Fire dynamics in the South American Chaco and their link to agriculture and drought
Nature Sustainability - Climate change, particularly intensifying droughts, is often blamed for wildfires across the Gran Chaco, a vast South American dry woodland. An analysis of over 30 years of...

In seinem letzten Interview als Bundestagsabgeordneter beschreibt Robert Habeck nochmal präzise, was die Union gerade tut: Sie spaltet das Land mit quatschigem Kulturkampf, um von den Problemen abzulenken. Lesenswert:
