In the States we've had by far the largest demonstrations in the last few years. The largest civil disobedience actions about anything in US history in the last 30 years have all been centred around the climate.

There is a tendency at every important but difficult crossroad to pretend that it's not really there.

One of my favorite places is the Maldives, an all-Muslim nation in the Indian Ocean with a culture that stretches back 5,000 years. But since the highest point in the archipelago is a meter or two above sea level, even the next hundred are not guaranteed.
