Global warming as everyone knows causes unprecedented increase in temperature.But many dont realize that it also causes an increased amount of evaporation and uneven precipitation.Along with the evaporation from the water bodies it also takes up the moisture from the landmasses which leads to land becoming dry and parched,useless for cultivation.We saw that the in recent years there was a massive flooding in mumbai while andhra pradesh had it's worst heat wave.This year(2008) also saw mumbai getting rains earlier than expected getting flooded a bit.
Japan in 2005 also recieved the maximum no: of typhoons ever - 10.USA also had its share with largest no: of hurricanes ever recorded.- 7000 odd
Global warming not only increases precipitation but also redistributes it.2-3 yrs back in china while one province was getting terribly flooded , a neighbouring province suffered a worst ever drought which cracked the earth like nothing before.So did we observe these before?and even if we observed it we would dismiss as something occasionally off the track.Lets face it,its not occasional,its gonna be permanent unless we do something now.
In the Africa , we can see very very bad tragedies due to temperature rise.Sudan , Niger , Darfur are the nations right on the tropical belt which have suffered most.These nations have experienced worst ever drought ever recorded. One reason among many is the drying up of lake Chad which was very large and now just look at it.
So you see what a difference in just 40 yrs....................Think my frnds ..think..time to act or face the consequences.
