Global warming to heighten risk of Southwestern megadroughts
Posted by Washington Post: Juliet Eilperin on September 3rd, 2014
Washington Post: Exceptional drought, the most severe category, afflicts over 58 percent of California. The current drought may be a mere sneak preview of longer lasting and more devastating drought in the coming century, according to a study published in the Journal of Climate.
The study -- by Cornell University, University of Arizona and U.S. Geological Survey researchers -- examines the likelihood of so-called "megadroughts" and how they may change as the climate warms. Megadroughts are distinguished by their...

Comments Off on Global warming to heighten risk of Southwestern megadroughtsGeorge Bush: Climate Change Is a Threat
Posted by New Republic: Rebecca Leber on September 3rd, 2014
New Republic: George P. Bush, heir apparent in the family political dynasty, just acknowledged that climate change is real, linked it to sea level rise and extreme weather, and suggested we find ways of adapting to it. That’s pretty remarkable, given that Republicans almost never say such things--and that Bush, who is running for the office of state Land Commissioner, is already touted by some as the party’s future.
Here’s the key excerpt from the Texas Tribune’s Neena Satija interview with Bush published over...
Extinctions During Human Era 1000 Times Worse
Posted by Nature World: Jenna Iacurci on September 3rd, 2014
Nature World: Amid a world with advancing technologies, increasing land development and human-driven climate change, the world's species are becoming extinct 1,000 times faster than they used to, according to new research.
Extinctions are about 1,000 times more frequent now than in the 60 million years before people came along - that's 10 times worse than scientists previously thought.
"This reinforces the urgency to conserve what is left and to try to reduce our impacts," lead author Jurriaan de Vos, a...
Wildfire near California-Oregon border ‘extreme,’ firefighters say
Posted by Washington Post: Juliet Eilperin on September 3rd, 2014
Reuters: Firefighters battling a fast-moving Northern California blaze said Wednesday they expect a second day of extreme conditions, as heat and high winds spur a lightning-sparked wildfire near the Oregon border.
The so-called Happy Camp Fire has been burning in the Klamath National Forest since Aug. 11, consuming 72,000 acres and costing an estimated $41 million so far in firefighting costs.
"Yesterday, we had an increase in extreme fire behavior ... and we do expect the same extreme fire today,...

Blue and Green: An advert from US fracking company Breitling Energy, which claimed that the UK suffered from a “near-catastrophic” gas shortage last winter and talked up the benefits of shale gas, has been banned.
The Advertising Stands Authority (ASA) received a complaint about the advert, which appeared in the Telegraph earlier this year, stating that the claims made were misleading, which has been upheld.
The advert was addressed to “citizens of the United Kingdom” and suggested that shale gas estimates...

Blue and Green: The extinction rate of species around the world is now 1,000 times higher than it was before humans arrived on the scene, a new study has found.
The shocking report, published in the journal Conservation Biology, estimates the pre-human extinction to be 10 times lower than scientists previously thought, making mankind’s devastating impact all the more pronounced.
"We`ve known for 20 years that current rates of species extinctions are exceptionally high," said co-author Stuart Pimm, of Duke...
Mountain species & ecosystems face threats from climate change
Posted by Science World Report: None Given on September 3rd, 2014
Science World Report: As our climate changes, mountain species may be facing an uphill climb. Scientists have taken a closer look at mountain ecosystems and have examined the issues threatening wildlife in these systems in order to create better targeted conservation efforts.
Mountains cover about 27 percent of the earth's surface. Despite some degree of protection due to the fact that they aren't easily accessed, though, mountain regions are still fragile ecosystems that are threatened by human-related impacts such...

Posted by Richmond Times-Dispatch: Rex Springston on September 3rd, 2014
Richmond Times-Dispatch: The state should name a leader in preparing coastal Virginia for flooding linked to rising sea levels, a new report says. The recommendation is one of about two dozen in the draft report of a subpanel of the Secure Commonwealth Panel, which is advising Gov. Terry McAuliffe on emergency management issues. Rising seas and coastal flooding in Virginia pose threats to waterfront developments; historic areas like Jamestown; low-lying communities; and military bases like Naval Station Norfolk, the world’s...

Posted by Washington Post: Juliet Eilperin on September 3rd, 2014
USA Today: California is in the third year of one of the state's worst droughts in the past century, one that's led to fierce wildfires, water shortages and restrictions, and potentially staggering agricultural losses. The dryness in California is only part of a longer-term, 15-year drought across most of the Western USA, one that bioclimatologist Park Williams said is notable because "more area in the West has persistently been in drought during the past 15 years than in any other 15-year period since the...
Global warming: How rising alpine vegetation could hit California water supply
Posted by Washington Post: Juliet Eilperin on September 3rd, 2014
Christian Science Monitor: A warming-climate-induced march of alpine vegetation up a large river basin on the western slope of the Sierra Nevada could slash by one-fourth the annual flow of water the basin delivers to California’s thirsty Central Valley by the last two decades of this century, a new study says.
The results of the Kings River Basin study imply that the same type of risk holds for another 10 major river basins along the western Sierra, although to varying degrees, say the researchers involved in the study....
