I have no way of knowing the influence of «family relationships» between models, but it is clear that a large part of the apparent correlation of projected warming rate with average surface temperature is due to more runs for some models than for others, combined with the close relationships between certain models.

Global average temperature is lower during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth surface was more reflective, due to the presence of lots of ice and snow on land, and lots more sea ice than today (that is, the albedo was higher).

I found that the general belief is that the average surface temperature over the whole earth for a whole year has increased from ~ 288 K to 288.8 K in roughly 150 years, i.e. 0.3 % and that it is due to increased CO2.

During that same period, average annual rainfall in New South Wales declined by 3.6 inches (92 millimeters).3 Scientists think the decline in autumn rainfall in southeast Australia since the late 1950s may be partly due to increases in heat - trapping gases in Earth's atmosphere.3, 14 Major bushfires over southeast Australia are linked to the positive phase of an ocean cycle called the «Indian Ocean Dipole» — when sea surface temperatures are warmer than average in the western Indian Ocean, likely in response to global warming.15, 16

Harvey's rapid intensification from a tropical depression to an 85 - mile - per - hour hurricane in less than 24 hours was due to favorable conditions — warm water and low wind shear [29]-- in the Gulf of Mexico, where sea surface temperatures were up to 2.7 - 7.2 °F (1.5 - 4 °C) above the 1961 - 1990 average.

For example, since showing lights at night was generally not a good idea because of the submarine threat, maybe the measurements were biased more to daytime measurements, where the surface was generally warmer due to solar heating, than to average temperatures over the whole day which would be more typical of peacetime.

The 255K equilibrium temperature with the Sun at the TOA + 33K due to the average lapse rate sets the surface temperature at 288K or 15C.

While I don't doubt the way the amount of IR absorption by CO2 increases due to spectral detuning (I'll accept the quantum mechanics expert's opinions on that), for the life of me I can't see why that should carry over to the average surface Temperature of the whole planet.

Nothing, right... except when you consider that the radiative forcing due to doubling of the atmospheric concentration of carbon dioxide is only about 3.7 W / m ², and that's expected to change the average surface temperature by about 3 °C, eventually ³.

Normally you can run GCM for centuries with a stable realistic surface temperature, but take the CO2 out, and in 5 - 10 years it has dropped 30 C in global average temperature and is half - covered in sea ice due to a powerful water vapor feedback in response to any global temperature change.

Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

Just a bit less average surface winds would result in lower evapiration and higher surface temperatures due to less mixing of lower and higher air strata.

The gradual rise in the global surface temperature from 1978 to 1998 appeared to confirm the statement in IPCC2007 p. 10 that, «Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations».

This gives $ T = Q / (c * m) = 0.00005 K for the increase of the average bulk temperature of water (from surface and up to 5 cm deep) due to the increase of the back radiation by 0.062 W / m ^ 2.

I should also have made the point that using the same Figures 4.4 and 4.5 from the referenced report, that one can conclude most of the HadCRUT4 global average surface temperature warming observed from 1970 — present was due to NATURAL causes, as 0.3 C of the approx. 0.55 C warming was due to the 62 year natural cycle with amplitude of + / - 0.15 C.

Quite off the mark, surface temperatures are mostly average because there is still some ice reflecting sunlight, but sunlight is very intense due to low cloud extent and high sun elevations, and does not show immediately above the ice, but further up.

So how can we possibly start talking about anthropogenic forcings and surface temperature changes wrought by same when we don't even know to + -5 C what the average temperature of the earth should be due to our albedo measurements being so imprecise and having no bloody idea how, when, and why the earth's average albedo varies.

«Despite a wide range of climate sensitivity (i.e. the amount of surface temperature increase due to a change in radiative forcing, such as an increase of CO2) exhibited by the models, they all yield a global average temperature change very similar to that observed over the past century.

These feedbacks are the primary source of uncertainty in how much the earth will warm (side note: the question that most climate scientists who study the forcing due to CO2 try to answer is, how much will the long - term globally averaged surface temperature of the earth rise due to an rapid rise of CO2 to twice its industrial level, that is, 270 ppm to 540 ppm; it is currently about 380 last time I checked, and rising at ~ 3ppm / year, although this rate of change appears to be accelerating).
