After UN IPCC “global warming” was birthed over 30 years ago by the Gnomes of Norwich with datasets polluted by almost every city on Planet Earth – the UKMO finds 1.7 degrees UHI warming in UK wide minimum temperatures. There is an easily downloaded 5Mb pdf linked to at Watts.

Reprising satellite images of urban heat islands UHI from USA
Geoff Sherrington has a long blog on UHI and Australian temperature data “The Climate Sciences Use Of The Urban Heat Island Effect Is Pathetic And Misleading” over at Wattsupwiththat.com
A late comment by Ron Long December 21, 2018 at 3:21 am mentions “…I am totally confidant a UHI signal can be identified from satellite data.”
All done two decades ago in the 1990’s. But I think the “climate wars” have caused most of this work to be shelved and often links are dead. A 2005 blog of mine shows the famous NASA Hotlanta image – a ~2000 page of mine – Hotlanta from 2001 – Florida UHI’s – 
– a few surviving NASA pages – 3 NASA UHI pages under “Land Surface” now dead links – 2015 NASA pages with full USA image – Recent looking pages – many various subjects but I found no UHI – I have never seen satellite UHI images from Australia or anywhere but the USA.

Record cold possible for Auckland
Never mention the ever growing and expanding urban heat island UHI – Record low temperatures possible in Auckland, Northland. Remembering walking to school in Glen Eden barefoot ~1950 through hard white frosts I would be amazed if readings would not have been below -1.5.
Ignored record cold morning in NSW 27 March 2018
If it had been a hot March day with similar records this proof of “global warming” would be trumpeted far and wide. Large map
Braidwood 69132 read -0.6 breaking -0.4 from 1995.
Goulburn AP 70330 read -0.8 breaking -0.1 from 1992.
Orange AP 63303 read -0.5 breaking -0.01 from 1997.
also breaking 1.0 at the Ag Inst. 63254 from 1979
Grenfell 73014 read 2.8 smashing 3.5 from 1971.
Tuggeranong 70339 read 0.5 lowest since station opened 1996.
West Wyalong Airport AWS read 4.9 breaking 5 in 2001,
also breaking Wyalong Post Office (closed 2015) 5 from 1983 data from 1965.
All against urban influences.
The 24th March 1967 was a prominent cold day in the records.
ABC Four Corners maybe worst show ever
My phone had been running hot saying I had to watch this Four Corners expose of “climate change” – what a pageant of old wives tales mixed with assorted lies and exaggerations.
Starting with the “Braidwood drought” was a dud move due to rain and floods a week or so ago in the region – so that should have been cut. Surely the show has staff that are half awake?? I mean Canberra flooded!!
To use a vineyard near Adelaide as evidence of GW? – not even a pic of the weather instruments – Adelaide is barely a half degree warmer than 100 years ago despite the ever expanding urban heat island and electric instruments vs mercury in glass. Interesting too how the variation in the years has narrowed last ~decade.
How did the show choose to beat up heatwaves in Perth in the face of two cool summers as reported by – themselves!
Great shots of Perth Govt staffers having a day off work learning about heatwaves.
Perth watercrats turned to seawater desal in the face of plentiful water which would have offended the Greens to harvest. I list 6 sources where the WA Govt could easily have bolstered water supplies and avoided the energy intensive water factories the State is now stuck with for life. Once you get seawater desal you get the compulsory climate lies for life too.
Sorry ABC the urban heat island is not mysterious
More GreenLeft deception re the urban heat island UHI.
The UHI was recognized in Ancient Rome.
200 years ago Luke Howard published masses of detailed data on the London UHI.
Thousands of scientific papers have been published – books have been written – no mystery.
When Global Warming was birthed in the 1980’s databases were majority cities all loaded with UHI and GW was mostly UHI warming.
UHI’s can be detected and mapped from satellites.
Now global warming data has bloated to tens of thousands of temperature stations but is still loaded with UHI affected cities and GW is still mostly UHI warming.
Our BoM has published evidence detecting the UHI in small country towns.
50°C in Sydney region 1939 – perspective on recent heat
Last Sunday 7 Jan 2018 Our ABC reports the BoM – Sydney hits its highest temperature recorded since 1939 with Penrith reaching 47.3C. The BoM had just belatedly found that RICHMOND RAAF 067033 hit 47.8 on 14 Jan 1939. But there is much more to the history of hottest days in Sydney. There was another site recording at Richmond in 1939; John Tebbutt’s historic Observatory which recorded 122°F or 50°C on 11 Jan 1939 as reported in the Windsor and Richmond Gazette Fri 13 Jan 1939 Page 3 Sweltering Week Sets New Hawkesbury District Record.
In Jan 1896 there are a multitude of reports of a stunning and deadly NSW heatwave summarized by Lance Pidgeon at JoNova and picked up by the UK Daily Mail – How a 24-DAY heatwave on Australia’s east coast in January 1896 saw temperatures climb to 49 degrees and killed 437 people. The Windsor and Richmond Gazette for Sat 18 Jan 1896 Page 6 Hawkesbury Heat – On Monday 13 Jan 1896 John Tebbutt’s Observatory recorded 118.8°F or 48.2°C – also well clear of the 47.3 at Penrith last Sunday. There is a report in The Daily Telegraph Sydney,
for Tue 14 Jan 1896 Page 5 123 IN THE SHADE AT CAMDEN. But we have no information re the thermometer exposure. I wonder what readers can find. The upshot seems to be that the 47.3 at Penrith last Sunday was only a run of the mill very hot day for the Sydney region. And even less notable when you take into account the ever growing urban heat island and the fact that Penrith records one second intervals in a modern electric AWS which must produce hotter spikes than a slower acting mercury in glass thermometer.

Utter hypocrisy in urban heat island UHI articles
I see another edition in scaremongering articles about the UHI “Deadly mix of heatwaves and humidity could make some Australian cities virtually ‘uninhabitable’” cry me a river – Nobody asks “where has global warming/climate change been mostly measured these last 150 years?”
