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.

G20 policy brief on sustainable agriculture and ending hunger

G20 policy brief on sustainable agriculture and ending hunger

03/31/2017 - In a policy brief for the G20, an expert group urges the governments of the world's leading economies to track progress on the state of food security and, based on this, to scale investment opportunities and target their interventions. Hermann Lotze-Campen, head of the research domain Climate Impacts and Vulnerabilities at the Potsdam Institute for Climate Impact Research, contributed to this report which is part of the Think Tank 20 (T20) process under Germany’s G20 presidency.

Building trust, not hate: When people know each other, cooperation is more likely than conflict

Building trust, not hate: When people know each other, cooperation is more likely than conflict

03/30/2017 - When anonymity between people is lifted, they more likely cooperate with each other. Playing nice can thereby become a winning strategy, an international team of scientists shows in a study to be published in Science Advances. The findings are based on experiments with a limited number of participants but might have far-reaching implications, if confirmed. Reducing anonymity could help social networks such as Facebook or Twitter that suffer from hate and fake news. It might also help in conflicts about environmental resources.

"Turning the US into a Jurassic Park run by dinosaur energy"

03/29/2017 - US President Trump recently signed an executive order to roll back US climate policies. "Donald Trump's attempt to turn the US into a Jurassic Park run by dinosaur energy will eventually fail," comments Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research (PIK).

Weather extremes: Humans likely influence giant airstreams

Weather extremes: Humans likely influence giant airstreams

03/27/2017 - The increase of devastating weather extremes in summer is likely linked to human-made climate change, mounting evidence shows. Giant airstreams are circling the Earth, waving up and down between the Arctic and the tropics. These planetary waves transport heat and moisture. When these planetary waves stall, droughts or floods can occur. Warming caused by greenhouse-gases from fossil fuels creates favorable conditions for such events, an international team of scientists now finds.

Use a “Carbon Law” to achieve net-zero emissions by 2050

Use a “Carbon Law” to achieve net-zero emissions by 2050

03/24/2017 - To bridge the gap between science-based targets focused on cutting greenhouse gases, and national commitments to such efforts, international experts propose in the highly renowned journal ‘Science’ a decadal roadmap strategy for achieving net-zero emissions by mid-century. They base this on a simple “carbon law” of halving anthropogenic carbon-dioxide (CO2) emissions each decade. “A carbon law applies to all sectors and countries at all scales and encourages bold action in the short term,” say Johan Rockström and colleagues. Rockström, Director of the Stockholm Resilience Centre, and Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research, argue that a “carbon law” that links short-term targets to long-term goals will “provide key elements for national and international climate strategies.” Such a broad decadal roadmap would focus on four dimensions: innovation, institution, infrastructure, and investment, and it would encompass sectors such as agriculture, construction, finance, manufacturing, and transport.

Climate policy brief for G20 finance ministers

Climate policy brief for G20 finance ministers

03/17/2017 - In a policy brief for the G20 finance ministers, an expert group led by Ottmar Edenhofer proposes low-carbon growth stimulation through a steep increase in sustainable infrastructure, mobilizing sustainable finance, and adoption of carbon pricing. This would simultaneously achieve the objectives of the Paris Agreement and the Sustainable Development Goals, the experts argue. The Finance minister and central bankers of the world's leading economies meet in Baden-Baden, Germany, this weekend. Edenhofer is chief economist of the Potsdam Institute for Climate Impact Research (PIK) as well as Director of the Mercator Research Institute for Global Commons and Climate Change (MCC).
