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.

Smart nitrogen management can strongly reduce pollution
01/06/2023 - To increase food and feed supply, agriculture has used more and more industrial nitrogen fertilizers and manure. However, over half of these nitrogen inputs to croplands are currently lost to the environment, contributing to air pollution and its related diseases, water eutrophication, soil acidification, climate change, and biodiversity loss. Nitrogen pollution has become a global challenge and next crisis. An international team of researchers explored cost-effective nitrogen mitigation strategies for global croplands in a new study, now published in Nature.

Climate risk insurance can effectively mitigate economic losses
01/04/2023 - Global warming is expected to lead to an accumulation of particularly intense hurricanes in the United States. This may substantially increase the economic losses caused by these storms. Better insurance could effectively mitigate the climate change-induced increase in economic losses. This is shown in a new study by the Potsdam Institute for Climate Impact Research examining the effectiveness of climate risk insurance in the US.

Overshooting climate targets could significantly increase risk for tipping cascades
12/22/2022 - Temporarily overshooting the climate targets of 1.5-2 degrees Celsius could increase the tipping risk of several Earth system elements by more than 70 percent compared to keeping global warming in line with the United Nations Paris Agreement range, a new risk analysis study by an international team of researchers shows. This tipping risk increases even if in the longer term the global temperature would stabilize within the Paris range. Avoiding an overshoot would hence limit the risks, the researchers conclude.

Carbon dioxide removal should receive additional financial support
12/20/2022 - Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on carbon emissions to incentivize their reduction. In a first-of-its-kind study, researchers analyze policies for removing carbon dioxide from the atmosphere and storing it underground or in products. The suggested different pricing is not due to technological challenges, but linked to an economic effect called leakage.

Global inequality prevents effective climate protection in the land sector
12/08/2022 - Land-based climate protection in line with the Paris Agreement can only succeed by overcoming global inequality, according to a new study by the Potsdam Institute for Climate Impact Research (PIK). This requires a shift towards healthier nutrition, less food waste and lower population growth. It is also necessary to put a price on greenhouse gas emissions from agriculture and forestry at the global level.

COP27 world climate summit: “Results are not good enough”
11/22/2022 – A COP failure was avoided, but it was only a very moderate success for the climate. While 1.5 as a global goal is still there on paper, COP27 does not offer a concrete plan on how to achieve that. These are, in a nutshell, the assessments by PIK Directors Ottmar Edenhofer and Johan Rockström just after the 27th edition of the world climate summit COP concluded on Sunday in Sharm el-Sheikh, Egypt. Positive outcomes of the summit include a first-of-its-kind set up of a ‘loss and damage fund’ that shall aim at compensating climate impacts for developing countries.

Astronomical cycles changed the climate 200 million years ago
10/11/2022 - The celestial bodies of the solar system also influence the Earth's climate cycles. The question of how this astronomical "heartbeat" changed the Earth's climate in an early warm period was investigated by an international team of geo- and climate researchers. Using simulations and data from drill cores, they were able to prove that astronomical cycles - in addition to shifts in continental plates and fluctuating CO2 levels in the atmosphere - drove climate changes around 200 million years ago. These new data from past warm climate phases with higher greenhouse gas concentrations can also be interesting for improved forecasts. The results were published in the scientific journal PNAS.

Fossil fuels threaten health and life: Experts call for massive acceleration of the energy transition
11/03/2022 - The consequences of climate change are one of the greatest health risks of our time. This was stated by the Federal Minister of Health and the President of the German Medical Association together with PIK Director Johan Rockström and the organisation German Climate Change and Health Alliance (KLUG), that had invited to the Federal Press Conference. Together they advocate accelerating the energy transition in Germany and minimising greenhouse gas emissions. The background to this is a recently published report by the leading medical journal The Lancet, which highlights dependence on fossil fuels as a threat to health and life. The experts highlighted the fundamental importance of the report for Germany and what has to follow from it politically and in the German healthcare sector.

Economic losses from hurricanes become too big to be offset by the US if warming continues
10/17/2022 - Hurricane damages can increase due to increasing global temperatures, caused by greenhouse gas emissions from fossil fuels. Computer simulations of regional economic sectors and supply chains in the US now show that the resulting economic losses can at some point not be nationally offset under unabated warming. If too many factories and the like are hit by the hurricane and stop working, other countries will have to step in to provide the supply of goods, according to the scientists who did the study. The hurricane impacts under global warming will thus give the US an economic disadvantage, the warmer the more.
