany and the US examined global-mean surface temperature trends, in the light of the three record breaking years 2014-2015-2016 in most datasets. While there of course is some natural short-term variability, the study finds no significant slowdown let alone ‘pause’ in the upward trend.

Amazon forests: Biodiversity can help mitigate climate risks

Amazon forests: Biodiversity can help mitigate climate risks

29/08/2016 - A forest with greater diversity of plants can better adjust to climatic stress. Now for the first time, a team of scientists can show this in computer simulations of the Amazon region by accounting for its amazing diversity of trees. Biodiversity can hence be an effective means to mitigate climate risks and should not only be seen in the context of nature conservation.
