You may not know this, but I am a scientist. I have two degrees in Chemistry. Part of my graduate work was in Analytical Chemistry. I have seen, used and built a lot of scientific instrumentation. So the whole Al Gore thing interests me as a scientist. I did a little research. I didn’t have to go far before I found this: “The Great Global Warming Swindle”
I did a little checking and found that Al Gore isn’t a scientist, but these guys are. That shouldn’t automatically discredit Al Gore. He did have scientists working for on this project.
Here is something “The Great Global Warming Swindle” points out. The above graphic is from Al Gore’s documentary. The red line (top) is CO2 concentration in the atmosphere and the blue line (bottom) is the surface temperature of the earth. It is clear the two are related. Al Gore says that when CO2 goes up, the temperature goes up. The scientists in “The Great Global Warming Swindle” say that a rise in temperature causes CO2 concentrations to go up (scroll in to the twenty minute mark).
They say the CO2 concentrations increase hundreds of years after the temperature increases. They show a graph with a much more granular time axis so you can see the lag of the CO2 concentration. With Al Gore’s chart showing 50,000 years at each clip, it is difficult to tell. Al Gore makes a point of saying that zero scientists dispute this relationship between CO2 and temperature. He failed to say that some scientists think it is the other way around.
I’m looking for a reliable resource (other than these videos) for the breakdown of the percentage contributions of different greenhouse gases. I would really like to know how much the average volcano emits compared to all the cars in an average sized metropolitan area. I’ll keep you posted on what I find.
