Had to cable up some old HDD’s and made a few interesting discoveries – GISS around 2000 made an attempt to adjust for UHI contamination using a long tapered adjustment – which in retrospect was probably one of the better attempts by any of the big IPCC climate groups to deal with UHI.

Dr. Ronan Connolly has sent me their paper Urbanization bias I. Is it a negligible problem for global temperature estimates? R. Connolly, and M. Connolly (2014). Open Peer Rev. J., 28 (Clim. Sci.), ver. 0.1 (non peer reviewed draft). A quick read through has impressed me sufficiently that the authors can be a force to [...]
Or did this pattern arise by chance. There have been various papers over decades claiming rain can be enhanced by urban areas. I drew attention to a similar pattern for Melbourne Christmas 2011. BoM Australia Rainfall and River Conditions page where you can drill down for rain over the last 48hrs. Even the next hour [...]
I have just been told by the Parliamentary Secretary to the Minister for the Environment – Senator the Hon Simon Birmingham – that when _ “…the Bureau publishes relevant records of weather and climate occurrences and extremes based on observations from sites around the country.” The BoM is “…taking into account any urban heat island [...]
I see Anthony Watts article on a new paper in Theoretical and Applied Climatology – “Effect of data homogenization on estimate of temperature trend: a case of Huairou station in Beijing Municipality”. Thanks to Springer for making this paper open access. My point here is that this diagram which shows how UHI warming gets fixed [...]
The mainstream media TV weather news and press has been spouting the Bureau of Meteorology (BoM) claim that July was the warmest ever in Canberra with a mean monthly max of 13.3. Yet you only have to check early 20th Century data from Queanbeyan to see the claim is dubious. Data from BoM. Queanbeyan recorded [...]
I was interested in this Sydney Morning Herald article with various statements about recent warm conditions in Sydney. When you search for the headline – Cooler weather to mark start of winter – at the SMH website you get this intro text at the link – “Another warm month makes the last 12 the hottest [...]
An interesting call because Perth Regional Office weather station 9034 never recorded a minimum of 0°C for any month in all the years 1897-1992, see my table below. Chris Gillham has an account of the history of the various locations for Perth weather instruments. BoM forecast late afternoon 30 May 2013 – From 1993 and [...]
Matt Ridley’s page “The greening of the planet” lead me to the work of Professor Ranga Myneni of Boston University. A page listing his publications has a link to this 2012 paper – “Surface Urban Heat Island Across 419 Global Big Cities”. Peng et al., 2012 Surface Urban Heat Island Across 419 Global Big Cities, [...]
Just came across this concise article at the Arizona blog WryHeat – Urban heat island effect on temperatures, a tale of two cities – Authored by Jonathan DuHamel. We need more examples defining the UHI out there all the time to counter the colossal IPCC compliant propaganda.
Over a decade ago I posted this page [...]
