Monday, October 12, 2015 - There is little doubt that some sort of climate change is occurring. The popular press mostly views climate change in a negative sense and projects pessimistic images of overgrazing, degradation,
sand storms, and sand-dunes "marching" south from the Sahara towards the sea.
Experts at Arizona State University have engaged in a study that ultimately showed that the West African Sahel, the strip south of the Sahara desert, has been "re-greening" ever since droughts in the 1970s and 80s. They maintain that increased rainfall caused by climate change has led to more carbon dioxide in the atmosphere, which has spurred more plant growth and community-led farming efforts. The region is turning around and experiencing a vast change from the drought and deaths that once plagued it.
Contrary to those who view climate change as only having catastrophic consequences, these University researchers suggest that some aspects of climate change can be beneficial and cite this report as one example of a 'positive impact' from global warming.
The report, published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS), was titled, "On re-greening and degradation in Sahelian watersheds."
