Fascinating that the Southern Hemisphere continues this habit of not warming as much as the north.
Does anybody know of comment out there casting light on the reason for this growing divergence in recent months ?

US expert finds hurricane intensity under-reported in early years
This article from news.com.au is timely just after my post re a drop off in Australian deaths from climate disasters.
This is the Dr Chris Landsea who resigned from the IPCC some time ago because he was not being listened to. Heavens above, why would anyone expect the IPCC to listen to an expert. Continue reading US expert finds hurricane intensity under-reported in early years
New Zealand group sceptical of IPCC science
The New Zealand Climate Science Coalition NZCSC had a good week with media comment on their open letter to MP’s calling for a Royal Commission into IPCC science and how it is affecting the NZ economy.

Typical media comment was an article in the NZ Herald. Continue reading New Zealand group sceptical of IPCC science
Carbon dioxide and warming
“Thus adding carbon dioxide to the atmosphere warms it a bit and leads to more water vapour and hence more warming.”
This is a direct quote from the New Zealand climate authority NIWA, in a media release after the formation of the newly formed ‘New Zealand Climate Science Coalition’ in May.
This NIWA statement sounds to me like early 1990’s IPCC inspired scares about a positive feedback and the threat of runaway warming. Is it not obvious that climate history of the last million or so years is one of repeated runaway COOLING, lurching the planet into a series of ice ages. I see no evidence for runaway warm periods, so it is obvious that the climate system incorporates feedback mechanisms that largely negate the effect NIWA is trying to express.

Long term reduction in Australian deaths from, bushfires, cyclones and heatwaves.
The data for this graphic is sourced from the Emergency Management Australia (EMA) online Disasters Database. www.ema.gov.au/ema/emaDisasters.nsf
Added 8 August, I have just heard of this 2006 report by Dr Indur M. Goklany of the US Dept of Interior, “Death and Death Rates Due to Extreme Weather Events: Global and U.S. Trends”, 1900-2004. See entries at the Roger Pielke Snr Blog.
Interesting that huge reductions in all categories of deaths are against a greatly increased population compared to pre WWII.

Is massive UHI warming in China distorting Jones et al gridded T data ?
A recent paper discussing long term temperature trends in China presents a graphic of century long trends including the Jones data.
“ZHAO Zongci, DING Yihui, LUO Yong, and WANG Shaowu, “Recent Studies on Attributions of Climate Change in China” , Acta Meteorologica Sinica 2005, Vol 19, 389-400.”
The caption refers to four trends from various sources being coloured but my copy was B & W. Anyway, it is clear there is much agreement and what really tweaked my interest was the strong warming post 1970.
Using the gridded data downloadable from www.CO2science.org comparisons have been made between the Jones data and the UAH / NASA satellite MSU data for the period (1979-2005). Results in Table A for a block of eight grid cells covering much of Eastern China were quite stunning in revealing a difference of 0.96 degrees C for the 27 year period 1979-2005.
Can anyone have any doubt that the reason for this huge difference is in fact the influence of rapidly expanding UHI warming on China weather station data?
Similar experiments were repeated over Europe, Central Asia / Russia, Sahara to Iran(added 18 Aug) and New Zealand. Results are set out in Table A and reveal a stark contrast to the blizzard of pro-IPCC views in recent times that global temperature datasets from the surface and lower troposhere are now in substantial agreement following corrections by the UAH team.
Any agreement in global trends between the various datasets is probably due to the averaging of various errors from here and there to give an appearance of agreement.
Wegman on “Dueling Weblogs” and Information Asymmetry
John A: I would like to emphasize that the following is my personal view and not necessarily that of Steve McIntyre or Ross McKitrick.
In amongst the consideration of the proxy, statistical and social network evidence of the Wegman report, there is also this (page 48), which I could construe (albeit distantly) as a personal criticism:
5. As mentioned in our introduction, much of the discussion on the ‘hockey stick’
issue has taken place on competing web blogs. Our committee believes that web
blogs are not an appropriate way to conduct science and thus the blogs give
credence to the fact that these global warming issues are have migrated from the
realm of rational scientific discourse. Unfortunately, the factions involved have
become highly and passionately polarized.
