A blanket around the Earth
Most climate scientists agree the main cause of the current global warming trend is human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as feedback.
most climate scientists do NOT agree.
you make NO points by using the logical fallacy of appeal to authority
think for your self...analyze the facts ...
common sense, and a few facts, will expose that idea to be wrong.
CO2 is only effective for a very narrow 'window' of the electro magnetic spectrum...once that window is 'dirty'...it's done.
the real problem is that we don't have ENOUGH CO2 in the atmosphere . CO2 is plant food...the plants are starving. That's the reason greenhouse operators BOOST the CO2 to 1000ppm or more. Plants do MUCH better with more food.
