The surface temperature increase that partially gave rise to concerns about global warming coincided with a move to tethered electronic measuring devices (um, I think that means thermometers) that forced the movement of many stations closer to buildings and developed areas, causing warming that may not have been corrected for.

Global warming does not mean no winter, it means winter start later, summer hotter, as Gary Peters said «The global average surface temperature has risen between 0.6 °C and 0.7 °C since the start of the twentieth century, and the rate of increase since 1976 has been approximately three times faster than the century - scale trend.»

In the standards for middle school, for example, one of the core ideas is that «human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth's mean surface temperature («global warming»).»

This means that every 2 degree potential rise in temperature of the surface layer causes an 8 fold rise in the amount of water vapor release hence buckets more clouds and massive albedo reflection keeping the temperature from riding.

This means that the «pause,» or whatever you want to call it, in the rise of global surface temperatures is even more significant than it is generally taken to be, because whatever is the reason behind it, it is not only acting to slow the rise from greenhouse gas emissions but also the added rise from changes in aerosol emissions.

What I mean is simply that we have as much actual empirical evidence for the existence of even one unicorn in this world as we have for the basic AGW claim that more CO2 in the atmosphere can, will and does cause a net rise in Earth's average global surface temperature, i.e. NONE whatsoever!

We might expect «global warming» (i.e., an increase in average surface air temperatures over a few decades) to lead to a rise in global mean sea levels.

Second, if «the pause» in the rise in mean surface temperatures turned out not to be temporary, it would be a good thing (although continuation of increased magnitude of other impacts would be, obviously, troubling).

What can «go away» might be a rising trend in global mean of surface temperatures — most likely on a temporary basis.

The significance of straightness is that this is what Arrhenius calculated as the expected behavior of global mean surface temperature with rising CO2.

This means that if the surface temperature is constant and energy is slowly transferring into the water column all the way to the sea floor, the ocean will keep expanding and sea level will continue rising.

Global mean surface temperature might well induce sea level rise but even there, it is not a singular factor and SLR is not rising a a calamitous rate as seen in the movies.

During the past century land use change has given rise to regional changes in the local surface climatology, particularly the mean and variability of near surface temperature (Pitman et al, 2012).

As we all here know (but most in the general public who are reading Mr. Rose's article probably do not), the «cool phase» is named so because of what it means for sea surface temperatures primarily along the North American west coast.

Use it for LW and increased «Forcing» REDUCES net surface IR flux (the vector sum of irradiances), meaning temperature has to rise to keep convection plus radiation constant.

The team hopes that actions to tackle rising global surface temperatures such as targets on reducing greenhouse gas emissions will mean better news for Europe's weather.

The NAO's prominent upward trend from the 1950s to the 1990s caused large regional changes in air temperature, precipitation, wind and storminess, with accompanying impacts on marine and terrestrial ecosystems, and contributed to the accelerated rise in global mean surface temperature (e.g., Hurrell 1996; Ottersen et al. 2001; Thompson et al. 2000; Visbeck et al. 2003; Stenseth et al. 2003).

However the consensus of those who have studied the question most closely is that the global mean surface temperature is rising at a rate that will bring it to between 2 and 4 degrees hotter than today.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

The model calculates the path of atmospheric CO2 and other GHG concentrations, global mean surface temperature, and mean sea level rise resulting from these emissions.

Vaughan writes «However the consensus of those who have studied the question most closely is that the global mean surface temperature is rising at a rate that will bring it to between 2 and 4 degrees hotter than today.»

The event could mean an end to the relative pause in the rise of land surface temperatures, with excess heat no longer trapped by the world's oceans and instead ramping up in the atmosphere.

This means that the global mean sea surface temperature mainly controls the CO2 content in the atmosphere; when the mean sea surface temperature is rising, the CO2 content in the atmosphere is increasing.

Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth's mean surface temperature (global warming).

While surface temperatures have generally remained fairly close to the multi-model mean in the past, the recent pause threatens to cause surface temperatures to fall below the 5th percentile of models in the next year or two if temperatures do not rise.

Their conclusion was that after 50 years with no greenhouse gases the Earth's albedo would have risen from today's 0.293 to 0.418, and that mean surface temperature would have fallen from 288 K to 252 K, a drop of 36 K, of which 9 K, they imagined, was the loss of directly - forced warming from the non-condensing greenhouse gases and the remaining 27 K was the loss of feedback response to that directly - forced warming.

In contrast, since the mid 1970's the strong La Ninas have peaked closer to NH winter during a period when global mean surface air temperatures have overall been rising slightly.

However, ocean temperatures have warmed almost everywhere on the planet, with 0.5 ºC being the global mean rise of sea surface temperature, hence Trenberth's reasonable estimate that this much is the contribution from global forcings like CO2.

From 1993 to 2012, the «global mean surface temperature... rose at a rate of 0.14 ± 0.06 °C per decade,» and the observed warming over the last 15 years of the period was, «not significantly different from zero.»

(It is frequently forgotten or overlooked in discussions of global mean temperature that temperatures over land rise much more than temperatures over ocean — and ocean, of course, occupies roughly 70 % of the world's surface.
