How Carl Sagan Predicted Nuclear Winter

The video celebrates Carl Sagan's contributions to space science, highlighting his work on tholins, which are complex organic molecules formed in space. Sagan's experiments on Titan's atmosphere suggested the presence of amino acids, hinting at potential life. He also developed the nuclear winter concept, warning of its catastrophic effects. The video concludes with acknowledgments to supporters.
