  1. Mars atmosphere mostly CO2 and it averages -81, so let's add more CO2 as that will heat it up lol. Great except for that greenhouse gas nonsense, CO2 on Earth FOLLOWS temperature change, it doesn't LEAD it. The actual Earth history proves this or Mars should be nice and warm now. This proves that it's not CO2 but atmospheric pressure that has more effect on climate as he unknowingly suggest by his assertion that increasing the thickness of the atmosphere with CO2 would increase temp. It's the thickening effect the gas whatever it may be, that is the driver of climate not the specific gas that causes it. Go to Jupiter and see the effect atmospheric pressure has on temperature. Earth has been in an Ice Age with 4000ppm CO2, ten times the level of today. CO2 levels have been falling for last 70 million years as temp has stayed reality constant, it's only the last few decades we've seen any rise and that's minuscule in geologic terms, yet the alarmists claim this is rock solid proof as they ignore the previous billions of years. So stupid it's laughable really.
