Earlier this year, I wrote a piece about the MIT Climate CoLab. Since that time, thousands of people from around the world have contributed potential solutions to climate change. The finalist proposals have now been critiqued, revised, and approved by international experts. So now you have a chance to say which ones you think should be implemented.

Voting is easy. Just login to the Climate CoLab website and select the “Vote for proposal” button on any proposal page. You get one vote per contest, and you can even change your vote as many times as you wish until midnight on Sept 30. (Check out the Climate CoLab’s Voting rules for more details.)

The proposal with the most votes in each contest will win the Popular Choice Award, and the author(s) will be invited to present in person or via video to key implementers at the MIT Crowds and Climate Conference on November 5, 6 & 7 at the MIT campus. Along with the prestige this entails, they will also get a chance to win the $10,000 grand prize.
