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

Coal phase-out: Announcing CO2-pricing triggers divestment

Press release by the Potsdam Institute for Climate Impact Research 29/01/2018 (embargo expired) Putting the Paris climate agreement into practice will trigger opposed reactions by investors on the one hand and fossil fuel owners on the other hand. It has been feared that the anticipation of strong CO2 reduction policies might – a ‘green paradox’ – drive up these emissions: before the regulations kick in, fossil fuel owners might … Read more Coal phase-out: Announcing CO2-pricing triggers divestment

River flood risks increase around the globe

Press release by the Potsdam Institute for Climate Impact Research 11/01/2018 (embargo expired) Adaptation now: River flood risks increase around the globe under future warming Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters. Scientists have now calculated the required increase in flood protection until the 2040s worldwide, breaking it down … Read more River flood risks increase around the globe

Counting the true costs of climate change

Press release by the Potsdam Institute for Climate Impact Research 10/11/2017 Counting the true costs of climate change: Impacts World Conference in Potsdam Destabilizing the climate can also destabilize societies. Global warming impacts cause substantial economic damages, hurts human health in many ways, influences the drivers of human migration, and it can jeopardize development for many of the world’s poor. To investigate effects in these four areas, close to … Read more Counting the true costs of climate change

PIK on Colder Winters & a Warmer Arctic

Press release by the Potsdam Institute for Climate Impact Research: Winter cold extremes linked to high-altitude polar vortex weakening 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 … Read more PIK on Colder Winters & a Warmer Arctic

From dry to wet: Rainfall might abruptly increase in Africa’s Sahel

Press release by the Potsdam Institute for Climate Impact Research 07/06/2017 Climate change could turn one of Africa’s driest regions into a very wet one by suddenly switching on a Monsoon circulation. For the first time, scientists find evidence in computer simulations for a possible abrupt change to heavy seasonal rainfall in the Sahel, a region that so far has been characterized by extreme dryness. They detect a self-amplifying … Read more From dry to wet: Rainfall might abruptly increase in Africa’s Sahel

Turning the Climate Tide by 2020

Press Release by the Potsdam Institute for Climate Impact Research 28/06/2017 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 … Read more Turning the Climate Tide by 2020

Cognitive Dissonance on Climate: The NY Times Op-Ed page has been terrible long before Bret Stephens
