A record is set for Antarctica’s ice (1)
A truth inconvenient, but this will suffice. (2)
To nix the decision
“Curb carbon emission” (3)
CO2 is the gas to grow corn, wheat and rice. (4)
(1) The total ice cover in Antarctica set a new all time record. According to NOAA’s Sea Ice Extent it turns out day 265 set an all time record, and then day 266 (Sept 22nd) broke that record. Days 265 through 270 are now the 6 highest Antarctic Sea Ice Extent’s of all time (in the satellite record)! 11 of the top 15 extents are now in 2012.
(2) A) In the Antarctic, at the time of maximum sea ice extents, the “edge” of the sea ice very closely approximates a “crown” around the continent between latitudes 60 south and 62 south. At those latitudes, ANY increase in Antarctic Sea Ice extents will significantly increase energy reflections from the ice, and reduce the absorption of energy from the sun into the newly covered ocean waters. The result – of ANTARCTIC sea ice maximums expanding – is increased heat loss from the earth into space, and decreased global temperatures.
B) In the Arctic, on the other hand, all of the sea ice is now concentrated in a single “Beanie” cap around the north pole. This cap can be very closely approximated as a cap extending from the pole down to latitude 80 degrees (for 4 million km^2 sea ice) or to 81 degrees for today’s 3.4 million km^2 sea ice extents.
However, at those very high latitudes, during the time of minimum sea ice extents at the equinox, more energy is lost from the exposed ocean surface by radiation into space and evaporation (both of which will begin as soon as the sea ice “insulation” is melted out) than is gained by the ocean surface absorbing sunlight. NOTE: This effect, the reverse of the conventional CAGW alarmism about sea ice albedo! – is ONLY true for the far north latitudes. But, then again, those are the only latitudes where sea ice exists at the present minimum, so it is pointless and distracting and wrong to worry about any other latitudes …. FOR ARCTIC SEA ICE.
(3) Conventional “wisdom” according to IPCC dictates that there is a strong positive feedback between CO2 levels and global temperatures, so that a doubling of CO2 would yield a global temperature increase of between 3 and 5 degree Celsius. If there was no gain in the system, a doubling of CO2 levels would cause a 0.9 degree increase. However, there is a strong negative feedback due to changes in the cloud cover and associated thunderstorms so the net effect is an increase of the global temperature of no more than 0.3 degree C. This can be verified by calculations using a simple observation of the earth’s temperature response to the varying amount of solar influx in the Northern and Southern Hemisphere over a year.
(4) For every doubling of CO2 levels the trees, plants and grass will increase their growth by 30 to 70% dependent on the species. This effect will level off at about 1200 ppm, so we can use this effect to feed an additional two billion people, or alleviate the starving that is already occurring.
Conclusion: We need more CO2, not less, to help feed the world and stave off the coming Ice-age for a little longer.
