Rivers and streams emit much more CO2 at night than during the day Research EPFL EPFL scientists have found that streams and rivers – or “running waters” – emit on average four times more CO2 at night than during the day. That matters because most estimates of global CO2 emissions are made using measurements taken during the day, thereby introducing a potential bias into the calculation of the global carbon cycle. Scientists unlock the secrets of glacier-fed streams Research EPFL EPFL scientists have been busy over the past two years collecting and analyzing samples from streams fed by the world’s biggest glaciers. We spoke with some of the researchers on the project about their globe-trotting adventure. Find out more about it on our brand new longreads website. Climate change significantly increases population displacement risk Research ETH Zurich The risk of people being forced from their homes by flooding increases by half for each additional degree of global warming, as an international research team led by the Weather and Climate Risks Group at ETH Zurich demonstrate. Exceptional summer droughts in Europe since 2015 Research WSL An international team studied the chemical fingerprints in European oak trees to reconstruct summer climate over 2110 years. They found that after a long-term drying trend, drought conditions since 2015 suddenly intensified, beyond anything in the past two thousand years. Climate change influences river flow Research ETH Zurich River flow has changed significantly worldwide in recent decades. An international research team led by ETH Zurich has now demonstrated that it is climate change, rather than water and land management, that plays a crucial role at a global level. A call for charging points at home Politics ETH Zurich For Switzerland to become climate neutral, there’s no way around electric mobility. But to get e-cars going, the public must push for charging stations where people live, argues Anthony Patt. Previous 23 24 25 26 27 28 29 30 Next Page 29 of 30
