Fireproofing Mountain Homes (starts at 3:20) We discuss a new study from the Rocky Mountain Research Station in Missoula, Montana. It warns that thinning forests may help prevent property damage from the “typical” wildfires, fire suppression can’t stand up against the 3% of fires that burn super-hot and spread super fast. What’s more, the Missoula study warns that superhot wildfires are just the ones that burn the most homes. The researchers conclude that the main responsibility for preventing home destruction from wildfires, lies with homeowners rather than public land managers. They say that homeowners should do more to design homes that stand up to a super wildfire. To find out ways to to that, we talk with Disaster Safety Senior Scientist Steve Quarles, who is with an insurance industry funded fire prevention think tank. Quarles says that small changes in home building can reduce the chance that tiny, glowing embers blowing in the wind, will get in under the eaves and turn into a raging fire that burns down a house.
Winter Solstice (starts at 13:44) As a chart of sunrise and sunset makes clear, although the shortest day of the year is at the winter solstice, the latest sunrise occurs *after* the solstice and the earliest sunset occurs *before* the solstice… The sunset is going to get later faster and faster now, while the sunset time is going to also get later until after the solstice, then start creeping earlier. What’s going on here? How on Earth’s Jim Pullen explains.

Feature 1 – Tesla (start time 5:30) Nicola Tesla is one of the iconic figures of the early electrical age. He invented AC motor technology still used today in your DVD player and also polyphase AC power. He was a brilliant demonstrator, whose images of flowers of lightning growing from his inventions and portraits of his friend Mark Twain, illuminated by Tesla’s fluorescent bulbs, are still familiar today. He worked with and fought with the mighty JP Morgan and wireless radio great Marconi. He is a figure of mystery, who many believe presaged death rays and infinite and free energy for everyone on earth. Biographer

Feature 1 – Flood Winners & Losers : Last month’s deluge cut canyons, real and felt, through many of our lives, but nature helps us remember that floods can build too. In this feature, How on Earth’s Jim Pullen speaks with Boulder’s wetland and riparian ecologist Marianne Giolitto about flood “winners and losers”. Marianne watches over 45,000 acres of the city’s open space and mountain parks wetlands and riparian habitats. Jim and the Boulder Open Space and Mountain Parks are working together on a
