Greenhouse warming is ruled out because there was no parallel increase of atmospheric carbon dioxide.

What's so frightening to them is that after one of the regular warming periods begins, they can see (in air bubbles trapped in glaciers from those past times) that CO2 starts increasing, and they know that this is because of the warming and thawing of vast natural stores of carbon dioxide in the oceans — as well as in the frozen or frigid earth of the northern tundra.

As for emissions, levels of carbon dioxide associated with electricity generation are near 30 - year lows, primarily because of increased use of cleaner - burning natural gas.

According to Wikipedia they explain the RE by saying: «If CO2 in the atmosphere is increased by one part per million, the CO2 in the ocean is increased by only a tenth of a part per million, because of the way that the carbon dioxide in the water is partitioned between carbonate ions and bicarbonate ions and free CO2.

The increase of CO2 is from humans because of the isotope signature of the carbon dioxide.

It is because of these effects of partial saturation that the radiative forcing is not proportional to the increase in the carbon dioxide concentration but shows a logarithmic dependence.

They do so because within these models the far more important radiative substances, water vapor and clouds, act to greatly amplify whatever an increase in carbon dioxide might do.

We discuss at length the increase in atmospheric carbon dioxide from some 300 to 400 ppm in + / - 300 years because, allegedly all by itself, it increases the Earth's greenhouse effect, which has / will increase the Earth's temperature.

Conversely, as atmospheric concentrations of carbon dioxide, methane, chlorofluorocarbons, and other absorbing gases continue to increase, in large part owing to human activities, surface temperatures should rise because of the capacity of such gases to trap infrared radiation.

Traditional anthropogenic theory of currently observed global warming states that release of carbon dioxide into atmosphere (partially as a result of utilization of fossil fuels) leads to an increase in atmospheric temperature because the molecules of CO2 (and other greenhouse gases) absorb the infrared radiation from the Earth's surface.

This is because it started from scratch at the turn of the twentieth century and to do this is impossible without an increase of atmospheric carbon dioxide.

In a sharp change from its cautious approach in the past, the National Academy of Sciences on Wednesday called for taxes on carbon emissions, a cap - and - trade program for such emissions or some other strong action to curb runaway global warming.Such actions, which would increase the cost of using coal and petroleum — at least in the immediate future — are necessary because «climate change is occurring, the Earth is warming... concentrations of carbon dioxide are increasing, and there are very clear fingerprints that link [those effects] to humans,» said Pamela A. Matson of Stanford University, who chaired one of five panels organized by the academy at the request of Congress to look at the science of climate change and how the nation should respond.

If you had said in the first place that you don't understand how a specific estimate is made of the extent of global warming to be expected from a specified increase in atmospheric carbon dioxide, I would not have tried to offer an explanation, because I don't understand that either.
