“I think they are realizing that lack of truth will be/is their demise”

If so, the realization is coming much too late, like the boy who cried “Wolf!” way too often.

First off, though carbon dioxide MAY have some effect on the climate, it pales into insignificance when compared to water vapor, which has an effect from some twenty times to as much as one hundred times the effect on the temperature of the atmosphere, compared to that of CO2. First off, simply because there is so MUCH water vapor, at any given time and under any given set of circumstances, as compared to CO2. Also water has some very peculiar characteristics NOT shared with carbon dioxide, in that it may exist in any of three different states of matter, somewht dependent on temperature, that does not happen with carbon dioxide.

Has anybody ever seen liquid carbon dioxide? It cannot exist except under special conditions of pressure and temperature, like some six times the normal atmospheric temperature of that which exists at sea level on Earth. The very fact that water exists as a liquid between the temperatures of 32 degrees Fahrenheit and 212 degrees Fahrenheit, is what makes life on earth possible in the first place. Also water has a very high specific heat index, much higher, for example, than most metals or non-metallic substances, and in fact, is the standard by which most other materials are measured. To pass from solid form ice to liquid form requires the input of a prodigious amount of energy, and to pass from liquid to water vapor requires about nine times more energy to change than the melting of ice. Even warming water up requires much more heat for each degree of temperature than warming up the same mass (weight) of most other substances. Conversely, to COOL the various forms of water dow requires that the equivalent amount of heat energy be RELEASED. And where is this energy released to? It radiates off the dark side of the earth when faced away from the sun.

So the cycle is largely self-correcting, with or without the assistance of mankind. Anthropogenic global warming (or cooling) is a myth, like the power of kings to command the tide.

However, we may harness this natural cycle of global warming (or cooling) to our benefit, and up to now, we have been carrying out a pretty respectable job of doing just that. Any carbon dioxide produced by the combustion of hydrocarbons (petroleum, coal and natural gas) is quickly taken up by growing green plants, with the net effect of keeping the average concentration of carbon dioxide at sea level to less than 400 parts per million. Below about 250 parts per million, is the starvation level for green growing plants, and without the CO2, they will wither and die.
