the whole venus argument is new low even for climate hysterics. mars atmosphere is 95% CO2 so the point remains valid... that is if anything can be valid by such a truly ludicrous argument
You can argue the Venus thing is a new low, but be factual.
No, it's not valid. The atmosphere of Mars:
Quote:The atmosphere of Mars is less than 1% of Earth’s, so it does not protect the planet from the Sun’s radiation nor does it do much to retain heat at the surface.
Where as Venus is:
Quote:Three words: runaway greenhouse effect. In many ways, Venus is a virtual twin of Earth. It has a similar size, mass and gravity as well as internal composition. But the one big difference is that Venus has a much thicker atmosphere. If you could stand on the surface of Venus, you would experience 93 times the atmospheric pressure we experience here on Earth; you’d have to dive down 1 km beneath the surface of the ocean to experience that kind of pressure. Furthermore, that atmosphere is made up almost entirely of carbon dioxide.
See, there is a big difference and the reason Venus is hot enough to melt lead on it's surface is because of it's atmosphere, not 50 million miles.
