Canadian scientist Robert Sandford warns about how climate change will affect water cycles and why it will lead to more potential storms...
...warmer air can hold more moisture. Thus, as temperatures rise due to the increase in greenhouse gases in the atmosphere, the water vapour content of the atmosphere will increase, and this will set off a 'water vapour feedback', where the increase in water vapour ? one of the strongest greenhouse gases ? will increase the warming already experienced due to the other greenhouse gases, which will, in turn, increase the amount of water vapour in the atmosphere, and so on. All this extra water vapour in the atmosphere will be at the expense of water locked up in the snow pack, and in the ground, and this is expected to disrupt the water cycle.
"What we're seeing as a consequence of that is more extreme weather events," said Sandford. "In 2005, for example, there was a two-hour storm in Toronto that caused $700 million worth of damage, mostly water-related and transportation infrastructure."
Sandford also talked about "massive water vapour rivers" moving water around the world to places where it doesn't usually go, causing heavy rains in California, and flooding in Australia and Pakistan.
