Heating our climate damages our economies – study reveals greater costs than expected

08/19/2020 - Rising temperatures due to our greenhouse gas emissions can cause greater damages to our economies than previous research suggested, a new study shows. Scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute for Global Commons and Climate Change (MCC) took a closer look at what climate change does to regions at the sub-national level, such as US states, Chinese provinces or French départements, based on a first-of-its-kind dataset by MCC. If CO2 emissions from burning fossil fuels are not reduced rapidly, a global warming of 4°C until 2100 can make that regions lose almost 10% of economic output on average and more than 20% in the tropics.

An Economic Case for the UN Climate Targets: Early and strong climate action pays off

07/13/2020 - Climate action is not cheap – but climate damages aren’t, either. So what level of climate action is best, economically speaking? This question has puzzled economists for decades, and in particular since the 2018 Nobel Prize in Economics went to William Nordhaus, who found 3.5 degrees of warming by 2100 might be an economically desirable outcome. An international team of scientists led by the Potsdam Institute has now updated the computer simulation model used to come to this conclusion with latest data and insights from both climate science and economics. They found that limiting global warming to below 2 degrees strikes an economically optimal balance between future climate damages and today’s climate mitigation costs. This would require a price of CO2 of more than 100 US Dollar per ton.

Road access for all would be costly, but not so much for the climate

07/10/2020 - One of the UN’s Sustainable Development Goals aims to ensure access to transport infrastructure for all. A team of researchers led by the Potsdam Institute for Climate Impact Research (PIK) has now brought together various data sets to quantify the economic costs as well as climate implications of achieving this goal by providing universal road access. The result: While such road extension would weigh very heavily on individual countries’ budgets, on the global CO2 emissions budget it would not. To connect almost all the world’s population, the global road network would only need to be extended by 8 per cent, causing a total CO2 emissions of about 1.5 per cent of what we can emit while keeping global warming below 2 degree Celsius.

Direct CO2 pricing gives room for additional voluntary emissions reductions

06/30/2020- Most climate economist agree that it makes sense to put a price tag on the emission of the most important greenhouse gas carbon dioxide, CO2. The discussion primarily revolves around whether it would be better to achieve this through a tax or emissions trading. Arguments include the administrative effort involved, the signal effect for investors, and the political enforceability. A new study based on a scientifically controlled experiment now sheds light on another aspect that has barely been researched so far: the incentive effect of both options on actors who want to act morally beyond their economic interests. The study was conducted by the economists Axel Ockenfels, Peter Werner and Ottmar Edenhofer, and has now been published in the renowned journal Nature Sustainability.

Corona crisis fuels hate against Chinese on Twitter: Commentary

19/05/2020 - The COVID-19 pandemic has the world firmly in its grip with millions of confirmed cases worldwide and whole countries in full or partial lockdown. Despite calls for solidarity across borders and countless local support initiatives, various incidents prove that the corona outbreak has also given rise to a series of racist attacks against Chinese people and people with Asian looking features both on the streets and in social media networks. A team of researchers from the Potsdam Institute for Climate Impact Research has now investigated the use of discriminating language against Chinese people in the context of the COVID-19 pandemic on Twitter.

Caring for the future is key for cooperation to prevent climate collapse: study

20/05/2020 - How much decision-makers care about the future and not just the present is one key factor for whether or not they take action to stabilize our climate. Another one is how severe they assume the impacts of climate collapse to be. However, the number of actors is decisive – for instance the number of relevant countries, since efforts to reduce greenhouse gas emissions have to be international to add up to the amount needed to prevent a crisis. This is shown by a novel mathematical study. It finds a strong effect of diffusion of responsibility in scenarios with large numbers of actors. The study combines game theory and learning dynamics to explore which options for enhanced political cooperation should now urgently be studied empirically.

From artificial meat to fine-tuning photosynthesis: Food System Innovation – and how to get there

19/05/2020 - Food production has always shaped the lives of humans and the surface of the Earth. Be it plough or refrigerator, time and again innovations have transformed the ways we grow, process, and consume food over the last millennia. Today, with almost 40 per cent of all land on Earth used for food production, the food system massively impacts climate and environment – from nitrogen flows to water use, from biodiversity to greenhouse gas emissions. In a new study published in the journal NatureFOOD, an international team of researchers has now assessed and categorised key innovations with a potential to transform the food system, from artificial meat or seafood to biofortified crops or improved climate forecasts – and established what is most needed to make them succeed.

Delayed monsoon onset in Central India: early warning forecast

12/05/2020 - Summer Monsoon in Central India will likely begin between 18th and 26 of June, according to the new early forecast developed at the Potsdam Institute for Climate Impact Research (PIK). Led by PIK expert Elena Surovyatkina, the Monsoon forecast method showed to be successful already four years in a row. With global warming the monsoon is changing, breaking well-established “rules” of the phenomenon and thus becoming more unpredictable. A raising demand for a new understanding of the Indian Monsoon in order to be better prepared makes long-term forecasting even more important.
