ETS a big pain for little gain
By Professor Bob Carter, December 19, 2008
THE Intergovernmental Panel on Climate Change model of dangerous, human-caused climate change has failed. Independent science relevant to supposed human-caused global warming is clear, and can be summarised in four briefpoints.
First, global temperature warmed slightly in the late 20th century and has been cooling since 2002. Neither the warming nor the cooling were of unusual rate ormagnitude.
Second, humans have an effect on local climate but, despite the expenditure of more than $US50 billion ($70 billion) looking for it since 1990, no globally summed human effect has ever been measured. Therefore, any human signal must lie buried in the variability of the natural climate system.
Third, we live on a dynamic planet; change occurs in Earth’s geosphere, biosphere, atmosphere and oceans all the time and all over the world. No substantive evidence exists that modern rates of global environmental change (ice volume; sea level) lie outside historic natural bounds.
Last, cutting carbon dioxide emissions, be it in Australia or worldwide, will likely result in no measurable change in future climate, because extra increments of atmospheric CO2 cause diminishing warming for each unit of increase; at most, a few tenths of a degree of extra warming would result from a completion of doubling of CO2 since pre-industrial times.
These facts notwithstanding, the Rudd Government is poised to introduce a CO2 taxation bill on doubly spurious grounds. It presumes, first, that dangerous warming caused by human emissions is occurring, or will shortly occur. And, second, that cuts to emissions will prevent significant amounts of future warming.
There is, therefore, now a dramatic disjunction between scientific reality and the stranglehold that global warming alarmism has on planned Australian climate policy.
Today’s public views about climate change are based upon 20 years of promulgation of dangerous global warming by what has become a hugely powerful coalition of self-interested groups and agencies.
Beneficiaries of warming alarmism include individual scientists, managers of research centres, morally pretentious environmental non-government organisations, prestigious science academies and societies, bureaucrats from government greenhouse and climate agencies, big businesses poised for carbon trading (think Enron and Lehman Brothers), alternative energy providers, those in the media who remorselessly promulgate environmental alarm stories, and, last but not least, those uninformed politicians who seek political advantage from cynical exploitation of the public’s fear of global warming.
The Australian Government does not possess a national climate policy; instead, it has an imaginary global warming policy, based on sub-prime science, sub-prime economics and sub-prime politics.
