It might be that a basket of vital indicators includes global mean surface temperature along with other indicators.

Once again under the widening impact of this full hour of extra solar radiation, global mean surface temperatures began to warm.

It is virtually certain that near - surface permafrost extent at high northern latitudes will be reduced as global mean surface temperature increases.

The figure below shows the change in precipitation and evaporation (which have to balance globally) against the global mean surface temperature change.

The strength of the radiative heat loss to space per unit warming of global mean surface temperature is a key quantity of interest, as usual.

Earth's annual mean surface temperature of 15 °C is 33 °C higher as a result of the greenhouse effect than the mean temperature resulting from radiative equilibrium of a blackbody at the earth's mean distance from the sun.

This is in contrast to externally forced variability in global mean surface temperature which arises due to changes in atmospheric greenhouse gasses, aerosols, solar irradiance, ect.

PAGES 2k Consortium [2013] reconstructed mean surface temperatures averaged over continental - scale regions.

The WMO bases its temperature assessment on global mean surface temperature datasets for January — September from several organisations, including the HadCRUT4 dataset compiled by the Met Office Hadley Centre and the University of East Anglia's Climatic Research Unit.

Removal of that hidden variability from the actual observed global mean surface temperature record delineates the externally forced climate signal, which is monotonic, accelerating warming during the 20th century.

First let's define the «equilibrium climate sensitivity» as the «equilibrium change in global mean surface temperature following a doubling of the atmospheric (equivalent) CO2 concentration.

When differences in scaling between previous studies are accounted for, the various current and previous estimates of NH mean surface temperature are largely consistent within uncertainties, despite the differences in methodology and mix of proxy data back to approximately A.D. 1000... Conclusions are less definitive for the SH and globe, which we attribute to larger uncertainties arising from the sparser available proxy data in the SH.

«Their study shows that the time - dependent response of zonal mean surface temperature differs significantly from its equilibrium response particularly in those latitude belts, where the fraction of ocean - covered area is relatively large.

In similar manner, it would be astonishing to find a modern climate science paper referencing that CO2 is a major driver of climate, or that changes in CO2 concentration have a direct impact on global mean surface temperatures unless the paper was from an entirely different field (where assumption of such basic knowledge can not be made), or where the reference is not for the fact of influence, but for a specific estimate of the value of the impact.

It is defined as the equilibrium global - mean surface temperature resulting from a sustained doubling of carbon dioxide concentrations (Gregory et.
