This can be affected by warming temperatures, but also by changes in snowfall, increases in solar radiation absorption due to a decrease in cloud cover, and increases in the water vapor content of air near the earth's surface.2, 14,15,16,17 In Cordillera Blanca, Peru, for example, one study of glacier retreat between 1930 and 1950 linked the retreat to a decline in cloud cover and precipitation.18

A new study of the temporary slowdown in the global average surface temperature warming trend observed between 1998 and 2013 concludes the phenomenon represented a redistribution of energy within the Earth system, with Earth's ocean absorbing the extra heat.

One study estimates that there are likely to be places on Earth where unprotected humans without cooling mechanisms, such as air conditioning, would die in less than six hours if global average surface temperature rises by about 12.6 ° F (7 ° C).16 With warming of 19.8 - 21.6 ° F (11 - 12 ° C), this same study projects that regions where approximately half of the world's people now live could become intolerable.7

«The assessment is supported additionally by a complementary analysis in which the parameters of an Earth System Model of Intermediate Complexity (EMIC) were constrained using observations of near - surface temperature and ocean heat content, as well as prior information on the magnitudes of forcings, and which concluded that GHGs have caused 0.6 °C to 1.1 °C (5 to 95 % uncertainty) warming since the mid-20th century (Huber and Knutti, 2011); an analysis by Wigley and Santer (2013), who used an energy balance model and RF and climate sensitivity estimates from AR4, and they concluded that there was about a 93 % chance that GHGs caused a warming greater than observed over the 1950 — 2005 period; and earlier detection and attribution studies assessed in the AR4 (Hegerl et al., 2007b).»

Because the temperature gradient in a planet's troposphere is the state of thermodynamic equilibrium which the Second Law of Thermodynamics says will evolve, the planet's supported surface temperature is autonomously warmer than its mean radiating temperature, so warm in fact on Earth that we need radiating gases (mostly water vapour) to reduce the gradient and thus cool the surface from a mean of about 300K to about 288K, this being confirmed by empirical evidence (as in the study in my book) which confirms with statistical significance that water vapour cools rather than warms, all these facts thus debunking the greenhouse conjecture.

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).

Beginning (near the turn of the 20th century) with the theoretical studies of Svante Arrhenius about how infrared absorbing gases help determine the surface temperature of the earth; then spurred by the reexamination of those models in the 1950's, by Roger Revelle, and in the 1960's, by Jule Charney; and then James Hansen's modeling of the unique green - house - gas (GHG) forcing of the very hot atmospheric temperature of Venus — climatologists and geophysicists began to vigorously reexamine such models in greater detail.
