Now comes the threat of climate crisis - a threat that is real, rising, imminent, and universal. Once again, it is the 11th hour. The penalties for ignoring this challenge are immense and growing, and at some near point would be unsustainable and unrecoverable. For now we still have the power to choose our fate, and the remaining question is only this: Have we the will to act vigorously and in time, or will we remain imprisoned by a dangerous illusion?

There are many who would much prefer that the word 'climate' never be mentioned and that the issue be eliminated from our national conversation.

There is the natural tendency that all of us are vulnerable to, to deny unpleasant realities and to look for any excuse to push them away and resolve to think about them another day long in the future.

I was born a poor black child.

I feel passionate about solving the climate crisis.
