Every few years I like to just sit down and watch Cosmos, the PBS series from the early 80's by Carl Sagan. I am in one of those periods now and tonight I watched 2 episodes one of which was titled Heaven and Hell. I want to share with you something from that episode, a 27 year old warning from Dr. Sagan:

. . . at the same time we are releasing vast quantities of carbon dioxide increasing the greenhouse effect. The Earth need not resemble Venus very closely for it to become barren and lifeless. It may not take much to destabilize the Earth's climate, to convert this heaven - our only home in the Cosmos - into a kind of hell.

Of course if you have seen Al Gore's An Inconvenient Truth you would know that scientists had these concerns more than a decade before Cosmos appeared. And yet we continue on, a huge chunk of the population of this country blindly listening to a corrupt administration concerned not with the welfare of the people but with the short term profits of their corporate enablers.
