Die #Erderhitzung lässt sich auch durch Nullemissionen nicht zurückdrehen, nur die weitere Erhitzung stoppen.
Denn CO2 bleibt Jahrtausende in der Luft. Kipppunkte kommen näher.
Es wird kein Zurück geben.

#Lanzarote.
Übrigens nimmt die Wasseraufnahmefähigkeit von Luft Exponenziell mit der Temperatur zu, entsprechend auch die Extremniederschläge. Klimaforscher warnen seit Jahrzehnten davor. Das wird weiter immer schlimmer werden, bis wir Klimaneutralität erreicht haben.

In #Lanzarote, as a result of precipitation in several places, more than 70 liters of water fell per square meter, which led to more than 300 incidents.Houses, garages, streets, roads were #flooded. A state of #emergency was declared.@victorhugopi

It is just magical to spend time looking closely at sphagnum mosses, the bog builders. Holding up to 20 times their own weight in water, without them, we would have no bogs. So incredibly beautiful up close @CCWPeatlands @ipspeatlands @forum_wetlands – at Offaly, Ireland

Busy week for the @DTECT_IE team!
📌 visited one of our sites in Co Offaly
📌 started dipwell installations for #watertable measurements
📌 processed #drone #LiDAR data for drain mapping
Really exciting as we collect more data in the coming months!
