Summary

What makes Iceland so warm despite its high latitude? What powers everything from glaciers to geysers? How are the aurora connected to volcanoes? I discuss these questions and more in today’s Ask a Spaceman! A very special edition recorded in Vik, Iceland, where I gave a special talk on the forces fighting for balance underneath and above the island.

0:00.0	This is obviously not going to be a normal episode of Ask a Spaceman.
0:17.6	I gave a talk while I was in Iceland with the Astro Taurus and I wasn't planning
0:24.2	on giving a talk. I was just going to do an open-ended Q&A for a while and it was going to be
0:29.1	lots of fun and spontaneous and sparkling and bubbly, you know, all the usual science and
0:34.1	goodness. And it turned how we got completely snowed in, where we were locked into
0:39.9	our hotel. All the roads were closed for two and a half days. And so I had to come up with some
0:44.8	extra content. So the next episode of Ask a Spaceman is going to be that Q&A. This episode is going to
0:52.2	be a talk I made up on the spot about one hour before I gave it.
0:59.2	And the subject of the talk is the title of the episode, Why Is Iceland So Warm?
1:04.6	And I had this realization a couple days into the trip as we were looking at all the beautiful vistas and
1:12.7	the Aurora, and if you didn't go on the trip, you really missed it. It was pretty awesome.
1:17.6	I had an epiphany. I had one of those, like, a mild, a mild eureka moment where a lot of things
1:26.8	clicked into place, that a lot of the things that I were seeing,
1:32.2	the sights and the sounds and just the visual treat of that country,
1:37.9	so many things clicked into place surrounding a common theme.
1:43.3	And I'm going to explore that theme in the talk. But the other important
1:47.5	thing that I realized is that you need to go to patreon.com slash p.m. Sartre because I didn't mention it
1:53.0	during the talk. So here is the pitch. Patreon is how you keep this show going. And special thanks to
1:58.8	Robert R. Justin G. Matthew K, Kevin O, Justin R,
2:02.4	Chris C, and Helga B for all your generous contributions at patreon.com slash p.m. Sutter.
2:09.5	And this is Ask a Spaceman. You can always send questions to Ask a Spaceman at Gmail.com.
2:16.9	Go to Ask aSpaceman.com. Use hashtag Ask a Spaceman at gmail.com. Go to askaspaceman.com. Use hashtag Ask a Spaceman on Twitter and
