They heard of all of this and all they heard was CO². All they took away was WE HAVE to FIX THIS. Government is the process of finding the most stupid conclusion and running as far as they can with it.

Lovey speaker though, no matter what he is saying!

Yep, unless China and everyone else does it, there will be no effect.

I used to think this guy was really smart. Now I realize he was just full of intelligence. CO2 has nothing to do with venues high temperature...Its the extreme atmospheric pressure that causes the high temperatures.

he says venus has a high albido so where does the infrared radiation come from ? mars has the same co2 content as venus but is cold.

Prof. Sagan once remarked, "Extraordinary claims require extraordinary evidence." How climate change may shape the world in the centuries to come utm_source=Editors_Picks&utm_medium=email&utm_campaign=editorspicks112121

Sagan was one of the biggest frauds of 20th century "science." His Phd thesis was on the greenhouse effect and Venus. It was later thoroughly debunked, and he actually had to basically repudiate his own paper ( reluctantly ). Unfortunately, his idea of a "runaway greenhouse effect" is STILL with us today, and still widely believed. SETI - another expensive boondoggle promoted by Sagan. The Search for Extraterrestrial Intelligence was based upon a pure fiction known as the "Drake Equation" which basically is a whole series of "SWAGS" aka "Scientific Wild-Assed Guesses." He was VERY political - and had far-left viewpoints, hated guns, and assumed that government should subsidize any damn-fool project that called itself "science."

The effect of the 'greenhouse gas' water vapor seems to have escaped his observations. This was just a few years after the media was touting a new ice age. This actually just reveals the inherent fallacy of his comments. Nothing major has happened as he suggested would probably occur. Hindsight being 20/20. At least, for those who can see at all.

Carl Sagan was a true scientist and would participate in any scientific debate. His views at that time were heavily influenced by that time. IMO, if Carl would be around in these days, I'm pretty sure he would express a different POV.
