Polar Bear hugs like this one were available for Chileans signing to protect the Arctic. Someone in a polar bear costume made it to most events, providing an iconic symbol.

It’s nearly impossible to sum up a year — especially in a field moving as quickly as technology and social change.

But among the 80 articles we published this year to analyse, learn, and share lessons in mobilisation and people powered campaigning, a few stood out.

Here are some of our most read and shared articles from 2012 — our first full year of operation, and a year when most everything went mobile, big data was in the news, and people-powered campaigns received big attention.

Check em out, share with colleagues, and please let us know what you want to hear about in 2013!

And be sure to take a look through photos, stories, tweets and more that capture people-powered actions to protect the planet in 2012. We tip our hat to colleagues at Greenpeace International for their work on this project.
