The SUN Causes Global Warming???!!!
If only we had ratified Kyoto. Call Time Magazine, the NYTimes and the LA Times! Global warming is affecting Mars too!
Its gotta be the rovers, there's two of them up there and they've been operating for a lot longer than anyone thought.

This pair of images shows a dune as it appeared on July 17, 2002, (left) and as it appeared on April 27, 2005, (right). During this period, a couple of gullies formed on the dune slip face. It is critical to recognize that the 2002 image was obtained at a time of year when the incident sunlight was coming in from a lower angle, relative to the horizon, than in the 2005 image. If the gullies had been present in 2002, their appearance would be sharper and more pronounced than they are in the 2005 image. The gullies simply did not exist on July 17, 2002.
Orbiter's Long Life Helps Scientists Track Changes on Mars
(Additional images)
New gullies that did not exist in mid-2002 have appeared on a Martian sand dune.
That's just one of the surprising discoveries that have resulted from the extended life of NASA's Mars Global Surveyor, which this month began its ninth year in orbit around Mars. Boulders tumbling down a Martian slope left tracks that weren't there two years ago. New impact craters formed since the 1970s suggest changes to age-estimating models. And for three Mars summers in a row, deposits of frozen carbon dioxide near Mars' south pole have shrunk from the previous year's size, suggesting a climate change in progress.
"Our prime mission ended in early 2001, but many of the most important findings have come since then, and even bigger ones might lie ahead," said Tom Thorpe, project manager for Mars Global Surveyor at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The orbiter is healthy and may be able to continue studying Mars for five to 10 more years, he said.
Mars years are nearly twice as long as Earth years. The orbiter's longevity has enabled monitoring of year-to-year patterns on Mars, such as seasonal dust storms and changes in the polar caps. "Mars is an active planet, and over a range of timescales changes occur, even in the surface," said Dr. Michael Malin of Malin Space Science Systems, San Diego, principal investigator for the Mars Orbiter Camera on Mars Global Surveyor.
"To see new gullies and other changes in Mars surface features on a time span of a few years presents us with a more active, dynamic planet than many suspected before Mars Global Surveyor got there," said Michael Meyer, Mars Exploration Program chief scientist, NASA Headquarters, Washington.
Two gullies appear in an April 2005 image of a sand-dune slope where they did not exist in July 2002. The Mars Orbiter Camera team has found many sites on Mars with fresh-looking gullies, and checked back at more than 100 gullied sites for possible changes between imaging dates, but this is the first such find. Some gullies, on slopes of large sand dunes, might have formed when frozen carbon dioxide, trapped by windblown sand during winter, vaporized rapidly in spring, releasing gas that made the sand flow as a gully-carving fluid.
At another site, more than a dozen boulders left tracks when they rolled down a hill sometime between the taking of images in November 2003 and December 2004. It is possible that they were set in motion by strong wind or by a "marsquake," Malin said.
Some changes are slower than expected. Studies suggest new impact craters might appear at only about one-fifth the pace assumed previously, Malin said. That pace is important because crater counts are used to estimate the ages of Mars surfaces.
The camera has recorded seasonal patterns of clouds and dust within the atmosphere over the entire planet. In addition, other instruments on Mars Global Surveyor have provided information about atmospheric changes and year-to-year patterns on Mars as the mission has persisted. Daily mapping of dust abundance in Mars' atmosphere by the Thermal Emission Spectrometer has shown dust over large areas during three Mars southern hemisphere summers in a row. However, the extent and duration of dust storms varied from year to year.
Mars Global Surveyor was launched Nov. 7, 1996; entered orbit around Mars Sept. 12, 1997; and returned the first Mars data from its science instruments Sept. 15, 1997. Beyond its own investigations, the orbiter provides support for other Mars missions, such as landing-site evaluations, atmospheric monitoring, communication relay and imaging of hardware on the surface. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. JPL's industrial partner is Lockheed Martin Space Systems, Denver, which built and operates the spacecraft.

DeLay declares 'victory' in war on budget fat
House Majority Leader Tom DeLay said yesterday that Republicans have done so well in cutting spending that he declared an "ongoing victory," and said there is simply no fat left to cut in the federal budget.
Mr. DeLay was defending Republicans' choice to borrow money and add to this year's expected $331 billion deficit to pay for Hurricane Katrina relief. Some Republicans have said Congress should make cuts in other areas, but Mr. DeLay said that doesn't seem possible.
"My answer to those that want to offset the spending is sure, bring me the offsets, I'll be glad to do it. But nobody has been able to come up with any yet," the Texas Republican told reporters at his weekly briefing.
Asked if that meant the government was running at peak efficiency, Mr. DeLay said, "Yes, after 11 years of Republican majority we've pared it down pretty good."
Congress has passed two hurricane relief bills totaling $62.3 billion, all of which will be added to the deficit.
Republican leaders have been under pressure from conservative members and outside watchdog groups to find ways to pay for the Katrina relief. Some Republicans wanted to offer an amendment, including cuts, to pay for hurricane spending but were denied the chance under procedural rules.
"This is hardly a well-oiled machine," said Rep. Jeff Flake, Arizona Republican. "There's a lot of fat to trim. ... I wonder if we've been serving in the same Congress."
American Conservative Union Chairman David A. Keene said federal spending already was "spiraling out of control" before Katrina, and conservatives are "increasingly losing faith in the president and the Republican leadership in Congress."
"Excluding military and homeland security, American taxpayers have witnessed the largest spending increase under any preceding president and Congress since the Great Depression," he said.
Mr. Keene said annual nonmilitary and non-homeland security spending increased $303 billion between fiscal year 2001 and 2005; the acknowledged federal debt increased more than $2 trillion since fiscal year 2000; and the 2003 Medicare prescription drug bill is estimated to increase the government's unfunded obligations by $16 trillion.
Tom Schatz, president of Citizens Against Government Waste (CAGW), said if Mr. DeLay wants to know where to cut, "there are plenty of places to reduce."
His group soon will release a list of $2 trillion in suggested spending cuts over the next five years, and he said Congress also could cut the estimated $20 billion to $25 billion in pet projects that make their way into must-pass spending bills each year.
CAGW and the Heritage Foundation also suggest rescinding the 6,000-plus earmarked projects in the recently passed highway bill.
But Mr. DeLay said those projects are "important infrastructure" and eliminating them could undermine the economy as Congress tries to offer hurricane relief.
"It is right to borrow to pay for it," he said. "But it is not right to attack the very economy that will pay for it."
Mr. Schatz, though, said the highway bill included projects such as flowers for the Ronald Reagan freeway in California, which he said aren't essential spending.
Mr. DeLay said the budget this year was pared down and 100 programs or offices were eliminated in this year's spending bills. "We have been doing that for 11 years," he said. He said it's an "ongoing process" that will be more complete after this year's budget process, which calls for cuts to Medicaid and other entitlement programs.
Rep. Patrick T. McHenry, North Carolina Republican, agreed that Republicans "have been more fiscally sound than the Democrats were in their decades in the House." He acknowledged that "we're still trying to improve," and noted Mr. DeLay is leading the fight to reform the budget process.
"We've had a good start, but many of us want to see the government be more fiscally sound and conservative in the future," Mr. McHenry said.
