Limiting global warming to 1.5°C would save billions of people from dangerously hot climate
05/23/2023 - If climate change continues as it has so far, more than one-fifth of the global population could be exposed to dangerously hot temperatures by the end of the century, according to a new study involving the Potsdam Institute for Climate Impact Research (PIK). According to the study, the countries of the global South in particular will be affected by hotter temperature ranges.

Effective capital markets are needed to protect the climate
05/22/2023 - A new study investigates the role of effective capital markets for climate protection and the energy transition. Banks collect savings and make them available as loans and the greater the difference between savings and loan interest rates, the more it costs to invest. This affects, for example, investments in fossil-free steel plants, power generation, or heating systems. The analysis by the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC) has now been published in the renowned Journal of the Association of Environmental and Resource Economists (JAERE).

Large-scale nature conservation efforts alone will not preserve benefits for our societies
05/16/2023 - The enlargement of protected areas and carbon price incentives for reforestation alone will not stop biodiversity decline and the ongoing loss of critical ecosystem functions, if they are not accompanied by measures that also target managed landscapes. A new study published in Nature Communications, led by the Potsdam Institute for Climate Impact Research (PIK), shows that even in scenarios with a high demand for land it is possible to maintain biodiversity-friendly landscapes, which also provide critical services such as pollination and healthy soils. The research demonstrates that land use is not a zero-sum game but that it matters where farmland is located in order to promote landscape diversity. With the right incentives, farmed landscapes could be managed in a way that enhances the numerous benefits nature offers to society and that support the biodiversity conservation targets of protected areas.

Greenland’s Ice Sheet might be close to first tipping point
04/05/2023 - The Greenland Ice Sheet is likely to be halfway towards a tipping point whose crossing would imply extensive further melting, a new study finds. While humanity has emitted ca. 500 gigatons of carbon so far, with about 1000 gigatons of carbon much of the massive ice sheet will melt irreversibly, a team of scientists shows.

Water has to become a common good – two new reports show
03/22/2023 - Water overuse and a failure to recognize that countries are interdependent when it comes to the global water cycle has put the world on a path to a potential 40% freshwater supply shortfall by the end of the decade. Water therefore has to be treated as a global common good. This is stated in a report by the Global Commission on the Economics of Water (GCEW) and also in a Nature Commentary – both led by PIK director Johan Rockström and released in the context of the UN Water Conference in New York, the first such meeting in 50 years.

Less predictable rainfall important for Maya decline
03/17/2023 - Reduced predictability of seasonal rainfall might have played an important role in the disintegration of Classic Maya societies about 1100 years ago. That is the result of a new study of the Potsdam Institute for Climate Impact Research (PIK) and Potsdam University. The research team studied variations in stable isotope signatures from a stalagmite that was collected in a cave near Uxbenka/Belize, an important archaeological site in the former heartland of the Maya. The carbon and oxygen isotope ratios are sensitive recorders of local and regional rainfall dynamics.

Tackling climate threats together: Munich Security Conference and Potsdam Institute for Climate Impact Research cooperate
02/17/2023 - The Munich Security Conference (MSC) and the Potsdam Institute for Climate Impact Research (PIK) are joining forces to tackle threats arising from global heating. Greenhouse gas emissions from coal and oil reached record levels last year, increasing extreme weather events and yield failure risks that can fuel smoldering conflicts in poor countries and contribute to destabilizing societies. To help limit these risks, the leaders of MSC and PIK as champions in their respective fields of expertise now signed a cooperation agreement.

Earlier, higher, smaller: Climate change alters glacial lake outburst floods
02/16/2023 - Due to global warming, flood-like water outbursts from ice-dammed glacial lakes worldwide happen earlier in the year and originate from higher areas. This is shown on the basis of observation data since 1900 by a new study with the participation of the Potsdam Institute for Climate Impact Research (PIK), which is published in the scientific journal Nature. At the same time, however, these so-called outbursts are also becoming smaller.

Coal exit can happen only with stronger policies – and with China
02/06/2023 - Current climate policies including efforts like the Powering Past Coal Alliance will not add up to a global coal exit, a new study shows. Countries phasing coal out of the electricity sector need to broaden their policy strategy, or else they risk pushing the excess coal supply into other industries at home, like steel production. The scientists find that China has an opportunity to dominate the renewable energy technology market if it begins phasing down coal immediately. Otherwise, it could dangerously delay the renewable energy breakthrough worldwide.

El Niño phenomenon: 2024 could be warmest year ever
02/03/2023 – With a likelihood of almost 90% the weather phenomenon "El Niño" will occur again in the Pacific region as early as this autumn. This may be accompanied by numerous extreme weather events, such as heavy rain in Peru and drought in Australia and Indonesia. As El Niño also increases global temperatures in the short term, there is a possibility that 2024 could be the warmest year since weather records began. This is what scientists from the Potsdam Institute for Climate Impact Research (PIK), Justus Liebig University Giessen and two Beijing universities report in a recent analysis.

Berlin could produce much of its vegetables locally
01/27/2023 - Berlin could produce a surprisingly large proportion of its vegetable requirements itself if unused areas were used for this purpose, such as flat roofs, allotments, cemetery areas that are no longer in use, or even supermarket parking lots. Researchers have now calculated this. However, the use of this land is tied to many preconditions.

Amazon heat drives Tibet temperatures: climate tipping elements connected half around the globe
01/26/2023 - While the Amazon rainforest and the Tibetan Plateau sit on different sides of the globe, scientists now discovered that changes in the South American ecosystem can trigger changes in the vicinity of the Himalayas. Both are tipping elements, hence large-scale elements of the planetary machinery that are sensitive to global warming and may shift abruptly and often irreversibly from one state to another at specific thresholds. A new study applies the theory of complex networks to these elements and finds surprising – and worrying – long-distance linkages.

Stuck – climate change makes people too poor to migrate
01/23/2023 - Climate change increases migration worldwide. Over the past 30 years, however, this effect has been considerably reduced as climate change weakens economic growth in the countries of the Global South. This is the research result of a team from the Potsdam Institute for Climate Impact Research comparing the observed migration flows to a scenario without the effects of climate change.
