The Good Route: Biking, Climbing, Paddling Down to 350

This Saturday, October 24th, will be action-packed.Normally, this would not be news for Outside readers, for whom most weekendsare packed with biking, skiing, boating, etc. But this year, it's news. October24th is the much-anticipated international day of action, designed to get everyone—really,everyone—talking about climate change and demanding action from world leadersto make real strides in mitigating its impact by signing a new, aggressivetreaty during the upcoming United National Climate Change Conference inCopenhagen.

Hard to say whether this Saturday's actions will set off thechain re-action we imagined in the October issue (well, OK, that scenario is a real stretch). But you're probably going to beout and about this weekend anyway, right? So if you believe climate change ishappening, if you believe it is a real threat to humanity (not to mention youroutdoor recreation opportunities), and if you can count to 350*, there's reallyno reason not to add your voice—and sweat—to the choir.

Here's a small sampling of the more than 4,000 events thatare planned, or already in motion, around the world (170 countries and counting):

A dozen Bay Area cyclists took off Monday on a 350-mileride down the California coast. They'll arrive in San Francisco on Saturday. Ifyou're in that 'hood, join them for the very last bit of their giro (details here).

*According to NASA scientist James Hansen, 350 parts permillion is the safe upper limit for atmospheric CO2. Many leading scientistsconcur with this estimation. Right now, we're at about 387 ppm. So we've got some serious back-pedaling to do.
