This Sunday, thousands of concerned citizens from around the world will be celebrating climate solutions and pressing governments for change. Organized by 350.org, 10//10/10 will be a day of global climate action, with Work Parties planned in New Zealand, Uganda, Bolivia and in cities across the United States, to name but a few. As 350.org founder Bill McKibben explained in a recent email, the 5249th event registered set the record for the greatest number of recorded protests in a single day in world history. The Nation wants your photos and stories from this momentous day!

Submit your images to The Nation‘s Flickr group and your shots may be included in a slide show on TheNation.com. Here’s how:

1. Log in to your Flickr account (if you don’t have a flickr account, you can sign up for free.) 2. Join The Nation‘s flickr group by clicking "Join this Group" on our Flickr group page. 3. Add your images of 10/10/10 events to The Nation‘s group pool, and tag your images with the tag NatMag10/10/10. Be sure to include a description and location for the event so that we can include it in our slide show.

Then check back next week to see whether your images are in The Nation‘s slide show, and view other events from around the world!

Finally, if you don’t have anything planned for 10/10/10, join a local event on Sunday, or organize your own.
