‘Free Solo’ Star Alex Honnold Climbs Unexplored Arctic Mountains to Track Climate Change

His new National Geographic miniseries, Arctic Ascent, follows Honnold and his team tracking ice formation in Greenland’s frigid fjords.

Alex Honnold ascended to fame making one of the most daring no-rope climbs of a rock face in history, as documented in the award-winning film Free Solo. Then he turned to climbing for causes — the latest of which took him to the Arctic Circle, where he traveled with a team to measure the impact of climate change on some of the most remote parts of planet Earth.

Honnold’s expedition to check on Greenland’s ice, performed in 2022, was documented for a National Geographic three-episode miniseries that will arrive on Disney Plus on Feb. 5, titled Arctic Ascent.

Much like Honnold’s prior journey to track down undiscovered frogs up the sides of yet-to-be-climbed jungle mesas in South America, his venture in Greenland’s frigid fjords is filled with firsts. He and the team ascended a rock wall that hadn’t previously been climbed to reach an iced-over plateau that nobody had crossed on foot before, made a boat trip across uncharted waters, and finally ascended Ingmikortilaq, a 3,750-foot previously unclimbed mountain that’s nearly a thousand feet taller than Yosemite’s El Capitan cliff face, which Honnold summited in Free Solo.

“When we were sailing up the fjord in boats to go up to Ingmikortilaq, we did actually literally cross a point where there was no more information on the depth chart,” Honnold said. “We crossed a line and it was just blank after that. Nowadays, it’s relatively rare to go somewhere where you’re kind of off the edge of the map.”

As remote as Honnold’s trek was, what they were investigating has implications for the whole world. Emissions from burning fossil fuels are causing our climate to change, warming up the planet and leading to more extreme weather. As scientists expand their study of climate change’s impact, they’re also looking farther afield to understand how it can upset natural processes — and in Greenland, the melting of vast ice sheets could lead to a rise in global water levels, which could put coastal settlements around the world underwater.

The expedition took the team nearly 100 miles through subzero temperatures and even colder winds, which is difficult enough to endure in the open ice plain but extra torturous when climbing. As Honnold pointed out, you can’t climb with gloves as your fingers need to be free to grip holes and cracks in the sheer rock wall, so they must be exposed to the elements. And unlike Honnold’s previous trips to Antarctica, which had been cold but largely sunny, Greenland’s rain and snow meant many grim overcast days for his adventuring team.

Instead of finding frogs, the pro-environmental angle for this trip was to forge a path across ice fields and up mountain faces for Heïdi Sevestre, a glaciologist with the Arctic Monitoring and Assessment Program, who came to measure how climate change is affecting the formations of ice layers in arctic Greenland. Over the course of the journey, Sevestre took readings and collected samples in areas humans have never walked or climbed — a rare opportunity to collect data that could better our understanding of our warming world.

To Honnold, that’s a worthy cause for adventure. His post-Free Solo fame led to work that he funneled into a new foundation that has hooked up disadvantaged communities to solar power around the world. The Arctic Ascent expedition fed the same urge for Honnold to tend to the planet.

“I think a project like this is just a way to help talk about the environment to a mainstream audience, in talking about the importance of climate change, basically,” Honnold said.

Sevestre and Honnold make up a third of the six-person crew that went on the expedition, which also included Hazel Findlay and Mikey Schafer, two other climbers well-known for their skill in so-called “first ascents” up rock faces; as well as safety specialist adventurer Aldo Kane and Greenland guide Adam Kjeldsen. The challenging conditions and pioneering opportunities in adventure and science attracted them all to help crucial research at the edge of the world.

The three-episode miniseries documents the team’s arduous journey, which is peppered with interludes wherein Sevestre deploys scientific equipment to measure conditions and estimate their normalcy — or how much climate change has made them abnormal.

But the climbers sometimes need to court danger to get those instruments into the right position. One incident early in the series’ first episode has Honnold and others rappelling down a gaping hole carved by water rushing down to a glacier’s base, and dropping a piezometer into the flood to measure how much is flowing. Another data point to bring back to the scientific community from places it’s never accessed before.

Sevestre took a range of measurements over the course of the trip, including rock samples from the initial rock wall that could provide historical data to compare to modern climate progression. She took sonar measurements of the plateau to estimate how much water might flow into the world’s oceans if the ice sheets melt. And when they got past the ice field to the lake, she dropped a knee-high cylinder into the water — an actual aquatic probe for NASA (one of many in its Oceans Melting Greenland, or OMG, network of probes).

