The main point these people are making is that if we don't stop using fossil fuels pretty much _right now_, then it is too late. We already have the tech to do it, by and large. The questions are: * Do we have the political will to make these changes? * Will individuals be willing to change their lifestyles? No amount of undergraduate degrees in materials science or ecology will change the answers to those questions. But protest might - I for one find it compelling.
