The Australian Parliament’s upper-house Senate has begun debating the Rudd Labor government’s proposed Carbon Pollution Reduction Scheme Bill 2009, also known as the emissions trading scheme. The legislation is based on the theory of anthropogenic global warming.
The vote of Family First Senator, Steve Fielding, is considered crucial. The Senator claims Australia’s Minister for Climate Change, Penny Wong, has not answered key questions from him concerning the science in particular: Is it the case that carbon dioxide increased by 5 percent since 1998 whilst global temperature cooled over the same period?
The Minister’s advisors have apparently argued with Senator Fielding about how to measure global temperatures, insisting that ocean as opposed to surface temperature, is a better measure.
Indeed heat is not the same as temperature. Two litres of boiling water contain twice as much heat as one litre of boiling water even though the water in both vessels is the same temperature. A larger container has more thermal mass which means it takes longer to heat and cool. So yes, measuring ocean temperature is a more accurate measure of heat accumulation.
NASA started deploying free floating Argo buoys in the world’s oceans in 2000 with the full complement of 3,000 in place by 2003, and data from these buoys indicate that even the oceans have started to cool.
This is very significant. While surface temperatures may vary from year to year, as long as atmospheric concentrations of carbon dioxide increase there will be a gradual accumulation of heat in the climate system eventually resulting in a climate crisis.
But so much for the legislation if the oceans are cooling; then the very hypothesis is falsified. Indeed given the nature of science, the fact that today’s theories are often disproven tomorrow, it is perhaps never a good idea to develop legislation on a scientific theory, however, popular.
