Is Ian McEwan a global warming denier in denial?

How would you like to go on a freebie to the Arctic Circle for a couple of weeks? Here’s the deal: all your travel expenses are taken care of; you stay on a beautiful old sailing ship, most likely in some remote, picturesque bay far off the tourist map; you’ll see killer whales and polar bears, possibly even the odd narwhal; you’ll get to zoom around the pristine wilderness on skidoos; your food is prepared by a top Italian chef; there’s lashings of booze (albeit rather heady North African plonk); almost all your travelling companions will be famous in some way: Vikram Seth, Rachel Whiteread, Ian McEwan, Marcus Brigstocke.

Oh all right — I lost you with Marcus Brigstocke. But up until that point it was sounding pretty tasty, wasn’t it? I know I’d be sorely tempted to go on a trip like that. I’ve been up there myself — a 300-mile round trip around Svalbard on skidoos in search of polar bears — and it really is one of the most awesome landscapes you’ll ever see.
