A new bit of scientific evidence that humans are causing global warming will be difficult for deniers to rebut. It seems the Earth's orbit cycle has the planet some 966,000km further away from the sun than it was in the time of the big J, when temperatures were 5-6° warmer than they are now.
We should therefore be going through a cooling cycle, according to boffins who have analysed core samples from an Arctic lake that show cycles going back 200,000 years. But the samples show things have been getting much warmer since 1950, bucking the cosmic cooling trend and pointing to human activity as the likely cause.
So much for Senator Steve Fielding's global warming graph beginning in 1998.
PS 27/10/09: Funnily enough, that climate change expert Cardinal George Pell was using the temperatures at the time of Jesus to argue the opposite on radio yesterday -- saying that it was warmer then so global warming isn't happening. He also brought up the 1998 fallacy which has been rebutted so many times, so publicly, that it beggars belief how much information these dogmatists can ignore. No doubt God has fed him his factoids direct.
