A global context for megadroughts in monsoon Asia during the past millennium

By Paul Homewood

This paper appeared in my inbox, for some reason! It is from 2010, but is still highly relevant, since it finds evidence of megadroughts in India, China and Vietnam during the 14th and 15thC, directly linked to the onset of the Little Ice Age.

The authors make it clear these megadroughts have no match in the current era:

These megadroughts are consistent with HH Lamb’s findings, that an expanding Arctic squeezes the tropical rain belts more tightly around the equator. In other words, while the tropics get wetter, the monsoon in India and elsewhere does not tend to go as far north.

This paper also provides yet more evidence that the Little Ice Age truly was a global phenomenon.
