After watching "The Day After Tomorrow", I have had an interest in global warming and for some reason, marine life. Althought the interest in marine life must've been sparked by the episode of Seaquest DSV I just watched a week ago.

Anyway, here is an excerpt from an article about global warming that I have read.

The central problem

We therefore add our voices to those urging more serious attention, and action, from national and international bodies. The central problem is one of the massive transfer of carbon from beneath the ground into the atmosphere, caused by humanity’s enormous demands for energy, and current dependence on fossil fuels to supply by far the greatest part of this energy.

It is hard to convey the sheer scale of this carbon transfer. In numbers, it currently runs at some 6.5 billion tons each year. How can one visualize this? If the Great Pyramid of Khufu were made of diamond, the densest and most compact form of pure carbon, it would weigh some 6.5 million tons. So, globally, our annual carbon transfer, through fossil fuel burning, to the atmosphere is equivalent to one thousand Great Pyramids, all made of diamond. We burn, each year, around a million years worth of accumulated hydrocarbons.
