Carbon dioxide from burning fossil fuels is changing the atmosphere and oceans.

We see it everywhere.

Mr. President, I'm here today for the 99th time to remind us...

Here for my 164th Time to Wake Up speech.

As I give my 200th Time to wake up speech, time to remind us that we are sleepwalking our

way toward a climate catastrophe and that it is time to wake up speech. Time to remind us that we are sleepwalking our way toward a climate catastrophe and that it is time to wake up.

Hi. Sorry to keep you waiting. Senator, it's nice to see you.

Senator, first of all, let me ask you, what spurred this quest, this desire to give a speech every week about climate change?

Well, you have to go back 202 Senate weeks and remember where we were.

We had passed cap and trade in the House.

The Senate, despite having a Democratic majority, had just walked away from that legislation.

We had done nothing.

The White House, under the President, had decided that they had had enough controversy, and

they walked away from the issue.

And you couldn't get them to put the words climate and change in the same paragraph

until the Georgetown speech that President Obama gave, there was a long, long drought.
