Summer storm weakening leads to more persistent heat extremes

Storm activity in large parts of the US, Europe and Russia significantly calmed down during summers over the past decades, but this is no good news. The weakening of strong winds associated with the jetstream and weather ...

Clean technology can partially make up for weak CO2 pricing

Clean technology support can to some extent make up for weak CO2 pricing and hence help keep the two degrees target within reach, a new study shows. Even if the world climate summit in Paris later this year is successful ...

Antarctica could raise sea level faster than previously thought

Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists provide a comprehensive estimate ...

Trapped atmospheric waves triggered more weather extremes

Weather extremes in the summer—such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012—have reached an exceptional number in the last ten years. Man-made global warming can ...

Capturing CO2 emissions needed to meet climate targets

Technologies that are discussed controversially today may be needed to keep the future risks and costs of climate change in check. Combining the production of energy from fossil fuels and biomass with capturing and storing ...

Connecting dead ends increases power grid stability

Climate change mitigation strategies such as the German Energiewende require linking vast numbers of new power generation facilities to the grid. As the input from many renewable sources is rather volatile, depending on how ...

From chaos to order: How ants optimize food search

Ants are capable of complex problem-solving strategies that could be widely applied as optimization techniques. An individual ant searching for food walks in random ways, biologists found. Yet the collective foraging behaviour ...

Dangerous nitrogen pollution could be halved

The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution ...
