Climate action manages to be both obscure and highly visible

Five hundred climate activists gathered in a park field in Bonn, Germany on Saturday to stage a dramatic aerial image and send a message to the UN climate meeting that was taking place downtown.

Unfortunately, you need to be up on environmental news and/or willing to do some sleuthing to decode the message. 350 and Tck Tck Tck are both climate activist groups. The former takes its name from what is considered the safe upper limit of CO2 in the atmosphere, as measured in parts per million. The latter from the sound of a clock.

So basically, they’re telling the UN “We can save the planet if we agree to reduce CO2 emissions below 350 parts per million, but time is ticking.”

I hope the suits figured that out.
