SPECIAL: Schellnhuber presents "10 Must-Knows on Climate" at COP23

Photo Schellnhuber presents 10 Must-Knows on Climate at COP23 From accelerating sea-level rise and ocean acidification to increasing risks of extreme weather events and the "collision course" with Earth’s climatic tipping points - PIK director Schellnhuber presented "10 Must-Knows on Climate Change from Science" today at COP23 in Bonn, together with UNFCCC Executive Secretary Patricia Espinosa, Wendy Broadgate from Future Earth, and Johan Rockström from the Earth League. They addressed policymakers and the public to show that achieving the Paris Agreement is necessary and possible. "Some crucial climate-change facts tend to get lost in the noise of daily deliberations - even at an event such as the UN climate summit. So it is important to remind everyone of the very reason why ten thousands of people meet in Bonn: unprecedented risk to humanity due to global warming, as revealed by science", says PIK director Schellnhuber.

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.

Ending tax breaks after the diesel scandal

Ending tax breaks after the diesel scandal

09/19/2017 - In response to the diesel scandal, the diesel tax advantage should be completely abandoned within the European Union (EU). In Germany, for example, diesel would then be about 20 cents per liter more expensive at the pump. In return, however, this measure would allow Germany but also France to reduce the emissions of CO2 and nitrogen oxides (NOx) by about 10 percent over five years. This is because diesel drivers in particular are much more sensitive to fuel price changes than previously assumed: a price hike of 20 cents per liter would lower their overall consumption by an estimated 14 percent.

A Brief History of CO2 Emissions – new film online

A Brief History of CO2 Emissions – new film online

Extending periods of changing weather, rising sea levels, shifting vegetation zones, even economic losses, social upheaval, and migration of people across the world – these are the effects of global CO2 emissions. The short film “A Brief History of CO2 Emissions” shows how greenhouse gases impact global warming – and our future. The animated short film of the Urban Complexity Lab and the Potsdam Institute for Climate Impact Research (PIK) is now available online.

Cities and Climate Conference: International experts discuss a sustainable future for cities

Cities and Climate Conference: International experts discuss a sustainable future for cities

09/14/2017 - More than 150 city experts from all over the world will come together next week in Potsdam to discuss the future of our cities under climate change. Cities are at the center of the global climate change problem. Not only are they the origin of large amounts of greenhouse gas emissions, they are also vastly affected by the impacts of climate change – like extreme weather events that generate high socioeconomic costs. The ‘Cities and Climate Conference 2017’, which is taking place from the 19th-21st of September 2017 in Potsdam, will therefore discuss how cities of the future can become more sustainable and resilient.

Edenhofer ranked as Germany's top climate economist

Edenhofer ranked as Germany's top climate economist

09/13/2017 Amongst Germany's most important economists Ottmar Edenhofer once again scored excellently in a ranking done by the Frankfurter Allgemeine Zeitung (FAZ), one of the country's most influential newspapers. He turned out to be the only researcher investigating climate and environmental issues in the group of top economists. For the third time in a row he improved, moving up to the 11th rank this year.
