At MIT’s Climate CoLab you can work with people from all over the world to develop ideas for what we can actually do about climate change. If you submit one of the winning ideas, you’ll be able to present it to the media, government officials, business executives, and scientists at an MIT conference on September 17-18, where a grand prize of $10,000 will be awarded. Even if you don’t have new ideas yourself, you can help improve other people’s ideas and support the ones you find most promising. Current contests address low-carbon energy, building efficiency, adaptation, geoengineering, and many other topics. Entries are due May 31.Can crowdsourcing save the planet?
