We have to know who we are and know what we believe.

I have to separate my personal concerns from my professional responsibilities.

It is manifestly in the interest of the United States to deal with the very real threat that climate change poses. And that's why President Obama has worked so hard to reduce our own emissions and to lead internationally in forging the Paris climate agreement.

I was conscious of the fact that it could be to my disadvantage to marry a white guy - that some folks would hold that against me.

I would rather be alone and a loud voice for action than be silent.

I think one of the real issues that we're faced with is how we consume news, how the media is perceived, how fake news is gaining a degree of currency without criticism that is dangerous, in my judgement.

It's in our interest to continue with the Paris Agreement and to deal with climate change as the real threat it actually is.