Honnold brought his iPhone.

While most of the miniseries is shot by National Geographic videographers with conventional cameras and drones for jaw-dropping ultrawide shots of gorgeous landscapes and sheer rock walls, it can be tough to get filmmakers into position in more extreme moments. So Honnold recorded a small portion of the footage himself in the fleeting triumph when he and his fellow climbers reached the top of an arctic wall that had never been climbed before. And he did it with an off-the-shelf iPhone.

“You’re almost required to do little video diaries [with phones] all the time because you just can’t capture it otherwise, those kinds of interactions where it’s just you and your partner at the anchor being like, ‘Here we are, we’re doing a thing, isn’t this exciting?'” said Honnold. He used either an iPhone 12 Mini or iPhone 13 Mini, he recalled.

Viewers won’t notice when the show seamlessly switches to his iPhone point-of-view, which is stunning proof that the smartphones in our pockets can produce documentary-quality footage, even at the edge of the world. Honnold kept the phone in an inner jacket pocket close to his warm chest for the most part so it wouldn’t die when exposed to Greenland’s subzero temperatures, but it still let him take part in contributing his own moments, from jokey chitchats with his team to euphoric cheers atop mountains, to the documentary.

Honnold has carried smartphones on climbs before, which he used to listen to music and take photos to send to family and friends. But phones have come a long way, and production companies now outfit him with the latest phones. His next trip, another National Geographic-recorded expedition to Alaska, has him using an iPhone 14 Pro Max so he can use its ProRes high-quality video format.

“The quality of phones now is good enough that you can put on a big screen,” Honnold said.

An expedition of science and adventure, the National Geographic way

The actual Arctic Ascent expedition happened in 2022, and Sevestre bundled her research into the trip to execute experiments for multiple universities. These myriad readings and measurements are, as Honnold described them, pieces of data that institutions around the world will use for different projects.

“Nothing we did is groundbreaking in and of itself, but that’s kind of the nature of science is that no individual piece of data determines any outcome. It’s always just part of this broader web of human knowledge,” Honnold said. “We’re hoping to fill in a gap in the map, for sure.”

That said, expeditions can be productive long after they’ve finished. The science expert from Honnold’s previous trip up the South American jungle mesas is still publishing research on the frogs discovered during the expedition, which occurred years ago. We won’t know the full impact of the Arctic Ascent expedition for some time, but there are other benefits to documenting such a tough adventure in some of the most wildly beautiful and unexplored parts of the world.

“I think showing the landscape is important, just showing people the wild beauty of Eastern Greenland. And I think that people can be inspired by nature in that way,” Honnold said. “But I think it’s nice to have an educational component, to have [Sevestre] along, to help people understand what’s at stake in Eastern Greenland.”

Kremlin Confirms Putin Transmitted Iran’s War Resolution Plan to Trump

The Kremlin says Putin relayed Iran’s proposal for ending the war to Trump, while Trump announced a Russian diesel supply deal that drew sharp criticism from Zelenskyy.

Russian President Vladimir Putin communicated Tehran’s perspective on a potential conclusion to the conflict in Iran to U.S. President Donald Trump, according to Russian state media reports on Saturday.

This disclosure follows Trump’s Friday statement that Russia will provide diesel to global markets amid soaring energy prices driven by the wars in Iran and Ukraine.

Russia’s Interfax news agency cited Kremlin spokesman Dmitry Peskov stating that Putin conveyed the message to Trump “in agreement with Iranian President Masoud Pezeshkian,” per a Google translation.

Additional Russian media accounts indicate Putin spoke with Trump by phone after meeting Pezeshkian on the margins of a summit in Turkmenistan.

Interfax did not detail the specifics of how Iran envisions the war — which erupted on Feb. 28 with U.S. and Israeli airstrikes on Iranian targets — reaching an end.

The White House did not immediately respond to Verum’s emailed request to confirm the reported conversation between Putin and Trump.

Russia supply deal

Trump announced Friday that Russia will deliver more than 4 million tons of diesel to the global market under an arrangement he said he agreed with Putin during a phone call.

Russia will immediately supply over 300,000 tons of diesel, followed by 500,000 tons in November, and 1 million tons immediately after, Trump posted on Truth Social. Moscow will then provide another 3 million tons of diesel contingent on the condition of Russia’s refineries, Trump added.

The Treasury Department temporarily waived sanctions on Russian diesel through April 2027 under a general license issued Friday.

