First, the scientific evidence for your claims is in one word, JUNK. For proof of the junk status, their predictions have already failed badly.

Again, once again, over again, yet again, one more time, this time just for you, in science, when predictions are proven badly wrong, then we junk the science. That's much of why we do look to science for solid answers.

As in the graphs in the link I gave, nearly all the models have been proven badly wrong; just click on the link and look at the picture; download the picture and use a graphics program to zoom in on the details.

So, due to the bad predictions, we junk the models.

Now we are very short on scientific evidence.

The long dark ages of the ascent of man show that non-scientific evidence is ugly, disgusting, dangerous stuff -- snake oil, witches' brews, toxic swill, leach bleeding, burning girls alive at the stake, horrible human suffering, e.g., get the Black Death, kill about a third of the population and have dead bodies piled up in the streets from the bacteria from the fleas from the rats because some idiots killed off the cats that were eating the rats.

Second, you are concentrating on CO2, and there is next to no solid evidence that CO2 is having any effect now on the temperature of the earth at all. For evidence, over at least the last few thousand years, higher temperatures were not preceded by higher CO2 concentrations (except for pulling out of the Little Ice Age clearly caused by fewer sun spots so that the pulling out was likely caused by normal sun spot activity and not the CO2 from the industrial revolution -- also note the cooling of 1940 to 1970 when if anything CO2 concentrations were higher)
and lower temperatures were not preceded by lower CO2 concentrations.

Third, some of the best evidence is that the temperature variations in the earth over the past few thousand years at least up to the present are due to variations in sun spot activity with CO2 just irrelevant. The sun spot data actually fits the temperature data, and the CO2 data very much does not. A biggie is the Little Ice Age -- lower sun spot activity but not lower CO2.

Your claims that it's so hot now are from data cooked by NOAA and NASA due to what Obama and the global warming alarmists wanted. Or, really, how much warmer is it, since when, in degrees C, measured how, by whom, when, and published where? At best you are talking changes too small to be at all sure about. More likely you are being fooled by deliberately fraudulent data.

For a little more, as of 2006, the US National Academy of Sciences report, right, still at

http://www.nap.edu/catalog/11676.html

quite carefully showed (A) that the temperature of the earth in 2006 was essentially the same as in year 1000 before the Little Ice Age, and the increase in temperature in the 100 years before year 2006 was very much like the increase in temperature in the 100 years before year 1000. Just see the graph early in the report. The time series statistics were from David Brillinger at Berkeley, a student of John Tukey at Princeton and Bell Labs, and Brillinger is a good candidate for the best time series guy on the planet. It's a serious report. Clearly the increase in temperature before year 1000 was not caused by an increase in human emissions of CO2. So, CO2 is not the only cause of temperature increases or changes. So there must be other causes. So, even if you do all you want against CO2, the other causes might remain and, really, make your CO2 efforts a total waste.

Or, again, yet again, once again, over again, one more time, this time maybe you will pay attention: The Little Ice Age was real, e.g., was the cause of the ice on the Delaware River in the famous painting of Washington crossing that river and of the extreme cold when Napoleon left Moscow. Well, the Little Ice Age certainly was not caused by lower CO2 concentrations. So, why, oh why do you continue to believe that changes in CO2 concentrations are the only cause, or now even a significant cause at all, of changes in global temperature? Nothing could be more clear: (A) At the start of the Little Ice Age, temperature went down, but lower CO2 was not the cause. (B) CO2 changes are not the only cause of temperature changes. You are fully able to see this.

Warmer? Heck there was some significant warming: In the Middle Ages, they were growing grapes in England! That's warmer than now! And that warming was not from higher CO2 concentrations.

And, for more, there was nothing very unusual about the temperature in year 2006. And since year 2006, the change in temperature has been too small to be at all sure the change was not actually zero -- there's been no significant change since year 2006. Net, we're not warmer than in year 1000 when CO2 was irrelevant, and, again, it is not clear that CO2 now is having any effects at all.

Due to sun spots or whatever, it really might be warmer in 20 years as you fear. No one really knows. The IPCC doesn't know; I don't know; no one knows what the sun spots might do; no one knows what the effect of realistic amounts of CO2 might be; there is no good evidence; the evidence that CO2 is a big danger is junk science seriously debunked by the bad predictions I referenced; and you don't know.

You are back to the thinking of the Mayans who killed people to pour their blood on a rock to keep the sun moving across the sky. You want stop humans from emitting CO2 to keep from warming the planet, and your evidence is, net, no better than that of the Mayans. Your solution is similar: Sacrifice.

Or, you have in mind a classic trilogy: (A) Human transgression, sin, this time against Mother Earth, (B) retribution from an angry god, Mother Earth, with global warming that hurts our children, (C) redemption for our sins from sacrifice, like the Mayans did, that causes us to suffer, e.g., shut down much of our economy. You are going for the attractions of an old pagan religion. You are being manipulated by people who want money from subsidies, etc. No thanks. Wise up.

We don't know what the climate will do. We can't cure all cancers, either. Relax. For CO2 and the climate, f'get about them. Do something else.

And, no carbon taxes. No higher electric bills. No attacking our cars, trucks, and airplanes. No shooting our economy in the gut. No thanks.
