Climate change is our common crisis. People from all walks of life are reinventing the way they live and work to stop it. In partnership with public broadcasters in the US, we zero in on grassroots actions for a carbon neutral future. Coal has fueled our economy for generations. We've used it to heat our homes, drive our trains and power our grids. Hotter summers pushed many countries away from this burning rock. But some depend on coal for their energy, their industries and their livelihoods. And they're finding it hard to let go. We'll mine how they can mitigate the damage, ease their dependence, and move on to more sustainable sources.
