The TED Talk I watched was by a speaker named David Keith. He gave a speech about how we need to start thinking about the future of our planet. He went into depth about maybe we should not try to reduce emissions as a whole on a global scale, but instead have geoengineering in place to put up barriers and protect us from these emissions. I posted this talk to this blog because it gives a different look at the big picture of how we can protect our environment from the emissions that we have put into it. This talk was great because he gave methods of stopping global temperature rises in alternative ways that I had never thought of. When you watch this talk, you should expect to see an in depth analysis of the issue and three good ways on how we can put measures into reduces it.
