Part 3: Free Climate Change Lectures at Adelaide University
Podcasts and material related to the Climate Change Q & A seminars will be available at Professor Barry Brook's blog: bravenewclimate.com
Labels: Climate Change
I have been listening to these lectures and they are rather enjoyable.
Thank you for sharing your religion with us.
But as a scientist, the actual data presented in these lectures is rather interesting.
Pay attention to exactly what he is presenting as data and not to his words.
"Killing frosts in Australia" is evidence of Global warming?
Please compare computer model predictions with your own personal knowledge of your local climate.
They simply do not match.
Well, this year we had a record breaking heatwave, one of an increasing long series of heatwaves over the past few years. Autumn persisted past when we would expect winter and spring came early and feels hotter than usual for this time of year. Absolutely no frosts at morning winter soccer matches this year. So therefore I must conclude that global warming is occurring.
In my waking life as a biomedical researcher, I often come across this sort of error in reasoning. It usually goes along the lines of "My grandad smoked until he was 90, and he was healthy, so smoking doesn't cause cancer". We take local, anomalous conditions and extrapolate them to the whole world. To understand global warming, you need a global perspective, you cannot extrapolate your local experience to say there is no global warming, any more than I can extrapolate mine to say global warming is rampant.
See this recent paper for a more comprehensive view.
