Dear friends,

For 20 years the world has managed to do very little about the greatest problem it's ever faced. In five days time, you can help change that--and if you step up you're going to have a lot of company!

It looks like the International Day of Climate Action this Saturday October 24th will be the single most widespread day of political action the planet has ever seen--we're closing in on 170 nations, and more than 4000 rallies and events.

There will be climate events from the bottom of the Great Barrier Reef to the summit of Mount Everest.  At each event -- at rallies and parties and deep-sea dives -- people will take a big photo that somehow depicts the number 350.  Our crew at 350.org will be taking these thousands of photos, projecting them on the giant screens in New York's Times Square, and delivering them directly to hundreds of world leaders and politicians in the coming weeks.

There's almost certainly an event happening near you--if you're not sure what, this link will let you find out quickly and easily:

Check out this fun update on what athletes are doing around the world for next Saturday from our friends at Outside Magazine. And if you haven't seen it already, make sure to visit our 350.org/athletes page to see all of the great athletes that have lent their support (and sweat) to this growing movement.

This Saturday, October 24th, will be action-packed. Normally, this would not be news for Outside readers, for whom most weekends are packed with biking, skiing, boating, etc. But this year, it's news. October 24th is the much-anticipated international day of action, designed to get everyone—really, everyone—talking about climate change and demanding action from world leaders to make real strides in mitigating its impact by signing a new, aggressive treaty during the upcoming United National Climate Change Conference in Copenhagen.

Hard to say whether this Saturday's actions will set off the chain re-action we imagined in the October issue  (well, OK, that scenario is a real stretch). But you're probably going to be out and about this weekend anyway, right? So if you believe climate change is happening, if you believe it is a real threat to humanity (not to mention your outdoor recreation opportunities), and if you can count to 350*, there's really no reason not to add your voice—and sweat—to the choir.

This past Sunday, the youth leaders of the 350 event in Quito, Ecuador gathered together in the Ciclopaseo, the weekly Sunday activity when the main street through Quito gets shut down to car traffic.  With unsustainable transportation all around us (highways on both sides and an airport right next door), we rode bikes, and painted colorful banners to symbolize our hope for a more sustainable future.  We handed out hundreds of stickers with info about the event the following week, an eco-festival and concert in Quito's historic Plaza San Francisco.  There, they will form a giant zero with candles in the evening, to be united with 3's and 5's in other parts of the world.
