Last night I attended a climate change meeting at Glen Iris Uniting Church.
Thanks to the organizers and the Youth Decide group for running the evening. We had a good chance to discuss the science, to varying degrees of rationality.
A young member of the Youth Decide group, who had recently completed year 12 chemistry and is now studying first year Engineering, admitted that carbon dioxide is what makes plants grow.
Yet no-one wanted to discuss if increased levels of atmospheric carbon dioxide would make plants grow better!
Similarly, no-one knew that global warming stopped around 2001. In fact, many people fiercely disagreed. Here's the data:
UAH = University of Alabama, Huntsville satellite data
Note the downward trend (blue line).
So much for informed and objective debate.
