“New Study Shows How Climate Change Is Already Reshaping The Earth”
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.
The new study, “Significant anthropogenic-induced changes of climate classes since 1950,” looks at multiple datasets of monthly temperature and precipitation over time. The main finding:
About 5.7% of the global total land area has shifted toward warmer and drier climate types from 1950–2010, and significant changes include expansion of arid and high-latitude continental climate zones, shrinkage in polar and midlatitude continental climates….
