What I really like about Extinction Rebellion is that they organise the Rebellion with a really wide view: They take into consideration that humans are not perfect and that conflicts will arise. They take into consideration that we are not only logic creatures but emotional ones too. They take a multi-disciplinary approach: not only climate science but political, social and many other sciences too. And they try to include everyone. Because of these reasons, I believe they will change things.
Here is a video in which Dr. Gail Bradbrook explains how it all works in Extinction Rebellion:
