Until now, it had been assumed that dams act as net carbon stores. Researchers from the Helmholtz Centre of Environmental Research (UFZ) together with Spanish scientists from the Catalan Institute for Water Research (ICRA) in Girona and the University of Barcelona showed that dams release twice as much carbon as they store. The study has been published in ....

Understanding the factors that control how fast glaciers move, break up and deposit chunks of ice (icebergs) into the fjords - and eventually the sea - is vital for predicting how the Greenland ice sheet will change under a warming climate and for predicting global rates of sea-level rise. A new study led by Stockholm University Assistant Professor Christian Stranne, shows that thick sea-ice outside the fjords can actually increase the sensitivity of Greenlandic fjords to warming. Stranne and a team of researchers from Sweden, Greenland, the Netherlands, the USA, and Canada report on expeditions to two distinct fjords in northern Greenland during the 2015 and 2019 summers. These fjords were practically inaccessible to researchers until quite recently because the sea-ice was too thick - they are some of the least-studied areas o ....
In 2018, Pompeu Fabra University launched its Planetary Wellbeing initiative, a long-term institutional strategy spurred by the United Nations Sustainable Development Goals (SDG) and based on the Planetary Health project promoted by the Rockefeller Foundation and The Lancet. ....

A significant rise in oxygen occurred about 2.43 billion years ago, marking the start of the Great Oxidation Episode a pivotal moment in Earth s history. An international research team including a UC Riverside scientist analyzed rocks from South Africa formed during this event. Findings, published this week in the journal ....
E-Mail Irvine, Calif. In 2019, the National Weather Service in Alaska reported spotting the first-known lightning strikes within 300 miles of the North Pole. Lightning strikes are almost unheard of above the Arctic Circle, but scientists led by researchers at the University of California, Irvine have published new research in the journal Nature Climate Change detailing how Arctic lightning strikes stand to increase by about 100 percent over northern lands by the end of the century as the climate continues warming. We projected how lightning in high-latitude boreal forests and Arctic tundra regions will change across North America and Eurasia, said Yang Chen, a research scientist in the UCI Department of Earth System Science who led the new work. The size of the lightning response surprised us because expected changes at mid-latitudes are much smaller. ....
