Hi Jen,

All things considered, I thought the debate went very well. The show of hands at the end indicated 50-50. I have had complimentary calls today. The following is a summary that Des Moore has sent around.

Climate Debate – Hawthorn Town Hall – 19 Nov

I attended last night a debate between Professor David Karoly, who is an adviser to Professor Garnaut and Victorian Premier John Brumby, and William Kininmonth at the Hawthorn Town Hall on “We should be concerned with human-caused climate change”.

I estimate that about 220 people attended and there was an “active” question time after the speakers completed their presentations. A show-of-hands vote taken at the conclusion suggested a slight majority in favour of WK.

I will not atttempt here to analyse the issues raised by either side other than to mention the heavy reliance on modelling by DK to “prove” his points. However, it is worth noting  the marked contrast in style of presentation, with DK adopting an aggressive approach (that provoked an initial adverse reaction from the audience) and WK adopting a calm relaxed one.

There is little doubt that DK’s approach lost him “votes” and, more importantly, left an impression that his expertise was not necessarily something on which much reliance should be placed. Indeed, it served to (again) confirm doubts about the basis of the science used by the IPCC, for which DK was a lead author…

My guess is that DK was a bit taken aback by the audience response, including a number of sensible questions…

The local Community TV Channel 31 filmed the event to show later and they said they would send a copy to me.

Friend or Foe? The Ocean’s Response to Climate Change
Carbon dioxide (CO2) in the atmosphere is the principle driver of future
climate change. Atmospheric CO2 concentrations have increased 30% beyond
pre-industrial levels through human combustion of fossil-fuel carbon and
will continue to increase rapidly into the future. The ocean covers 70% of
the earths surface, is the largest active reservoir of carbon on earth and
is the most important natural sink for reducing anthropogenic atmospheric
CO2. The ocean controls atmospheric CO2through both biological cycling
(phytoplankton production) and solubility cycling (thermodynamics). Here I
will discuss the latest scientific understanding governing climate change
impacts on the ocean : including implications for global circulation and
heat transport, oceanic CO2 uptake, pH acidification and changes in oceanic
biological production. I can then synthesize the likely future implications
in order to answer whether the oceans will be working for us or against us
in slowing climate change.

Ben McNeil is an Australian academic who is an expert in a range of areas
relating to climate change science, policy and energy.
Completing his PhD in 2001 he worked as a research fellow at Princeton
University, USA and returned to Australia in 2004, where he is now a senior
research fellow at the Climate Change Research Centre at the University of
New South Wales. In 2007, he was chosen as an expert reviewer for the United
Nations Inter-Governmental Panel on Climate Change 4th assessment report and
was invited to present his research to the Prime Minister and cabinet at
Parliament House in Canberra. He was also recently elected to represent
young scientists in the Federation of Australian Science and Technological
Societies.

His writing on climate change and energy policy has been widely published in
Australia¹s newspapers including the Sydney Morning Herald, The Age, The
Australian and The Canberra Times. He has also made numerous radio and
television appearances including ABC Radio National, CNN, BBC and Sky News
Australia.
