Global warming is real and human activity is the main cause. The consequences are mainly negative and headed toward catastrophic, unless we act. However, the good news is that we can meet this challenge. It is not too late, and we have everything we need to get started.

It's a blessing to have work that feels fulfilling.

Iraq's search for weapons of mass destruction has proven impossible to deter and we should assume that it will continue for as long as Saddam is in power.

When people flirt with despair about the future, they are less likely to take the actions necessary to safeguard it, focusing instead on the short-term.

The truth is that we're at a critical juncture in the history of our species and if we don't act soon, we could inhabit a world we don't recognize anymore.

Having cameras follow you is something that requires a little personal adjustment, but you actually do begin to forget they're there. It's impossible to maintain that awareness all the time, and when you're going through an emotional or absorbing experience, you really don't have any spare attention to think, "Got to remember that the camera is rolling."

We can believe in the future and work to achieve it and preserve it, or we can whirl blindly on, behaving as if one day there will be no children to inherit our legacy. The choice is ours; the earth is in balance.
