How Climate Change Shaped Hurricane Helene

Inside a special season 2 episode of Shift Key.

This is a special Hurricane Helene edition of Shift Key. Our regular programming will resume next week.

Nearly a week after Hurricane Helene made landfall, we are still coming to terms with the scale of its destruction. The storm killed at least 182 people, making it the deadliest cyclone to make landfall in the continental United States since Katrina. From Tampa Bay to Asheville, North Carolina, it caused the worst hurricane-related damage in a century.

Why was Hurricane Helene so bad? Why did it cause such horrible flooding in western North Carolina, South Carolina, Tennessee, and Georgia? And did climate change have anything to do with its destruction? To answer these questions, Rob and Jesse speak with Gabriel Vecchi, a Princeton geoscientist and one of the world’s top experts on hurricanes and climate change. Shift Key is hosted by Robinson Meyer is the founding executive editor of Heatmap, and Jesse Jenkins is a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:

Jesse Jenkins: One of the things that always strikes me, too, about these sorts of events is, you know, think about a dam or a levy, right? It is resilient to the point where it’s not, right? You can have one more inch of rainfall, and that’s what it takes to overtop the dam, or to flood the river banks, or these kinds of things.

And so we have designed so much of our civil infrastructure for these one-in-100-year events, what used to be one-in-100-year events, right? The design specs were for that infrastructure. And now those probability distributions are shifting, and the kinds of events that can overwhelm the design basis of this infrastructure are much more probable.

And you go, it’s not like this event was 20% more intense, and so the damage is 20% more. It’s a binary thing. You go from something that our systems were designed to handle to something that they weren’t, and they break in spectacularly damaging ways. And that’s what I see when I look at these kinds of events. This is not the first flooding that we’ve seen in Appalachia, right? We have built out a flood control system because this happens in river valleys in the mountains, where water gets concentrated.

But this kind of rainfall event was so catastrophic because it just overtopped all of that infrastructure. And like you said, there’s very little you can do, once the infrastructure is fixed, to prepare once you see a storm like this coming. We have to really rethink all of the civil infrastructure planning that we’re doing, and that’s just going to take so much time and so much investment.

Gabriel Vecchi: Well, but I think you’re getting there to the issue of the time scales, right? So the National Weather Service did a phenomenal job of predicting this. But this could only be predicted on time scales of days. In order to change our infrastructure, in order to find an infrastructure that is better, it’s a question of years and decades, and maybe longer. And I think there, we need to be forward-thinking. It is important to see this as a call to think about what can start doing now so that in 10 years, in 20 years, whoever is in this situation is in a better position to handle whatever’s there.

Part of it, of course, is going to be to improve our forecasts, to make them longer range, more reliable, capture the universe of possibilities that a weather event can throw our way. But part of it is going to be relatively … maybe sophisticated is not the right word — build actual things on the ground that are different, right? Put rebar in concrete places, rethink the way that we site our buildings, rethink the way that we, where we take water up from. And one way to look at that is as a challenge. Another way to look at that is an opportunity.

I went to, initially, to college, I wanted to be an engineer. I wanted to build bridges. That was my, coming out of high school, I want to be a part of building things. And as I was in college, I realized, number one, I couldn’t take any electives. I didn’t like that. But number two, we weren’t really building many things. And it was sort of like, I wanted to build things right now.

We’re in a position where we do need to build things. We should be building a lot of things. This is, in a way, a call to opportunity.

Meta Data Center Federal Pipeline Review Due Early Next Year

And more of the week’s top fights around development.

The United States.

1. Richland Parish, Louisiana – Gird your loins for the coming fight over the Meta Hyperion data center’s gas pipeline.

  • On Wednesday, the Federal Energy Regulatory Commission laid out plans for an environmental assessment of the Entergy pipeline for the Meta data center under the National Environmental Policy Act and stated it’ll be issued in early January 2027. Federal agencies have been ordered by the panel to complete any remaining decisions on authorizations by April.
  • The decision to do an environmental assessment under NEPA will be controversial. The Sierra Club filed comments to FERC stating they wanted an environmental impact statement instead that took into account the environmental impacts of the data center being fed by the pipeline, as well as a review of the project’s cumulative impacts, as the activist group said they’re explicitly linked to the data center’s operations. “The power stations and data center are not remote or speculative developments unrelated to the proposed action,” their comments read.
  • This is quite similar to what’s playing out with the Green Chile pipeline in New Mexico for Oracle and OpenAI’s Project Jupiter, which we recently explained could turn into litigation with high stakes for future gas pipelines linked to data centers. But to me, this conflict with Meta feels like it has more at stake for this individual project, as it’s playing out while construction on gas power plants for the data center has been underway for almost a year after earlier being blessed by state regulators.
  • I asked Sierra Club what could happen next. Eric Huber, one of their managing attorneys, told me on Thursday, “I heard the EA is expected in January, but we are in wait and see mode and will decide on further steps when it comes out.” Meta and Entergy did not respond to a request for comment.

2. Spartanburg County, South Carolina – I have one last data center race to tell you to watch on Tuesday: South Carolina’s 4th, on the northern rim of the state.

Is the Election Really About Data Centers?

Talking with Kevin Gundersen, the head of public affairs for Digital Realty.

This week’s conversation is with Kevin Gundersen, head of public affairs for data center developer Digital Realty. On Wednesday, Digital Realty released a fascinating poll as part of Infrastructure for America, a pro-data center organization that also includes Compass, Vantage Data Centers, and QTS. The poll pushed back on the idea that we’re currently in the middle of a “data center election”; instead, it found most voters are not expected to choose their national elected officials based on a politician’s stance on data centers.

I reached out to folks involved in the poll's release, and they put me in touch with Gundersen, whom I’ve met before and consider to be a straight shooter. He accepted my invitation to do a candid hot-seat chat about the findings, his thoughts on all the data center attack ads, and whether his industry’s actually recovering any ground with the American people.

Why Project Certainty Is the Thorniest Part of the Permitting Bill

Can a key section of BAAJA be saved from unintended consequences?

Any bipartisan bill to update the nation’s permitting laws was always going to be a compromise, with advantages for the oil and gas industry as well as clean energy. Proponents of the Senate’s latest attempt at permitting reform have painted it as a delicate balance, a hard-won opportunity, and an all-or-nothing deal.

What, then, to make of drafting errors, or unintended consequences?
