Yet another climate scientist joins the ranks of thousands of climate scientists working against all odds (the “consensus of scientists” —wink!) to debunk the theories of man-made global warming freak-out artists.
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.
In one of the more expensive ironies of history, the expenditure of more than $US50 billion ($60 billion) on research into global warming since 1990 has failed to demonstrate any human-caused climate trend, let alone a dangerous one.
Yet that expenditure will pale into insignificance compared with the squandering of money that is going to accompany the introduction of a carbon trading or taxation system.
