carbon capture

Carbon trading has featured, or at least been mentioned, only rarely on this platform, now that I stop to check. That seems impossible. But the scheme with so much promise has simply not taken off. Indigenous heritage, on the other hand, has featured in dozens of stories here since we started in 2011. Thanks to Carolyn Kormann for bringing this story to my attention, helped by two captivating photos and the fact that it highlights the approach of the Yurok Tribe (a community I had not heard of before):

“I think we did a good thing by saving the trees, but I’m not happy with it,” Jene McCovey, a tribal elder, said. “It’s not viable. It allows polluters to pollute.” Photograph by Joel Redman

How Carbon Trading Became a Way of Life for California’s Yurok Tribe

When Marty Lamebear is not fighting fires, he is starting them. In the past few years, as a member of the Yurok Tribe Forestry Program’s fire department, he has been helping revive the controversial practice of prescribed burns to protect and restore the coastal redwood forests of northern California. Lamebear is also a hunter, fisherman, and dancer. In his free time, he makes tribal regalia for ceremonial dances from parts of elk, deer, minks, and porcupines, which he shoots or finds already dead, and from frozen eagles that he orders from the U.S. Fish and Wildlife Service. A prescribed burn, what Lamebear calls a culture burn, creates prairies within the forest, which attract those animals. “At first, we couldn’t really tell its effects,” he said. “But, after about six years now, we can honestly start seeing the landscape open up, animals come around.” They also serve another purpose, he said. “It’s insurance for our carbon.” Continue reading →

We’ve discussed carbon capture before, in the chemical sense with scrubbers at coal-plants and regarding the history of coal, but most of our posts have been concerned with lowering carbon emissions rather than sequestering it. Today we learned that a new technique tested in Iceland turned CO2 released from a geothermal plant into a limestone of sorts, where it appears to no longer contribute to global greenhouse gases. Damian Carrington reports for The Guardian:

Carbon dioxide has been pumped underground and turned rapidly into stone, demonstrating a radical new way to tackle climate change.

The unique project promises a cheaper and more secure way of burying CO2 from fossil fuel burning underground, where it cannot warm the planet. Such carbon capture and storage (CCS) is thought to be essential to halting global warming, but existing projects store the CO2 as a gas and concerns about costs and potential leakage have halted some plans.
