The Hockey Schtick points to a new paper that finds a large increase in sunshine over the last 26 years.
“According to the authors, “the average increase of [surface solar radiation] from 1982 to 2008 is estimated to be 0.87 W m−2 per decade,” which equates to 2.26 W m-2 over the 26 year period. By way of comparison, this forcing was 12.5 times greater than the surface forcing alleged by the IPCC from increased CO2 over the same period.
The abstract is here. The paper is here.
“since the late 1980’s Rs has brightened over Europe due to decreases in aerosols but dimmed over China due to their increases. We found that variation of cloud cover determines Rs at a monthly scale but that aerosols determine the variability of Rs at a decadal time scale, in particular, over Europe and China.”
The warming since 1980 was caused by clean air legislation in the the US, UK and Europe.
Not by CO2.
I have posted several articles on this theme here , here and here.
The NSIDC and many other used the ozone hole as an “excuse” for why Antarctic Sea Ice Extent broke records this year.
“Both warming and ozone loss act to strengthen the circumpolar winds in the south. This is due primarily to persistently cold conditions prevailing on Antarctica year-round, and a cold stratosphere above Antarctica due to the ozone hole. Stronger winds generally act to blow the sea ice outward, slightly increasing the extent”
Guess what, WUWT tells us it was the 2nd smallest ozone hole in 20 years.
“The average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years, according to data from NASA and National Oceanic and Atmospheric Administration (NOAA) satellites.”
What a shock. The “scientists” excuses for more Antarctic Sea Ice was bogus.

The Yellow is the amount of ice where 2012 was higher than 2007.
The Pink is the amount of ice where 2007 was higher than 2012.
One of those areas is an indicator of the end of the world according to AGW. The other area is to be ignored.

Notice which years beat out September 2012 … 5 from the 1930s … 3 from the 1920s. 1897. 1906. Not much evidence of “dangerous warming” this September.
USCRN vs NOAA September 2012 update.
The USCRN is a new ‘state of the art’ United States Climate Reference Network. The USCRN “consists of 114 stations developed, deployed, managed, and maintained by the National Oceanic and Atmospheric Administration (NOAA) in the continental United States for the express purpose of detecting the national signal of climate change.”
This is the monthly Mean from both NOAA and USCRN for September 2012 for the 48 continental states.
16 states show USCRN stations warmer than NOAA (bold) and 32 show NOAA warmer than USCRN.
NOAA – USCRN = NOAA state temperature average minus USCRN state temperature average.
Ignoring area weighting, the NOAA temperature averaged 0.80F warmer than USCRN.

Antarctic Sea Ice Extent set an all time record in 2012. The previous record was set in 2006. In 2006 there were 30 days where the ice extent was over 19 million sq km. That record has not been broken and was 9 days more than the previous record holder (1998).
So what did the NSIDC have to say about it in 2006?
Nothing.
They mentioned the Arctic a lot. And Al Gore’s movie. And that there was going to be an open house. But they ignored Antarctica. If they were scientists and not propagandists shouldn’t they be interested in both poles and maximum records too?
Only 9 years in the satellite era have seen Antarctic Sea Ice Extent hit 19 million sq km. 2006 had 30 days. In the last 2 days 2012 has trend up again over 19 million and put it within 2 days of tying the all time record. Aside from 1980, all of those years have been since 1998 which some people claim have been the hottest years in the history of human beings. Antarctic Sea Ice Extent disagrees.
