Electric Car Road Trips (starts 3:42): We go on a road trip with How on Earth’s Shelley Schlender to see how all-electric vehicles are exceeding “range anxiety” by driving coast to coast, all on electricity. Along the way we talk with Boulder Nissan’s Nigel Zeid about regional plans to help more drivers “plug in” and with Hunter Lovins, head of Natural Capitalism Solutions.
Leaky Natural Gas Wells (start time 6:22). We speak with Greg Frost, a scientist from the University of Colorado at Boulder and the National Oceanic and Atmospheric Administration (NOAA), about a new study, which is being published by the Journal of Geophysical Research. The study indicates that natural gas drilling creates higher amounts of methane leakage into the atmosphere than previous estimates had indicated. Methane is a potent greenhouse gas, and unless this problem of leakage is solved, there is concern that drilling for natural gas might cause higher levels of greenhouse gases in the atmosphere than burning coal. We also offer an extended version of this interview.
Recent Contributions of Glaciers and Ice Caps to Sea Level Rise (start time 14:25). Scientists at CU’s Institute of Arctic and Alpine Research now have used eight years worth of satellite data to a clearer picture of how climate change is impacting the cryosphere, or ice-covered parts of the planet. (See animations here.) Knowing how much ice has been lost during this time can help scientists understand how melting ice might contribute to sea level rise, both now and in the future. But there have been conflicting stories in the press about how the results should be interpreted. We talk with Tad Pfeffer, one of the study’s coauthors, to discuss what’s really happening to the Earth’s ice.
