Two new things on the climate front this week, both bad news. Typhoons used to be like drive-by shootings: one pass, one hit and then gone. Now they're starting to come back for a second hit.
And until now scientists only worried about the West Antarctic ice-shelf sliding into the sea (which would add three or four metres to sea-level). But they have just discovered that the main ice-sheet that covers Eastern Antarctica, 10 times bigger, is also in motion (potentially 52 metres of sea-level rise).
