Things are gearing up big time for 350.org’s October 24th International Day of Climate Action. If you’ve been living in a cave and have somehow missed what 350.org is, it’s pretty simple.

From River of Action:

In 2007, NASA’s chief climatologist, Jim Hansen, released a study marking 350 parts per million of carbon dioxide in the atmosphere as the safe upper limit for humanity. Much more than that, and we risk dangerous temperature increases. Unfortunately, we’re at 390ppm and rising 2 ppm each year. Writer and activist Bill McKibben launched 350.org in response. The goal is to organize a grassroots campaign designed to educate the world about the runaway CO2 levels, and then motivate people to do something about it. Thousands of communities around the world will represent the number 350 as prominently as possible to send a message to world leaders bound for the UN Climate Change Conference this December in Copenhagen.

With actions planned for all over the world, it’s hard not to take part. Last night in Portland, River Action, along with help from Keen, Nau, Wend Magazine and Hopworks, hosted an October 24th pre-party. Basically an event to get people revved up on the need for climate change action and reminding us all not only to take part on the 24th, but in our everyday lives. [That and drink free beer BYOC style — Bring Your Own Cup]. On the 24th River of Action will be harnessing the power of paddlesports communities all around the world and having them form “350” on waterways. A creative idea that’s certainly getting some attention… can’t wait to get out on the river and take part!

Great event with an uber fabulous 350 cake. It doesn’t get much better than that.
