Say for a fact that we know that man is the main driving factor behind climate change. Just because the temperature has risen from a global minimum and CO2 has increased during the same time frame doesn’t mean that CO2 and methane are driving the temperature change.
For MTR and others who spout the use of tree rings etc to recreate past temperature history, than why does the US EPA now is seriously doubting this information? That is one of the points that I am trying to make, the more research into the climate the more the AGW models are being filled with doubts.

I have been reading a number of articles about changing to hydrogen cars and how it would result in a decrease in pollution. While it is true a hydrogen car would be a number of times cleaner than a regular gas car, I have a few doubts about how clean the hydrogen making process would be. If hydrogen obtained from water, wouldn’t it require a great deal of energy to get the hydrogen out of it? Wouldn’t the energy required to do this come from oil and the more traditional non-green energy sources? Overall, is the process for obtaining enormous amounts of hydrogen overall green at all?
