The role of barren surface for the greenhouse effect

The role of barren surface for the greenhouse effect

An sentence from Walter Jehne, which I really found stunning:

“Irrespectiable how many greenhouse gas molecules are in the air, the thing that determines the GHG effect is the amount of reradiation coming from the earth. Because we have bared the soil, this soil will heat up much much more so than the soil protected with green vegetation. … We have created 5 billion hectares of man made desert and waste land.”

Think about the effect what the loss of 50% of (natural) forests, the creation of millions and millions of square kilometres of bare soil, of beton and asphalt, and the degenerated land has on the altered ratio of sensible heat to latent energy!
