Climate change will have catastrophic effect on key rivers: study

[Barrett808]

Climate change will have a disastrous effect on the flow of rivers which provide water for most of Earth's cities, New Scientist says.
Rising levels of carbon dioxide pollution, caused by the unbridled burning of oil, coal and gas, will warm the troposphere, the lowest layer of the world's atmosphere, in addition to the land and seas, it says.

Warmer air temperatures will affect water vapour, cloud cover, solar radiation and ozone, which in turn will have an impact on evaporation and rainfall.

In a computer model that factors in these changes, Princeton University researchers found that precipitation over the next three centuries will increase, boosting the discharge of fresh water around the world by nearly 15 percent.

But the regions that will be benefit are those that are already abundant in water or are sparsely populated, such as the tropics, the far north of Canada and northern Russia.
