John Kerry: “the United States is always strongest when we speak with one strong voice on foreign policy.”

Coal is the dirtiest fuel in the world, and emissions that are not captured from coal are the worst cause of the warming of the ocean.

People think this is now, you cannot reverse it, it is irreversible.

What a shame for our country that that happened.

The message is, let's find a way to be able to make sure when we fly, we're not leaving emissions that we cannot capture.
