The researchers found that on windy nights it wasn't possible to measure the cooling effects of the green spaces beyond their boundaries as there was too much turbulent mixing of the air; but on calm warm nights they estimate that a network of green spaces of around 3 - 5 hectares each situated 100 - 150 m apart would provide comprehensive cooling for a city with a climate and characteristics similar to London.

It's now commonplace to talk about global warming and carbon footprints, so much so that it's easy to forget that until quite recently few thought it was even possible that the actions of our species could have a potentially catastrophic effect on the Earth's climate.

What is alarming is that the volume of water and the extent and rapidity of its movement is suprisingly much greater than previously believed, and that a possible, perhaps likely, effect of this on ice sheet dynamics is to make the ice sheets less stable and more likely to respond more quickly to global warming than previously expected.

Before allowing the temperature to respond, we can consider the forcing at the tropopause (TRPP) and at TOA, both reductions in net upward fluxes (though at TOA, the net upward LW flux is simply the OLR); my point is that even without direct solar heating above the tropopause, the forcing at TOA can be less than the forcing at TRPP (as explained in detail for CO2 in my 348, but in general, it is possible to bring the net upward flux at TRPP toward zero but even with saturation at TOA, the nonzero skin temperature requires some nonzero net upward flux to remain — now it just depends on what the net fluxes were before we made the changes, and whether the proportionality of forcings at TRPP and TOA is similar if the effect has not approached saturation at TRPP); the forcing at TRPP is the forcing on the surface + troposphere, which they must warm up to balance, while the forcing difference between TOA and TRPP is the forcing on the stratosphere; if the forcing at TRPP is larger than at TOA, the stratosphere must cool, reducing outward fluxes from the stratosphere by the same total amount as the difference in forcings between TRPP and TOA.

Building cities along coastlines as we have throughout our so - far short modern history, short though it has been from the standpoint of our climate history, should be recognized as the kind of short term planning that has gotten us into this trouble whether it happens now or a few decades or centuries down the road, and this concern over atmoshperic warming is just one of a multitude of possible planet - affecting scenarios that could have devastating effects on our world's societies.

Warming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux aWarming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux awarming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux awarming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux at TOA).

Indeed, a portion of that small linear trend difference might be due to human CO2 emissions; or, then again, it might be due to the vast urbanization effect over the last 60 + years; or due to the large deforestation that's taken place; or, maybe it's entirely due to the serial fabrication of global warming by the world's climate agencies; or it's even possible that the post-1950 warming was entirely a natural phenomenon - the same as the prior 64 - year period experience.

Meanwhile, the logarithmic effect of CO2 is excellent «concession» to make in the rhetorical sense, since it concedes the obvious state of our knowledge about the effects of CO2, while at the same time providing us with the solid argument that even if we double atmospheric CO2 levels from 400ppm to 800 ppm over the next 100 years the largest amount of warming possible — assuming all else remains the same and Gaia has no homeostasis negative feedback systems which tend to moderate any runaway trends — is 1.2 c.

Most of the «future» effect is already «dialed in», it is the observation of delayed effect that is being given «regard» as a «greenhouse issue», even as the «greenhouse effect» is seen as not possible, or that «greenhouse warming amplification» is not evidenced within possible surface incident energy (as Photons).

If these plumes of warm air operated in the same way during the last glaciation as they do know then they would make short work of ice sheets that were hanging around because of the albedo effect, this is possible because not all the northern hemisphere mid latitude land surface was covered with ice throughout the period of glaciation and might explain why glaciations terminate quickly

The reasons for that are many: the timid language of scientific probabilities, which the climatologist James Hansen once called «scientific reticence» in a paper chastising scientists for editing their own observations so conscientiously that they failed to communicate how dire the threat really was; the fact that the country is dominated by a group of technocrats who believe any problem can be solved and an opposing culture that doesn't even see warming as a problem worth addressing; the way that climate denialism has made scientists even more cautious in offering speculative warnings; the simple speed of change and, also, its slowness, such that we are only seeing effects now of warming from decades past; our uncertainty about uncertainty, which the climate writer Naomi Oreskes in particular has suggested stops us from preparing as though anything worse than a median outcome were even possible; the way we assume climate change will hit hardest elsewhere, not everywhere; the smallness (two degrees) and largeness (1.8 trillion tons) and abstractness (400 parts per million) of the numbers; the discomfort of considering a problem that is very difficult, if not impossible, to solve; the altogether incomprehensible scale of that problem, which amounts to the prospect of our own annihilation; simple fear.
