Milankovitch Cycles. Maunder Minimum. Medieval Warming Period. Growing grapes for wine in Roman-era England. Ice cores from Greenland. CO2 not as powerful of a greenhouse gas as WATER VAPOR. The hydrologic cycle as it relates to the aforementioned water vapor.
...all of which argue AGAINST Mr. Tyson. As a scientist, you would think he'e be required to KNOW THIS SH!T, eh?
...not much of a scientist, I must conclude.
Oh, and Salon...well, 'nuff said. It's a rag.
What many of these fools don't understand is that if their theory about greenhouse gases were correct, there never would have been life on this planet.
Water vapor is the dominant greenhouse gas. Above Freezing it exhibits the greenhouse gas effect of absorption and re-emission of energy. This creates a positive feedback effect that warms the planet.
When water vapor gets to a certain level, it forms clouds which reflect light before it gets a chance to warm the ground and the lower levels of atmosphere. It becomes a negative feedback effect.
CH4 and C02 are trivial in comparison to the effect of a substance that diffuses into the air from 3/4ths of the Earth's surface.
Water vapor regulates the temperature on planet earth through both positive and negative feedback effects, and it mitigates any extremes.
If any of these idiots actually had any actual knowledge of science, they would not be so cocksure about their opinions. (Which are wrong.)
