Answer 3

People are watching the earth move through it's cycles.  Right now, ice is melting.  The oceans will rise, and Greenland will be green again.  Then it gets cold over time and cycles back to what we're used to.

Taking a 100 years sample of history and saying the earth is doomed is like taking a 30 minute sample of a day in the evening and saying the Sun will be gone forever.

Answer 4

Melanie has some of it, but, the real broblems happen when that lowering of the oceans temperatures actually stop the Northern and southern oscillations (El Nino, and Nina)

A better reference about this is in the explaination of what El Nino is.

Answer 5

Well first off,

The polar ice caps are melting, which is causing the water level in the oceans to rise (which is bad because land near the coast will get engulfed)

Also, because of the polar ice caps, the water will change the temperature of the ocean, which will likely change the air currents around the world. According to "An Inconvenient Truth" the sudden cooling of the air currents will trigger the next ice age.

Lastly, polar bears are drowning. If you think about it, Antarctica and the Artic is where the polar bears live. If the ice caps are melting into the ocean, that means the polar bears have less and less land to live on. Many polar bears are drowning because of the melting ice caps (http://www.timesonline.co.uk/tol/news/uk...
