"Monsters Behind the Door": "Tipping Points and the Climate Challenge" (via @revkin @dotearth)

A very worthwhile DotEarth (@DotEarth) blog piece by Andrew Revkin (@revkin) on climate thresholds or "Tipping Points" beyond which climate change "suddenly becomes unstoppable," and the impact this idea is having on clear assessment of what we know and don't know about climate change.

NOAA Tsunami Warning for Hawaii: Wave arrival 1119 am HST (419 p.m. EST)

http://www.prh.noaa.gov/ptwc/?region=2&id=hawaii.2010.02.27.114829

http://www.prh.noaa.gov/ptwc/messages/hawaii/2010/hawaii.2010.02.27.114829.txt

"....A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.

"A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST. TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.

THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1119 AM HST SAT 27 FEB 2010

Dams to Go: Klamath River water deal ends long conflict between farms, fish (via @AP @sejorg)

Jeff Barnard, AP:

"A century-old fight about water from Oregon's Klamath Basin ended Thursday with signed agreements that assure farmers water and power to keep their crops green, and lay out the removal of dams that have blocked salmon from hundreds of miles of spawning grounds.

For decades, American Indian tribes, farmers, salmon fishermen and conservation groups have fought in courts and centers of power about who gets the scarce water in the basin -- the farms and ranches through irrigation or the salmon and suckers in rivers and lakes..."

Food Security: Philippines ‘Bracing for the Worst’ in Drought (via @nytimes)

http://www.nytimes.com/2010/02/20/world/asia/20phils.html

"A drought in the Philippines has destroyed millions of dollars worth of crops, reduced the country's water supply and is threatening widespread blackouts as power companies contend with low water levels in hydroelectric dams, officials said Friday.

"It is such a difficult situation because we have just survived the typhoons in October that destroyed 1.5 million metric tons of rice and countless basic infrastructure," Joel Rudinas, an under secretary at the Department of Agriculture, said Friday. "We are bracing for the worst."

"...The damage to crops is now estimated at more than $61 million, and Mr. Rudinas said the Philippines, already the world's largest importer of rice, has imported an additional 2.4 million tons because of the drought...."

The Road to Zero: That's What Bill Gates Says Our Emissions Should Be (Via @TED_TALKS @worldchanging)

http://www.ted.com/talks/bill_gates.html

TED: "At TED2010, Bill Gates unveils his vision for the world's energy future, describing the need for "miracles" to avoid planetary catastrophe and explaining why he's backing a dramatically different type of nuclear reactor. The necessary goal? Zero carbon emissions globally by 2050."

WorldChanging: Bill Gates: Most Important Climate Talk of the Year

http://www.worldchanging.com/archives/010976.html

Alex Steffen: "On Friday, the world's most successful businessperson and most powerful philanthropist did something outstandingly bold, that went almost unremarked: Bill Gates announced that his top priority is getting the world to zero climate emissions...

"..That moment was the most important thing that has happened at TED.

"Gates spoke about his commitment to using his massive philanthropic resources (the Gates Foundation is the world's largest) to make life better for people through public health and poverty alleviation ("vaccines and seeds" as he put it). Then he said something he's never said before: that is it because he's committed to improving life for the world's vulnerable people that he now believes that climate change is the most important challenge on the planet.

"Even more importantly, he acknowledged the only sensible goal, when it comes to climate emissions, is to eliminate them: we should be aiming for a civilization that produces no net emissions, and we should be aiming to live in that civilization here in the developed world by 2050...."

Op-Ed: "Overpopulation and Climate Change" (via @nytimesglobal)

http://www.nytimes.com/2010/02/18/opinion/18iht-edwesting.html

Arthur H. Westing: "...Population is a double-barreled environmental problem -- not only is population increasing; so are emissions per capita.

"...inexplicably and inexcusably, recommendations by the United States, the United Nations and independent research groups essentially never include -- and certainly never stress -- population as a contribution to global warming...."
