Open Call to Congressional Republicans: Stand Up to the Democrats in Congress, or face a Tea Party Rebellion in your own Ranks
by JB Williams
It’s official folks, with the Democrats steamrolling over the GOP filibuster intended to stop another TRILLION in wasteful spending yesterday, Republicans in congress have been handed their hat once again.
Do you republicans not know that you are completely irrelevant? Or do you just not have the spine to take a real stand? Democrats are making asses out of all of you!
This is NOT a game! The future of freedom and liberty hang in the balance and most Americans know it! How did you miss it?
Republican congressional votes have NO meaning today. So what, if you are “on-record” voting against the global socialist leap off the leftist cliff? Unless you find a way to derail that speeding locomotive, you will soon burn in a Marxist hell with the rest of us.
When American freedom and liberty are gone and every American is forced into a financial corner where socialism looks better than starvation, it won’t matter who voted against it!
With the loss of the filibuster, Congressional Republicans have only ONE play left to stop the coming train wreck, when Obamunism runs head-on into millions of increasingly angry American patriots in the streets. Only Congressional Republicans can stop that clash!
Congressional Republicans MUST WALK OUT immediately!
You must pack your bags, close your offices, refuse to enter the congressional chambers for one more pretend vote in which the Democrats will hand you your hat once again.
If Republicans want to harness the power of the Tea Party – 912 – and Town Hall patriots across this land, you can do it in three simple steps…
· Shut down congress by walking out and refusing to return. Can Democrats even call something to a floor vote without a single republican in the chamber? Would they even dare try it?
· Return home and spend time listening to angry patriots in as many town hall meetings as you can schedule. You will earn your pay at a town hall, whereas attending another congressional vote is worse than a waste of time. It’s counter-productive. Go home and listen, don’t talk!
· Grow the backbone to walk away from all of your past mistakes, and line up behind the ONLY people who can put you back in power, the American patriots who stand for a constitutional government and against the current steamroller to socialism.
You have only one other option… to keep doing what you’re doing, which amounts to being a big part of the problem, instead of a part of the solution.
WALK OUT TODAY!
GO HOME! - And set up as many town hall meetings in your home districts as you can fit into your schedule. Earn your paycheck by meeting with the people, so that you can once again begin to represent the will of the people. Don’t talk – LISTEN!
Tell Democrats that if they are determined to lead this country into the toilet, they will have to do it all alone without a single republican in the chamber when they do it, one lousy piece of anti-American legislation after another.
Republicans have a very clear choice to make and you had better make it fast! The nation doesn’t need two parties full of leftist losers. Republicans willing to stay in session should be seen not as “RINOs,” but as Democrats… and they will be.
You can take a stand with the 70% of Americans who DO NOT want any form of Cap & Trade, Global Socialized Medicine, a One World Government, the Copenhagen Climate Scam, Amnesty for Illegal’s, or trillion dollar payoffs to leftist organizations and labor unions which only enrich the leftist juggernaut now running roughshod over the nation. Only 25% “strongly approve” of Obamunism as of today… It’s time for you to strike!
Severe situations demand severe action!
We are out of time for any other option. The Tea Party – 912 and Town Hall people will not – I repeat – WILL NOT line up behind Republicans too spineless to put a stop to the hourly destruction of this nation.
Republicans have ONLY one way to regain any form of power, and that is to toss out the politically correct nonsense of the past and line up behind the millions of patriots begging for action across this country!
Republicans either line-up behind the American right in a hurry, or their party is finished, as is this nation.
WALK OUT IMMEDIATELY! – And DO NOT RETURN until you have control of congress next November!
I call upon EVERY Washington DC Republican to walk out NOW!
This is NOT an issue item! This is NOT a circus stunt sideshow. WALK OUT and STAY OUT! Refuse to participate in the rape of this great nation!
If you continue to sit in that chamber and watch the gang rape of this nation, you are NO BETTER than the rapists! GET OUT of that chamber NOW! Let the American people see the rapists clearly!
God help us all if YOU lack the courage to do what must be done to save this nation!

The Political Aftermath of Bailouts
The Obama administration is again pressing banks to increase lending, explicitly sugesting that banks "owe" the country because of the bailouts. Chief administration economist Larry Summers, for example, said Sunday:
“We were there for them and the banks need to do everything they can to be sure they’re there for customers across this country,” Summers said in an interview on ABC’s “This Week” program.
