COP29: PIK and KfW launch financing concept for carbon removals at world climate summit
11/11/2024 - Since the reduction of CO2 emissions is too slow to limit global heating to 1.5°C, a great deal of CO2 must be removed from the atmosphere. Depending on the scenario, this will cost up to 2 percent of annual global economic output in 2050. This effort is economically imperative because the climate damage per tonne of CO2 is many times higher. However, this would overburden state budgets, so a financial architecture is needed to mobilise private capital. The Potsdam Institute for Climate Impact Research (PIK) and KfW, one of the world’s leading promotional banks, are now making a joint proposal at the World Climate Summit.

Green growth: 30 percent of regions worldwide achieve economic growth while reducing carbon emissions
10/29/2024 - More and more regions around the globe combine economic growth with reducing carbon emissions, researchers from the Potsdam Institute for Climate Impact Research found. Their new study highlights the vital role of national climate actions in decoupling economic growth from CO2 emissions. The analysis of data from 1,500 regions over the past 30 years showed that 30 percent have managed to lower their carbon emissions while continuing to thrive economically. While this accelerating trend marks significant progress towards achieving the Paris Climate Agreement, the authors caution that the current pace of decoupling is insufficient to meet the global climate target of net-zero carbon emissions by 2050.

New attribution studies: Increasing effects of global warming on fire dynamics and public health
10/21/2024 - Climate change is increasingly influencing fire behavior worldwide and intensifying fire smoke, endangering public health from air pollution caused by fires. These are the results of two new climate change impact attribution studies, both published in Nature Climate Change, with involvement of the Potsdam Institute for Climate Impact Research PIK. The first study finds 15.8 percent higher global burned areas over the period 2003 to 2019 due to climate change, intensifying fire activity especially in Australia, South America, Western North America and Siberia. These increasing fire dynamics offset the decrease in burned area due to land-use changes and increasing population density. Building on this, the second study examines how climate change is linked to a global increase in deaths from fire-related air pollution. Climate change increased these deaths from 669 annually in the 1960s to over 12,500 in the 2010s.

New report: Global water crisis threatens more than half of world food production
10/17/2024 - The global water cycle is increasingly out of balance – with consequences for the world economy and humanity. This is the core message of a report by the Global Commission on the Economics of Water (GCEW), including Johan Rockström, Director of the Potsdam Institute for Climate Impact Research (PIK). The global water crisis could endanger more than half of global food production by 2050, the authors warn. This could result in a global median gross domestic product (GDP) decline of about eight percent. Lower-income countries may even face a decline in GDP of ten to fifteen percent. The Commission argues in favour of a new economics of water, which must redefine the way we value water. It also suggests five mission areas to counteract the existing water crisis.

Scientists caution no guarantees when it comes to overshooting 1.5°C
10/09/2024 - Even if it is possible to reverse the rise of global temperatures after a temporary “overshoot” of 1.5 degrees Celsius, some climate damages triggered at peak warming will be irreversible, a study published in Nature shows. The earlier net zero emissions can be accomplished, the lower peak warming will be, and the smaller the risks of irreversible impacts, an international team of scientists, including researchers from the Potsdam Institute for Climate Impact Research (PIK), finds. They analysed future scenarios in which 1.5°C of global warming are temporarily exceeded and temperatures are brought back down in the long run.

How a carbon central bank can turn Europe into a CO2 “eater”
09/17/2024 - The EU has decided to achieve climate neutrality by 2050. From then on, for every tonne of CO2 still emitted, one tonne would have to be taken out of the atmosphere. A European Carbon Central Bank could play a key role on the way there - and use market-based incentives to set the course for a net-negative emissions balance in the second half of the century, turning Europe into a CO2 “eater”, so to speak. Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), explained how this could work economically in the renowned “Thünen Lecture”.

What Works: Groundbreaking Evaluation of Climate Policy Measures Over Two Decades
08/23/2024 - An international research team has unveiled the first comprehensive global evaluation of 1,500 climate policy measures from 41 countries across six continents. Published in the prestigious journal Science, this unprecedented study provides a detailed impact analysis of the wide range of climate policy measures implemented over the last two decades. The findings reveal a sobering reality: many policy measures have failed to achieve the necessary scale of emission reductions. Only 63 cases of successful climate policies, leading to average emission reductions of 19 percent, were identified. The key characteristic of these successful cases is the inclusion of tax and price incentives in well-designed policy mixes.

Tipping risks from overshooting 1.5 °C can be minimised if warming is swiftly reversed
08/01/2024 - Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 °C of global warming after a period of overshoot. A new study published in Nature Communications indicates that this risk can be minimised if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers from the Potsdam Institute for Climate Impact Research (PIK), the International Institute for Applied Systems Analysis (IIASA) and other institutes write. They analysed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.

Up to 30 percent more time: Climate change makes it harder for women to collect water
06/21/2024 - By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study published in Nature Climate Change. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. A team of scientists from the Potsdam Institute for Climate Impact Research (PIK) estimates the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions. Worldwide, two billion people currently lack access to safe drinking water. The responsibility for collecting water typically falls on women and girls.
