cleaner air has effectively boosted the total warming from carbon dioxide emitted over the same time by anywhere from 15% to 50%...

[Fred Bloggs]

This has been made quite clear for the past 20 years, spawned by the work of an Israeli scientist looking at 50 year records of agricultural pan evaporation data. German climate researchers are finally using real satellite data and putting some solid numbers to it.

\"Whatever the exact contribution, it is sure to grow as air quality continues to improve around the world.

Water (H2O) in the gaseous state is the only greenhouse gas due to its high heat of phase shift fluid - gas

We need condensation nuclei to turn microdroplets of water vapor into raindrops

So we need dust from industrial chimneys to make it rain

I joined project by US EPA 40 years ago to study emissions from industrial chimneys,
by reading data from monitoring stations and studying the wind rose to draw pollution charts and maps.

We were highly successful to eliminate 10,000 industrial chimneys in Europe
to make \"Air Clean\"

The most abundant greenhouse gases in Earth\'s atmosphere, listed in decreasing order of average global mole fraction, are:[14][15]

Water vapor (H
2O)
Carbon dioxide (CO
2)
Methane (CH
4)
Nitrous oxide (N
2O)
Ozone (O
3)
Chlorofluorocarbons (CFCs and HCFCs)
Hydrofluorocarbons (HFCs)
Perfluorocarbons (CF

Role of water vapor
Increasing water vapor in the stratosphere at Boulder, Colorado

Water vapor accounts for the largest percentage of the greenhouse effect, between 36% and 66% for clear sky conditions and between 66% and 85% when including clouds.[21] Water vapor concentrations fluctuate regionally, but human activity does not directly affect water vapor concentrations except at local scales, such as near irrigated fields. Indirectly, human activity that increases global temperatures will increase water vapor concentrations, a process known as water vapor feedback.[22] The atmospheric concentration of vapor is highly variable and depends largely on temperature, from less than 0.01% in extremely cold regions up to 3% by mass in saturated air at about 32 °C.[23] (See Relative humidity#Other important facts.)

The average residence time of a water molecule in the atmosphere is only about nine days, compared to years or centuries for other greenhouse gases such as CH
4 and CO2.[24] Water vapor responds to and amplifies effects of the other greenhouse gases. The Clausius–Clapeyron relation establishes that more water vapor will be present per unit volume at elevated temperatures. This and other basic principles indicate that warming associated with increased concentrations of the other greenhouse gases also will increase the concentration of water vapor (assuming that the relative humidity remains approximately constant; modeling and observational studies find that this is indeed so). Because water vapor is a greenhouse gas, this results in further warming and so is a \"positive feedback\" that amplifies the original warming.. Eventually other earth processes[which?] offset these positive feedbacks, stabilizing the global temperature at a new equilibrium and preventing the loss of Earth\'s water through a Venus-like runaway greenhouse effect.[22]
Contribution of clouds to Earth\'s greenhouse effect

The major non-gas contributor to Earth\'s greenhouse effect, clouds, also absorb and emit infrared radiation and thus have an effect on greenhouse gas radiative properties. Clouds are water droplets or ice crystals suspended in the atmosphere.[25][21]

China mostly burns it\'s own coal. Australia does sell it some but China imports less than 10% of the coal it burns.

If our government stopped digging it up and selling it to China we\'d probably find ourselves with a new government. The US attitude to \"banana republics\" is pretty representative of what big economies do to smaller economies who don\'t feel like playing along.

> As Germany ramps up their coal power plants, maybe they should remove the stack scrubbers.

Why? Germany isn\'t \"ramping up\" their coal plants - they are just burning more coal than natural gas, because they don\'t like buying natural gas from an increasingly war-like Russia. They will ramp them down again when they have installed more renewable energy generation (which produce cheaper power that burning fossil carbon, but takes time and capital to manufacture and install).

Africa is getting power any way it can. Solar cells produce cheaper power than any other source, and lend themselves to local production, though you do need batteries. Setting up a nation-wide grid is an unnecessary extravagance.

