Welcome to Scientific American’s Science Talk, posted on July 21, 2019. I’m Steve Mirsky. And while much of the lower 48 is sweltering, things are somewhat cooler in Alaska. Not as cool as they should be, but anyway. Back in January, we brought you part 1 of a report from the ice fields near Juneau. Part 2 is coming up. But I’m gonna play part 1 again first for anyone who missed it or wants to get a refresher. And the beauty of podcasts is: if you wanna jump ahead to part 2, just skip ahead 10 minutes.

PART 1: Elizabeth Case is a graduate student studying glaciology at the Lamont-Doherty Earth Observatory, part of Columbia University’s Earth Institute. In the summer of 2018 she headed out onto the ice fields near Juneau, along with her mentor, Columbia earth scientist Jonny Kingslake, as part of the Juneau Icefield Research Program, or JIRP. She brought her trusty recorder and sent back audio. She mentions Seth Campbell, he’s at the University of Maine and is the director of JIRP. She also brings up Bradley Markle, who’s a postdoc at Caltech, and Wilson Clayton, formerly an environmental engineer and visiting faculty member at JIRP. Here’s part 1 of her story of doing science on the ice ... on the ice. REST OF PART 1

Here's Part 2

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
