The global cooling argument is hitting hard again right now due to the recent chill.

Global climate models have successfully predicted the rise in temperature as greenhouse gases increased, the cooling of the stratosphere as the troposphere warmed, polar amplification due the ice - albedo effect and other effects, greater increase in nighttime than in daytime temperatures, and the magnitude and duration of the cooling from the eruption of Mount Pinatubo.

The climate models are still absolutely unable to discern either the amount or rate of global warming / cooling that is due to natural forces.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

In 1974 when the Club of Rome formulated it, the consensus was that global cooling (due to dust and pollution from natural volcanic eruptions and from industry) was screening out sunlight, and we were in for runaway glaciation and a new ice age.

If the surface pressure distribution begins to shift to a more meridional / equatorward pattern as it did around 2000 then if previously it was in a poleward / zonal mode it is clear that warming will have ceased and cooling has begun due to more global cloudiness and less solar energy getting into the oceans.

There, it is written that the absorption of surface radiation by CO2 is saturated and that the decrease in the global outgoing longwave emission due to more CO2 in the air is only due to the «higher and cooler» emission level of tropospheric CO2 radiating to the cosmos.

I think it is time for a general update due to subsequent developments (especially the current 2 year global cooling trend and a quieter sun with cooling oceans after an 8 year temperature plateau which tends to show that my point about solar and oceanic influences on global temperatures has some merit) and the fact that I can make the essential points more simply by condensing them into a series of bullet points as follows:

1974: Scientists at National Academy of Science propose evacuation of 6 million from homes due to global cooling drought conditions

Randomly mentioning the stratosphere cooling is a far, far, FAR cry from even approaching the viscinity of a claim you believe the earth has trapped: for years — so much heat from the sun that the stratosphere stopped being warmed due to the thermal disconnect at the tropopause — that IS what Magic Gas's claim boils down to — that the lower atmosphere is somehow «hiding» such massive amounts of energy the fact you think it's credible on it's face is aNOTHer indicator which end of the global warming argument pool, you're at, Don.

It will become increasingly clear in the next few years that global temperatures have not warmed significantly since about 1980, and the small amount of observed atmospheric warming was primarily due to the natural recovery after the temporary cooling effect of two major volcanoes, El Chichon in 1982 and Pinatubo in 1991 +.

Using the same assumptions at Christy and McNider 2017 (~ all changes are due to increasing atm.CO2), I estimated TCS equals MINUS ~ 1C / (2xCO2) for the global cooling period from 1940 to 1977, ~ equal but opposite sign to the PLUS 1.1 C calculated by Christy and McNider for 1979 to 2017.5.

Perhaps it's due to a smaller global energy imbalance due to more aerosol cooling and lower solar activity offsetting more of the greenhouse gas - caused warming.

In other words, the slowed surface warming isn't a result of a smaller global energy imbalance due to factors like increased cooling from human aerosol emissions.

C / If global temperatures decline and through stupidity after some way is found to limit and reduce CO2, global CO2 levels are reduced through the efforts of activist climate science establishment then the world will go hungry as the world's farmers will not be able to grow enough food as both yields and cropped area are reduced due to cooler or colder temperatures and reduced amounts of that essential plant food, CO2 other wise known as that planet destroying «carbon».
