Climate & Climate Change

Carbon Dioxide Follows Temperature: Murray Salby

By

ACCORDING to Murray Salby, Chair of Climate at Macquarie University, recent increases in atmospheric carbon dioxide are from predominately natural sources and changes in atmospheric levels of carbon dioxide follow changes in temperature. This was the thrust of the Professor’s message to an audience at the Sydney Institute last week.

No Barking Greenhouse Effect

By

REMEMBER the Sherlock Holmes story, Silver Blaze…

Gregory (of Scotland Yard): “Is there any other point to which you would wish to draw my attention?”
Holmes: “To the curious incident of the dog in the night-time.”
Gregory: “The dog did nothing in the night-time.”
Holmes: “That was the curious incident.”

And so an outraged commentator at Steven Goddard’s blog asks why we can’t observe the effects of increasing infra-red radiation…

“WHAT you have is a bunch of people claiming ever more heat in the atmosphere in form of infra-red, but the infra-red telescopy field says not one word for multiple score of years about ‘rising infra-red destroying our viewing and here’s the analysis over time’

You hear NOT ONE WORD from optical telescopy – the field that helped Einstein cement relativity’s place in history by measuring the bending of a beam of starlight by galactic gravitational bodies – not ONE WORD from the optical telescopy field which effectively holds up a microscope to the atmosphere’s heat distortion – remember the DEFINITION of HEAT on GAS is – what kids? it’s M.O.T.I.O.N.

Polish Scepticism Tempers Alarmist EU Agenda

By

“ON June 22, Poland opposed all the other EU countries to block the conclusions of the EU environmental ministers council. Were it not for Poland’s opposition, the council would have adopted stricter carbon emission targets, endorsing the commission’s 2050 Roadmap calling for a 40 percent cut in carbon emissions by 2030, a 60 percent cut by 2040 and a 80 percent cut by 2050, compared to 1990 levels.

“Just days before, Brussels audiences were shocked to hear a statement from the EU budget commissioner, Poland’s Janusz Lewandowski, who declared to national media: ‘We already have overambitious agreements on CO2 emission reduction. There is a notion that the thesis that coal energy is the main cause of global warming is highly questionable. Moreover, more and more often there is a question mark put over the whole [issue of] global warming as such.’

“Such reactions were not unpredictable for Poles: inside the largest of the new member states, scepticism towards climate change science and defiance of the EU climate and energy package has predominated in governmental and mainstream media discourses for months…

Outgoing Longwave Radiation and the Greenhouse Effect: Ken Gregory

By

Outgoing longwave radiation and the greenhouse effect HAS the greenhouse effect increased with man-made greenhouse gas emissions? Canadian Ken Gregory asks and answers this question concluding…

The greenhouse effect as characterized by the normalized greenhouse factor has increased by only 0.19% from 1960 to 2008. The temperature change from 1960 attributable to AGW is less than 0.1 C. The extrapolated temperature change attributable to AGW at doubled CO2 concentration is 0.26 C. The data shows that the IPCC estimate of climate sensitivity at doubled CO2 concentration of 3.0 C is unrealistic.

US Supreme Court Impressed by Climate Sceptic

By

There was an important ruling last week in the USA. Would-be regulators of carbon dioxide lost an appeal in the Supreme Court.

They lost on technical grounds and in the process the Court cautioned, by way of a footnote in the judgement, that the science of climate change is hardly settled. Rather than citing some evidence, however, the Judge cited an article about the views of physics and sceptic Freeman Dyson, published in of all places, the New York Times Magazine and over two years ago.
