SPECIAL: Turning the Climate Tide by 2020

Photo Turning the Climate Tide by 2020The 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. Read more ...

Better farm water management can help to achieve UN Sustainable Development Goals

Better farm water management can help to achieve UN Sustainable Development Goals

07/20/2017 - Water use for food production today largely occurs on the expense of ecosystems. About 40 percent of the water used for irrigation are unsustainable withdrawals that violate so-called environmental flows of rivers, a new study shows for the first time. If these volumes were to be re-allocated to the ecosystems, crop yields would drop by at least 10% on half of all irrigated land, especially in Central and South Asia. This points to a tradeoff between water and food UN Sustainable Development Goals. However, improvement of irrigation practices can sustainably compensate for such losses at global scale. More integrated strategies, including rainwater management could even achieve a 10 percent net gain of production.

AGU prize for climate communication awarded to Stefan Rahmstorf

AGU prize for climate communication awarded to Stefan Rahmstorf

07/20/2017 - The World's largest organisation of Earth scientists will honors Stefan Rahmstorf with its Climate Communication Prize. The American Geophysical Union (AGU) gives this award for outstanding promotion of scientific literacy, clarity of message and efforts to foster understanding of science-based values as they relate to the implications of global warming. The physicist and oceanographer Rahmstorf, co-chair of Earth System Analysis at the Potsdam-Institute for Climate Impact Research (PIK), Germany, is the first scientist outside the US to receive the renowned prize.

Unabated climate change would reverse the development gains in Asia: report

Unabated climate change would reverse the development gains in Asia: report

14/07/2017 - Unabated climate change would bring devastating consequences to countries in Asia and the Pacific, which could severely affect their future growth, reverse current development gains, and degrade quality of life, according to a report produced by the Asian Development Bank (ADB) and the Potsdam Institute for Climate Impact Research (PIK).

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

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

06/07/2017 - 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 mechanism which might kick-in beyond 1.5-2 degrees Celsius of global warming – which happens to be the limit for global temperature rise set in the Paris Climate Agreement. Although crossing this new tipping point is potentially beneficial, the change could be so big, it would be a major adaptation challenge for an already troubled region.

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.

Why Climate Policy matters for the G20 finance ministers’ agenda

Why Climate Policy matters for the G20 finance ministers’ agenda

06/30/2017 - In order to stay below the 2 °C guardrail set in the Paris Agreement, climate policy should be integrated with the G20 finance ministers’ agenda. Finance ministers should consider the merits of carbon pricing for sound fiscal policy and thereby stimulate investments in carbon-free infrastructure. “It is rational for G20 finance ministers to embrace climate policy, even if climate change is not their primary concern,” writes a team of authors led by the Mercator Research Institute on Global Commons and Climate Change (MCC) in an article published in the new issue of the journal Nature Climate Change. In their article “Aligning climate policy with finance ministers’ G20 agenda”, Ottmar Edenhofer, Chief Economist at the Potsdam Institute for Climate Impact Research (PIK) and Director of MCC, together with MCC Secretary General Brigitte Knopf and colleagues from other institutions argue that investments in fossil fuels have become more risky in the post-Paris world.