President Obama pressured the heads of the nation’s biggest banks on Monday to take “extraordinary” steps to revive lending for small businesses and homeowners, drawing a firm commitment from one large bank to make more loans and vaguer assurances from others.
This kind of jaw-boning, with its implicit threats, is one crucial negative of the bailouts, and it will contaminate policy for a long time.
It is true that the banks benefited from taxpayer largesse. But they presumably have a reason now for their limited lending: they do not see profitable lending opportunities. If the administration bludgeons them into increasing credit, the banks will end up making bad loans that ultimately fail, creating yet another excuse for bailouts.
We made one huge mistake: the bailout. We should not compound it with another mistake: interfering with private lending decisions. Instead, we must lest the recovery take its course. And we should recognize that one reason for the slow recovery is private sector concern about incessant government meddling.
Adam Andrzejewski for Illinois Governor: Deserving of Conservative and Libertarian support
Adam Brickley, Founder of Draft Sarah Palin for VP 2008, has just interviewed Republican candidate for Illinois Governor Andre Andrzejewski. He is the insurgent Tea Party Patriot in 2nd place in the GOP primary, fighting against the GOP establishment whose backing tax raiser, and former Governor, moderate Republican Jim Ryan. Andrzejewski is an entrepreneur, and government reformer. He says in the interview that his main political mentor is libertarian-leaning Gov. Mitch Daniels, and that he'd model his administration after the tight-fisted Indianan. He also gave these two following answer to a lightening round of brief questions:
AB: Alright, ten seconds: Sarah Palin.
AA: I like Sarah Palin. She put the check register – the checkbook of Alaska online. She took the old boys’ codified permanent, professional political class of Alaska, and she beat ‘em, and she should run for President.
AB: Glenn Beck.
AA: Oh, I like Glenn Beck. [What] I think of Glenn Beck is that social conservatives and libertarians – that’s the marriage that Ronald Reagan created to be the winning majority back when times were good and we brought down the Soviet Union without firing a shot. Social conservatives, like myself, with libertarian leanings, we need Glenn Beck.

NASA’s WISE Eye on the Universe Begins All-Sky Survey Mission
WISE has launched from Vandenberg Air Force Base, Calif. Image credit: United Launch Alliance
NASA's Wide-field Infrared Survey Explorer, or WISE, lifted off over the Pacific Ocean this morning on its way to map the entire sky in infrared light.
A Delta II rocket carrying the spacecraft launched at 9:09 a.m. EST from Vandenberg Air Force Base in California. The rocket deposited WISE into a polar orbit 326 miles above Earth.
"WISE thundered overhead, lighting up the pre-dawn skies," said William Irace, the mission's project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "All systems are looking good, and we are on our way to seeing the entire infrared sky better than ever before."
Engineers acquired a signal from the spacecraft via NASA's Tracking and Data Relay Satellite System just 10 seconds after the spacecraft separated from the rocket. Approximately three minutes later, WISE re-oriented itself with its solar panels facing the sun to generate its own power. The next major event occurred about 17 minutes later. Valves on the cryostat, a chamber of super-cold hydrogen ice that cools the WISE instrument, opened. Because the instrument sees the infrared, or heat, signatures of objects, it must be kept at chilly temperatures -- its coldest detectors are less than minus 447 degrees Fahrenheit.
"WISE needs to be colder than the objects it's observing," said Ned Wright of UCLA, the mission's principal investigator. "Now we're ready to see the infrared glow from hundreds of thousands of asteroids, and hundreds of millions of stars and galaxies."
With the spacecraft stable, cold and communicating with mission controllers at JPL, a month-long checkout and calibration is underway.
WISE will see the infrared colors of the whole sky with sensitivity and resolution far better than the last infrared sky survey, performed 26 years ago. The space telescope will spend nine months scanning the sky once, then one-half the sky a second time. The primary mission will end when WISE's frozen hydrogen runs out, about 10 months after launch.
