What makes this El Niño a “Super” or “Godzilla” event?

Unknown 0:00
This is Iraglass. On this American life, we tell stories about when things change. Like for this guy David, whose entire life took a sharp, unexpected, and very unpleasant turn. And it did take me a while to realize that it's basically because the monkey pressed the button. That's right. Because the monkey pressed the button. Surprising stories every week. Wherever you get your podcasts. You're listening to Shortwave. From NPR.
Nate Rott 0:29
By now you've probably heard or seen the headlines.
Unknown 0:32
Buckle up, there is some extreme weather coming our way global.
Nate Rott 0:36
Because we're in the midst of not just any old El Nino.
Emily Kopp 0:39
The World Meteorological Organization says that it's quote literally off the charts.
Unknown 0:45
Some scientists have nicknamed this a super or even Godzilla event.
Julia Cole 0:50
This year we're really seeing an El Nino for the record books.
Nate Rott 0:52
Look, as a Godzilla stand, I love any reference to the King of the Monsters, but even I'm like, what does that actually mean? That's the question we put to Julia Cole, the last person you just heard. She's a climate scientist and chair of the Department of Earth and Environmental Sciences at the University of Michigan.
Julia Cole 1:09
This El Nino is stronger at this point in time than any other El Nino that we have good data for.
Nate Rott 1:14
And she says it's still strengthening.
Julia Cole 1:16
Normally El Nino's reach their strongest point.

How strong is the current El Niño compared to historic records?

Julia Cole 1:19
Around November, December, January.
Nate Rott 1:21
So yeah. In Julia's opinion,
Julia Cole 1:23
we're virtually guaranteed to get a record breaking El Nino in the coming year.
Nate Rott 1:28
Now you might hear that and think, so what? El Nino happens every two to seven years. It's just weather, right? But this weather really packs a punch.
Julia Cole 1:38
Stronger El Niños lead to stronger impact, so we can expect more intense floods, droughts, temperature changes. We also are already seeing tropical storms coming in, striking Hawaii, drought in Indonesia, which is really extreme and leading to wildfires and terrible air quality across that region. Something like a quarter million acres or more have burned as a consequence of the drought in Indonesia.
Nate Rott 2:02
So whether you live in the US or abroad, there's a good chance you're going to feel this El Nino. You might already be, which is why we at Shortwave want to spend some time talking through the science of this natural climate phenomena, starting with a big question that scientists have had about El Nino for a long time. Are we humans making it worse?
Julia Cole 2:23
It's been very hard to determine the human fingerprint on El Nino and La Niña because there's a lot of what we call internal variability in them.
Nate Rott 2:31
Only now Julia thinks she's found an answer, buried in coral. So today on the show, how climate change is impacting El Nino and what that means for all of us living on land. I'm Nate Rott, and you're listening to Shortwave from NPR.
Ashley Lopez 2:56
This week on the NPR Politics Podcast, Republicans are on their heels and about to spend a lot of money on ads.
Unknown 3:03
Some of these uh ads are gonna be ugly and it's gonna be a pretty negative campaign. That's the nature of a midterm when you got a an environment like the one that the Republicans are facing.
Ashley Lopez 3:13
We look at the Republican money machine with less than 40 days until the midterms this week on the NPR politics podcast.
Josh Baker 3:20
Austin Tice is an American journalist who disappeared over a decade ago while reporting in Syria.

Are humans amplifying El Niño intensity and how do we know?

Josh Baker 3:27
And for years, we've been searching for him.
Julia Cole 3:30
This looks like a secret passage. I'm just
Josh Baker 3:32
pushing a door so you can get in. Listen to Where is Austin Tice from NPR's Embedded and BBC Radio 4 on the NPR app or wherever you get your podcasts.
Nate Rott 3:44
Okay, so before the break, I said something that I think needs a little more explanation, which is that El Niño, La Niña, this cycle, is a natural phenomenon, where in El Nino, the Pacific Ocean along the equator warms. That warmer water warms the atmosphere above it. Imagine holding your hand above a hot bath, right? Warm air rises.
Julia Cole 4:06
And at the same time, that rising air is a disturbance in the upper atmosphere that rearranges how the atmosphere circulates over the Pacific and outside the Pacific. So that's how anomalies or climate extremes get exported from the tropical Pacific into North America, South America, and even further beyond.
