A chunk of ice seven times the size of Manhattan (as big as the Isle of Man if you prefer a more Anglo-centric news source) is hanging by a thread to the main, still-frozen body of the western Antarctic. Satellite images are showing the rapid disintegration of a 41km x 2.5km ice chunk, a part of the Wilkins Ice Shelf that has been there for hundreds, maybe 1,500 years. It is happening, the scientific consensus seems to be, because the seas are getting warmer. It’s that greenhouse thing.

So, what to do? Blame China? No, we need to take individual responsibility. Wait on the Garnaut report? No, too little too late. We must act now … of course! Let’s turn some lights off on Saturday. For an hour. That’ll fix it. Meanwhile, click on the image below to watch a video of what Earth Hour is up against.
