habe soeben Artikel von @dean101 zum Wüstenwachstum / Desertification entdeckt, der Wind weht aus der Ecke des sog. mainstream . Dazu habe ich nur knapp geantwortet, weil sonst dickes Buch.

---to me this sounds like a scientific article. And these nice pictures from national geographic. When you visit berndsenf.de and desert-greening.com you will find out ( if you are scientifically minded), that it is 11.9% of the facts. Find out the rest by yourself, even if it takes several month. --
