There are some who, lacking the ecstatic thrill of any other faith-based religion, wish to believe that the Earth is in the early stages of an unprecedented climatic change which will see temperatures soar, the polar ice caps melt, rising sea levels flood our coastal cities -- general devastation on the biblical model -- all because we insist on driving petroleum-fueled private automobiles and using electricity generated by burning coal.
Burning that stuff releases into the atmosphere large amounts of carbon dioxide, you see, a "greenhouse gas" that contributes to the ongoing warming of the planet.
Now, this is almost entirely fantastic nonsense. ...most of the CO? in the atmosphere comes from volcanoes and the natural processes of the oceans, not from man-made sources.
How about examining the historical record for the approximately 200 years for which we have reliable weather data? Look to see if there was a period when the weather cooled down, all of a sudden, and what caused it.

Google "Year Without a Summer." From April 5 to 15, 1815, Mount Tambora on the island of Sumbawa in the Dutch East Indies (modern-day Indonesia) blew up, ejecting 40 cubic kilometers of volcanic ash (more than twice as much as the 1883 explosion of Krakatoa) into the upper atmosphere.

That stuff stayed up there, in the jet stream, for more than a year.

Ditto here in central Texas, where it’s currently 84 degrees, and we received 6 inches of snow Easter weekend.
No, he’s just trying to prove Dean Wormer was wrong about him, he can go through life “fat, drunk and stupid.”
Man's contribution of CO2 dwarfs vocanoes, I think by a 10 to 1 factor. Some skeptics have admitted their error on this.
Can you believe it is July 2 in Houston? Of course I have mold growing on everything I have from all the rain, but it’s not hot!
The answer i a government program mandating that everything be painted white. Each spring you will be required to spray paint all new foliage and grass white. White roof’s, white cars, white houses and bald heads. It’s a left wing albedo thing.

“Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times.”

“Volcanic eruptions can enhance global warming by adding CO2 to the atmosphere. However, a far greater amount of CO2 is contributed to the atmosphere by human activities each year than by volcanic eruptions. Volcanoes contribute about 110 million tons/year, whereas other sources contribute about 10 billion tons/year. The small amount of global warming caused by eruption-generated greenhouse gases is offset by the far greater amount of global cooling caused by eruption-generated particles in the stratosphere (the haze effect). Greenhouse warming of the earth has been particularly evident since 1980. Without the cooling influence of such eruptions as El Chichon (1982) and Mt. Pinatubo (1991), described below, greenhouse warming would have been more pronounced.”

Water vapor, a greenhouse gas fluctuates much more than 0.008% (1/125th of 1%).
How much effect does water vapor have compared to CO2? And has it increased, accounting for the increase in global temperatures?
Does water vapor reflect energy back into space, acting sometimes as a global cooler?
If an increase in water vapor increases global warming, does the warming generate more water vapor, yielding a positive feedback loop? If so, what counters the loop?
How many degrees would the earth’s temperature drop if all the CO2 disappeared from the atmosphere? How many degrees increase if CO2 doubled, trebled, or quadrupled?
I don’t know the answers.
