A landmark study in the journal Nature documents an expansion of the world’s dry and semi-arid climate regions since 1950 — and attributes it to human-caused global warming.
This expansion of the world’s dry zones is a basic prediction of climate science. The fact it is so broadly observable now means we must take seriously the current projections of widespread global Dust-Bowlification in the coming decades on our current CO2 emissions pathway — including the U.S.’s own breadbasket.
The new study, “Significant anthropogenic-induced changes of climate classes since 1950,” looks at multiple datasets of monthly temperature and precipitation over time.
