Think global, act local.

This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.

We have to get to the point where each individual, each corporation, each community chooses low carbon, because it makes fundamental sense. It should become a no-brainer.

We shouldn't have stupid cars that use liquid fossil fuels. Come on, how outmoded is that? We have to get to the point where this is no longer a part of our experience.

When you have a vision of where you need to go, it sounds utopian. But when you get to the tipping point, your understanding switches.

We're going to get to the point where we ask how the hell we put up with high carbon for so many years. You thank your lucky stars, because you are seeing this transformation in your lifetime. You are going to tell your children and your grandchildren you saw this whole thing in front of your eyes.

Connect with people, visibly and loudly showcase initiatives that reduce greenhouse gases emissions, nurture youth leaders, or spread the message by raising awareness through campaigns. I am convinced that your contributions will ensure that climate change solutions safely power our - and especially your - future.
