[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

This would actually not be true at sufficiently high latitudes in the winter hemisphere, except that some circulation in the upper atmosphere is driven by kinetic energy generated within the troposphere (small amount of energy involved) which, so far as I know, doesn't result in much of a global time average non-radiative energy flux above the tropopause, but it does have important regional effects, and the result is that the top of the stratosphere is warmer than the tropopause at all latitudes in all seasons so far as I know.

Though hurricanes strenthen when moving over warmer water, this is merely due to the fact that the horizontal temperature gradient of the atmosphere is not as steep, i.e. the temperature differential between the water and the atmosphere increases as the storm hits tropical waters; it is not the ocean temperature per se that drives the hurricane.

East Coast winter storms, known as «nor» easters» because of the unusual northeasterly direction of the winds as the storm spirals in from the south, are unusual in that they derive their energy not just from large contrasts in temperature that drive most extratropical storm systems, but also from the energy released when water evaporates from the (relatively warm) ocean surface into the atmosphere.

The big problem is that warming is driven not by annual emissions but by the accumulation of greenhouse gases in the atmosphere.

These overlooked, shorter - term pollutants — mostly from burning wood and kerosene and from driving trucks and cars — cause more localized warming than once thought, the authors of the report say.They contend there should be a greater effort to attack this type of pollution for faster results.For decades, scientists have concentrated on carbon dioxide, the most damaging greenhouse gas because it lingers in the atmosphere for decades.

But the suspicion is that the long - term trend in global warming driven by human combustion of fossil fuels that dump vast quantities of greenhouse gases into the atmosphere must be playing a part.

Although it is important to reduce the remaining climate uncertainties, such as the magnitude of the impacts of short - lived pollutants, it does not change the fact that CO2 is very likely the driving force behind the current global warming, or that if we double the amount of CO2 in the atmosphere from pre-industrial levels, the planet will likely warm in the range of 2 to 4.5 °C.
