“Where else?” “It’s better than an oil refinery?!” Let me be clear: the energy transition needs to go hand in hand with preserving and restoring ecosystems, which are crucial for the functioning of the Earth system. And no, it’s not too late.

How do English oaks in Central Europe adapt to #drought? Let by #TetyanaNosenko we show in coop with the #ThünenInstitute that English oaks in Central Europe adapt to drought through local variation in water use efficiency (iWUE), with higher tolerance in drier regions & a link to spring phenology.

Heute ist der 22. März (Weltwassertag) und in fast ganz Deutschland sind die oberen Bodenschichten ausgetrocknet. Die Karten des UFZ Dürremonitors weisen sogar extreme Dürre in vielen Landesteilen aus. Das sollte man ernst nehmen. Anstatt über die Abschaffung des Umweltministeriums zu fabulieren.
