All over Queensland on Friday 12th August 2005, towns have experienced the lowest winter maximum temperatures on record. Rockhampton had the lowest temp since 1899. This is an equally valid indication of a pending ice age as a hot summer is of global warming.

We will only know for sure in 5,000 to 10,000 years. And the most probable consequence of waiting will be an extended interglacial warm period in which man will continue to thrive. The worst case scenario is that we put our entire world economy into free fall to restrict CO2 and then get hit with a 10 degree temperature drop that we are unable to cope with. Ten to fifteen millenia is the extent of the recorded variance between temperature changes and CO2 changes.

Do I need to spell that out again? Levels of CO2 have been demonstrated to act independently of temperature for up to 15,000 years. So anyone who seeks to extrapolate from a data set as short as a century is doing so for reasons other than science.
