For the benefit of anyone who has spent the past decade or so on a different planet, the most frequently asked questions about climate change on this one are as follows. Is it getting warmer? Yes, surface temperatures have risen by 0.8°C from pre-industrial levels. Are humans causing it? Almost certainly. The gases produced by industrialisation and agriculture are known to have an insulating effect, and their concentration in the earth’s atmosphere has increased in line with rising temperatures, while natural causes of global warming have remained constant. Will it get warmer still? Very probably, though no one can accurately predict when or by how much.

It may tell us things we do not wish to know (about democracy, perhaps), but the future development of humanity may depend on what, if anything, it can teach us.
