I spent part of this afternoon asking people to send their own message to the politicians who will be at Copenhagen. Many were very willing - and a few took time to draw pictures and write throughtful contributions. But I found it sad that some said they thought there was no point - that things had gone too far and there was no way back.
They may be right - the target of limited global warming to 2 degrees only gives us a 50:50 chance of stopping the situation escalating out of control. But 50:50 is better in my book than certainty. We have to try.
Thanks to Friends of the Earth for running the "message in a bottle" event.
And I took a few minutes out to join a few hundred people at the Union Square Mall for a flash mob. We all fell asleep for 5 minutes - to the bemusement of many.
