What Causes Global Warming? What Causes Global Warming?

Scientists have determined that a number Scientists have determined that a number of human activities are contributing to of human activities are contributing to global warming by adding excessive global warming by adding excessive amounts of greenhouse gases to the amounts of greenhouse gases to the

atmosphere. Greenhouse gases such as atmosphere. Greenhouse gases such as carbon dioxide accummulate in the carbon dioxide accummulate in the

atmosphere and trap heat that normally atmosphere and trap heat that normally would exit into outer space. would exit into outer space.

The Green House Effect The Green House Effect

The "greenhouse effect" helps to moderate The "greenhouse effect" helps to moderate temperatures -- especially nighttime temperatures -- especially nighttime temperatures. Without the greenhouse effect, temperatures. Without the greenhouse effect, the average temperature of the Earth would be -the average temperature of the Earth would be -18 degrees C. 18 degrees C.

Greenhouse gases allow sunlight to pass Greenhouse gases allow sunlight to pass through Earth's atmosphere, but as sunlight through Earth's atmosphere, but as sunlight strikes the earth it is partially changed to radiant strikes the earth it is partially changed to radiant heat. Greenhouse gases like carbon dioxide, heat. Greenhouse gases like carbon dioxide, water vapor, and methane help inhibit the water vapor, and methane help inhibit the escape of radiant heat back into spaceescape of radiant heat back into space

Effects of Global Warming Effects of Global Warming

Glacier retreat and disappearance 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
