The Endgame: Climate Change as Weapon

Thinking on these images from Mozambique, Zimbabwe & elsewhere I suddenly realize that what I had only dimly perceived or hadn’t wanted to believe was most likely true: the climate change deniers in power (or even those out of power or refusing to think on this for personal convenience) don’t do this simply out of a combination of obtuseness, stupidity, religiously motivated anti-science idiocy, and personal greed leading them … Read more The Endgame: Climate Change as Weapon

Rainfall extremes are connected across continents: Nature study

Press Release by the Potsdam Institute for Climate Impact Research 31/01/2019 Extreme rainfall events in one city or region are connected to the same kind of events thousands of kilometers away, an international team of experts finds in a study now published in one of the world’s leading scientific journals, Nature. They discovered a global connection pattern of extreme rainfall – this could eventually improve weather forecasts and hence … Read more Rainfall extremes are connected across continents: Nature study

The living lab experiment “Climate-Neutral Living in Berlin” takes stock

Press Release by the Potsdam Institute for Climate Impact Research 31/01/2019The living lab experiment “Climate-Neutral Living in Berlin” takes stock: Everyone can contribute to climate stabilization, but without politics it won’t succeed “Climate-Neutral Living in Berlin” – for one year, more than 100 Berlin households have tried to shift to a more climate-friendly everyday life, from families with children, partners, flatmates to singles. In the living lab experiment headed … Read more The living lab experiment “Climate-Neutral Living in Berlin” takes stock

PIK on Climate Summit COP24 in Katowice

The UN climate summit COP24 in Katowice, Poland, closed; below PIK’s statement which I think is somewhat overoptimistic, remembering that the Paris agreement does not entail any compulsion toward change. COP24 President Michal Kurtyka’s celebration (cf. pix above) at the end of COP24  seems wildly out of proportion with what was actually achieved. On this issue, Johan Rockström, resilience scientist who as Director Designate is leading the Potsdam Institute for Climate Impact Research together … Read more PIK on Climate Summit COP24 in Katowice

Winter weather extremes in the US and Europe:

 Messing with giant airstreams in the stratosphere.  Press Release by the Potsdam Institute for Climate Impact Research 22/11/2018 Over Thanksgiving, arctic air masses are predicted to bring record-cold temperatures and frigid winds to the Northeast of the United States. Driver for such winter weather extremes is often the stratospheric polar vortex, a band of fast moving winds 30 kilometers above the ground. In winter, when the polar vortex is … Read more Winter weather extremes in the US and Europe:

Extreme Weather Likely To Become More Frequent

Press Release by the Potsdam Institute for Climate Impact Research 01/11/2018 Extreme weather will likely become more frequent due to stalling of giant waves in the atmosphere •    Computer simulations predict a strong increase of events in which the undulations of the jet stream in the atmosphere stop moving along. •    This can favor more frequent extreme weather events on the ground. •    Strong Arctic warming reduces the temperature … Read more Extreme Weather Likely To Become More Frequent

Planet at risk of heading towards irreversible “Hothouse Earth” state

Joint Press Release by the Stockholm Resilience Center, University of Copenhagen, Australian National University and the Potsdam Institute for Climate Impact Research 07/08/2018 Keeping global warming to within 1.5-2°C may be more difficult than previously assessed. An international team of scientists has published a study in Proceedings of the National Academy of Sciences (PNAS) showing that even if the carbon emission reductions called for in the Paris Agreement are … Read more Planet at risk of heading towards irreversible “Hothouse Earth” state

Stronger evidence for a weaker Atlantic overturning

Press release by the Potsdam Institute for Climate Impact Research 11/04/2018 The Atlantic overturning – one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards – is weaker today than any time before in more than 1000 years. Sea surface temperature data analysis provides new evidence that this major ocean circulation has slowed down by roughly 15 percent since the middle of the … Read more Stronger evidence for a weaker Atlantic overturning

WILLIAM T. VOLLMAN: WHAT IF THE LEFTWING HOAXERS ARE RIGHT?

VIA VIKING ON CLIMATE CHANGE DENIAL AND THE RESURGENCE OF CARBON-FUELED IDEOLOGY April 11, 2018  By William T. Vollmann In the time when I lived, it was still possible to meet Americans who disbelieved in global warming, although the ones I knew became shyer and rarer in about 2013. In 2016, they helped elect Donald Trump president, upon which their various carbon ideologies naturally came roaring back. “We sure need a … Read more WILLIAM T.

PIK: Reports of coal’s terminal decline are premature

Joint Press release by the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC)07/02/2018 While less new coal-fired power plants are now being built in China and India, the planned expansion in the use of coal in fast-growing emerging economies, such as Turkey, Indonesia and Vietnam, will in part cancel out the reduction. Only if the countries of the … Read more PIK: Reports of coal’s terminal decline are premature
