IF CO2 in the atmosphere could cause a measureable effect on radiation, it would interfere with radiant energy coming in as well as radiant energy going back out. The effects cancel each other out.
The Foremost Scientists have been wrong for decades - when I was in school in the 70's, the climate experts were issuing dire warnings of global cooling. They were wrong. So then they switched the story to warnings of global warming. Again, they were wrong. So now the narrative is "climate change"...a pretty vague term. Referring back to the OP, the Foremost Scientists that predicted the demise of the polar bears were......<drum roll>.....wrong.
Past changes of Earth's temperature - there's strong evidence that the Earth has gone thru something like 50 major temperature cycles over the last 5 million years. The Ice Age is a stark example of that. Humans were not present for any of at least the first 49 of them.
Personal Behavior of the GW Movement's Leaders, part 1 look at Al Gore's personal life choices. A mansion in TN that use 20x the national average for household energy. A second mansion in CA that is by the ocean (that is supposed to flood when the ice caps melt). Sells his TV network to a news organization funded by....<drum roll>.....oil money.
Personal Behavior of the GW Movement's Leaders, part 2 - at the Copenhagen climate conference, the worldwide delegates came in on so many private jets, that the planes had to be flown on to other airports to be parked. The delegates required so many limousines, that they had to be shipped in from neighboring countries. If these delegates truly believed that CO2 production was harming the Earth, they would have stayed home and had a video conference.
Sensitivity to Temperature Changes - the Foremost Scientists tell us that we need to be worried if the Earth's temp changes by 2 or 3 degrees. They predict floods, droughts, failed crops, etc. Does anything in your world fail because of a natural swing of 2-3 degrees? The summer average temperature in my area can be 15 degrees different for one year to the next. And the crops still grow, the wells still produce water...life goes on pretty much the same.
Follow the Money, part 1 - Foremost Scientists don't create commercial products, so they depend on grant money and foundations to put food on their family's tables. There is lots of money available for scientists trying to prove man-made global warming. There is virtually no grant money available for a scientist who wants to disprove the man-made global warming theory. If your family was hungry, which bandwagon would you be riding?
Follow the Money, part 2 - the UN wants to extort money from rich nations (that would be us) and give to third world countries to "help them cope with global warming". If the true problem was the amount of man-made CO2 being put into the atmosphere, the money should be spent developing low-CO2 processes for the big CO2 emitters (USA, China, India, etc.). Instead, what we have is a thinly-disguised socialist wealth redistribution scheme. Oh....and the UN will pay themselves handsomely before passing some of the money along.
University of East Anglia Climate Research Unit - a leading collector of climate temperature data. Their director Phil Jones had to step down after e-mails surfaced where he discussed with collegues that their data had been adjusted to "hide the decline" in world temperatures. And.....they had deleted all of the raw collected data, thus preventing any independent peer review...a clear violation of unbiased scientific method.
"The Debate is Over" insists Al Gore. Anybody who wants to declare a debate to be over after they have delivered their message (and before dissenting opinions can be shared) is signaling that they are on thin ice.
Humble apologies if the facts conflict with the liberal narrative.
