According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. AWI researchers have now, for the first time, tested the concept using a complex climate model and published their findings in the journal Earth’s Future. Their verdict is sobering: though the approach could potentially put off ice-free Arctic summers for a few more decades, beyond the Arctic the massive campaign wouldn’t produce...
Supported by the AWI researchers from the Charité set out to determine whether or not an Antarctic expedition produces changes to the structure and function of the human brain.
The good news: the rise in global CO2 emissions has slowed. The bad news: this year, global emissions rose once again. This can be seen in the latest calculations from the Global Carbon Project, which Judith Hauck from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) substantially contributed to preparing.
AWI Director Antje Boetius is honoured as female researcher of the year and awarded the “2019 Erna Hamburger Prize”.
Permafrost coasts make up about one third of the Earth’s total coastline. As a result of accelerated climate change, whole sections of coastline rapidly thaw, and erode into the Arctic Ocean. A new study published in the journal Geophysical Research Letters now shows that large amounts of carbon dioxide are potentially being produced along these eroding permafrost coastlines in the Arctic.
