Your global warming show could have been so much better with a reasoned, balanced approach discussing the true science which makes anthropogenic global warming completely idiotic. Instead you were bombarded by ridiculous questions based on false assumptions. I expected you to raise questions which challenged the global warming religion. Things you should have mentioned:
1. Temperatures in 1000AD were two degrees warmer. The Vikings grew crops and settled Iceland and Greenland during this period. Man thrived during this period. Its global cooling that kills with crop failures and starvation.
2. The one degree of global warming we have had over the last 200 years starts from a low point in a mini ice age. Remember how cold things were at Valley Forge.
3. CO2 is present in only trace amounts in the atmosphere and has to be measured in parts per MILLION. For every molecule of CO2, there are 2500 molecules of N2, O2, water vapor and argon. At 100% humidity, H2O, a strong greenhouse gas is 120 times more abundant than the weak greenhouse gas, CO2. The increase in CO2 levels of 80 ppm over the last 100 years is miniscule.
4. In geologic time, CO2 levels are at record lows. Most of the biosphere evolved when CO2 levels were much higher. In fact over the last few million years, plants evolved a new photosynthetic pathway to capture more CO2, event hough the C4 pathway requires more energy (ATP). There is a CO2 famine for plants, especially plants that only use the C3 pathway.
5. Increasing atmospheric CO2 is beneficial. Crops and trees grow 30 to 40 % better with more CO2. CO2 is added to greenhouses. The CO2 effect is even more pronounced when plants are under stress, such as in low water conditions
6. Al Gore and his propaganda movie shows a relationship between world temperatures and CO2. Gore's assertion that CO2 increases temperatures is backwards. Ice core samples show that first temperatures rise, followed 800 years later by a rise in CO2. This relationship is easily explained by the fact that cool water can dissolve more CO2 than warm water. the proper sequence: The sun increases solar (sunspot) activity, the oceans warm and release CO2. When sun activity declines, the oceans cool and CO2 is absorbed from the atmosphere.
7. If you look at the real science, and you look at the dramatic rise in world population (from 1 billion to 6.5 billion) over the last century, one can make a very logical argument that the US should be building many more clean coal fired electric plants that only emit CO2 and water vapor. This would emit more CO2 into the CO2 starved biosphere, Crops would grow better, and the US with its abundant coal reserves could become energy independent.
