Carl Sagan describes climate change 40 years ago

@13:00 “We are at a very dangerous moment in human history. We have weapons of mass destruction, we are in the process of inadvertently altering our climate, exhaustion of fossil fuels, all kinds of problems come with technology. We are not certain that we will survive this period of what I like to call technological adolescence.”

Great words from a smart man in public life so long ago.  And we didn’t listen.
