On the night of the 11th-12 of Jan 2010 Melbourne sweated through an uncomfortably hot night. Just a couple of media refs will give you the gist but Google could find more no doubt. There is talk of Melbourne’s “..equal hottest night ever.” But I see no sign of balancing statements which should have refered … Continue reading How can it serve the Australian national interest by having the BoM mislead us ?
Canberra/Queanbeyan is a sprawling collection of suburbs population 300,000 plus – which extends over 30km north south and nearly 20km east west. Canberra was selected as the Australian Federal Capital early last century and urbanisation would have started after the “old” Parliament House started operating in the late 1920’s. The post WWII boom in Australia … Continue reading Evidence for a strong urbanization signal; 0.3 degrees C per decade in Canberra Airport temperature data 1997-2009
Article by Alan Moran pointing out that the behaviour of pro IPCC scientists as revealed in the Climategate emails, is nothing new. There is much to tell about the BoM of the early 1990’s. The Balling, Idso and Hughes. 1992 paper “Long-Term and Recent Anomalous Temperature Changes in Australia.” – referred to in the ABC … Continue reading Some rare balance on the taxpayer funded ABC for a change
The brave prediction, “Sydney’s climate to ‘become like Brisbane’s’” for 2100 by staff at James Cook University means that Sydney Airport will warm by ~2.75 degrees C relative to Brisbane Airport (based on 1961-1990 averages) for this prediction to come true. It is obvious that the Sydney Urban Heat Island (UHI) has already notionally moved … Continue reading More huge errors in HadCRUT3 gridded temperature data
I first got to know the BoM in 1991 when GW was in its infancy and was surprised at the extent to which PC myths coloured peoples thinking. I noted very early on that many long term small town sites were as warm in the 1880’s as they were in the 1980’s and when I … Continue reading Some early contact with bias and mythology in the Australian Bureau of Meteorology BoM near two decades ago
Ren et al 2008 measure urban warming in a north China grid box 33 to 43 degrees North and 108 to 120 degrees East by comparing temperature trends in groups of stations of different population size for the period 1961-2000. For a concise summary of the Ren et al 2008 paper, Urbanization Effects on Observed … Continue reading Chinese climate scientists tactfully tell the IPCC that surface air temperature (SAT) trends over north China include a large component of urban warming
THESE days, it can be hard to imagine how Melbourne ever earned a reputation as the gloomy, rain-filled capital of the south. But, growing up in the 1970s, my memories are full of muddy ovals, local creeks in flood and catching tadpoles in puddles that lasted for months on end. How things have changed.Since 1996, … Continue reading “Our hot, dry future”?
Last year I posted “San Juan Puerto Rico, EXACTLY how UHI warming can get into global gridded T trends” . I should have added this Fig 4 from Duchon’s 86 paper that I refer to. There is IPCC AGW shouting out from the UHI affected San Juan trend, incorporated by Jones et al and the … Continue reading True temperature trends for Puerto Rico hidden in fragmented data
Philip B commented on “Climate predictions “right only half the time”” Warwick you wrote: Since the nighttime temperatures are rising three times as fast as the daytime temperatures (Karl et al., 1993), it implies a non-climatic signal in the nighttime data equal to about one half of the total warming. It implies the reported global … Continue reading Daily temperature range (DTR), max minus min, some ramblings
At ClimateAudit, Steve McIntyre has a Feb 19 2007 post ” Jones and the Russian UHI”, tackling the issue of replicating what was done in the highly influential Jones et al 1990 Letter to Nature. See my rebuttal of this pivotal Jones et al 1990 Letter to Nature at: www.warwickhughes.com/papers/90lettnat.htm Steve recounts how years ago … Continue reading Does anybody have a very detailed list of Russian met station locations ?
