Late last year I participated in a webcast with MIT Professor Henry Jacoby. The subject was the cost of action on climate change – or more specifically the cost of cap-and-trade. Professor Jacoby leads the The MIT Joint Program on the Science and Policy of Global Change. From the perspective of the program, the question is no longer whether global warming is upon us . . . but how we can rise to its challenge. They are a world leader in this effort. Their many activities cohere around one strategy: science and policy have to work together. Shell is a sponsor of the program. Given that Massachusetts is well and truly back in the news today, it seems timely to post this video.
