Cool heads needed on global warming The Age, Jan 19 2007

Main points:

• "On April 28, 1975, Newsweek published an article stating: 'There are ominous signs that the earth's weather patterns have begun to change dramatically …' ... article was entitled 'The Cooling World', and shows a graph emphasising how the average temperature had dropped 0.6 degrees Fahrenheit from 1940 to 1970. And so it seems, the media and science-supported climate cycle has fully turned in 30 years, but is still projecting disaster."
  • See The Global Cooling Myth (RC), 'They predicted global cooling in the 1970s' (CB)
• "The fact is the earth has cooled slightly since 1998, showing evidence that a "market peak" has been reached"
  • 'GW stopped in 1998' (CB)
• "this is despite rapid rises in fossil fuel consumption, and increasing carbon dioxide levels, much as happened from 1940 to 1970"
  • 'What about mid-century cooling?' (CB)
• "Geological coring data shows that natural rises in carbon dioxide levels follow temperature changes rather than cause them"
  • What does the lag of CO2 in ice cores tell us? (RC), 'CO2 lags, not leads' (CB)
• "The analysis of ice cores shows that past temperatures have been several degrees higher than now due to natural causes"
  • 'Current global warming is just part of a natural cycle' (CB), 'What's wrong with warm weather?' (CB)
• "11,500 years ago central Greenland temperatures increased by 7 degrees Celsius or more in a few decades, making the estimated 0.6-degree global increase over the past century seem trivial"
  • Revealed: Secrets of Abrupt Climate Shifts (RC)
• "It is also a fact that more than 90 per cent of the greenhouse gas effect is caused by water vapour"
  • Water Vapour: Feedback of forcing? (RC), 'Water vapor is almost all of the Greenhouse Effect' (CB)
• "the contribution from man-made carbon dioxide is estimated at 0.1 per cent"
  • Calculating the greenhouse effect (RC)
• "The focus on carbon dioxide as the major producer of climate change is thus highly contrived"
  • 'Climate scientists ignore water vapour' (CB)
• "The facts point to natural factors (as evidenced by work on sunspot activity) being behind climate change rather than human influence through carbon dioxide levels."
  • 'It's the sun, stupid' (CB), 'GW is natural' (CB)
• "The source of information is claimed by an exclusive few — government-funded scientists with an array of climate-change models and large computer systems. Government advice, which forms the basis for political decision-making, comes from these same restricted sources."
  • 'There is no consensus' (CB)
• "Given the limited publication of facts, with the notable exception of Lord Monckton's recent articles in Britain's Daily Telegraph, one might well ask if reasoned debate is being suppressed"
  • See Christopher Monckton for more details
• "one might well ask if reasoned debate is being suppressed, as occurs also, of course, at times of financial hysteria."
  • 'Consensus, or collusion?' (CB)
