Semi-Finalist Evaluation

Judges'' comments

Proposal: Aviation chemtrails: Aerosol influence on clouds (Cloud Albedo Effect) Contest: Geoengineering 2014 Thank you for your contest entry. We appreciate your willingness to share your ideas and also the time and effort you put into developing a proposal and submitting it to the contest. We have reviewed your proposal and found that it contained intriguing elements; however, have chosen not to advance it to the next round of competition. We encourage you to keep developing your idea. Transfer your proposal to a Workspace to re-open it, make edits, add collaborators, and even submit it into a future contest. You can do so by logging into your account, opening your proposal, selecting the Admin tab, and clicking "Move proposal". We welcome you to stay involved in the Climate CoLab community: support and comment on proposals that have been named Finalists, and vote during the public voting period to help select the contest’s Popular Choice Winner. Climate CoLab will be opening more contests throughout the year and you are welcome to submit your proposal to those contests as well. Keep up the great work. We hope that by working together, we all can create solutions that wouldn't otherwise be possible. Sincerely, Contest Fellows If there are additional comments from the Judges & Fellows, they will be included below.

I've heard a lot about inserting sulfur dioxide to increase albedo, and with a few reservations, it seems like one of the most feasible strategies being discussed to day. However, your proposal is an operational plan, rather than the research protocol/control strategy we called for in the proposal, so I'm afraid I can't justify advancing this proposal to the semifinals. I hope you'll check the contest again next year, to see if the contest is seeking substantive geoengineering plans.
