Polar ice caps melting
The ice caps melting is a four-pronged danger.
First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise.

Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English – make it less salty. The desalinization of the gulf current will “screw up” ocean currents, which regulate temperatures. The stream shutdown or irregularity would cool the area around north-east America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area!
Third, temperature rises and changing landscapes in the artic circle will endanger several species of animals. Only the most adaptable will survive.
Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect sunlight, much of which is relected back into space, further cooling Earth. If the ice caps melt, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.
Warmer waters and more hurricanes
As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. We saw in this in 2004 and 2005.
Increased probability and intensity of droughts and heat waves
Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate Change, global warming will exacerbate the conditions and could lead to conflicts and war.
Spread of disease
As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.
Economic consequences
Most of the effects of anthropogenic global warming won’t be good. And these effects spell one thing for the countries of the world: economic consequences. Hurricanes cause billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.
hey every individual knows abt Global warmin and they r feelin it.... yet they dont take precautionary measures to save the EARTH..!! thats the big drawback which v face.... No one is ready to give their comforts to reduce global warming...!! every individual should tak action to stop it..!!!
ReplyDeleteHi Arachana,
ReplyDeleteYou are true. we are really becoming boiled frogs. We care only abt the massive disasters like an earthquake, tsunami , but we are bothered abt the "tree" which is being cut at the corner of our street. Even the nations arrange for rendezvous in sprawling lounges. Its ironical that very meeting organised to curb emissions eventually end up pollute the atmosphere by having air conditioned halls for a mere discussion on this fact. Its a pity that even great environmental analysts are invloved in such mammoth rendezvous. Hence the implementation of solutions for this problem has become a far fetched dream.
hey ...wat u say is correct aishu.....bt anyways it is too technical dear...inbetween all these technical stuff post somethin entertaining...so tat it will attract more viewers to ur blog...this is just a suggession......
