Hey, short wavers. Emily Kwong here with NPR climate reporter Rebecca Herscher. Hi. Who is bringing us this month's listener question for NatureQuest? Okay, Becky, what do you got?
All right. This month's question comes from a listener in Santa Cruz, California.
I love how we're automatically game show hosts right now. Welcoming onto the stage. Santa Cruz, it's on the coast, right? It's an area a little bit south of San Francisco.
Yeah, I've actually never been there, but I've heard it's very gorgeous. I've seen pictures. There are cliffs, there are beaches. This listener, though, his name is Peter Lansdale, is kind of worried about what's going to happen to that landscape in the future.
Hey Shore Wave, this is Peter from Santa Cruz, California. I am wondering what the projections are for sea level rise in the next couple decades. We've seen a lot of damage recently on our coast, and to some extent that's normal because we're built on sandstone and everything is always changing here, but it would certainly accelerate if the sea was any higher than it already is. So I'm wondering if there's consensus on how many feet we're looking at.
All right. What do you think, Becky? I love this question. I do. It's such a simple and important one. Yeah. Basically, is there a scientific consensus about how much sea levels will rise and how quickly it'll happen? And since we don't all live in beautiful Santa Cruz, we'll also answer a different question, which is, you know, is the amount of sea level rise that's happening different in California versus, say, Louisiana or Virginia? Yeah.
So for this month's Nature Quest, we are tackling sea level rise, how fast it's happening, what humans could do to slow it down, and how to find out what the future looks like where you live. You're listening to Shortwave, the science podcast from NPR.

It is NatureQuest Day. This is my favorite segment. It's our monthly segment that brings you a question from a shore waver who's noticing a change in the world around them. And we've brought on one of the best, Rebecca Herscher, climate reporter at NPR. Okay, Becky, let's start with the first bit of Peter's question about sea level rise. Is there scientific consensus about how high the water will get?
An excellent question and a fun one to answer because the answer is yes, definitely.
Well, I guess that's it then. That's the episode. Okay, you've been listening to Shortwave from NPR.
Can you imagine we just end the episode? Get out of here. Yeah, if only if we're that simple. So basically, the answer is yes. Scientists have a really good idea of how much sea levels will rise in the next three decades or so. And I'm going to give you some concrete numbers because just from listening to Peter, I kind of get the feeling that that is what he's yearning for.
Me too, yeah.
Okay, so let's start really big picture. Globally, the oceans are about nine inches higher today than they were in the 1880s. So that's the worldwide average for all the oceans everywhere. And sea level rise is accelerating. So by 2050, sea levels are projected to be about 15 inches higher than they were in the 1880s. Again, that's the global average, the whole planet. How sure are scientists about those numbers? They're really sure. So 2050 is actually pretty soon in scientific terms. And it takes time for the planet to react to the extra heat that humans have trapped in the atmosphere. So even if humans totally stopped burning oil and gas and coal today, there would be a lag while all that extra heat dissipated and the glaciers stopped melting.
And that lag would take decades.
