55 million years ago we had massive global warming (known as the Paleicene-Eocene Thermal Maximum), with greenhouse gases reaching concentrations hundreds of times greater than what we are facing today. In a short period of time (10,000 years) the worlds temperature went up by 9 degrees Fahrenheit, the world changed and it took almost 200,000 years before it cooled down.

Many scientists attribute this to extreme periods of volcanic activity, but others are still searching for answers. That this event happened is a scientific fact and the best minds in the world have had years to review it, but cannot come to agreement on the cause.

No matter what their theories, no matter how much they hate President Bush, or love Al Gore, it’s hard to pin this one on the president and SUV’s. It should also serves a reminder that there is much that we do not know and if scientists cannot come to agreement on something that has already happened, why it is unreasonable to think that rational people can have different opinions on what might happen in the future – and why.
