Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

RIM FIRE Balloons to 288mi²

Posted by feww on August 28, 2013

Giant Calif. blaze rapidly spreads to 184,481 acres

The ferocious fire has extensively damaged Berkeley Tuolumne Camp and the infrastructure. Rapid fire growth and extreme fire behavior are hampering suppression efforts, said USFS.

The blaze had consumed about 42,000 acres of Yosemite National Park by early Tuesday.

RIM FIRE has also damaged two of the three hydroelectric generating stations at the O’Shaughnessy Dam, which supply electricity for all of San Francisco’s public facilities. The dam impounds the Tuolumne River at the lower end of Hetch Hetchy Valley in Yosemite National Park, while the reservoir provides 85% of the water for the San Francisco Bay Area.

The monster blaze is now the 7th largest in California’s history (and climbing the chart), less than 90,000 acres behind Cedar Fire (273,246 acres), the largest fire ever recorded in California, which left 14 people dead and more than 2,820 structures destroyed in San Diego area, October 2003.

The raging fire was creeping closer to thousands of homes located west of Yosemite National Park, as of posting.

RIM FIRE Spreads to about 180,000 Acres

Posted by feww on August 27, 2013

Ferocious fire becomes 7th largest in California history

Rim Fire wildfire consumed an additional 20,000 acres (~12.5%) overnight, charring a total of at least 179,481 acres (280mi², or 726km²) by 07:30 PDT (UTC -7 hours) on Tuesday, reported Cal Fire.

The massive fire spread further east and north overnight, pushing deeper into Yosemite National Park. The eastern flank of the blaze has now burned to within a few hundred yards of Hetch Hetchy reservoir, which supplies most of San Francisco’s water.

The monster blaze is now the 7th largest in California’s history (and climbing the chart), less than 94,000 acres behind Cedar Fire (273,246 acres), the largest fire ever recorded in California, which left 14 people dead and more than 2,820 structures destroyed in San Diego area, October 2003.

Seventeen of the the top 20 wildfires in California have occurred since 1985.

RIM FIRE has already destroyed 111 (31 residences, 80 outbuildings), according to Cal Fire.

However, an earlier news bulletin by Reuters said the blaze had destroyed homes and “1,000 outbuildings…

RIM FIRE Raining Ash on Key SF Reservoir

Posted by feww on August 27, 2013

Explosive blaze devours at least 160,980 acres (251.53mi²)

Rim Fire is burning less than a mile from Yosemite’s Hetch Hetchy reservoir on the Tuolumne River, raining ash on San Francisco’s main water source.

The massive fire had blackened at least 22,000 acres within YNP as of Monday morning, forcing the closure of Highway 120, the main road leading into the park from the San Francisco Bay area, and prompting evacuation of the remainder of 74 campsites in the park’s White Wolf area, officials said.

Although the fallout of ash and soot has not yet significantly deteriorated the Hetch Hetchy’s water quality, officials fear winter rains could cause runoff of debris and topsoil, which is stripped of vegetation by the blaze, severely affecting the reservoir.

“When you burn down everything, you’ve got a moonscape out there when floods can contaminate the water,” said California Gov. Brown on Monday during a visit to the fire zone. Brown declared a state of emergency for City and County of San Francisco on Friday due to threats to the city’s electricity and water supplies.
