Master of Catastrophe
Paleontologist Peter Ward, professor of biology at the University of Washington and an expert on mass extinction events, stopped by Big Think today to discuss nothing less than the fate of the planet. How is it looking? Not too rosy, says Ward, who has just returned from measuring CO2 levels in Antarctica.
Ward's interview will be posted as part of our upcoming series on plausible doomsday scenarios, called "How the World Might Really End." He offered not one but many juicy scenarios to choose from: greenhouse-induced flooding and sulphur poisoning, an asteroid impact, the eventual freezing of the planet's core...
Ward's newest book, "The Medea Hypothesis" (which posits that we're not the only self-destructive species on Earth), is due out in March.

- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
