High price for load of hot air by Bob Carter, June 18, 2007 12:00am
Professor Bob Carter is an environmental scientist at James Cook University who studies ancient climate change. Here’s some of what he has to say:
The salient facts are these. First, the accepted global average temperature statistics used by the Intergovernmental Panel on Climate Change show that no ground-based warming has occurred since 1998. Oddly, this eight-year-long temperature stasis has occurred despite an increase over the same period of 15 parts per million (or 4 per cent) in atmospheric CO2.
Second, lower atmosphere satellite-based temperature measurements, if corrected for non-greenhouse influences such as El Nino events and large volcanic eruptions, show little if any global warming since 1979, a period over which atmospheric CO2 has increased by 55 ppm (17 per cent).
Third, there are strong indications from solar studies that Earth’s current temperature stasis will be followed by climatic cooling over the next few decades.
It is past time for those who have deceived governments and misled the public regarding dangerous human-caused global warming to be called to account. Aided by hysterical posturing by green NGOs, their actions have led to the cornering of government on the issue and the likely implementation of futile emission policies that will impose direct extra costs on every household and enterprise in Australia to no identifiable benefit.
Not only do humans not dominate Earth’s current temperature trend but the likelihood is that further large sums of public money are shortly going to be committed to, theoretically, combat warming when cooling is the more likely short-term climatic eventuality.
