Climate Change

Here is one from an associate in New Hampshire:

"Dear Sen. Gregg:
Thank you for your thoughtful letter of July 22. I applaud the change in your views re. (cap and trade". The reasons you stated for not liking H.R. 2454 are all sound and sensible. Your whole letter was excellent, except for two items that I disagree with.
The first is climate change. To my knowledge there is no credible evidence that anything man does has any significant effect on the changes that take place in our climate, and have been taking place since man was on earth. I urge you to seek such evidence before drastically altering our economy through futile attempts to make such changes.
The second is that you apparently have made no effort to learn the science relating to any possible effect of carbon dioxide on global warming (or have done so and ignored it). For example, did you know that burning a fossil fuel generates about as much , or more, water vapor as it does carbon dioxode and that both are essentially equal in thermal conductivity, whch governs how those gasses transmit [heat] through our atmosphere? Ask the climate change fanatics why they aren't concerned about water vapor from fossil fuels or any other source.
I encourage you to consider true science, not just that promulgated by political or financial motives.
