Not only that, people who won't notice climate change and who will not alter their behavior are like the HIV stricken bath-house patrons, who shoved their fatal doses, all the way past AIDS, to a deadly epidemic. Don't be so surprised.
You seem to be preoccupied with aids? Are you perhaps a victim? Or maybe wondering if you should get tested but afraid to do so?
Such skeptic websites seem full of rants, decrying known outcomes and reporters. At least Watt has a graph or several. If Mr.Pielke has a doctorate, all he does at his website is quack, quack, the Greenland ice is frozen again. I have no respect, for this sort of media.
Do feel free to bring a rant from his website. He is an imminent scientist who, by the way, believes in AGW. Strange that you would dis him so. Certainly no one else does. The climate science community defended him when he was badly treated at skeptical science.
Starting at the end of the 18th Century, but accelerating, in the 1950s, CO2 concentration started skyrocketing, so it is all the way, to 400 ppm, when it was 280 ppm, c. 1800. There will be no global cooling, in our lifetimes, or for many lifetimes, thereafter, unless GHG emissions are controlled, and CO2 respirators somehow flourish, instead of succumb.
Nothing unusual there. Both the roman warm periods and the medieval warm periods warmed much more quickly and to a greater degree than the present and the holocene maximum saw more warming at a more rapid pace than either of those two. As to the cooling, I believe you are wrong. Now that it is clear that the claimed warmig is less than half of what has been claimed, it is impossible to tell whether it is actually warming or cooling as the claimed temperature changes are much larger than the margin of error.
Although I would like to see a warmer climate. The earth is quite cold right now relative to its normal temperature over the span of its existence.
GHGs now include a lot of industrial gases, and CH4 is out-gassing, as a direct result, of human industry and neglect of environmental degradation.
CH4 can no more trap and retain heat in the atmosphere than CO2. It absorbs, it emits. Emission tends to scatter that which was absorbed which is a cooling action as opposed to a warming one.
Gosh, ice isn't normal, except ALL THE TIME. Since we have been at a thermal maximum, with temperatures trying to move downward, on schedule, I suspect you didn't notice any of the other GHG-preceded warmings, such as the PETM or the P-T extinction.
You are thinking in very short terms. When the earth began to decend into the ice age that we are currently warming out of, the average temperatuer of the earth had been about 8 degrees C warmer than it is at present for the previous 75 million years or so with atmospheric CO2 numbers several orders of magnitude higher than they are today.
As to the PETM and PT extinctions, there isn't a whit of hard evidence that atmospheric CO2 had anything whatsoever to do with them. Such a claim is nothing more than fearmongering. If you can show some hard proof to support the claim, by all means, lets see it.
