Whenever I hear them say “powerful greenhouse gas” you know that ANYTHING that follows is total BS. There is only ONE greenhouse of any consequence, and it is very, very powerful. So powerful, that your weatherman uses it to PREDICT the weather. Water Vapor, is many, many times more prevalent than CO2, and it is a greenhouse gas. Changes in Water Vapor concentration can change the temperature in a matter of minutes.
Most of these “scientists” don’t even know what relative humidity is, much less that 3/4 of the Earth is covered with oceans thousands of feet deep.
When my weatherman tells me the CO2 number, to predict tomorrow’s weather, get back to me.