Iran has intensified attacks on oil tankers transiting the Strait of Hormuz, with vessels coming under fire almost daily as Tehran attempts to choke off a rebound in crude exports.

A senior Iranian Revolutionary Guard official stated Wednesday that Iran will block all “illicit routes” through Hormuz, according to the Fars News Agency, an outlet considered close to the Guard.

The surge in tanker attacks coincides with crude oil exports from the Middle East rebounding in September to prewar levels, largely because the U.S. military escorted ships through Hormuz along Oman’s coast.

An interim agreement signed in June between the U.S. and Iran to pause hostilities to allow for negotiations quickly collapsed.

‘Gifts to Putin’

Ukrainian President Volodymyr Zelenskyy immediately denounced Trump’s diesel deal with Putin. Ukraine’s leader warned that easing sanctions without a commitment from Russia to de-escalate the war will only prolong it.

“Gifts to Putin will not bring peace or any benefit to the civilized world,” Zelenskyy said in a social media post. “Russia will ‘repay’ the diesel with further terror and perfidy. Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

Diesel prices have surged worldwide as Ukraine has pounded Russian refineries, forcing Moscow to ban diesel exports to global markets. Iran and its Houthi allies have also attacked refineries in the Middle East, further constraining fuel supplies.

Trump faces mounting political pressure to lower fuel prices ahead of the November midterm elections. Republicans confront competitive races in conservative strongholds like Iowa, where farmers feel the pinch of high diesel prices.

AI is Changing How Lawyers Work — and Putting the Billable Hour Under Pressure

AI is reshaping the legal industry by reducing the time needed for routine tasks, challenging the traditional billable hour model, and changing how lawyers learn and practice.

Artificial intelligence is now used by almost 90% of legal professionals in the U.K. and Ireland, and it’s putting one of the profession’s oldest conventions — the billable hour — under the microscope. That’s according to legal software company Clio’s U.K. & Ireland Legal Insights Report 2026.

It found that among firms using AI, almost 80% said they can handle more work without increasing resources, while over 70% said it cut costs by absorbing administrative work once done by support staff.

As a result, AI is challenging some of the assumptions on which the legal profession was built, forcing firms to reevaluate how their lawyers spend their time, how they charge for it and how new lawyers learn the ropes. You can’t charge 16 hours for something that takes 16 secondsNick Rowles-DaviesLexolent Some of the U.K.’s biggest firms are already putting this into practice.

A&O Shearman has worked with legal AI company Harvey to develop artificial intelligence agents for tasks, including reviewing loan agreements and analyzing regulatory filings, which it says can complete in minutes work that previously took several hours. Slaughter and May, meanwhile, has rolled out Harvey across all practice areas this year, including for regulatory research and document analysis.

Billable hour pressure The billable hour is central to the business model of many law firms, but when AI significantly reduces the time lawyers spend sifting through and drafting documents, the economics are no longer so straightforward. “You can’t charge 16 hours for something that takes 16 seconds,” Nick Rowles-Davies, founder and CEO of legal finance fund Lexolent, based in London and Dubai, told CNBC.

About one in five firms that have widely adopted AI report difficulty meeting billable-hour targets, according to Clio’s report. Globally, senior legal leaders expect the share of work charged by the hour to fall from 72% to 44% over the next two to three years, according to a Deloitte survey.

Routine work is the most exposed, Rowles-Davies said. “If you’ve got standard documents and you’re just putting in detail, then clearly that’s an automatic process.” But complex legal work still requires human judgment, he added, particularly when interpreting AI output and determining the right strategy for a client.

AI and workloads

Whether AI efficiencies ultimately make lawyers’ working lives better may depend on what firms do with the time they get back. Clio’s report found that 51% of legal professionals work evenings, but only 32% want to, while 22% work weekends compared with 11% who would choose to.

Joshua Lenon, Clio’s New York-based lawyer-in-residence, believes some lawyers are already seeing the benefits. “Lawyers [are] telling us that their day is getting better,” Lenon told CNBC, as AI becomes more commonplace.

“People are really looking at these tools and saying, ‘This is making work better.’”

Trump’s diesel agreement with Putin accused of contradicting Russia sanctions law

Ukraine President Volodymyr Zelenskyy said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

President Donald Trump’s Friday announcement that Russia will supply diesel fuel to the global market marked an apparent pivot from recent efforts to pressure Moscow to end the Ukraine war by targeting Russian energy exports.

Trump claimed the move, unveiled with less than a month left in an affordability-focused midterm election, would swiftly bring down record-high diesel prices.

