Big Game and Climate Change (start time 5:00) Last week, the National Resource Council released some serious warnings about climate change, saying its impacts could be abrupt and surprising. But as How on Earth contributor Brian Calvert reports, the National Wildlife Federation says big game is already getting hit. Species from mule deer to antelope to bear are all dealing with climate change in their own ways. Only elk are faring better, at least for now. All of that could mean serious changes for Colorado’s hunters and wildlife watchers, says, Dr. Doug Inkley, the senior wildlife biologist for the organization and the lead author of a recent report, “Nowhere to Hide: Big Game Wildlife in a Warming World.”
Hour of Code (start time 12:30) Coding is not just a magic trick where ones and zeros make Angry Birds. But it can be surprisingly simple to learn. You can do it in an hour. But you might want to use a game built by a team here at CU-Boulder. The tutorial is being offered as part of Computer Science Week. In the studio with How On Earth’s Joel Parker to explain the university’s so-called “Hour of Code” is Alex Repenning, a computer science professor at CU.

On Tuesday, Nov. 26, How On Earth brings you two features:
Feature #1: (start time 5:53) STEM, as you may well know, stands for Science, Technology, Engineering and Mathematics. Many math and science topics are introduced throughout most years of primary education, but technology and engineering — not so much. We live in a world surrounded by things imagined and designed and built by engineers, from roads and buildings to computers and appliances and even food, drugs and clothing. So it’s important to understand engineering if we want to understand these life necessities. An educator tackling this issue is Dr. Christine Cunningham, vice president of research and educator resource development for a project called “Engineering is Elementary.” It was developed by the Museum of Science in Boston. Cunningham is featured in an article, written by former How On Earth contributor Breanna Draxler, called “E is for Engineering” in the December issue of Discover magazine. Cunningham talks with host Joel Parker about how teaching engineering to very young students can be done.
Feature #2: (start time 14:45) Arguably the healthiest marine ecosystem on Earth is the Ross Sea in Antarctica. It’s so pristine largely because it is protected by a 500-mile-wide shield of floating sea ice, and, well, it’s not exactly easy to get to. But in recent years the Ross Sea has come under threat, largely from New Zealand industrial fishing ships that are hunting as far south as they can for the Antarctic toothfish, which was rebranded as Chilean sea bass for U.S. and other consumers. John Weller is a nature photographer and conservationist living in Boulder. He has documented the beauty and fragility of the Ross Sea in his new book, The Last Ocean. Weller also co-founded a nonprofit, called The Last Ocean Project, that is dedicated to protecting the Ross Sea and other fragile marine ecosystems. Weller talks about the science and art of these environments with host Susan Moran. (You also can hear a previous interview with Weller on KGNU’s Morning Magazine.)

We offer two features on the Tuesday, Oct. 22, show:
Feature 1 – Antarctica Research (start time 4:15): Diane McKnight, a professor of civil, environmental and architectural engineering at the University of Colorado Boulder, talks with How On Earth contributor Brian Calvert about scientific discoveries from Antarctica. During the temporary government shutdown the United States Antarctic Program, which facilitates government-funded scientific research in Antarctica, was unplugged. Several expeditions were cancelled. Her research on the McMurdo Dry Valleys on the continent will resume, but a future government shutdown would threaten scientific research on penguins, extreme microbes, climate change-induced sea ice melt and so many other subjects.
Feature 2 – The Cancer Chronicles (start time 12:22): In his new book, The Cancer Chronicles: Unlocking Medicine’s Deepest Mystery, science writer George Johnson takes readers on his very personal quest to understand cancer on a cellular level: how it begins with one “renegade cell” that divides, mutates, and becomes a tumor. In the process Johnson also digs deep into history – per-history, in fact — to learn that not only our ancient human ancestors had cancer, but even some dinosaurs suffered from them. And the author dissects many scientific studies that debunk myths about the role environmental toxins play in cancer. And he challenges false beliefs that cancer in modern times is on the rise. “Yet running beneath the surface is a core rate of cancer, the legacy of being multicellular creatures in an imperfect world,” he writes. Johnson speaks via phone to host Susan Moran about the mysteries and discoveries of cancer.
And as we mentioned in today’s headlines, if you want to see the large fragment of the Chelyabinsk meteor being recovered from Lake Chebarkul, you can see the video here.

For the Sept. 3rd How On Earth show we offer two features:
Wildfires Threaten Water Supplies: (start time 5:45) The wildfire burning in and around Yosemite National Park is now the fourth-largest in California’s history. Covering nearly 350 square miles, the Rim Fire is threatening the Hetch Hetchy Reservoir, which supplies residents in the San Francisco Bay Area with most of their water and power. It’s a lot like the 2012 High Park Fire—which sent ash and debris into the water supply of Fort Collins. These fires offer lessons on the risks wildfires pose to reservoirs. Dr. Bruce McGurk, a former water manager for Hetch Hetchy and a water consultant, speaks with How On Earth contributor Brian Calvert about the risks and future prospects.
Comet ISON Cometh: (start time 12:50) Comets have fascinated humans for millenia. Aristotle argued comets were hot, dry exhalations gathered in the atmosphere and occasionally burst into flame. Some people thought that comets replenished Earth’s air. Still others believed they were a source of disease. Scientists today study comets because some are thought to be relatively pristine leftover debris from the formation of the solar system. And studying what comets are made of can provide us a glimpse back to the beginning of the solar system 4 billion years ago. Comet ISON, as scientists call it, is one that scientists predict will be relatively easy to view later this year. Dr. Carey Lisse, a senior research scientist at the Johns Hopkins Institute Applied Physics Laboratory in Maryland, speaks with co-host Joel Parker about comet ISON and its fascinating tails. For more information on ISON, go to NASA’s ISON toolkit, and this cool interactive model.
