It's true that climate change is an unprecedented problem so it's not surprising that it's so difficult to address.

Even those who specialize in the history of philosophy often ignore the political and cultural context, and the natural world in which their philosophers were philosophizing. This has consequences both trivial and important. If you systematically read the last fifty years of the major journals in our discipline you would be amazed at the amount of redundancy. Most of this is unacknowledged because most of us know so little about the history of our discipline and even the subfields in which we work.

If you're interested in doing something about climate change as we all should be, all of us who care about future people and creatures that will inhabit this world. Then buying a Prius is a good thing but an even better thing would be to be on the streets demanding urgent action from the United States' Congress.

In the last few centuries we've managed to reduce how much we kill each other, we've learned some basic lessons about public health, and life is relatively good for more people than ever before.

If we don't have historical consciousness we can't really understand problems in all their dimensions, and if we can't understand problems than we can't find solutions.

When it comes to climate change it's all the usual barriers: greed, mendacity, ignorance, short-sightedness and so on, manifest in the extreme power of corporations, the weakness of government, and the indifference of citizens.

Our traditional systems of decision-making are just not up to preventing changes in fundamental earth systems that are driven by a constant barrage of individually negligible emissions of an invisible, odorless gas, by billions of people all over the world.
