Why are those climate scientists going around spoiling everybody’s holiday season with their doom and gloom alarmist rhetoric? For instance, this blog recently noted an observation by Alden Meyer of the Washington-based Union of Concerned Scientists griping that the Copenhagen accord lacked specific emissions targets.
And, why is that such a big deal, last minute shoppers? “If you look at what is likely going to be listed in the annexes, you are going to be well over a 3.0 C,” says Meyer.
“Big deal,” you say, “so it’s going to get a little warmer than those cold Ivy-tower types like. Big Deal.”
What was that?”
Just some cymbals clashing, nothing… really, go on with your denial.
Yes, to go along with the timpani. (Thunder and lightening, very, very frightening.) You were saying?
World Meteorological Organization and NOAA both report that 2000-2009 is the hottest decade on record. It is the consensus of climate scientists that we have yet to see the effects of GHGs already in the atmosphere.
“No, I want to know what’s with the cymbals AND timpani?”
As previously noted, there is more than one. You were paying attention, yes? Let’s repeat, just in case.
Following a decade of relative stability, for example, the atmospheric concentration of methane (CH4), a potent greenhouse gas, began to rise inexplicably in 2007. Although deteriorating permafrost has been observed in Russia, Sweden, and Tibet, the precise source of the increase has not yet been identified.
As permafrost melts and the depth of its active layer deepens, organic material begins to decay. If the surface is covered with water, methane-producing bacteria break down the organic matter. Such bacteria cannot, however, survive in the presence of oxygen; if thawed soils are exposed to air, carbon dioxide-producing bacteria participate in the decay process. Both events amplify the effects of warming temperatures by releasing greenhouse gases. The likely magnitude of such a positive feedback, which is considered to be a potential tipping element, is unknown.
And, as AG readers well know, “methane is the second most important contributor to global warming behind carbon dioxide, though its abundance in the atmosphere is far lower. Additional methane traps twenty one times more heat over 100 years than the same mass of carbon dioxide (CO2 ).”
“Baring Head station showing that southern hemisphere atmospheric methane increased by 0.7% over the two-year period 2007–08. While this increase may not sound like much, it is about 35 times more than all the methane produced by New Zealand livestock each year.”
That is why those climate scientists have been a bit snippy of late. “The evidence we have shows that methane in the atmosphere is now more than double what it ever was during the 800,000 years before 1700AD” says NIWA Principal Scientist, Dr Keith Lassey. “This is based on analyses of ancient air trapped in polar ice that has been extracted and dated.”
“(Sound of flatus)”
Yes, when I was a kid I used to think the kid who could make that sound with his hand and armpit was quite talented.
“Sorry, must have been the kangaroo bangers. I can roll my tongue up, too. Bet you can’t do that?”
No, and I get the point. Genetics — Adaptation.
“Well, you science types are always on about Evolution.
True, and Evolution is in response to another force… Extinction. Have a good time shopping.
