... this time about climate change. It's on the blog Hot Topic, where the author has written a rather sceptical review of an item in the Dominion-Post newspaper. The newspaper story included the statement that greenhouse gases don't cause global warming - rather surprising, given that in the absence of some level of greenhouse gases the world would be too cold for life as we know it! Both the post & its comments thread are worth reading.
