Now global warming is going on. Has global rain fall increased corresponding to the warming? if not why?

Answer 1

Yes it has increased, not by a huge amount but by the amount predicted and enough to be measured.

Precipitation starts life as evapouration from the seas and oceans, the warmer it is the more evapouration takes place. The world has wamred in the last couple of hundred years but it's by less than 1 degree Celsius, whilst this does cause more evapouration it's not really that big a rise.

Some areas have witnessed increasing rainfall whilst at the same time, others have witnessed decreasing rainfall. The net result is a small overall increase.

-----------------

What on earth is the previous answerer going on about - "also kid, if you want to be as smart as me..."? How can someone resort to such disparaging remarkes immediately after demonstarting their own ineptitude and ignorance.

Volume of ice has no relevance to the amount of water it displaces - it's the mass that's important. Anything that floats, regardless as to what it is, displaces it's own mass. A large ship weighing 1000 tons and a small ship weighing 1000 tons both displace the same amount of water even though the volume of the two ships is different - ice is no different.

If Brandon really were as smart as he believes himself to be he'd know that floating ice, when it melts, has no effect on water level. Moreover, he'd also know that neither Antarctica or Greenland are floating and any meltwater runoff from the ice caps here is adding to the volume of water in the seas and oceans.

The Arctic Ice Cap is floating and any melting that occurs here has no effect on sea levels.

Answer 2

You may very well have a point about increased rainfall. For some time I have been thinking that what we are experiencing is Global Wetting and not just Global Warming.

Warming the planet up is not going to make the rain stop. It may actually make it rain more often.

Looking at the damp weather we've had here in London so far this May, I am convinced that we're having Global Wetting. London wetting anyway.

Edit: Chris sis above is wrong about the amount of water on planet Earth increasing. Water is either in its liquid form or frozen at the poles. If the polar ice melts, the volume of liquid water will indeed rise, but the overall total amount of water will not increase. More water vapour will be released into the atmosphere and it will rain more often, possibly.

Polar ice is not made up of just water, it contains a high percentage of air trapped inside it. When an iceberg melts, you can hear a loud creaking noise. This is cause by air being squeezed out of the ice.

Answer 3

This global warming is just a theory which the politicians have jumped on as an ideal excuse to increase tax and thus justify their unnecessarily high wages. Rainfall varies from year to year any way and the temperature also. I remember the long hot summers of the 70's and no one said global warming then. The reason that this idea is being pushed is that there are too many vested interests, Politicians, Scientists and Manufacturers with an axe to grind and profits to make for it to go away and the Green lobby just help them. However it is a fact that warm air will hold more water moisture and thus the precipitation will increase.

Answer 4

Of course, the Earth is an island.
Such water, water vapour whatever you call it is trapped by gravity and remains in one form or another.
During its existence the Earth has warmed up, cooled down, several times - and we are just at the end of a mini ice age.
The Poles are constantly on the move (the pole star is a different star to the one two thousand years ago)
The ice caps have also moved and the North cap has melted at earlier times.
It is impossible to say weather or not it rains more today than years ago.
Most of the hype is down to TV ratings and newspaper circulation, the trends that fit the current scaremongering are trumpeted those that do the opposite are quietly ignored.
One theory is that global warming leads to increased levels of high cloud that reflect the heat of the sun resulting in lower temperatures at ground level. There are many theories and thats what they are, mere guesses on someones part that hit the news and are presented as fact.

Answer 5

It hasn't changed. The heat has but not the rain. Also I am getting tired of people stating the level of water will rise. When Ice melts the volume it takes up actually decreases. The water level will drop, not rise (assuming that the caps melt). Also kid, if you want to be as smart as me, you'll have to start by not sounding like your middle school teacher or just doing your homework like a normal kid.

Answer 6

In the 90's the same global warming freaks were saying we were going to die from acid rain. What a pathetic group.

Answer 7

Rainfall pattern will not be same for all the globe. Some part like Northern Hemisphere, mid and high latitude will have increase in rainfall especially in winter and autumn months while tropics and sub tropics in both hemiphere will expereince decrease in rainfall.

Answer 8

Of course it has you haven't noticed that the polar ice caps are melting? With the melting of the polar ice caps the amount of water is rising on Earth. With that said places that wouldn't normally get water are being to get rain. And the same goes for the places that noramlly get excess amount a year are getting more and more as this on. So in summary with the polar ice caps melting there is going to be more rain.
