Green Hell clearly shows that we, as humans, have little or any impact on the atmospheric CO2 levels, and we DO NOT have the ability to lower these levels--even if all human, carbon emissions immediately ceased. Nothing would change.
Fear mongering by politicians and the scientific community has been a way of life for centuries. How many times has you read this or that would bring the world to an end. Remember Y2K? Remember the asteroid threat? How about the mini Ice Age that took place in an era when we had tons of gas guzzlers on our highways, vehicles that averaged 7 MPG.
In realistic terms, our atmospheric conditions seem to have improved significantly over the past century. This is especially true in the UK, California, and the mid-western U.S., locations where smog (smoke and fog) poisoned the air we breath to the extent where you couldn't see more than a few city blocks. Though most folks are too young to remember, there was a time when thousands of individuals died in London when smog was so dense that it caused suffocation for those who ventured outdoors.
Green Hell is a real eye opener, and as I stated earlier, it should be mandatory reading.
Gotta' go to work,

Almost forgot. A recent program on the History Channel, How The Earth Was Made, clearly reveals that sea levels during that particular era were not higher, but instead, land levels were lower. The program revealed how those mountain ranges worldwide were created, pushing skyward from the bottom of the sea by shifting of the planet's mantels and volcanic activity.
Cheers,
