Mars has almost no water vapor (about 210 ppmv), and water vapor is a much stronger greenhouse gas than carbon dioxide.

If the U.S. keeps building new coal - fired power plants without CCS (a technology still in development that is intended to take carbon dioxide out of emissions), we can't very well ask or expect other countries (e.g., China) to care much about the issue, unless they decide to care for their own reasons.

Research indicates that oceans have absorbed much of the heat and about a third of the additional carbon dioxide pumped into the air from pre-industrial times.

I'll give an example because a) I want to show the traditional use of «heat and light» and some other points I've made but b) this page too has slipped in a fake fisics meme, much as a lot of papers do giving real research results which then slip in something about «global warming» or carbon dioxide» to justify their grant..

The history of climate change goes back much further: in the 19th century, physicists theorised about the role of greenhouse gases, chiefly carbon dioxide, in the atmosphere, and several suggested that the warming effect would increase alongside the levels of these gases in the atmosphere.

Similarly, they produce about twice as much greenhouse carbon dioxide and other atmospheric pollutants;

-LSB-...] Yes carbon dioxide is a cause of global warming, but it's so minor it's not worth doing much about.»

There has been much ado about flashier carbon - capture systems, like geologic sequestration, which involves collecting carbon dioxide and injecting it deep below the Earth's surface — into depleted oil or gas wells, for example.

The whole debate about Global Warming is exactly how much carbon dioxide one has to add in order to change world temperatures; but no one disputes that, eventually, too much carbon dioxide will increase the temperature.

This route of consideration entails the inference of what we'll call each respective warmist's primary and secondary gain motivating his allegiance to this objectively insupportable (and factually unsupported) damnfool contention about the adverse effects of anthropogenic atmospheric carbon dioxide and — much more importantly — the political measures being pushed by each such statist sumbeech in order to allegedly ameliorate the tissue - of - lies «externalities» nonsensically asserted to be associated with the complete combustion of petrochemical fuels upon which all of industrial civilization depends for its function.
