Here’s a thought-provoking question from a book released today - David JC MacKay’s “Sustainable Energy – without the hot air”. It refers to a quote by Sir David A. King, who was chief scientific adviser to Blair and Brown’s government.

If climate change is “a greater threat than terrorism,” should governments criminalize “the glorification of travel” and pass laws against “advocating acts of consumption”?

Here’s another gem of a question posed in the book:

Climate modelling is difficult and is dogged by uncertainties. But uncertainty about exactly how the climate will respond to extra greenhouse gases is no justification for inaction. If you were riding a fast-moving motorcycle in fog near a cliff-edge, and you didn’t have a good map of the cliff, would the lack of a map justify not slowing the bike down?
