‘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.

Forging through the arctic with research tech and iPhones

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.»

Lemon8 and TikTok Could Be Banned. Here’s How the Apps Are Different

TikTok and Lemon8 are owned by the same parent company, but they offer different experiences.

TikTok faces another sale deadline Saturday, and unless a US buyer intervenes — or President Donald Trump extends the deadline again — the app could disappear for US users. If the ban goes into effect, TikTok wouldn’t be the only app to disappear: TikTok’s sister app, Lemon8, could be caught in the crossfire.

Lemon8 is owned by ByteDance, the same parent company that owns TikTok. It’s one of the top Lifestyle apps in Apple’s App Store, and it has more than 10 million downloads in the Google Play store.

«Lemon8 is a lifestyle community focused app powered by TikTok, where you can discover and share authentic content on a variety of topics such as beauty, fashion, travel, food, and more,» the app’s description reads in both stores.

Here’s what you need to know about Lemon8.

Note: I reached out to ByteDance for this story, and the company did not respond for comment.

What is Lemon8?

Lemon8 is a video- and photo-sharing platform that eschews the vertical-scrolling format of TikTok in favor of a Pinterest board-style format. But what Lemon8 and TikTok do have in common is that both have Following and For You tabs to show you posts from creators you follow and posts the app thinks you will like.

Lemon8’s content is split into six topic tabs, plus a seventh tab called All. The other tabs are Fashion, Beauty, Food, Wellness, Travel and Home. These tabs can be found across the top of your screen, and tapping into these tabs shows you recommended and suggested posts.

Posts can be swipeable photo collections like in Instagram, or TikTok-style videos. Some creators add text to their photos to label clothing or a product. Some will also include the price of the item in the text.

How is Lemon8 different from TikTok and other apps?

Lemon8 is different from other apps in terms of what is posted and how it’s presented.

Lemon8 has a lot of influencer ads and product recommendations. It’s difficult to tell what is and isn’t sponsored content, and this appears to be the norm across the app. TikTok also has sponsored content, but usually these are marked as such in the bottom-left corner.

There aren’t a lot of memes or jokes on Lemon8 compared to other apps, either. You can find memes on Lemon8, but various hashtags associated with «memes,» like «funnymemes» and «catmemes,» have fewer than 1 million views (as opposed to hundreds of millions on Instagram). This could be because Lemon8 is still catching on in the US, but my suspicion is Lemon8 isn’t meant for memes. It’s meant to be more of a guidebook to help you achieve a certain lifestyle or aesthetic.

There’s also a lot of writing in Lemon8. For example, post captions might include instructions for a recipe or a deeper breakdown of an outfit. TikTok captions can have useful information, but those captions are more about connecting posts to hashtags to get more views and don’t necessarily add new information to the TikTok post. Lemon8 uses captions in a similar way to Instagram posts, but Lemon8 captions have one key difference from Instagram: templates.

Lemon8 lets you use templates for your posts to help you quickly format and to give you an idea of what to caption your post. There are caption templates for fashion, shopping finds, beauty, food and travel.

Lemon8 reminds me of a mashup between the magazines Martha Stewart Living, Muscle & Fitness and Travel + Leisure. You can find some useful tips in Lemon8 to help you achieve a desired aesthetic or find some vacation inspiration, but it’s not clear what is and isn’t an ad.

What are people saying about Lemon8?

People’s reaction to Lemon8 is seemingly positive so far. One TikTok creator posted a video calling Lemon8 «Pinterest, but interactive.» Another said Lemon8 is a combination of Pinterest, Instagram and TikTok.

However, this positivity could be artificially inflated. ZDNet reports that many TikTok posts about Lemon8 have described the app with similar language, making some believe ByteDance paid these creators.

And some Lemon8 creators’ claims make this theory sound more viable. One Lemon8 creator told Insider that ByteDance paid them to post on the app. Two other Lemon8 creators showed Insider emails that outlined the app’s payment structure.

Who owns Lemon8?

ByteDance, the Chinese tech company that owns TikTok, also owns Lemon8. According to ZDNet, ByteDance is positioning Lemon8 to be an Instagram rival as more users stop using, or abandon, Meta’s app.

