If strong winds are behind the pause in global warming – would weaker winds cause global warming?

According to the ABC – a recent article by Professor Matthew England University of New South Wales – has claimed – “…stronger than normal winds in the Pacific are the explanation for a pause in global warming…”
I just thought I would open this for discussion here.
Does anybody know of long term land based wind observations in the tropical Pacific.

Another example of a possible drift in early TOMS satellite ozone data

I have looked at the ozone hole issue a few times over the years – and have had a suspicion that various factors affect stratospheric ozone levels apart from destruction wrought by gases released from old fridges and freezers.
In the previous post the graphic indicates that ozone and temperature could be more congruent in the early years 1978-1985.
Out of curiosity I compared TOMS monthly data ex KNMI to the Arosa ozone series from Switzerland.

Lo and behold – TOMS numbers look too large in the early years too.
The KNMI TOMS series is a blend with more recent data from the European Space Agency SCIAMACHY ozone data. TOMS having ended in 2007.

Linking the origins of Typhoon Haiyan to warm sea surface temperature anomalies is far from convincing

The Sydney Morning Herald ran this article – Typhoon Haiyan influenced by climate change, scientists say – there must be hundreds of articles written along the same general drift. In this case a map of sea surface temperature (SST) anomalies is presented by the SMH for the period 3rd to 5th Nov.

Note the location of the warm anomaly is from 160-165 East and between 5 South & 5 North.
Here is a map of Typhoon tracks including the Haiyan path extended as far east to its origins as I can find.

Note that Haiyan originated in the grid box 155-160 East and 5-10 North. A fair distance from the grid box where the weak SST anomalies highlighted in the SMH article were supposed to cause the Typhoon to form.
Note also that the storm moved westwards to near 145 East before the windspeeds attracted attention and the Typhoon was reported.
At this NOAA site you can make SST anomaly maps for 3 or 4 day periods and personally I am not seeing SST anomalies that stand out as being exceptional in late October – early November.
I have been looking for an animation of the jet streams in that region, no luck so far. I thought this page was interesting discussing the Madden-Julian oscillation.

Proposal that there is a long standing mathematical error in IPCC’s AGW theory

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.

BBC article explaining UK cold – blames warming stratosphere but can not mention j-e-t-s-t-r-e-a-m

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.
