Radiation Transport in Clouds

The article details just how insignificant CO2 is as a factor in climate change, revealing that doubling the CO2 concentration from 400 ppm to 800 ppm – a 100% increase – hypothetically reduces radiative heat loss to space by just 1%.
It would take many decades to achieve such a ppm increase, plus there are not enough fossil fuels left over to make it happen.
Because CO2 has increased by only 50% since 1850 (280 ppm to 420 ppm), the CO2 total greenhouse effect regarding reducing upward IR radiation has thus far been in the range of tenths of a percentage point.
Such a small change in upward IR radiation, over 175 years, is not even detectable amid the noise of outgoing radiation measurement.
For example, the measured upward IR radiation has an error of about 33 W/m²
This negligible CO2 greenhouse effect is a calculated value for an atmosphere that is perpetually cloud-free.
As clouds are present 60 to 70% of the time, this clear-sky-only condition only occurs in an imaginary world – an atmosphere that doesn’t exist.
Compared to the CO2 role, the greenhouse effect of clouds is tens of times more influential.
To cool the Earth by a few percent, low cloud cover needs to increase by only a few percent.
During cloudy skies, there is warming, due to downward IR radiation from cloud bottoms at about 340 W/m^2
During clear skies, there is about 30% less warming, due to upward IR radiation at about 260 W/m^2, primarily from thermal emission of water vapor and CO2
If clouds increase from 60 to 65%, the upward IR radiation from earth surface would decrease by (0.40 - 0.35) x 260 = 13 W/m^2, and downward IR radiation (warming) from cloud bottoms would increase by (0.65 – 0.60) x 340 = 17 W/m^2, for a net warming increase of 30 W/m^2
Because cloud cover changes of much more than 1% routinely occur, such as during El Ninos, over time-scales of a few years, the role of CO2 within the greenhouse effect is insignificant, if not irrelevant.
Cloud cover changes are the only plausible explanation for most of the modest “secular” warming of the past two centuries. Together with ocean current fluctuations (see below URLs), cloud cover changes are also the only physical mechanism that could account for fluctuating temperature changes with time scales of a few years.
Based on fundamental physics, one should expect some warming from increasing CO2. But this warming will be too small to account for what has been observed.
Cloud cover changes provide the only rational explanation that does not violate basic physics.

El Nino Warming Events Occur Tens of Times Faster than CO2 Warming Effects
El Nino events typically produce temporary increases in global temperatures of 0.2 to 0.7 C, due to increased evaporation resulting in increased cloud cover of 2 to 5%, usually in less than 2 years.
The increase in low cloud cover reduces the net cooling effect of upward IR radiation.

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT
******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********
(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?
We have the facts on our side. We have the truth on our side. All we need now is YOU.
