What are you doing on Saturday? Fancy a Samba through the city? Or a sailing trip on a tall ship around Sydney Harbour? Going to the beach to be part of a human sign? These are just a handful of the 4500+ events taking place this Saturday around the world to mark the 350.org day of action.

As I have written about previously 350 refers to the concentration, in parts per million of greenhouse gas emissions in our atmosphere, that scientists agree is needed to maintain a safe climate. The Day of Action is for people, organisations, anyone in the world to get involved and come up with their own creative way of promoting the 350.org campaign. Using the number 350 as inspiration, people are baking 350 cupcakes, making 350 origami figures and loads of other fun creative activities.

Word is some of the Dirty Kev crew will be at the Sydney Opera House taking part in this exciting project. Yours truly will be in Newtown getting down with the Newtown Climate Action Network. In Brisbane there is a huge event involving 350 frisbees and 350 drums that sounds really cool.

You can find these events and all the other exciting activities here.