According to the Wall Street Journal, a leaked internal memo from Meta showed that Instagram engagement was declining. ByteDance executives could be hoping to capitalize on this by giving Instagram users an alternative app in the form of Lemon8. And while Lemon8 was released globally in 2020, the app’s recent growth might show ByteDance’s gamble is paying off.

Will Lemon8 be banned alongside TikTok?

Since Lemon8 is owned by ByteDance, which also owns TikTok, it’s possible that the app will be banned alongside TikTok on April 5.

The law requiring the sale of TikTok could be applied generally to other apps that are owned and operated by ByteDance and its subsidiaries. When TikTok shutdown operations in the US in January, Lemon8 was shutdown alongside the app. If TikTok shuts down again, Lemon8 likely will as well.

Should you download Lemon8?

Even with a shutdown looming, Lemon8 is free, so you can download and try the app now before the sale deadline. Just know the app’s posts resemble instructional guides more than memes to share, and many posts feel like advertisements.

What’s Lemon8’s privacy policy?

Most of Lemon8’s privacy policy seems standard for social media apps. It states Lemon8 collects personal and location information to provide you with a better app experience. Some collected information includes your IP address and browsing history. But part of the app’s privacy policy might raise eyebrows.

«The personal information we collect from you may be stored on a server located outside of the country where you live,» the policy reads. The company has servers around the world, according to the policy, so your information could be stored in any of them.

This is different from how Lemon8’s sister app TikTok stores some user’s data. The company stores US-based user data in Oracle servers. TikTok CEO Shou Chew said ByteDance employees in China can access this data, but with «robust cybersecurity controls and authorization approval» overseen by a US-based security team.

For more on the TikTok ban, here’s what to know about the Supreme Court’s decision, here’s what could happen next and here are other apps users are flocking to.

Skip Your iPhone’s Lockscreen: Here’s the Hidden Flashlight Trick You Need to Know

A couple of taps can really make a difference on your iPhone.

Not long ago, your iPhone’s lockscreen would only allow two app shortcuts that you couldn’t change: camera controls and a flashlight toggle. However, iOS 18.2 allows you to customize these shortcuts to almost anything you might want. This small but impactful change is one of many ways iOS 18 supercharges customization for iPhone and iPad users. But what if you still want an easy-to-access way to toggle your flashlight without unlocking your phone?

Apple introduced an accessibility feature in iOS 14 that, once enabled, allows you to perform actions by just tapping on the back of your phone. The feature is called Tap Back and it remains a sleeper feature that’s sneakily hidden away in your settings menu. Enabling Tap Back essentially allows you to create a button on the back of your iPhone to perform an action without needing to take up any space.

Once you have Tap Back enabled, it doesn’t take long to see how much of a game-changer it can be with its added convenience. Below, we’ll show you how to set it up so a couple of taps on the back of your iPhone will let you launch just about anything you want.

For more, check out what’s in the latest iOS 18.4 release.

How to set up Back Tap on iPhone

Whether you want to link Back Tap with your flashlight, camera or launch a different iPhone app, the path through your iPhone settings begins the same way.

On your compatible iPhone (iPhone 8 or later), launch the Settings application and go to Accessibility > Touch > Back Tap. Now you have the option to launch your action (in this case, your flashlight) with either two or three taps. Although two taps is obviously faster, I would suggest three taps because if you fidget with your phone, it’s easy to accidentally trigger the accessibility feature.

Once you choose a tap option, select the Flashlight option — or a different action if you prefer. You’ll see over 30 options to choose from, including system options like Siri or taking a screenshot, to accessibility-specific functions like opening a magnifier or turning on real-time live captions. You can also set up Back Tap to open the Control Center, go back home, mute your audio, turn the volume up and down and run any shortcuts you’ve downloaded or created.

You’ll know you’ve successfully selected your choice when a blue checkmark appears to the right of the action. You could actually set up two shortcuts this way — one that’s triggered by two taps and one that’s triggered by three taps to the iPhone’s back cover.

Once you exit the Settings application, you can try out the newly enabled Back Tap feature by tapping the back of your iPhone — in my case, to turn on the flashlight. To turn off the flashlight, you can tap on the back of your iPhone as well, but you can also just turn it off from your lock screen if that’s easier.

For more great iPhone tips, here’s how to keep your iPhone screen from dimming all the time and canceling all those subscriptions you don’t want or need.
