Carl Sagan on climate change at the Emerging Issues Forum (1990)

Welcome to the first issue of The Cassandra Dispatch!
The simple idea behind this newsletter is that I pick and send one video every two weeks that features a speech or discussion by a great science communicator like Carl Sagan, Richard Dawkins and others. The “accessible” part is important - you won’t need any specific background, just an open mind and curiosity.

Without further ado, here’s the first video featuring the amazing Dr Carl Sagan.

In this hour-long keynote speech Dr. Sagan talks about why global warming is dangerous and what we can do about it. It’s striking that 32 years ago, it was already crystal clear what mitigation measures we needed to take. It’s saddening that humanity failed to take action more swiftly.
