GLOBAL WARMING

What is Global Warming? Is a phenomenon that has been happening for a long time. The temperature of the earth has been increasing more or less continuously since the time of the cave man. Approximately 18,000 years ago the earth began a gradual process of warming up after more than 100,000 years of Ice Ages. Much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice.

What Causes Global Warming? Scientists have determined that a number of human activities are contributing to global warming by adding excessive amounts of greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the atmosphere and trap heat that normally would exit into outer space.

The Green House Effect The "greenhouse effect" helps to moderate temperatures -- especially nighttime temperatures. Without the greenhouse effect, the average temperature of the Earth would be -18 degrees C. Greenhouse gases allow sunlight to pass through Earth's atmosphere, but as sunlight strikes the earth it is partially changed to radiant heat. Greenhouse gases like carbon dioxide, water vapor, and methane help inhibit the escape of radiant heat back into space

Effects of Global Warming Glacier retreat and disappearance Greenland's glaciers are melting even faster than previously thought and contributing more and more to sea level rise caused by global warming. If you live near the sea and think global warming isn't a problem for you, it's probably time to think again. The latest reports on increased levels of glacial discharge, in the journal Science, reports the amount of ice being dumped into the ocean from the Greenland Ice Sheet has doubled in the last 5 years. A full breakdown would result in a catastrophic global sea level rise of 7 meters. That's bye-bye most of Bangladesh, Netherlands, Florida and would make London the new Atlantis
