Of course, while short - term changes in sea level can be predicted fairly accurately based on the motions of the moon and sun, it is a lot harder predicting the ups and downs of the average global surface temperature — there is a lot of noise, or natural variation, in the system.

The average global sea surface temperature tied with 2010 as the second highest for January — August in the 135 - year period of record, behind 1998, while the average land surface temperature was the fifth highest.

An average surface temperature of 300 ºF (149 ºC) below zero allows water to build and form impressive, rugged mountain ranges, while nitrogen ice remains relatively malleable.

The standard assumption has been that, while heat is transferred rapidly into a relatively thin, well - mixed surface layer of the ocean (averaging about 70 m in depth), the transfer into the deeper waters is so slow that the atmospheric temperature reaches effective equilibrium with the mixed layer in a decade or so.

My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years on Earth with global average land and ocean surface temperature anomaly below 1C above pre-industrial average (using 1850 - 1900 proxy).

It stands to reason that the oceans haven't been that warm in a while but since the average temperature of the whole mass of water is so dependent on circulation (it's only the surface temperature that's constrained by its interactions with the atmosphere and space), I suppose a plausible history of that particular value would be very hard to reconstruct.

Their work is a big step forward in helping to solve the greatest puzzle of current climate change research — why global average surface temperatures, while still on an upward trend, have risen more slowly in the past 10 to fifteen years than previously.

While the warming of average global surface temperatures has slowed (though not nearly as much as previously believed), the overall amount of heat accumulated by the global climate has not, with over 90 percent being absorbed by the oceans.

The global temperature records use a blend of air and sea - surface temperatures, while global average temperatures from climate models typically use just air temperatures.

Pritchard noted that the Antarctic Peninsula's annual average air temperature has risen 5.4 degrees Fahrenheit (3 degrees Celsius) since 1950, while near - surface ocean waters have warmed 1.8 degrees Fahrenheit (1 degree Celsius).

While none of the numbers may sound large to laypeople, they are averages for the surface temperature of the entire planet, and therefore represent enormous additions of heat to the Earth.

They conclude that while the rate of increase of average global surface temperatures has slowed since 1998, melting of Arctic ice, rising sea levels, and warming oceans have continued apace.

Moreover, since 1960, solar activity has declined slightly, while the average global surface temperature has increased by more than 0.5 °C.

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.

Venus's average surface temperature is 864 degrees Fahrenheit, while Earth's average surface temperature from 1951 and 1980 was 57.2 degrees Fahrenheit.»

While he represents that this fault lies in inconsistency of the predictions of the models with a global average surface air temperature time serties, the fault truely lies in our inability to statistically test the projections of these models.

«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.

Over the past 60 years (1951 — 2010), the study finds that global average surface temperatures have warmed 0.6 °C, while in climate models, greenhouse gases caused between 0.6 and 1.2 °C surface warming.

Positive forcing at seasonal to inter-annual scales leads to an average global surface temperature drop from La Nina influence but recharging of OHC (longer term gain), while reduced forcing allows El Nino conditions and temporary peaks in global average temperature, and OHC reduction (longer term loss).

While the trend is not statistically significant, the central value is positive, meaning the average surface temperature has most likely warmed over this period.

On the other hand, if you removed all the Nitrogen from the terrestrial atmosphere (which is not a «greenhouse gas»), you'd readily get a Snowball Earth with a mile thick ice covering all the oceans while if you put twice as much Nitrogen there, average surface temperature would rise to 314 K (41 °C) with no additional «greenhouse effect» needed whatsoever.

ECS is the increase in the global annual mean surface temperature caused by an instantaneous doubling of the atmospheric concentration of CO2 relative to the pre-industrial level after the model relaxes to radiative equilibrium, while the TCR is the temperature increase averaged over 20 years centered on the time of doubling at a 1 % per year compounded increase.

While not directly comparable to surface temperature, the average temperature of the lower troposphere (TLT) from remotely sensed satellite data is also included.

Michaels also suggests that temperatures in 2015, while still being «the highest average surface temperature in the 160 - year global history since reliable records started being available,» had a «de minimis» effect on the global economy.

Specifically, the study found that» [d] uring much of last year's hurricane season, sea - surface temperatures across the tropical Atlantic between 10 and 20 degrees north... were a record 1.7 degrees F above the 1901 - 1970 average,» «global warming explained about 0.8 degrees F of this rise,» while» [a] ftereffects from the 2004 - 05 El Nino accounted for about 0.4 degrees F,» and a natural cycle in sea - surface temperatures «explained less than 0.2 degrees F of the rise.»

But now man knows that cloud cover mitigates warming from all sources (a negative feedback to Global Average Surface Temperature), while at the same time amplifying short term variations in solar radiation (a positive feedback to solar variability).

In the map at right, redder colors indicate where average monthly sea surface temperatures were warmer than the 1981 - 2010 average, while blue colors indicate where sea surface temperatures were cooler than average.

Comparing the average temperature for 1986 - 1990 with that for 1991 - 1996, the surface record (average of GISS, NCDC and HadCRUT) shows a warming of 0.04 °C, while the satellite record (average of RSS and UAH) shows a cooling of — 0.02 °C.

IMHO the emphasis on global average surface temperature in recent times, while understandable (if it really does rise 3 + K this century, the emphasis will have been justified) distracts from other issues that are just as important for local climate (which is what we all actually experience).
