This is GPS, the Global Public Square. Welcome to all of you in the United States and around the world. I'm Farid Zakaria, coming to you live from New York.

Today on the program, Joe Biden goes abroad for only the second time as President, to the G20 in Rome, and to COP26 in Glasgow.

We meet with the eyes of history upon us.

Is America back atop the world stage? Or are we in a post-American world?

I will talk to the President's National Security Advisor, Jake Sullivan.

American leadership has to have a different character.

About that, plus progress on climate change, concerns over China's military build-up, and much more.

And, a TV personality whose views, view to the far right, is eyeing a run for President.

I'm not talking about Donald Trump. Brother Francis Eric Zemoul.

Bernard O'Reilly will tell us how this provocative pundit may upend French politics.

But first, here's my take. Believe it or not, there is some real good news on the climate front this week.

Approximately 100 countries announced an agreement to cut methane emissions 30% by 2030, closing a glaring gap in climate policy.

They also reached a broad agreement to end deforestation in the same time frame, including pledging funds to back it up.

Deforestation, by the way, produces about 10% of the world's carbon emissions.

The private sector has committed to align $130 trillion with the goal of net zero emissions in their investments by 2050

toward limiting global warming to 1.5 degrees Celsius.

Positive technology trends are also accelerating.

In the past 10 years, the cost of solar and wind power has declined by 89 and 70% respectively.

And over the past three decades, lithium-ion battery prices have gone down about 97%.

Thanks to clean energy and efficiency, it is now possible for countries to grow their economies without increasing carbon emissions.

Alas, it's not enough. We need emissions to actually fall and buy a lot, not simply stay constant, and we are not on track for that to happen.

Even if all countries follow through on the commitments in the Paris Accords, and most have not, that will reduce carbon emissions by just 7.5% by 2030.
