Wear blue to go green this Saturday

They showed that 350 parts per million CO2 in the atmosphere is the safe limit for humanity.

The bad news is we’re already past that number – we’re at 390 parts per million, which is why the Arctic is melting, why drought is spreading across the planet, why humanity is facing perhaps its greatest challenge ever.

The good news: that number gives us a target to aim for.

If you’re free Saturday between 8am and 3pm, join in the activities for the International Day of Climate Action, beginning with the aerial photograph (using a boom lift, not a fuel guzzling helicopter or other aircraft) of hopefully hundreds of people forming the number 350 at Hong Lim Park.

More details of the day’s activities can be found here.
