More on recorded temperatures

I blogged before about surface recording stations. If urban growth has appeared around them over the years, the temperatures they record will become higher over time - hey, that's warming.

Now John Ray has picked up a report about Australia.

"Professor Lance Enderbee has published graphs of mean temperatures from 27 rural recording stations in Australia for 100 years from 1890 to 1990. The trend is horizontal, with mean temperature in 1990 below that for 1880. This has occurred during the century of the motor car, two world wars, and massive growth of coal burning for steel production and power generation. Rising carbon dioxide levels have had no effect on temperatures". "A similar data set for six Australian capital cities shows a generally rising trend in temperature since 1950 - that is, rising temperature in Australia is an urban effect, not a result of carbon dioxide in the atmosphere."

John has added another comment about the Lockwood paper.

The Lockwood paper was designed to rebut Durkin's "Great Global Warming Swindle" film but it is in fact an absolute gift to climate atheists. What the paper says was of course all well-known already but the concession from a Greenie source that fluctuations in the output of the sun have driven climate change for all but the last 20 years really is invaluable. And the one fact that the paper documents so well -- that solar output is on the downturn -- is also hilarious, given its source. Surely even a crazed Greenie mind must see that the sun's influence has not stopped and that reduced solar output will soon start COOLING the earth! Unprecedented July 2007 cold weather throughout the Southern hemisphere might even be the first sign that the cooling is happening. And the fact that warming plateaued in 1998 is also a good sign that we are moving into a cooling phase. As is so often the case, the Greenies have got the danger exactly backwards.

So - if you believe in the greenhouse gas effect - maybe we should be pumping greenhouse gases out for all we're worth, to counteract the dip in the sun's output.
