Graham Readfearn | Australians Beware: Soon The Climate Science Deniers Will Be In Charge
ANYONE who places stock in safeguarding the current and future climate (and for that matter anyone who doesn't) should prepare themselves for the risk that very soon, climate science deniers, contrarians and sceptics will be running the show.

All the polls suggest that a Liberal-led coalition will sweep to power at next year's Federal election in Australia - the world's biggest exporter of coal and on track to be the biggest exporter of liquified natural gas.
Subsidies Row: Green Energy Is Turning Into A 'Political Risk'
Delays and political interference in the setting of subsidies for wind farms may deter investment in the UK, energy companies have warned.
Smaller 20th Century Warming: Hotter Medieval Warm Period
Anyone who has seen the raw temperature output from a weather station must have wondered at the marvel of averages. The output is all over the place – large fluctuations in temperature from hour to hour and day and night. Yet from those measurements the result is just one number – the monthly average – that finds its way into climate data.

Picking meaningful information from the variable set that are weather stations often seems more art than science; truncated sequences, gaps, changes of equipment, changes of sites, changes in the local environment, to name but a few factors that have to be taken into consideration, or sometimes not taken into consideration.

A new analysis of some of the statistical methods used in getting something out of temperature readings from weather stations carried out by Steirou and Koutsoyiannis of the National Technical University of Athens has been gaining some publicity as its conclusions are startling. The researchers say that the statistical manipulation of the data to correct errors often introduces even greater errors, as well as exaggerating positive trends.