Just about everything in the universe glows in infrared, which means the mission will catalog a variety of astronomical targets. Near-Earth asteroids, stars, planet-forming disks and distant galaxies all will be easy for the mission to see. Hundreds of millions of objects will populate the WISE atlas, providing astronomers and other space missions, such as NASA's planned James Webb Space Telescope, with a long-lasting infrared roadmap.
JPL manages the Wide-field Infrared Survey Explorer for NASA's Science Mission Directorate in Washington. The mission was competitively selected under the Explorers Program, managed by NASA's Goddard Space Flight Center in Greenbelt, Md. The science instrument was built by the Space Dynamics Laboratory in Logan, Utah, and the spacecraft was built by Ball Aerospace & Technologies Corp. in Boulder, Colo. Science operations and data processing take place at the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena. NASA's Launch Services Program at NASA's Kennedy Space Center, Fla., managed the payload integration and the launch service.

New Study Turns Up the Heat on Soot’s Role in Himalayan Warming
Soot from fire in an unventilated fireplace wafts into a home and settles on the surfaces of floors and furniture. But with a quick fix to the chimney flue and some dusting, it bears no impact on a home’s long-term environment.A new modeling study from NASA confirms that when tiny air pollution particles we commonly call soot – also known as black carbon – travel along wind currents from densely populated south Asian cities and accumulate over a climate hotspot called the Tibetan Plateau, the result may be anything but inconsequential.
In fact, the new research, by NASA’s William Lau and collaborators, reinforces with detailed numerical analysis what earlier studies suggest: that soot and dust contribute as much (or more) to atmospheric warming in the Himalayas as greenhouse gases. This warming fuels the melting of glaciers and could threaten fresh water resources in a region that is home to more than a billion people.
Lau explored the causes of rapid melting, which occurs primarily in the western Tibetan Plateau, beginning each year in April and extending through early fall. The brisk melting coincides with the time when concentrations of aerosols like soot and dust transported from places like India and Nepal are most dense in the atmosphere.
"Over areas of the Himalayas, the rate of warming is more than five times faster than warming globally," said William Lau, head of atmospheric sciences at NASA’s Goddard Space Flight Center in Greenbelt, Md. "Based on the differences it’s not difficult to conclude that greenhouse gases are not the sole agents of change in this region. There’s a localized phenomenon at play."
Nicknamed the “Third Pole”, the region in fact holds the third largest amount of stored water on the planet beyond the North and South Poles. But since the early 1960s, the acreage covered by Himalayan glaciers has declined by over 20 percent. Some Himalayan glaciers are melting so rapidly, some scientists postulate, that they may vanish by mid-century if trends persist. Climatologists have generally blamed the build-up of greenhouse gases for the retreat, but Lau’s work suggests that may not be the complete story.
He has produced new evidence suggesting that an “elevated heat pump” process is fueling the loss of ice, driven by airborne dust and soot particles absorbing the sun’s heat and warming the local atmosphere and land surface. A related modeling study by Lau and colleagues has been submitted to Environmental Research Letters for publication.
A unique landscape plays supporting actor in the melting drama. The Himalayas, which dominate the plateau region, are the source of meltwater for many of Asia’s most important rivers—the Ganges and Indus in India, the Brahmaputra in Bangladesh, the Salween through China, Thailand and Burma, the Mekong across Laos, Cambodia and Vietnam, and the Yellow and Yangtze rivers in China. When fossil fuels are burned without enough oxygen to complete combustion, one of the byproducts is black carbon, an aerosol that absorbs solar radiation (Most classes of aerosols typically reflect incoming sunlight, causing a cooling effect). Rising populations in Asia, industrial and agricultural burning, and vehicle exhaust have thickened concentrations of black carbon in the air.
Sooty black carbon travels east along wind currents latched to dust – its agent of transport – and become trapped in the air against Himalayan foothills. The particles’ dark color absorbs solar radiation, creating a layer of warm air from the surface that rises to higher altitudes above the mountain ranges to become a major catalyst of glacier and snow melt.
Building on work by Veerabhardran Ramanathan of the Scripps Institution of Oceanography, San Diego, Calif., Lau and colleagues conducted modeling experiments that simulated the movement of air masses in the region from 2000 to 2007. They also made detailed numerical analyses of how soot particles and other aerosols absorb heat from the sun.
