And that's why President Biden submitted the paperwork to immediately rejoin the Paris agreement as soon as he could hours after he was sworn in.

Today, as you've heard and as you know, it is absolutely official.

The United States is once again a party to the Paris agreement, and I'm proud and pleased with that fact.

But it also places on us a special responsibility.

We rejoin the international climate effort with humility and with ambition, humility, knowing that we lost four years during which America was absent from the table and humility and knowing that today no country and no continent is getting the job done, but also with ambition, knowing that Paris alone will not do what science tells us, we must do together.

So to be on track, to keep even a 66% probability of keeping global temperatures from rising more than 1.5 degrees.

To do that, we need to cut global emissions in half by 2030 so that means we need to phase out coal.

Five times faster than we have been.

We need to increase tree cover five times faster.

We need to ramp up renewable energy six times faster.

We need to transition to electric vehicles at a rate 22 times faster.

You get the drift.

Everything has to be done with greater sense of urgency with the determination that we have to win this fight.
