What are the effects of global warming on the water cycle?

Answer 1

Global warming won't have a large impact on the totalwater cycle per se, only on local water cycles. Some places will become drier than usual, whereas others are expected to become wetter than usual. In general, the same amount of precipitation is expected, just that its distribution will be significantly altered.

Ground water levels tend to be dropping due to pumping for irrigation rather than lack of rain fall, though drought can be a contributing factor. However, glacial ice melt provides water for many areas around the world. The acceleration of ice melt is expected to result in short term flooding and long term drought.

• water cycle is completely altered ground water level is going down
• More evaporation
• Less precipitation
• the water cycle might stop if global warming continues

A part of the Global water cycle is Snow into Ice and Ice into Glaciers. Glaciers are disappearing.

Those who distrust this are like the passengers in Doctor David Suzuki's Car - Humankind racing to Collision with a brick wall; one said that they are just wondering how hard the bricks are - yet really we are just only fighting over which seats we will have.

Answer 2

It do speed up water cycle since accumulation of heat promote evaporation to cloud then release heat to space and condense to rainfall. The water cycle act as heat pump conveying heat away faster and dissolve CO2 down along its' path to the sea (Carbon sink).

Water cycle is the reason why the increase of CO2 level and increase of global warming effect seem slower than what is predict by greenhouse model.

Speed up of water cycle might contribute to occurrence of storm to some extend.

Answer 3

More evaporation, less precipitation, and ground water level is going down.

Answer 4

1. There is a higher chance of heavy rain

2. There is a higher risk of severe drought

3. There is a higher chance of stronger storms (up to three times as strong)

Answer 5

to become more extreme.