"Field campaigns with ground observations are already underway with more planned to test Lau’s modeling results," said Hal Maring who manages the Radiation Sciences program at NASA Headquarters in Washington. "But even at this stage we should be compelled to take notice."
“Airborne particles have a much shorter atmospheric lifespan than greenhouse gases,” continued Maring. “So reducing particle emissions can have much more rapid impact on warming.”
"The science suggests that we’ve got to better monitor the flue on our 'rooftop to the world," said Lau. "We need to add another topic to the climate dialogue."

A Unique Geography — and Soot and Dust — Conspire Against Himalayan Glaciers
"So many disparate elements, both natural and man-made, converge in the Himalayas," said William Lau, a climatologist from NASA’s Goddard Space Flight Center in Greenbelt, Md. "There’s no other place in the world that could produce such a powerful atmospheric heat pump," referring to a new hypothesis he’s put forward to explain the rapid retreat of Himalayan glaciers in recent decades.The Himalayas, home to the tallest mountains on Earth, include more than 110 peaks and stretch 2,500 kilometers (1,550 miles). Bounded to the north by the Tibetan Plateau, to the west by deserts, and to the south by a bowl-like basin teeming with people, the mountains hold 10,000 glaciers.
These massive rivers of ice spill off mountain sides and grind down through creviced valleys. In the spring, when the monsoon carries moist air from the Indian Ocean, the glaciers begin to thaw, replenishing lakes, streams, and some of Asia's mightiest rivers, on which more than a billion people depend.
South of the Himalayas -- which forms the east-west edge of the table-like Tibetan Plateau -- the mountains give way to the Indo-Gangetic plain, one of the most fertile and densely populated areas on Earth. The plain has become a megalopolis of cities including Delhi, Dhaka, Kanpur, and Karachi, as well as a hotspot for air pollution, with a steady supply of industrial soot mixing with ash and other particles in the air.
To the west, in the northwestern part of the Indian subcontinent, the Thar Desert stretches across 200,000 square kilometers (77,000 square miles) of arid, dusty land. During the spring, westerly winds pluck dust and sand from the Thar and blow it toward the Indo-Gangetic plain.
The dust joins a mash of industrial pollutants to create a massive brown cloud visible from space. Underneath the brown cloud, some solar radiation is blocked from reaching the surface, causing the under-lying land surface to cool.
"Surprisingly, these brown aerosol clouds seem to have potent climate consequences that affect the entire region," Lau said.
The thick soot and dust layer absorbs solar radiation, and heats up the air around the Himalayan foothills. The warm, rising air enhances the seasonal northward flow of humid monsoon winds, forcing moisture and hot air up the slopes of the Himalayas.
As the aerosol particles rise on the warm, convecting air, they produce more rain over northern India and the Himalayan foothill, which further warms the atmosphere and fuels a "heat pump" that draws yet more warm air to the region.
"The phenomenon changes the timing and intensity of the monsoon, effectively transferring heat from the low-lying lands over the subcontinent to the atmosphere over the Tibetan Plateau, which in turn warms the high-altitude land surface and hastens glacial retreat," Lau said. His modeling shows that aerosols -- particularly black carbon and dust -- likely cause as much of the glacial retreat in the region as greenhouse gases via this "heat pump" effect.

NASA Launches Web Site for Teenagers That Want More Class
NASA has launched a new Web site created specifically for teenagers that provides teens access to current NASA spacecraft data for use in school science projects, allows them to conduct real experiments with NASA scientists, and helps them locate space-related summer internships.
Called "Mission:Science," the site is designed to showcase NASA's educational science resources and encourage students to study and pursue careers in science, technology, engineering and math, or STEM.
"This site will allow teenagers, who have their own unique language and style, to get information faster and have fun at the same time," said Ruth Netting, manager of education and outreach activities in NASA's Science Mission Directorate at NASA Headquarters in Washington. "NASA provides a vast amount of STEM information online for students of all ages, but this Web site boosts the content available for this age group."
The site also features social networking tools, links to enter science contests or participate in a family science night, information about college research programs, and an array of NASA images, animation, videos and podcasts.
NASA's Science Mission Directorate studies Earth, explores the planetary bodies of our solar system, examines the sun and its influence throughout the solar system and scans the universe to gauge its expanse while searching for Earth-like planets. To access the Mission:Science Web site, visit:
