Originally posted by EladarWell DUH, of course the sun is ultimately responsible for heating of the earth and cooling if it drops energy transfer but CO2 has the ability to transmit visible light where it is mainly transparent but reflects IR so when the visible light from the sun heats up the earth the IR built up by such heating is retained and ending up heating. This has been born out in hundreds of observations of fossil records, ice core direct measure of CO2 from hundreds of thousands of years ago. The CO2 levels are higher than they have been for more than a half million years and that rise is 100 percent due to burning fossil fuels. This rise in temps are also causing methane to be released from the tundra which has until now been frozen and now thawing out and releasing methane into the atmosphere where it is 20 times more dangerous as a greenhouse gas than CO2 which can have the effect of tipping us over very quickly into a world wide disaster climate wise. People like you and your ilk are doing the world a vast disservice by denying it. You are like the holocaust deniers. I wonder if you also think the moon landing was a hoax too.
So even the bbc is saying that the sun is the main influence on the heating and cooling of the earth.
