Alex Honnold doesn't really do "vacations." While most people associate the world's most famous rock climber with the sun-drenched granite of Yosemite, his expedition to the frozen wilderness of Greenland for the Disney+ and National Geographic series Arctic Ascent with Alex Honnold was something else entirely. It wasn't just a climbing trip. It was a 30-day gauntlet.
He went there to climb Ingmikortilaq.
It’s a massive, 3,750-foot sea cliff. That is nearly 1,000 feet taller than El Capitan. But unlike the solid, reliable granite of the Freerider route, Ingmikortilaq is basically a crumbling pile of ancient gneiss and schist that wants to fall on your head. Honestly, watching him scale it feels less like a feat of athleticism and more like a high-stakes game of Jenga where the loser gets buried in the Arctic Ocean.
Why Greenland? It’s Not Just About the Rock
People kept asking why he’d leave the comforts of California for a place where the "summer" temperature hovers around freezing. The answer is climate change, but not in the preachy way you might expect. Honnold teamed up with glaciologist Dr. Heïdi Sevestre to collect data that is physically impossible to get with a drone or a satellite.
They needed to measure the depth and temperature of the Renland Ice Cap. To do that, they had to cross the Daugaard-Jensen Glacier.
Glaciers are alive. They groan. They crack.
The team wasn't just there for the summit push; they were acting as high-altitude lab assistants. Sevestre’s work focused on "real-time" melt rates. It turns out that the Greenland ice sheet is shedding ice at a rate that defies most older models. By climbing these remote faces, the team could access "virgin" ice and rock samples that haven't been contaminated by local human activity.

The Reality of Climbing Ingmikortilaq
If you think this was a repeat of Free Solo, you're wrong. Honnold used ropes. He had to.
The rock was terrible.
Joining him were world-class climbers Hazel Findlay and Mikey Schaefer. Even for them, the technicality wasn't the grade—it was the instability. In the show, you see massive chunks of the cliff face simply disintegrating under their touch. You can’t "free solo" something that moves when you grab it.
Breaking Down the Vertical Mile
The climb was split into sections. The lower half of the wall was damp and covered in lichen. Not fun. As they got higher, the wind became a structural enemy. Imagine hanging off a wall twice the height of the Empire State Building while Arctic gusts try to peel you off like a sticker.
They spent nights on portaledges. These are essentially hanging tents.
Sleep is a theory, not a reality, when you’re suspended over a freezing fjord. Honnold, ever the stoic, seemed less bothered by the heights and more focused on the logistics of the scientific sensors they were dragging up the wall. Most professional athletes would complain about the extra weight. He treated it like a puzzle.

The Scientific Stakes Underneath the Spectacle
Dr. Heïdi Sevestre isn't your average academic. She’s a field researcher who spends months in the most punishing environments on Earth. During Arctic Ascent with Alex Honnold, she helped the crew understand that the fjord they were sailing through shouldn't have been that clear of ice.
The "Arctic" part of the ascent is disappearing.
- The NASA Connection: The team used a "radar" system to measure ice thickness that contributed to NASA's Oceans Melting Greenland (OMG) project data pool.
- The Melt Factor: They witnessed firsthand the "moulin" formations—giant holes where meltwater pours from the surface of the ice sheet down to the bedrock, lubricating the glacier and making it slide faster into the sea.
- The Biodiversity Gap: They also looked for life in places it shouldn't be, finding extremophiles that survive in the cracks of the cliff.
It’s easy to get distracted by the sweeping cinematography. National Geographic knows how to make a mountain look like a god. But the underlying tension of the series is the realization that the landscape Honnold is climbing might look fundamentally different in just twenty years.
The Team Dynamics: Who Actually Gets Him to the Top?
Hazel Findlay is a legend in her own right. She’s known for "headpointing"—climbing dangerous routes with minimal protection. In many ways, she was the MVP of the expedition because her mental game matches Honnold’s, but she brings a different technical perspective.
Then there’s Mikey Schaefer. He’s the guy who has to climb the mountain and film it.
People forget that for every shot of Alex looking lonely on a ridge, there is a camera operator hanging from a rope nearby. The logistics of keeping batteries warm in sub-zero temperatures is a nightmare. They used solar arrays, but when the Arctic fog rolls in, you're basically out of luck.

Addressing the "Boredom" Critique
Some viewers complained that Honnold seemed "bored" during the trek.
He wasn't bored. He was calculated.
In high-stakes mountaineering, excitement is usually a sign that something is going wrong. If you’re screaming and hooting, you’re burning oxygen and losing focus. Honnold’s trademark "Alex" stare is just deep processing. He’s looking at the rock, calculating the friction coefficient of his rubber soles against wet gneiss, and wondering if the piton he just hammered in will hold if he slips.
The Legacy of the Expedition
So, was it a success?
Technically, yes. They reached the summit. They got the data. But the real "win" for the scientific community was the specific telemetry from the top of Ingmikortilaq.
We now have a clearer picture of how the heating of the North Atlantic is eating away at the base of these coastal cliffs. It's a feedback loop. Warmer water melts the ice, which changes the pressure on the rock, which leads to more rockfalls.
Actionable Insights for the Inspired
If you watched the show and felt the urge to go to Greenland, don't just book a flight. It’s an incredibly fragile ecosystem. Instead, consider these steps to engage with the reality of what the team found:
- Follow the Data: Look up the Arctic Monitoring and Assessment Programme (AMAP). They provide the actual peer-reviewed reports that Dr. Sevestre contributes to. It’s denser than a TV show, but it’s where the truth lives.
- Support Ground-Level Science: Organizations like the Climate Sentinels carry out non-motorized scientific expeditions. They do the hard work without the big Disney budgets.
- Audit Your Footprint: It sounds cliché, but the melt rates seen in Arctic Ascent with Alex Honnold are directly tied to global carbon outputs. Small shifts in how we consume energy actually matter when multiplied by billions.
- Understand Technical Climbing: If you want to understand why what they did was hard, go to a local climbing gym. Try to hold onto a "sloper" (a rounded hold). Now imagine that hold is made of frozen mud and is 3,000 feet in the air. You’ll get the picture.
The expedition proved that Alex Honnold is still the gold standard for vertical movement. But more importantly, it showed that even the most remote corners of our planet are no longer isolated from the choices we make in our living rooms. Greenland isn't just a backdrop for a TV show; it's the thermostat for the entire world. And right now, that thermostat is being turned up way too high.
