When the flames are out, danger continues: Cascading effects of wildfires
03/15/2021 - After extreme weather events like droughts and wildfires, it often only takes small additional natural hazards like rainfall to trigger further disastrous cascading hazards, a new study finds. A team of scientists based in Potsdam and Berlin analyzed the devastating forest fires in Australia from 2019 to 2020, which - in their intensity and severity – are likely linked to human-made global warming. The researchers reveal that the following much needed rain caused severe further damage, gravely impacting both people and nature.

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.

Looking beyond the farm gate: New IPCC Special Report on Land Use and Climate Change
08/08/2019 – Almost three quarters of habitable land on earth are under human use – resulting in substantial impacts on our climate, a new report of the Intergovernmental Panel on Climate Change (IPCC) shows. Today, almost a quarter of human-made greenhouse gas emissions arise from agriculture, forestry and other land use. The latest IPCC Special Report investigates the current situation, possible future scenarios and potential solutions on how we can use land to feed ourselves, fuel economic growth and limit climate change risks. Two Potsdam scientists figure as lead authors of the chapter on food security and on the relations between land and climate.

Nice sunny days can grow into heat waves – and wildfires: summer weather is stalling
20/08/2018 - Be it heavy downpours or super-hot spells, summer weather becomes more persistent in North America, Europe and parts of Asia. When those conditions stall for several days or weeks, they can turn into extremes: heatwaves resulting in droughts, health risks and wildfires; or relentless rainfall resulting in floods. A team of scientists now presents the first comprehensive review of research on summer weather stalling focusing on the influence of the disproportionally strong warming of the Arctic as caused by greenhouse-gas emissions from burning fossil fuels. Evidence is mounting, they show, that we likely meddle with circulation patterns high up in the sky. These are affecting, in turn, regional and local weather patterns – with sometimes disastrous effects on the ground. This has been the case with the 2016 wildfire in Canada, another team of scientists show in a second study.

Spacefood for cows: Industrial microbes could feed cattle, pigs and chicken with less damage to the environment
06/20/2018 - Deforestation, greenhouse gas emissions, biodiversity loss, nitrogen pollution – today’s agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.

Consumption, climate change and agriculture
16/12/2016 - The holiday season is in full swing and many enjoy the opportunity to feast – or to make new year resolutions for a healthier diet. What we eat is more than a private decision – the agriculture and land use sector is one of the central players in ambitious climate change mitigation efforts. Yet, mitigation policies in agriculture may conflict with food security. A team of scientists from the Potsdam Institute for Climate Impact Research analyzed the impacts on food prices under mitigation policies – targeting either incentives for producers or consumer preferences. They show that policy instruments to mitigate climate change with an educational approach to change food preferences can avoid unwanted impacts of climate change mitigation measures on food security.

Reducing food waste could help mitigate climate change
04/07/2016 - About a tenth of overall global greenhouse-gas emissions from agriculture could be traced back to food waste by mid-century, a new study shows. A team from the Potsdam Institute for Climate Impact Research for the first time provides comprehensive food loss projections for countries around the world while also calculating the associated emissions. Currently, one third of global food production never finds its way onto our plates. This share will increase drastically, if emerging countries like China and India adopt Western nutrition lifestyles, the analyses shows. Reducing food waste would offer the chance to ensure food security, which is well known. Yet at the same time it could help mitigate dangerous climate change.

Extreme events forcing global warming? Climate extremes and the carbon cycle
08/15/2013 – Extreme events like heat waves, droughts, heavy rain might not only occur more frequently due to climate change. They could also force global warming if terrestrial ecosystems release CO2 as a result of those extremes. An international team of researchers now analyzed the impacts of extremes on forests, bogs, grass landscapes and arable areas througout the world, among them scientists from the Potsdam Institute for Climate Impact Research (PIK). Terrestrial ecosystems absorb about 11 billion tons less carbon dioxide every year as the result of the extreme climate events than they could if the events did not occur, the researchers write in the renowned journal Nature. This is equivalent to approximately a third of global CO2 emissions per year.
