For which the rest of the world thank you!

On the "Stabilisation of CO2 in the atmosphere"

"With unmitigated emissions, water resource stress due to climate change by 
the 2080s is predicted to worsen in many countries (for example, northern 
Africa, the Middle East and the Indian subcontinent) but improve in others 
(for example China and the USA). Emissions leading to stabilisation at 550 
ppm will reduce the number of people affected by water stress due to 
climate change from about three billion to about one billion. Stabilisation 
at 750 ppm has little effect on this total."
"By the 2080s, climate change and CO2 increases due to unmitigated 
emissions are estimated to increase cereal yields at high and 
mid-latitudes, such as Canada, China, Argentina and much of Europe. At the 
same time, cereal yields in Africa, the Middle East and, particularly, 
India are expected to decrease."

Did I ever say what I did for a living ;-)  Appologies for the lack of cob 
content, I won't do it again.
