IMPACT OF GLOBAL WARMING

in fact global warming is very real impact to human life on earth, for example, now the weather is unpredictable or taken into account, sometimes directly change cold heat, or heat when a sudden rain or extreme weather details.
Do you know the cause of this smua?
Do you know the volume of water on earth?
so, the volume of water on earth is 70% and this number is fixed, and none will be increased or diminished one bit, if it will change just a little big impact on our lives.
as I described above, the cause of extreme weather here one of them caused by the increased volume of water on earth, of course you can already guess what I maksutkan this.
yes, a large-scale melting of ice at the poles of the earth makes water volume increase, although there was no increase of 1% but its impact has been like this, what if all the polar ice caps melt?
certainly can not imagine there will be disaster like what on earth.
so for people on earth, love the earth we live before it's too late.