But commentators and critics were quick to highlight contradictions between the new policy and prior efforts by the U.S. to clamp down on Russian oil sales.

Those efforts most recently included the enactment of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, empowering Trump to impose tariffs up to 100% on the top purchasers of Russian crude oil or gas, among other restrictions. Trump signed the bill into law just three weeks ago.

“Congress just passed a law giving Trump the power to impose new tariffs on major buyers of Russian oil & gas,” Scott Lincicome, vice president of the libertarian Cato Institute, said on X after Trump’s Friday announcement.

“Can America tariff America?” he quipped.

Sen. Richard Blumenthal, D-Conn., a member of the Senate Ukraine Caucus, accused Trump’s latest move of being “directly contrary to Congress’s intent in our bipartisan sanctions bill.”

Peter Harrell, visiting scholar at Georgetown University Law Center’s Institute of International Economic Law, in an X post said that the relaxation of Russian diesel restrictions “pretty much proves the point that the Graham Russia Bill was not going to force the Trump Administration to increase economic pressure on Moscow.”

Some of the criticism crossed party lines.

“Through the Lindsey O. Graham Sanctioning Russia and Iran Act, we gave the president significant authorities and leverage against China and Russia to bring Putin’s war to an end with a negotiated settlement,” Rep.

Michael McCaul, R-Texas, said in an X post. “Unfortunately, while I understand the desire to bring down diesel prices, I am concerned the lifting of sanctions on Russian oil will only fund the Kremlin’s war machine—emboldening more violence and destruction, as we have seen in recent days,” McCaul said.

The White House did not immediately respond to CNBC’s questions about the diesel agreement with Russia.

Less than a year earlier, the Trump administration slapped sanctions on multiple Russian oil companies in response to what it called “Russia’s lack of serious commitment to a peace process to end the war in Ukraine.”

Trump also had previously slammed NATO allies for continuing to buy Russian oil. In a September 2025 Truth Social post, he wrote, “the purchase of Russian Oil, by some, has been shocking! It greatly weakens your negotiating position, and bargaining power, over Russia.”

Later that month, Trump again harangued world leaders for doing business with Russia.

“They’re funding the war against themselves. Who the hell ever heard of that one?” he said in a speech at the United Nations General Assembly. “They can’t be doing what they’re doing. They’re buying oil and gas from Russia while they’re fighting Russia.”

Trump announced the diesel deal in a Truth Social post Friday afternoon after what he described as a “highly successful discussion” with Russian President Vladimir Putin.

Under the agreement, Russia will immediately supply more than 300,000 tons of diesel, then another 500,000 tons in November, followed by 1 million tons “immediately thereafter” and 3 million more depending on refinery conditions, Trump wrote.

The Treasury Department soon after said that Trump directed the Office of Foreign Assets Control to immediately issue a “temporary general license to allow the supply of Russian diesel to the global market.” OFAC specified that the sanctioned transactions will be authorized for about six months, until April 7.

Russia seemed to celebrate the move. “Russia-US cooperation on diesel and energy will benefit the world,” an X account associated with Putin’s economic envoy Kirill Dmitriev said in response to the announcement.

But Ukraine President Volodymyr Zelenskyy, whose military has started targeting Russian oil refineries, said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

“Any easing of sanctions against Russia without a clear and lasting de-escalation agreement with Russia is an obvious weakness,” Zelenskyy said. “Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

“We count on America’s fair support for our defense of life, for our defense of people in Ukraine – and on the United States having a correspondingly strong conversation with Russia,” he said.

“A strong one, not a weak one,” he added.

Trump thanked Putin later Friday afternoon for enabling “massive amounts of oil” to come to the U.S.

“We need oil for the world, and this is diesel, which is what we need, so we’re very happy to get it,” Trump told reporters before heading to Syracuse, New York.

The Trump administration has previously eased some Russian energy sanctions temporarily, though more narrowly than Friday’s announcement.

Earlier this year, in an attempt to stabilize markets after the start of the Iran war, the Trump administration issued limited, 30-day waivers allowing countries to buy sanctioned Russian oil that was already in transit.

But some interpreted the latest move as a more significant step.

“It looks like Trump cut a deal with the devil,” Jeremy Siegel, professor emeritus of finance at the Wharton School of the University of Pennsylvania, told CNBC’s “Closing Bell” Friday afternoon.

“It’s not a permanent solution at all. It’s sort of a short-term Band Aid,” Siegel said. “And cutting back on or eliminating sanctions on Russia for the invasion in Ukraine, I think, is a very unfortunate consequence.”
