I happened to catch your radio show earlier today and I was pleased with the content, even if I didn't agree with everything. You seem like a level headed guy who is well educated on the subjects you speak of, go figure.
My reason for contacting you has to do with the last caller you had on the show. He referenced the global warming theory and although I am not sure he made a strong argument for his case, I agree that there is more to the story.
You stated that you tend to believe the researchers and scientists who claim that global warming is caused by CO2 or green house gases. This would make total sense except the data that they are finding actually proves that the world is cooling. The reports they publish are skewed in a way to strengthen the case for global warming, however the data itself weakens their stance.
I assume you are aware of the emails that were found to suggest that the scientist were hiding evidence that contradicted their stance. There is a lot of money to be made on the "green" technology and therefore there is a LOT of money in keeping people fearful of their "carbon footprint".
Scientist Piers Corbyn has challenged many of the "scientist" to provide actual data to prove their theory and thus far they have not done so. He has a lot of data to prove the earth is in fact cooling, however not to any dangerous level.
