I'm still waiting for the explanation of how sunspots warm the northern hemisphere but not the southern. Guess the southern hemisphere is in the shade.
There certainly wouldn't be any plants without any co2. But no, earth won't necessarily be a frozen wasteland. Doubling co2 alone would cause about a 1C rise in temps. Then you would wait for feedbacks to kick in to add on top of that... Dr. Lindzen here said that the current climate is mostly based on watervapor and clouds, and if the earth was completely deprived of co2 it would be 2.5C lower. About 47 minutes into this panel discussion
Lindzen seems to like to interrupt any rational discussion with nonsensical statements not based on any evidence or the known laws of physics. One has to wonder if he does it just to confuse the issue.
In any case, in this instance, he is wrong (as he often is)- by an order of magnitude:
"Ample physical evidence shows that carbon dioxide (CO2) is the single most important climate-relevant greenhouse gas in Earth’s atmosphere. This is because CO2, like ozone, N2O, CH4, and chlorofluorocarbons, does not condense and precipitate from the atmosphere at current climate temperatures, whereas water vapor can and does. Noncondensing greenhouse gases, which account for 25% of the total terrestrial greenhouse effect, thus serve to provide the stable temperature structure that sustains the current levels of atmospheric water vapor and clouds via feedback processes that account for the remaining 75% of the greenhouse effect. Without the radiative forcing supplied by CO2 and the other noncondensing greenhouse gases, the terrestrial greenhouse would collapse, plunging the global climate into an icebound Earth state."
I think I'll set a few quarts of used motor oil on fire to help prevent this global cooling. Which is more than what the liberals have done to help even after spending endless billions on their global warming religion.
Well, so much for the rapid "global warming" predicted by the so-called climate "experts".
Wrong again, fellas.
Okay so all of these scientists all around the world coming up with the same conclusive evidence just so happen to be NWO conspiracy terrorists... alrighty.. steps away from idiotic debate.
Just like Global Warming, also don't believe the earth had the "Ice Ages", that covered northern North America, as the science books claim. However, we have had some very warm periods and some very cool periods, like the "Little Ice Age." According to the data on the number of sunspots, we do seem to be going into a cooling phase, as there is less solar activity and fewer sun spots. For the USA, it means more winters like the last few, when the Great Lakes almost froze over. So stock up on firewood and sweaters.
