CBS reported this was MAN MADE CLIMATE CHANGE causing all of this. Wackos
climate changers are science deniers
Recent mega droughts in North America go back to 900AD to 1300AD. The Sierra and Northwest Basin drought of 400 years was followed by the Great Basin/Mississippi Valley 500 year drought, catastrophic for the corn cultures and hunter/gatherers as well as buffalo and other game, at the same time England was enduring a little ice age. Same for Central and South America. The Mayans didn’t build irrigation canals because of plentiful rainfall but because every drop of water was valuable.
Also, contrary to popular propaganda, “climate change” has never been a reason for people to quit their country. Weather does cause people to move away or nearer to fresh water, but within their own country; violence and corruption have been the primary historical drivers drivers of complete exodus.
