In another report which sceptics will call alarmist and Lord Nazh will call Climate Porn, despite the phenomenon undoubtedly occurring and being cashed in on by the authorities, this sort of thing was written:
Global warming will create at least 1 billion refugees by 2050 as water shortages and crop failures force people to leave their homes, sparking local wars over access to resources, Christian Aid agency has said.
The Intergovernmental Panel on Climate Change says that by 2080, up to 3.2 billion people — a third of the planet's population — will be short of water. Up to 600 million will be short of food and up to 7 million will face coastal flooding.
I'd concentrate more on the water crisis because that's the one I now believe will fall into governmental hands to use as leverage on the population. I don't mean overall water but drinkable water. Drinkable water will become like gold.
