Yet another canvassing of experts’ opinions
In this survey of 5000 members of the Scottish Climate and Energy Forum, although respondents overwhelmingly agreed that human induced greenhouse gases were increasing and likely to bring warming, only 2 per cent thought the outcome would be catastrophic warming.
Warming trends reviewed
Australia’s Bureau of Meteorology and CSIRO says that due to human actions Australia will see more fire and brimstone over future decades. It concludes, “Reductions in global greenhouse gas emissions would increase the chance of constraining future global warming. Nonetheless adaptation is required because some warming and associated changes are unavoidable.” Meanwhile, Green World Trust brings us this real neat graphic series of temperature trends that put the current period into perspective. Father of the “hockey stick” claims, Michael Mann, may not be impressed since he is suing Mark Steyn, who he claims has denigrated his credentials; Steyn has lobbed-in a counter-sue claim for $30 million in costs and damages against Michael Mann.
Just to illustrate that science fashions are ever changing, John Sullivan has researched the leading climate text of 60 years ago, the Compendium of Meteorology (1951) of the AMS resource link. The particular section by Brooks, C.E.P. “Geological and Historical Aspects of Climatic Change” at p. 1016 states: “Arrhenius and Chamberlin saw in (CO2) a cause of climatic changes, but the theory was never widely accepted and was abandoned when it was found that all the long-wave radiation absorbed by CO2 is also absorbed by water vapour.”
A coolish shower to current warmist theory is delivered in a new report by IPCC authors, which finds, “climate sensitivity per doubling of CO2 most likely being under 2°C for long-term warming, with a best estimate of only 1.3-1.4°C for warming over a 70 year period”.
Business reactions to climate issues
Jo Nova explains why Warren Buffett loves apocalyptic claims since they are good for his insurance business, even though “I calculate the probabilities in terms of catastrophes no differently than a few years ago”.
Meanwhile German businesses are revolting – every sixth company has shifted off the grid to avoid paying the 22 per cent price premium required for renewable energy. And Britain’s coal producers commissioned work to examine the effects of freezing the tax floor for carbon, which is set to increase from £15.7/tCO2 in 2013 to £30/tCO2 in 2020 and £70/tCO2 in 2030 (in 2009 constant prices). Unsurprisingly the study found freezing the tax would ease price increases.
News about politicians and their hired hands
In the US the House of Representatives has blocked the administration’s plan to limit carbon pollution from new power plants.
Politicians in the Australian capital have a bold plan to provide 24 per cent of electricity from wind at a weekly cost, they say, of a mere $1.30 per household; according to the energy regulator, renewable costs in Canberra (p.89) already comprised 8 per cent of electricity costs last year.
The federal government may have a contrary view. This month the Abbott Government will announce a bonfire of regulations. Even so, the competition regulator, though having already overspent its budget, is imposing a vast new reporting regime on businesses hoping to discover over-charging for carbon costs.
And the legacy of the past fights on. Australia has a bunch of tired leftists led by Bernie Fraser on the public payroll through the Climate Change Authority promoting the combatting of what they perceive as human induced global warming. In support, there is a public funded journal, the Conversation, with a writer financially supported by the public funding (your ABC). Poison pills left by the ALP Green coalition provide taxpayer assistance to those undermining the economy and the elected government!
