Elevated carbon dioxide may impair reasoning
Carbon dioxide has been vilified for decades as a driver of global warming. A new study finds signs that CO2, exhaled in every breath, can exert an equally worrisome threat - impaired cognition - in nearly every energy-efficient classroom, meeting hall or office space.

Well, we now have an explanation for the rise of denialism. They must have poorly ventilated caves.

Now we know why LessFact insists that forty is spelt with a U, hence his nickname, Mr Undoubtably Spelt Fourty.

THREE pieces of info:
'steenking piddling diddling middling mudling mudslinger brian_g stumble butt dumpster diver' advocates for 500+ppm CO2 levels & stated that 1000ppm is better.
What ever the normal level of CO2 is, ambient levels in small confinements can readily be double, triple or more TIMES those levels.
We know that 'brian_g stumble butt dumpster diver' has errors of 73 million TIMES, 1 million TIMES, 1000 TIMES, & 3000 TIMES.
It is obvious, even from a non-AGW point-of-view, that higher CO2 concentrations have terribly restricted the IQ of 'brian_g stumble butt dumpster diver'. He has only been able to communicate with 'dirtling(earthling has no brain)'. His desperate desire to add more CO2 to the atmosphere is clearly an attempt to get others to lower their IQ's so they might communicate more readily.

Arctic sea ice extent is 11,208,125 km2 (December 15, 2012), the day's gain, less than W.Virginia-sized.Present temperatures on Arctic Canadian islands, mainland, & Siberia are to minus mid-thirties degC. FairBanks is -42degC. Average temperatures above the 80th parallel have plunged to -28degC.
The sun has been unseen from the North Pole for 12 weeks! Arctic Ocean warmth is & will continue to keep Arctic sea ice thinner through the coming winter & even spring. As of November, Arctic sea ice VOLUME is ~21% lower than any other year Arctic sea ice yearly VOLUME. Average Arctic sea ice VOLUME during November for the period 1980-89, was ~18 thousand km3. Present November 2012 sea ice VOLUME is 6200 km3. The Arctic sea ice loss has been an uncontrolled plummet, desired by unscientific AGW deniers, who mostly have no or little mathematical or science background.
Presently, Arctic sea ice extent is 11,234,688 km2 (December 16, 2012), the day's gain, Massachusetts-sized. Present temperatures on Arctic Canadian islands, the mainland & Siberia, are to the minus mid-thirties degC.
Continued cold along Canadian islands has caused west Baffin Bay to ice, altho the eastern Bay along Greenland remains thinly clear!!!!!! Temperatures across Baffin Bay dramatically drop, east to west. Due to solar heats absorbed into the shallow waters of Hudson Bay, the Bay has resisted icing. With past temperatures as low as -40 degC, due to cold spillage from the North Pole, the Bay has iced over, except for the small southeast.
Long resisting the Arctic Ice Pack, Chief Joseph Land is now widely encircled by Arctic Ice Pack, due to 24/7 hours of darkness & a shifting but long enduring vortex, that moved cold Arctic sea water southward to the islands. However, with a vortex near by, a patch of fairly large ocean water has opened up within the encirclement. During my reports, a vortex has generally led to Arctic Pack Ice advancement. In this case, it appears to be the opposite. Svalbard, also in winter darkness 24/7, is still clear of the Ice Pack, as is Novaya Zemlya,!!!!!!!!!
A detail noted a month & a half ago, is a raggy taggy developing edge along a part of the semi-circle Ice Pack, possibly NOT coincidental with the HUNDREDS OF THOUSANDS (plus?) OF SQUARE KILOMETERS, of waters north of Alaska & Siberia that are VASTLY CLEAR. Might the raggy taggy edge indicate huge turbulence & currents in this largest(ever?) ice free, & resulting southerly-directed heat stratified Arctic waters? I wonder if there might develop more raggy taggy edging, enough to form a swirl pattern?
Near the raggy taggy Ice Pack, developed 3 tiny pixel ice floes(arced?), separated from the Arctic ice pack toward southerly directions. A day later, the number of ice floes increased to 8 & indeed they formed an ARC. Pretty sure they represent a large scale vortex in open Arctic water!
Further data, showed that the vortex was true!
The sun has been unseen from the North Pole for 12 weeks & presently anywhere above the 67th parallel, now shrouding the Arctic with darkness for a good portion of the year! The sun is less than one third arcdeg above its farthest position to the south, due to the tilt of the Earth & present orbital position!
