African Desertification

“Comparison of archival and recent photographs shows a marked increase in Namib Desert vegetation over the past 90 years of CO? increase, while regional climate models predict increased aridification with climate change.”

    I am not a climate scientist but I have my own theory about the CO2- vegetation- cloud and temperature chain.

    I think that CO2 is part of one of the feedback chains to regulate earth temperature:

    Temperature increases cause an increase of CO2 in the atmosphere.
    Increasing CO2 causes greening
    Greening increases water vapour release in the atmosphere which cools down the atmosphere by increasing the albedo.
    The contrary happens when the earth cools down: CO2 decreases, the earth reduces greening and thus albedo reduces which leads to an increase in temperature.

    So this may be a oversimplified and somehow naive theory, but nature is full of such self regulating systems which keep a dynamic equilibrium with oscillations around an average value.
    Without such self regulation life would not be possible.

    Back when I was really ignorant about this stuff, “desertification” was the juicy hook for me. I will never forget the photos of dried-up, cracked lake beds and the articles filled with dire predictions that went along with them. It was frightening.

    Then, it began to rain. And the temperatures didn’t rise. Predictions began failing – dates came and went. The ‘desertification’ articles evaporated. 😉 The scaremongers moved on to other frightening predictions, never giving a mea culpa about global warming predictions.

    They did the same thing with the poley bears – the dire articles, which had been myriad, slowly disappeared. And, the same with hurricane predictions, which were all the rage in the first decade of this century.

    Then, the buzz phrase and headlines morphed from global warming to climate change.

    They lost this one-time believer in their snake oil. Forever.
