A large pack of bicyclists swarming down the north coast this week are riding to raise awareness of climate change—and incidentally to have a great time in the process.

While preliminary planning for a second Climate Ride on the north coast is just getting started, Carter says everything is in place for any riders who might want to join in the eastern route's third run next spring. In addition to its obvious recreational aspects, the Climate Ride is also a fund-raising event, in which each rider must raise or contribute $2,400 to participate. But co-founder Geraldine Carter says that can be done in any number of creative and satisfying ways.

Geothermal Power at The Geysers

 How about using the heat from the Earth’s core to power your home? Guess what: you already are. Solar, wind and water power are the big three natural and sustainable sources for electric power, but the North Bay also benefits from a fourth—geothermal energy.

The geological conditions that allow access to geothermal heat and steam are scattered in just a few areas around the world, almost always where the subterranean slabs of planetary rock known as tectonic plates are moving against each other. Bruce Carlsen, Calpine’s Director of Environmental Health and Safety at The Geysers, explains the underlying forces.

The same conditions often create numerous hot springs and can be a source of seismic activity—as is also the case in the North Bay. But while earthquakes can alter the flows that feed hot springs, Carlsen explains that the deeper strata that feed geothermal steam fields are not affected.

The Geysers is by far the biggest geothermal generating facility in California, but Carlsen says there are some other locations that could be developed to make a smaller contribution to the state’s energy needs.

Bruce Carlsen talks about geothermal energy in Sonoma County at an informal potluck gathering at the Glaser Center in Santa Rosa on Aug. 31, 5:30-7:30 p,m, co-hosted by the Climate Protection Campaign.

"Climate Refugees"

Flood, droughts and rising sea levels and other effects of global climate change are already displacing millions of people around the world, a situation documented in the new film, Climate Refugees.

Documentary filmmaker Michael Nash first screened Climate Refugees at the UN Climate Conference in Copenhagen last winter. The film made its domestic debut at Sundance.  And even as he hopes for US commercial distribution to kick in later this fall, Nash says he is fielding requests for showings from a growing number of governmental and church groups.

Climate Refugees is meant to be apolitical, at least in the partisan sense, says Nash (right). And even if the issue he spotlights may be new to many viewers, he observes that it has been building for years.

Nash has said his starting point for making this filnm was a desire to show “the human face of climate change.”  In doing so, he learned that one doesn’t need to go very far to find it.

Fog and Redwoods

A new analysis finds there are fewer foggy days along the Northern California coast than there were  100 years ago. That’s bad news for the venerable coast redwoods.

In addition to charting a reduction in the number of foggy days over the past century, U.C. Berkeley researcher Todd E. Dawson says their study also found fewer hours of foggy conditions on the days when the mist was present.

In their analysis, Dawson and  his colleague, James Johnstone, found there was a relationship between drought years and fog conditions, but it’s not what one might expect.
