No and I don't claim to know all the answers, I'd like to know why the Earth turned into a snowball from pole to equator .7 billion years ago but from 1.5 to .7 billion, when our star was even weaker, it did not and despite a weaker sun things were much warmer. Apparently the climate machine is a bit more complicated than what some would have us believe. > Several posts up, you obviously did not know about the sun warming > issue. > BULLSHIT! I would be willing to bet money that I know more about the evolution of stars, both on and off the main sequence, than you do, and probably one hell of a lot more. >>> You keep throwing out eratic graphs....you do know they are provided >>> by climate science? >>> >> > >> So you think climate scientists are putting out "eratic graphs" but >> nevertheless based on what they say you think the human race should be >> forced to be put on a starvation energy budget that will impoverish the >> world and kill billions of people.
