Climate CoLab at MIT

Over at MIT in the US, a project called Climate CoLab is investigating the power of online collaboration to suggest "what to do about climate change". The resulting website is somewhere between a moderated discussion forum and a voting tool for ideas to combat global warming:

I wonder what kind of people contribute to such projects - I'm assuming it will mostly be people who are very strongly engaged with climate change already, and as such it must be challenging to involve a representative group of people in discussion / voting activity.

Further information, and some working papers linked to the project are available here:

They do note that initially, some unrealistic ideas (such as reducing emissions by 99% in all countries by 2050%) tended to get the most votes (which may give some suggestions about the kind of people that are involved in voting). They have worked around this by getting expert climate scientists to review the suggestions and provide a shortlist for voting, however.
