Troll, I thought the proposal was to make about 90 per cent of the north slope available for exploration? Hard to miss the calving grounds I would have thought.

America is churning out a hundred times more carbon dioxide per person than most other countries, and I suppose will going on doing so until the Alaskan permafrost melts. (It's nearly there now - just rack that temperature up another degree or so.) That will destabilise the whole North American continent, and maybe there will be a rethink at last.

Good piece, Kat - one or yours, I assume?
