Want to help figure out what we should do about climate change? Know someone who does? How about someone who knows someone who does? You can win either way!

The MIT Climate CoLab is a site where people from all over the world can create proposals on what should be done about climate change. The CoLab is currently hosting contests in 18 different topics on everything from Enabling adaptation to Shifting cultures for a changing climate , and the creators of the best proposals will be invited to present their ideas at a conference at MIT this fall. The creators of the top ranked proposal will also share a Grand Prize of $10,000.

Go to Climate Colab

That’s not all! If you share the contest with your friends and colleagues through Facebook, Twitter or e-mail, and one of your friends (or friend of a friend, or friend of a friend of a friend, etc.) wins the Grand Prize, you’ll win a share of the $2,000 referral prize!

Here’s how it works: We’re giving $1,000 to the person who invites the winner of the Grand Prize of $10,000, $500 to whoever invited the inviter, $250 to whoever invited them, and so on...

It might play out like this: Alice enters her e-mail address below and we give her a unique invite link like http://climatecolab.impactree.org/1. Alice then e-mails her link to Bob, who also enters his e-mail address below so that we can give him a unique invite link like http://climatecolab.impactree.org/2, which he then posts to Facebook. Bob’s friend Carol sees the link, signs up to get her unique link, http://climatecolab.impactree.org/3, which she then posts to Twitter. Carol’s follower Dave then sees the link, signs up for the CoLab and creates (or helps to create) the best-ranked proposal, winning him theGrand Prize of $10,000. Once that happens we send Carol $1,000 for inviting Dave, Bob gets $500 for inviting Carol, and Alice gets $250 for inviting Bob.

Now you can use the link above (with a unique code for you) or the buttons to post on Facebook or Twitter, to tell your friends and family about the CoLab contest. Remember: If your sharing eventually leads to the winner of the Grand Prize of $10,000, even if you don’t know them or anyone they know, you’ll still win some of the $2,000, so share widely!

You can review the Consent Form any time.
