Global Warming!!!! Fact or Rumers?????

GLOBAL WARMING

I am hearing this word since last few years. Almost 10 years and now i really want to know that is that such this is happening or just it is advertisement that we are going to die?
Well a fact is that when the earth is made it has just a crust and a core at that time the temperature of earth was too much high and during that time there was a cloud of gases which make thunders and rains for many years(this is not a joke but fact is that continuous a century it rains to make the earth coll) after that the time comes at that time whole world was under the ice (ICE AGE) and again there is some variation in the temperature but i think that is normal way to manage the thing it occur before but we do not realized but now civilized so we give it name as global warming!!!



i hear that some gases like carbon dioxide , Nitrogen Oxide and methane and almost going into the troposphere and get collected there and a effect called Green House effect keep the control of the temperature of the earth. the carbon dioxide is the gas that help to keep our temperature constant. the sun light have too much radiation that comes on earth but from the ozone layer the ultra violet rays are reflected so some of heat are decayed there and after that some heat comes with that light come on earth and the earth's surface reflect that light but this gas trap that energy and make the earth hot.
and we are increasing the carbon dioxide,nitrogen oxide and methane in some manner by driving vehicle or cutting the trees (Don't forget that they removes the CO2 from the atmosphere and add O2 ). Most of this this is occur due to incomplete combustion!
Now u want to know that what is global warming???
it is increment of temperature of the whole world by a degree!

There are two benefit of this global warming:

• The precipitation will be less now (Precipitation means rain of water or ice).
• The Sea level will be increase now.
  

Here are some thing told by National geographic :

• Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier.Polar bears and indigenous cultures are already suffering from the sea-ice loss.
• Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park, now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.
• Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise.
• An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.

you can't bealive that Cow 'emissions' more damaging to planet than CO₂ from cars (Want to understad ok hear that the cow )
