Ocean Power Can Be a Global Warming Cure |

Why
is the government still looking to spend billions on new coal-fired
power plants when clean energy sources are at our fingertips?
How
shall we ever slake our ever-growing demand for electricity? Even as
concerns about global warming escalate, are we doomed to create more of
the same old polluting, coal- and oil-dependent power plants? Or can
common sense - and some radically new technologies - serve us better?
There's
much talk of wind and solar power. But how about the oceans and their
massive tidal and current patterns? Driven by the gravitational force
of the sun and the moon, tides and currents represent a source that's
as infinite and everlasting as any force on earth.
A
major pilot demonstration seems ready to launch in San Francisco Bay,
where an immense tidal flow enters and exits every day at a narrow
point of the Golden Gate. A gigantic energy-collection device vaguely
reminiscent of a Ferris wheel, with a number of fins (or "wings") to
capture the power of the rapidly passing tides, will be lowered from a
barge anchored in the narrows. Using maglev technology, it will produce
electrical energy that can then be transmitted to shore by cable.

Can Clean Insurance Fend Off Global Warming? |

Al Gore's new film, "An Inconvenient Truth," has helped to focus
public attention on the danger of global warming. It is good news that more
people are now aware of the problem, but the real question is what are we going
to do about it?
Well, if Gore produces a sequel, the hero could be a car insurance salesperson.
To stop global warming, we will have to radically reduce our consumption of
fossil fuels. This will not be easy, but there are some easy places to start,
and car insurance tops the list.
The basic story is simple. People currently buy car insurance on an "all
you can eat" basis. No matter how much you drive, you pay pretty much the
same amount for your auto insurance. (Some insurers offer modest low mileage
discounts, but these discounts are generally small relative to the cost of the
policy.) Therefore, drivers have little incentive to take into account the cost
of their insurance when they decide whether to drive their car.

World Must Race to Develop Green Energy, Urges Rees |

Friday 04 August 2006
Research drive 'must rival the Apollo moon project.' Royal Society president warns of climate disaster.
An
urgent project on the scale of the Apollo moon landings is needed to
boost research into green energy sources and save the planet from
environmental disaster, according to Britain's top scientist.
Writing
in the US journal Science today, Sir Martin Rees, president of
Britain's most prestigious scientific institute, the Royal Society,
expresses dismay at G8 leaders' "worrisome lack of determination" to
accelerate development of new energy sources, given the expected 50%
rise in the world's energy needs - and carbon dioxide emissions - in
the next 25 years.
He
warns that without an international, focused programme to develop
alternatives to fossil fuels it will be impossible to keep greenhouse
gas emissions low enough to prevent catastrophic climate change.

Clinton, Mayors Form Alliance on Climate |

Tuesday 01 August 2006
Los
Angeles - Former President Clinton and mayors of some of the world's
largest cities announced an initiative Tuesday to combat climate change
and increase energy efficiency in everything from street lights to
building materials.
The
partnership joins Clinton and the resources of his presidential
foundation with the Large Cities Climate Leadership Group - an alliance
of Rome, London, Mexico City, Los Angeles and other cities that have
pledged to cut greenhouse gas emissions.
The
aim is to pool technology and resources to slash the pollutants that
contribute to global warming while promoting clean-burning fuels and
energy conservation.

Toxic algae that poison the brain have caused strandings and mass die-offs of marine mammals - barometers of the sea's health.
After
the last patient of the day walked out the front of Raytel Medical
Imaging clinic, veterinarian Frances Gulland slipped an oversized
animal crate through the back door.
Inside was a California sea lion. The animal was emaciated, disoriented and suffering from seizures.
A
female with silky, caramel-colored fur, wide-set eyes and long
whiskers, she was named Neuschwander, after the lifeguard who had found
her six weeks earlier, comatose and trembling under a pier at Avila
Beach near San Luis Obispo.
Taken
to the Marine Mammal Center near Sausalito, Neuschwander showed signs
of recovery at first. Her eyes began to clear and focus. She frolicked
in the small pool in her chain-link enclosure and wolfed down mackerel
at feedings. Then she relapsed.

Britain, California to Join Forces on Global Warming |

Go to Original
The Associated Press
Monday 31 July 2006
Washington
- Britain and California are preparing to sidestep the Bush
administration and fight global warming together by creating a joint
market for greenhouse gases.
British
Prime Minister Tony Blair and California Gov. Arnold Schwarzenegger
plan to lay the groundwork for a new trans-Atlantic market in carbon
dioxide emissions, The Associated Press has learned. Such a move could
help California cut carbon dioxide and other heat-trapping gases
scientists blame for warming the planet. President Bush has rejected
the idea of ordering such cuts.
Blair
and Schwarzenegger were expected to announce their collaboration Monday
afternoon in Los Angeles, according to documents provided by British
government officials on condition of anonymity because the announcement
was forthcoming.
The
aim is to fix a price on carbon pollution, an unwanted byproduct of
burning fossil fuels like coal, oil and gasoline. The idea is to set
overall caps for carbon and reward businesses that find a profitable
way to minimize their carbon emissions, thereby encouraging new,
greener technologies.

More Than 60 Percent of US in Drought |

The Associated Press
Saturday 29 July 2006
Steele, N.D. - More than 60 percent of the United States now has abnormally
dry or drought conditions, stretching from Georgia to Arizona and across the
north through the Dakotas, Minnesota, Montana and Wisconsin, said Mark Svoboda,
a climatologist for the National Drought Mitigation Center at the University
of Nebraska at Lincoln.
An area stretching from south central North Dakota to central South Dakota
is the most drought-stricken region in the nation, Svoboda said.
"It's the epicenter," he said. "It's just like a wasteland in north central
South Dakota."

Better Get Used to Killer Heat Waves |

The Associated Press
Friday 28 July 2006
In Fresno, the morgue is full of victims from a California heat wave. A combination
of heat and power outages killed a dozen people in Missouri. And in parts of
Europe, temperatures are hotter than in 2003 when a heat wave killed 35,000
people.
Get used to it.
For the next week, much of the nation should expect more "extreme heat,"
the National Weather Service predicts.
In the month of August, most of the United States will see "above normal
temperatures," forecasters say.
For the long-term future, the world will see more and worse killer heat waves
because of global warming, scientists say.
