WASHINGTON Carbon dioxide isn't the only greenhouse gas that worries climate scientists. Airborne levels of two other potent gases one from ancient plants, the other from flat-panel screen technology are on the rise, too. And that's got scientists concerned about accelerated global warming.
The gases are methane and nitrogen trifluoride. Both pale in comparison to the global warming effects of carbon dioxide, produced by the burning of coal, oil and other fossil fuels. In the past couple of years, however, these other two gases have been on the rise, according to two new studies. The increase is not accounted for in predictions for future global warming and comes as a nasty surprise to climate watchers.
Methane is by far the bigger worry. It is considered the No. 2 greenhouse gas based on the amount of warming it causes and the amount in the atmosphere. The total effect of methane on global warming is about one-third that of man-made carbon dioxide.
Methane comes from landfills, natural gas, coal mining, animal waste, and decaying plants. But it's the decaying plants that worry scientists most. That's because thousands of years ago billions of tons of methane were created by decaying Arctic plants. It lies frozen in permafrost wetlands and trapped in the ocean floor. As the Arctic warms, the concern is this methane will be freed and worsen warming. Scientists have been trying to figure out how they would know if this process is starting.
It's still early and the data are far from conclusive, but scientists say they are concerned that what they are seeing could be the start of the release of the Arctic methane.

FRom last night..
Potent greenhouse gas more common than estimated: study (nitrogen trifluoride)

Whale flatulence?
These GW alarmists have been kind of quiet since people figured out their scam. I guess their “fries guy” jobs didn’t work out so now they are back at it.
Not this reindeer shit again! Please!
God, I depise prostituted science!
Seems like more of that which comes from the south end of a north bound bull........
Meanwhile, back in the real world, the Arctic Ice is refreezing at record rates.

Meanwhile, back in the Arctic, life goes on the way it always has.
I’m beginning to think reposting is causing GW
I thought maybe they had been sampling downwind of me lately.
Perfect timing to get the Marxists in the District of Communism to give them our money to FIX it.
Got a cruise scheduled to Alaska next May, I’ll be checking the glaciers in Tracy Arm Fjord weather permitting.. and just tooling along thru the ice chunks and wildlife.
I may make a run to Mendenhall glacier this trip and skip the salmon, see where the glacier is today.., we visited there about 15 years ago, altho with modern technology, I can get a pretty good view right now.. :-]
doesn’t look much different today than it did then..

WHAT “global warming effects of CO2”????? This has NOT AT ALL been established, except in the demented mind of Gore and his acolytes.
That should be a nice trip.
I be leaving for old mex in a couple of weeks - where november is just like a warm spring...
“The data isn’t all in, but scientists are concerned” Oh yea!! which scientists? The IPCC? Algore, and his band of corrupt pseudo scientists? I guess CO2 wasn’t doing it for em so they invent a new scam. OMG!! we’re all gonna die! as 1 freeper pointed out, water is the biggest greenhouse gas,,,like 95%! don’t hear any mention of this fact from the goofy alarmists. makes me sick, and McCain is 100% in the tank with Algore on this phony issue. scuze me while I puke.
We need to cap and trade. Cap it with a wellhead and trade it to a power plant for cash.
LOL LOL
What a laugh....
Worry about a nuclear Iran
Taking into account the greater greenhouse potential of Nitrogen Trifluoride, it is still only 0.00038% of the atmosphere in CO2 equivalent potential (ie. why are we even taking about it.)
And Methane levels in the atmosphere have stabilized. This freaking out about the Arctic methane is completely fabricated since there is no real increase in Methane levels. There was a small uptick of 5 parts per Billion in 2007 or 0.000000005% (that’s right 8 zeros) of the atmosphere in 2007 after stabilizing for several years (most people would consider 0.000000005% to be ZERO.)
