In the tropics and subtropics, CO2 a weak photon absorber, plays no measurable role, because, near the surface, it is outnumbered by at least seventy to one by water vapor, a strong photon absorber.
Plus, water vapor, 18, is lighter than CO2, 44, and air, 29, so it condenses into clouds at about 2000 meter elevation, which, with prevailing winds, are transported to northern latitudes, to areas underserved by the sun, especially during winter.
That means the water vapor and clouds we see up north comes from faraway places, because up north there is not enough energy to evaporate the water, which often lies on the ground as snow and ice.
But, even up north, near the surface, CO2 plays no measurable role, because water vapor outnumbers it at least 20 to one.
CO2 begins to play a measurable role when the presence of water vapor is lower, say 3 to 1, which is above the clouds.
However, above the clouds it is colder, and any photons emitted there would have longer wavelengths beyond the CO2 15 micrometer absorption window, but water vapor would absorb these photons, because it has a much wider window starting at about 15 micrometer.
With lower temperatures at higher elevations, the kinetic energy of molecules decreases, per gas laws.
KE = 3/2 RT = 3/2 x 8.314 J / (mol K)
At higher elevations, density is less. There are fewer collisions, because molecules are further apart.No matter the temperature, photons (vibrating packages of energy at a wavelength) move at the speed of light, which is many orders of magnitude greater than the speed of molecules.
No liberal arts journalists would ever write this, because it is way above their heads. They stick to talking points provided by self-serving elite $stakeholders and their associates

Offshore Wind, a proposal destined to implode upon itself. Are you ready for the bailouts coming?

Frank,Do not forget this paragraph in all such postingsStatic testing is wholly inadequate for a rotor blade that sees variable torsion and variable bending forces WITH EACH TURN, because wind speeds significantly vary from side to side and top to bottom of the 800-ft diameter circle scribed by the rotor thousands of times per day.During strong winds, say 30 to 40 miles/h, those dynamic forces are very high, and can only be measured by fully instrumenting a blade on a mast in the North Sea, for at least a year to cover all weather conditions.

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.
