Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

However climate models from even 20 - 30 years ago [Schneider and Thompson (1981); Bryan et al (1988); Manabe et al (1992)-RSB- predicted that the response of the Antarctic to enhanced greenhouse - induced warming would be much delayed relative to the warming expected to occur in the Arctic.

I don't think I try to poke holes at the idea that Arctic warming is «likely driven in part by the global greenhouse effect» but I do seek out weaknesses with suggestions that it is driven entirely, or to some very large degree, by a human - enhanced greenhouse effect (at least at the current time).

Whether the warming is from greenhouse gases, El Nino's, or solar forcing, trends aloft are enhanced.

They concluded that therefore with the tropical troposphere warming no more quickly than the surface, the warming trend had to be due to something other than the accumulation of greenhouse gases and enhanced greenhouse effect.

In fact, only warming by an enhanced greenhouse effect will warm nights more than day, polar regions (and especially the arctic *) more than tropical regions, and cool the stratosphere while warming the troposphere — all of which are features of the current warming.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

We can divide the atmosphere into a lower part (LP), which includes the surface and is the source of IR, and an upper part (UP), which we are asked to assume will cool when CO2 increases, in conjunction with the expected warming of LP from the enhanced greenhouse effect.

and first mention of «global warming» on pg xi The main greenhouse gas, water vapour, will increase in response to global warming and further enhance it»

Anthropogenic global warming (AGW), a recent warming of the Earth's lower atmosphere as evidenced by the global mean temperature anomaly trend [11], is BELIEVED to be the result of an «enhanced greenhouse effect» mainly due to human - produced increased concentrations of greenhouse gases in the atmosphere [12] and changes in the use of land [13].

This demonstrates that the 70.9 % increase in global CO2 emissions since 1980 did not in any way enhance the greenhouse effect as has been falsely claimed since 1988 when this global warming debacle first began.

AGW, also called «The Enhanced Greenhouse Effect» is simply the expectation from observation and theory that adding more of these gases will increase the «restiction» and that the Earth will warm as a consequence.

All this, while according to CO2 / AGW theory, The troposphere is what should see more warming due to «enhanced greenhouse effect» that occurs in the atmosphere.

Again, no significant trend of the global averaged Gaa [atmospheric greenhouse effect] is found from 2003 to 2014 (Fig. 2) because the enhanced warming effect over the western tropical Pacific is largely counteracted by the weakened warming influence on the central tropical Pacific.
