I just wanted to draw your attention to a 10 week course on climate change literacy which began last week on the Coursera website and the University of British Columbia. It’s completely free and all you need is an internet connection. It looks at the science behind climate change and possible responses. From what i’ve seen so far its very interesting and you can sign up for it at any time in the 10 weeks. Why not check it out, especially if you find yourself having to have debates with people on this issue.
The website is – https://www.coursera.org/course/climateliteracy
A second course called “Global Warming: The science of Climate Change begins on 21st October and is available here – https://www.coursera.org/course/globalwarming
