i linked this thread to a friend of mine who is taking various relevant science courses in university (i forget what all courses)
anyways here is his comments on your post.

There are lots of geologists who feel that global warming is a cyclical process, and there is evident to support it. I think your post is yet another example of someone knowing too much for their own good, and not enough to be complete.

1) CO2 is, just like this guy says, a benign gas which is integral to life as we know it. It is also experimentally proven absorb infared wavelength radiation and to vibrate (ie gain molecular kinetic energy, which is to say "get hot"). I have no idea what he's talking about with carbon neutrality, he's bastardized the notion by applying it to individual components. The carbon cycle is a large

and complex process involving all of the Earth. CO2 is definately causing greenhouse warming, which is definately keeping the Earth warm. As CO2 concentrations increase (and they have been steadily in recent years by about 1 ppm/year (about .25%)) the average temperature on the Earth is also increasing, so it follows that the two are strongly correlated. The reason that CO2 is suddenly the
says:
badguy is due entirely to fossil fuels. The Earth at some points in time may have had CO2 concentrations up to ~30%, that's 30 parts per hundred, right no it's 400 parts per million. It was almost a thousand times more abundant at points in the Earth's history. The question is; what happened to all that CO2? That CO2 was locked up in various reservoirs, including of particular interest: fossil

fuels. By burning fossil fuels we have undone millions of years of carbon concentration and storage and released it back into the atmosphere as CO2. This could potentially cause massive concentrations of CO2 in the atmosphere and result in huge changes in greenhouse warming as well as direct consequences due to the smothering amount of CO2.

2) There are many Earth's processes which appear to be cyclical, and many which simply are not. To say that Global Warming is nothing more than fear mongering (and it is, though there is fact behind it) is to ignore the consequences of what is essentially assured, dramatic consequences due to its existence. Global Warming is real and it will have dire consequences. Interesting that he mentions
says:
"six occurences of even more extreme versions of our global warming" yet fails to mention the numerous mass extinction events. I have no desire to refute nor agree with that statement, but I do wish to point out that large shifts in global environments causes huge extinctions. Assuming that nothing in the trend changes, the world will warm up and people will die due to it.

Global Warming is an annoying subject. The evidence points to it happening and that people burning fossil fuels are the cause.
