RHITU CHATTERJEE, HOST:
It's been a big week for climate change. President Biden is gathering with world leaders to talk about how to prevent its most catastrophic effects. And two of NPR's very own climate reporters are here to talk about how that might work. Lauren Sommer. Hi, Lauren.
LAUREN SOMMER, BYLINE: Hi.
REBECCA HERSHER, BYLINE: Hey there.
CHATTERJEE: Hello. Now, climate change wasn't really a priority in the last four years of the Trump administration, so what's the main goal of this White House climate summit?
HERSHER: This is basically America's way of saying, we're back. Climate is a priority again. And the U.S. wants the rest of the world to know that and to establish itself as a trustworthy partner for other countries, if it can.
