First, I am a trained and long-practicing scientist, and I look at data dispassionately. Just the facts, the data, the logic, please, and we try as much as humanly possible to push for objectivity and suppress any emotional reactions we might have.
When the subject of what is properly called Anthromorphic Global Warming (AGW), that is, planetary warming caused entirely by human activity, came up years ago, I was immediately interested. As a chemist I know that the CO2 molecule is excited by sunlight and generates heat, thus a rise in atmospheric CO2 concentration was a logical suspect for the possibility of warming.
However, the Romans had a saying about poisons, that dosage size is all important, and that's very true. You can kill yourself drinking too much water, or taking too much salt, both of which are essential to life. When it comes to CO2 and warming, it turns out that all the calculations show that you need a high concentration, like a few percent, of it in the air to really trap enough heat so that the planet can't reflect it back out to space fast enough and the temperature must rise over time.
However, the level of CO2 has gone from under 300 parts per million to just about 400 ppm in the last hundred years or so. Even at 400 ppm, that is actually 0.04%, and nobody, even the most fervent believers, will maintain that such a level of CO2 can, by itself, warm the planet.
So how do they all make the dire predictions we've seen? By the theory that a small rise in CO2 brings on a large rise in water vapor in the atmosphere, and the H2O molecule is the one, at actual percentage levels, that will trap all the heat. Only problem is that there is total ZERO data supporting this theory, and on a planet with 2/3 of its surface covered by water, hit by the sun, and whipped up by winds and waves, it would seem really more likely that other factors are what control planetary humidity.
Can the planet be warming? Sure it can, we're still coming out of the last ice age. But the best data we have on planetary temperature is from the millions of satellite readings, and they show no serious trend in temperature climb for the past 18 years. The believers call this "the pause" and have no explanation for it.
If indeed warming is underway, and that is possible, it is very slow, and related to things other than human produced CO2. Since India and China and other parts of the world aren't even really considering slowing down their use of coal and fuels, nothing we can do will make any difference, other than to raise the price of energy here, cost us all more money, make us less competitive internationally, and make the fat cats who want to run the "carbon exchanges" billionaires. The right answer to whatever warming there is will be breakwaters, dikes, levees, etc, which human beings have been able to make for a very long time already. Thinking we can somehow stop and reverse whatever warming is going on for the planet is like the ant running up the elephant's leg with intentions of rape..... way, way too ambitious!
