Yes ... some parts of AGW are fairly clear-cut ... especially the clear-cutting of forestlands ... ha ha ... that's pretty clear-cut evidence IMEIO ... and I think we can all agree man-kind could be better stewards of the land ...
From
Wikipedia:
"The most widely accepted of [the many many definitions of desertification] was that of the
Princeton University Dictionary which defined it as "the process of fertile land
transforming into desert typically as a result of
deforestation,
drought or improper/inappropriate agriculture". This definition clearly demonstrated the interconnectedness [sic] of desertification and human activities, in particular land use and land management practices."
That's different from the magical forces of carbon dioxide to warm the atmosphere by more than a degree or two ... which of course plants also enjoy ... especially human food crops most always do better in warmer climates ... visit California's Imperial Valley in December if you don't believe me ...
