What integrity is there in global SST trends ?

I made this map of sea surface temperature (SST) trends at the GISS website module, and it shows the 27 year trends 1979-2005 for an SST dataset GISS names HadReyn_v2 which I take in to mean the Hadley Centre version 2 SST’s with Reynolds data grafted on post 1982.

There may be another explanation of exactly what the dataset is but for sure it is the SST data Jim Hansen’s GISS group chooses to use.

I have annotated several warm anomalies that caught my eye and have compared UAH satellite trends over those warm patches with the the combined land sea HadCRUT2 data calculated at www.co2science.org.

See the Table for stunning differences in HadCRUT2 minus MSU, up to 1 degree C in 27 years !! The table also sets out the Lat & Long for various five degree grid cells that include these warm SST patches. For some history of the development of the SST datsets go to my page showing graphics of huge corrections required in raw SST data.

Weird ABC article: “High summer temperatures predicted”

High summer temperatures predicted

A leading climatologist says there is no evidence Australia will suffer from heat waves like those currently in Europe.

Dr Janette Lindsay, from the Australian National University, says there is no link between seasons in Australia and the Northern Hemisphere.

But she says Australia may be in for a warmer-than-average summer.

“The situation in Australia is very much a function of first of all what happens around the Pacific Ocean in regards to El Nino specifically,” Dr Lindsay said.

“All of the forecasts for El Nino for the coming spring and summer are that we’re looking at probably neutral, average conditions across the Pacific, maybe tending to be slightly warmer than usual.”

Dr Lindsay says Queensland and New South Wales can expect a dry spring as a result of recent temperature rises in the Indian Ocean.

“It’s likely to be drier than normal in Queensland and northern New South Wales over spring, and that also the rather mild temperatures are likely to continue and it may be warmer also in eastern Australia in spring,” she said.

FOR IMMEDIATE RELEASE

Temperature difference shows climate science not settled

A major difference in measurement between NIWA and the international body IPCC, concerning New Zealand temperature trends contradicts the assertion of the Minister for Climate Change, David Parker, that climate science is “settled.” This claim has been made by an expatriate New Zealand earth scientist, Warwick Hughes, now living in Perth.

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

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.
History of disaster deaths in Australia
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.

Jones vs MSU trends 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.
