Climate of the future?

Climate of the future? Here we see some of the (probable) future costs of climate change.

The hydrological cycle - evaporation / precipitation of water - speeds up due to a warmer atmosphere: more heat --> more evaporation and more water vapor in the air --> extreme precipitation events and flooding.

However, the situation in Ontario this year is a bit particular: a "perfect storm" says Dave Phillips of Environment Canada. Global Warming alters jet stream patterns which, in turn, can freeze artic air circulation patterns resulting in COLDER winter weather. If more snow falls, as it did this year, the conditions are set for flooding when those globally warmed spring days finally hit..

The flooding in parts of Ontario is "historic". Worst 1n 137 years, since the beginning of weather records..