John Larkin is stuck in some kind of intellectual time warp where the only way to get energy involves burning fossil carbon - probably because he believes the climate change denial propaganda he seems to read, and post links to here from time to time. Maybe he has ambitions of being crowned Mr. Gullible?

The sensed temperatures accurately record climate changes that affect crops and forests.
It certainly isn\'t an artifact of runway proximity.

White paint isn\'t a fix.

Yeah, mainly \'the records\' reported in news accounts are from well-understood weather
monitoring available to the public, often sited at airports. A neighbor posts his weather station
results, too (but I\'m guessing the local newspaper doesn\'t consult that record).

Albedo effect matters

----

Measure of the reflectivity of a surface
Albedo is a measure of the reflectivity of a surface. The albedo effect when applied to the Earth is a measure of how much of the Sun\'s energy is reflected back into space. Overall, the Earth\'s albedo has a cooling effect. (The term ‘albedo’ is derived from the Latin for ‘whiteness’).
The albedo effect and global warming
skepticalscience.com/earth-albedo-effect.htm
skepticalscience.com/earth-albedo-effect.htm



What is the albedo effect on land?
The albedo effect on land. Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo).

:What is the albedo effect on land?
What is the albedo of a dark object in space?
Albedo Effect Astronomers define the reflectivity of an object in space using a term called albedo. This is the amount of electromagnetic radiation that reflects away, compared to the amount that gets absorbed. A perfectly reflective surface would get an albedo score of 1, while a completely dark object would have an albedo of 0.

What is the relationship between illumination and albedo?
Albedo is not directly dependent on illumination because changing the amount of incoming light proportionally changes the amount of reflected light, except in circumstances where a change in illumination induces a change in the Earth\'s surface at that location (e. g. through melting of reflective ice).

During nighttime, albedo inhibits the shedding of heat by radiation into the black night sky,

White surfaces don\'t get that hot that they need to shed any heat at night...white surfaces work. You don\'t think so? Paint your vinyl siding black and see how long it lasts.

The error here, is you assume it was heat stored in the object, not in the ambient air bathing all
the objects in the vicinity, that was to be \'shed\' at night. The effect of an albedo
enhancement is to reduce BOTH the emission and absorption of heat by radiation; that\'s why

the objects in the vicinity, that was to be \'shed\' at night. The effect of an albedo
enhancement is to reduce BOTH the emission and absorption of heat by radiation; that\'s why
thermos flasks are silvered.

Air doesn\'t have much thermal capacity and doesn\'t have much heat to exchange with much more thermally massive materials like water and masonry.

Urban Heat: Can White Roofs Help Cool World’s Warming Cities?

You are right about radiation, air isn\'t a very good conductor either, especially when it\'s not moving.

But a whole diurnal cycle (day) without breeze isn\'t normal. Air, 15 lbs per square inch, and soil, and other objects,
have significant heat capacity, and readily exchange heat; it isn\'t surface wind that radiates to
the sky, but objects. The breeze in my window does get cooler at night; there\'s plenty of movement of
heat (by convection) and fresh bits of air adjacent to objects do pick up heat, by conduction, over
very small distances (conductivity of air-to-air doesn\'t dominate the effect).

Radiation of heat into the sky is exactly equal to insolation heat inflow, at the steady-state temperature
we deem \'temperate\'. One cannot ignore either of the two equal effects. The \'albedo-works\' argument
has that flaw.

Of course, quite a bit of the heat being radiated into the sky is being radiated from a layer of gas fairly high in the sky - the effective ration altitude for a given wavelength - where photons of that particular wavelength finally have an even chance to make it out into the universe, rather than being absorbed by some greenhouse gas or other and getting re-radiated in some arbitrary direction. This is how greenhouse gases warm the surface of the planet.

>One cannot ignore either of the two equal effects. The \'albedo-works\' argument has that flaw.

Albedo is frequently wavelength dependent, which further complicates the argument. Snow and ice are very reflective at visible wavelengths, less so in the near infra-red.
