The below graph comes from a new global temperature trend study that compares different established datasets for land and ocean temperature. The results emphasize an often-overlooked phenomenon: geographically ‘skewed warming’ – leading to planet-wide precipitation shifts. Possible effects not only include drying of both the Amazon Basin and Africa’s Congo Basin, but also possible greening of the Sahel and the bordering southern Sahara, in North Africa.
But African biodiversity, that has to take a loss in drying zones elsewhere on the rapidly warming continent, may stand little chance setting foot in areas that are greening. That’s because these climatic changes are outpaced by rapid human population growth and agricultural expansion – we learn from another recent study, that compared climatic trends to land use trends.
