Hearing & Hearing Aids

Starting this week, the FDA has approved the sale of over-the-counter hearing aids.  In light of that, in today’s edition of How on Earth, we play an Encore Feature from February 2020 of an interview we did with David Owen about his book, Volume Control, in which he explores the surprising science of hearing and the remarkable technologies that can help us hear better.

What’s New in Climate?

In this week’s How on Earth, we look at 3 aspects of climate change: its role in disease incidence and transmission; some effects of the new climate change legislation; and how ‘micro-forests’ can mitigate temperature and water loss. The latter comes from an interview with author Hannah Lewis and her book Mini-Forest Revolution, in which she describes the Miyawaki Method, a unique approach to reforestation devised by Japanese botanist Akira Miyawaki.

Comedy+Climate Change: (start time: 5:50)  In this week’s show we look ahead to Earth Day by discussing the latest science about climate change, as reported in the recently released assessment report from the Intergovernmental Panel on Climate Change. And we explore the role that performing arts, especially comedy, can play in communicating, and processing emotions around, climate change. Our guests are Max Boykoff, a professor in, and the chair of, the Environmental Studies Department at the University of Colorado Boulder, and a contributing author of the recent IPCC report; Beth Osnes, a professor of Theatre and Environmental Studies at CU Boulder, and co-director of Inside the Greenhouse, a project at the university for creative climate communication; and Henrique Sannibale, an undergraduate student at CU Boulder studying environmental studies and business.
