Japanese scientist Kyoji Kimoto proposes that there is a long standing error in IPCC AGW theory.
According to IPCC’s AGW theory,Climate Sensitivity CS (With Feedback WF) is expressed as follows.
CS(WF)=CS(No Feedbck NF)x(Feedback effects)=1.2K x 2.5=3K
In IPCC theory, it is the most important postulation that CS(NF) is 1.2K,
which is based on Cess’s calculation having mathematical error – for details downbload 76KB 6 page pdf report.
From energy budget of the earth,CS(WF) is 0.2-0.5K instead of 3K,
which coincides with obsevational CS(WF) of 0.2-0.8K by other methods.

Saw this gem headlined – Sudden stratospheric warming responsible for UK’s icy blast – which contrives to blame cold wintry conditions on warming without mentioning (in 475 words), that the temperature fluctuations in the stratosphere are associated with migration of the jetstream.
But if you listen to the video explanation by Peter Gibb you will see he does refer to the polar jet.
BBC readers in a hurry who just scan the headline and move on without taking time to watch the video could take away a message that would please the IPCC.

That is a big call – like many I have been watching the SOI unable to make up its mind. Anyway – read what the Bureau of Meteorology is saying.

This has been sent in by Dr Douglas Hoyt to promote discussion – what do readers think?
The greenhouse effect works by having an additional CO2 molecule absorb radiation and re-emit it back to the surface resulting in a net warming of the system.
The anti-greenhouse effect works by having an additional CO2 molecule being struck by an oxygen or nitrogen molecule which -
1) excites the CO2 molecule which then, in turn, emits radiation, some of it to
space, resulting in a net cooling of the system.
2) The oxygen or nitrogen molecule has lost energy in the process, so is now slower, which is how the cooling is manifested.
Increased greenhouse gases have an absorber/heating function and an emitter/cooling function. It is not clear if the two functions are perfectly balanced but they should probably both be about the same.
The presence of both processes happening could provide an explanation for absence of the tropical hot spot. It could also explain the fact that the effective temperature of the earth has remained at about 255 K to within the accuracy of the measurements ever since it has been observed by satellites.
I haven’t seen any mention of the anti-greenhouse effect in any discussions. If one performs the greenhouse calculations with an instantaneous doubling of CO2, you will overlook the anti-greenhouse effect. This plot at – THE HOCKEY SCHTICK – is supportive of the above remarks.

They say – “We, the undersigned, respectfully request that NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites. We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.”
Thanks to Marc Morano for the tip.

This global “cold snap” looks more significant than the one we highlighted last month.

I mean the current trace is further below the skein of annual traces than it was in January.

Thanks to Dave for the heads-up. Another post in the “Must be due to G-l-o-b-a-l W-a-r-m-i-n-g” series.

This University of Alabama at Huntsville web page where you can graph daily NOAA satellite temperature data – for various altitudes – over the last decade – shows clearly that Earth has just entered into a series of coldest ever days at 14,000 feet altitude – since 2002 that is.

Amazing – get your own download here – looks to be 5000 emails plus other files. Looking forward to hearing about any interesting mails you find.
I have been told of this gem from the Jo Nova site.
<601> “David Jones”
subject: RE: African stations used in HadCRU global data set
to: “Phil Jones”
Thanks Phil for the input and paper. I will get back to you with comments next week. Fortunately in Australia our sceptics are rather scientifically incompetent. It is also easier for us in that we have a policy of providing any complainer with every single station observation when they question our data (this usually snows them) and the Australian data is in pretty good order anyway
No doubt there will be huge discussion on these 5000 odd emails for months to come around the blogs – links on right.
