Welcome to Our Chaotic Neutral Spring

La Niña is over. El Niño is coming. In between, there’s Neutral — it’s just chaotic now.

For the past three years, our planet’s climate patterns have been ruled by a surprisingly long “triple-dip” La Niña. But a regime change is coming: La Niña is finally over.

One-third of the pattern of shifting winds and ocean temperatures along the Pacific that meteorologists call the El Niño-Southern Oscillation, or ENSO, La Niña is known for cooler temperatures and strong easterly winds. These come together to create extra-long, extra-destructive hurricane seasons, like the ones we’ve seen over the past few years, and parching the Southwest with drought.

Its counterpart, the El Niño, does the opposite, causing ocean temperatures to rise and winds to slow or even change direction. The northern United States and Canada become dryer than usual, and the Gulf Coast and South, at least in theory, see more rain and floods.

Usually, each climate pattern lasts somewhere between nine to 12 months, and we can sometimes go years without seeing either one.

While climate scientists think an El Niño is likely coming this summer, we are, for now, in the final third of ENSO, enjoying a period of relative calm that’s simply known as ENSO Neutral. This is when our planet’s climate patterns settle back to “normal,” with surface temperatures on the Pacific mostly hewing close to average and weaker easterly winds than during a La Niña.

But don’t be fooled: Calm on a global scale doesn’t necessarily mean calm on the ground.

Every year, the National Oceanic and Atmospheric Administration, or NOAA, publishes a report called the spring outlook, which is exactly what it sounds like: a late-winter prediction of what the season ahead will look like. This year’s report, published Thursday, makes the coming spring look like a mixed bag.

First, the good news: All the rain and snow slamming into California over the last few months has, at least temporarily, helped ease the La Niña-enhanced drought that’s gripped the West for years. According to the report, “winter precipitation, combined with recent storms, wiped out exceptional and extreme drought in California for the first time since 2020, and is expected to further improve drought conditions this spring.”

But easing the drought has come at a cost. Wind, floods, mudslides, and piles upon piles of snow have devastated communities and knocked out power for hundreds of thousands in California — and more rain is on the way. Once all the snow that’s fallen on mountains across the country starts to melt, NOAA predicts floods will come to other parts of the country as well. "Approximately 44% of the U.S. is at risk for flooding this spring,” said Ed Clark, director of NOAA’s National Water Center, in the spring outlook. Unlike the floods that hit California over the past few months, which were mostly due to torrential rain, spring floods are likely to come from rivers saturated with snowmelt overtopping their banks.

But snowmelt should bring some much-needed relief to parts of the Colorado River basin, which is in the midst of a drought that’s brought Lake Powell and Lake Mead to historic lows. Yet as droughts ease in some places, they look likely to spread or worsen in others. NOAA expects our “Neutral” spring to bring above-average temperatures and potential droughts to parts of New Mexico and Washington State that are currently drought-free.

For a period of relative calm, that sounds pretty chaotic. But an El Niño might be even worse — it tends to bring periods of warming, and some think the arrival of one this summer could be a preview of what the world would be like under 1.5 degrees Celsius of warming.

Enjoy our chaotic Neutral moment while it lasts.

If there was ever any question that Donald Trump would be the 2024 Republican nominee, there isn’t anymore. Since he vacated the White House in 2021, the former president has silenced numerous rivals within his party — most recently ending Nikki Haley’s campaign in a Super Tuesday near-sweep — as well as legal challenges to his ability to run for federal office, leaving him the last Republican candidate standing. And if current general election polls are any indication, Trump isn’t slowing down as he turns his attention to unseating President Joe Biden.

The Trump vs. Biden rematch will serve in part as a referendum on the latter’s climate agenda — namely, the Inflation Reduction Act, the landmark climate legislation enacted in 2022. In the years since the IRA’s passage, Republicans have become savvier in their attacks on climate change, honing their rhetoric and misinformation about EVs, the energy transition, and climate science more broadly. The Heritage Foundation even published an extensive playbook for how, exactly, Trump should dismantle most of the progress on the green transition.

AM Briefing: Cybertruck, Recalled

On sticky accelerators, Alaskan oil, and sinking cities

Tesla Just Recalled Nearly 4,000 Cybertrucks

Current conditions: Unseasonably heavy rainfall killed at least 130 people across Pakistan and Afghanistan • Temperatures will soar to 111 degrees Fahrenheit today in Mali • It will be cool and cloudy in NYC, where thousands of high school students are expected to leave class to join a climate strike.

THE TOP FIVE

1. Tesla recalls Cybertrucks over sticky accelerator pedals

Tesla is recalling 3,878 Cybertrucks due to potentially faulty accelerator pedals. According to the National Highway Traffic Safety Administration, “the accelerator pedal pad may dislodge and become trapped by the interior trim,” causing the vehicle to accelerate unintentionally. Or, as Rob Stumpf at Inside EVs put it, this issue “could potentially turn the stainless steel trapezoid into a 6,800-pound land missile.” The recall affects every single Cybertruck that has shipped so far,according toTechCrunch. Owners will be notified by mail, and Tesla will replace or repair the accelerator pedal at no charge. The news caps off a rough week for the embattled EV maker that started with mass layoffs.

Decarbonizing the global economy requires replacing stuff that emits carbon dioxide with stuff that doesn’t. At its heart, this challenge is financial: All these high-emitting assets ― coal plants, gas stoves, airplanes ― were at some point financed into existence by investors seeking returns. Climate policymakers’ greatest challenge is not just figuring out how to phase out existing, dangerous capital investments in fossil fuels, but also how to finance into existence new, climate-stabilizing clean assets.

This is all much easier said than done. Central banks’ high interest rates are strangling clean energy and adaptation infrastructure investments in the United States and abroad. Recent struggles to develop offshore wind and small modular nuclear reactors in the United States exemplify how deeply hesitant private developers are to commit to long-term capital expenditures. Investors view these projects as too risky, their expected profits too low to meet their minimum return thresholds. Absent policies to stabilize supply chains and other factors affecting the financing environment for clean energy, the United States ― to say nothing about the rest of the world ― won’t meet its climate goals.
