I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.

I think that more diversity is a good thing, and fresh points of view articulated by people who are committed to excellence in journalism is a beneficial change in the American media landscape.

In the end, we must restore a balance within ourselves between who we are and what we are doing. Each of us must take a greater personal responsibility for this deteriorating global environment; each of us must take a hard look at the habits of mind and action that reflect - and have led to - this grave crisis.

The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.

My plan to put Social Security in an ironclad lockbox has gotten a lot of attention recently, and I'm glad about that. But I'm afraid that it's overshadowing some vitally important proposals. For instance, I'll put Medicaid in a walk-in closet. I'll put the Community Reinvestment Act in a secured gym locker. I'll put NASA funding in a hermetically sealed Ziploc bag.

The struggle to save the global environment is in one way much more difficult than the struggle to vanquish Hitler, for this time the war is with ourselves. We are the enemy, just as we have only ourselves as allies.

It should be lifted above partisanship because it's a question of survival. It's a moral issue.
