I got annoyed when they started blaming Venus’s climate on CO2, if this were the case mars should be hotter than earth...

Venus is hot because of the lack of plate tectonics and lack of magnetic field which caused all the water to evaporate, and the hydrogen from the water to get stripped away by solar wind...

The only decent environmental story in the whole cosmos series was the one about the lead in the gasoline, which was actually a problem, but then they poisoned that story by trying to haphazardly equate it to the CO2 levels...

Lead is not a natural occurring substance in the air at the amounts it was when we started leading gasoline, CO2 has been around since basically forever and won’t kill a darn thing unless it is in HUGE quantities...

They also talked about earth’s climate like it was some fragile teeter totter, that if you pushed in one direction too far it would spiral out of control.... We have a surface covered by 75% water this acts a natural buffer to absorb a LOT of variations, that and they never seemed to take into the account of all the natural fires humans actually prevent that put CO2 into the air...

sloppy agenda based science...

Tyson is not a genius he's a sellout and an idiot. I have been tweeting him once a week asking him to find the Hot Spot. But with over a million followers he will never read it.

No smoking hot spot
1. The greenhouse signature is missing. We have been looking and measuring for years, and cannot find it.
Each possible cause of global warming has a different pattern of where in the planet the warming occurs first and the most. The signature of an increased greenhouse effect is a hot spot about 10km up in the atmosphere over the tropics. We have been measuring the atmosphere for decades using radiosondes: weather balloons with thermometers that radio back the temperature as the balloon ascends through the atmosphere. They show no hot spot. Whatsoever.
If there is no hot spot then an increased greenhouse effect is not the cause of global warming. So we know for sure that carbon emissions are not a significant cause of the global warming. If we had found the greenhouse signature then I would be an alarmist again.

He is also full of crap about the heat absorbing properties of CO2. That has been thoroughly debunked and it has been shown beyond doubt that most radiant heat is lost back into space. He must have told 15 baldfaced lies on last week's show.
