I mentioned yesterday that I was pivoting back to the climate crisis in a major way.
As part of that pivot, I’ll be talking with Jay Ackroyd this evening for a full hour on his show Virtually Speaking.
The link at BlogTalkRadio works for listening live and listening later. In addition, Virtually Speaking is available as an iTunes podcast. I’ve been a subscriber for years and find the selection surprisingly broad. (For example, this week’s Virtually Speaking Science show covered … dinosaurs, entirely by coincidence.)
What we’ll be talking about
Tonight the hour will cover the basics of the climate crisis story from a lay perspective. We’ll look at life on earth and the mass-extinction events that mark the end of million-year-long geological eras (for example, the one that ended when the dinos died).
We’ll also take a look at earth temperatures across the long sweep, from 500 million years ago until now, and note that only recently has the climate been stable enough for man to move from hunter-gatherer to “civilized” with settled communities and farming. We’ll have a chart that shows that to a remarkable degree.
Why do the mass extinctions matter? Because according to James Hansen, a NASA scientist and one of the leading researchers in this field, we’re facing another mass-extinction event very soon, one a massive scale.
Our discussion of earth’s past will include material from this post:
Information about James Hansen’s prediction is available here (scroll down for the mass extinction quote):
And we’ll take a look at where we’re headed and how long will it take to get there. My thoughts on that, after studying climate literature for most of last year, are here:
Bottom line, we do have time, but not a ton of it. I’ll attempt to detail what life on earth looks like in 2100 if we fail, and what the world looks like if we succeed.
The road to success is clear — there’s only one path. I’ll be discussing that with Jay as well. Please tune in if you can. Thanks!
