What will Earth look like if all its land ice melts? Here's your answer.

Climate change isn't pretty.

A map of the United States post land-ice melt.

Land ice: We got a lot of it. Considering the two largest ice sheets on earth — the one on Antarctica and the one on Greenland — extend more than 6 million square miles combined ... yeah, we're talkin' a lot of ice. But what if it was all just ... gone? Not like gone gone, but melted?

If all of earth's land ice melted, it would be nothing short of disastrous. And that's putting it lightly. This video by Business Insider Science (seen below) depicts exactly what our coastlines would look like if all the land ice melted. And spoiler alert: It isn't great. Lots of European cities like, Brussels and Venice, would be basically underwater.

In Africa and the Middle East? Dakar, Accra, Jeddah — gone.

Millions of people in Asia, in cities like Mumbai, Beijing, and Tokyo, would be uprooted and have to move inland.

South America would say goodbye to cities like Rio de Janeiro and Buenos Aires.

And in the U.S., we'd watch places like Houston, San Francisco, and New York City — not to mention the entire state of Florida — slowly disappear into the sea.

Business Insider based these visuals off National Geographic's estimation that sea levels will rise 216 feet (!) if all of earth's land ice melted into our oceans.

There's even a tool where you can take a detailed look at how your community could be affected by rising seas, for better or worse.

Although ... looking at these maps, it's hard to imagine "for better" is a likely outcome for many of us.

Much of America's most populated regions would be severely affected by rising sea levels, as you'll notice exploring the map, created by Alex Tingle using data provided by NASA.

Take, for instance, the West Coast. (Goodbye, San Fran!)

Or the East Coast. (See ya, Philly!)

And the Gulf Coast. (RIP, Bourbon Street!)

I bring up the topic not just for funsies, of course, but because the maps above are real possibilities.

How? Climate change.

As we continue to burn fossil fuels for energy and emit carbon into our atmosphere, the planet gets warmer and warmer. And that, ladies and gentlemen, means melted ice.

A study published this past September by researchers in the U.S., U.K., and Germany found that if we don't change our ways, there's definitely enough fossil fuel resources available for us to completely melt the Antarctic ice sheet.

Basically, the self-inflicted disaster you see above is certainly within the realm of possibility.

"This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it and will continue to do so for tens of thousands of years to come," said lead author of the study Ricarda Winkelmann, of the Potsdam Institute for Climate Impact Research.

If we want to stop this from happening," she says, "we need to keep coal, gas, and oil in the ground."

The good news? Most of our coastlines are still intact! And they can stay that way, too — if we act now.

World leaders are finallystarting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

Nat Geo's 'Blink' tracks a family finding beauty while facing blindness as they travel the globe

“Let's go all in and fill their visual memory with as much beauty as we can."

Mia, Leo, Colin, and Laurent Pelletier pose on top of their camper van in front of adouble rainbow while in Mongolia.

True

“Blink,” a new film by National Geographic Documentary Films shows how a family with four children, three of whom are going blind, embraces life in the face of an uncertain future. It’s a testament to the resilience of the Lemay-Pelletier family but also a reminder for all of us to seize the day because all our futures are uncertain.

Edith Lemay and Sébastien Pelletier are the parents of Mia, a 13-year-old girl, and three boys: Léo, 11, Colin, 9, and Laurent, 7. Over the last six years, they’ve learned that Mia and the two youngest boys have retinitis pigmentosa, a rare genetic disease in which the cells of the retina slowly die. As the disease progresses, the person develops “tunnel vision” that shrinks until very little vision remains.

The diagnosis devastated the parents. "The hardest part with the diagnosis was inaction. There's nothing they can do about it. There's no treatment,” Edith says in the film.

However, even though the parents couldn’t affect the progress of the disease, they could give their children’s senses an epic experience that would benefit them for a lifetime.

“We don’t know how fast it’s going to go, but we expect them to be completely blind by mid-life,” said the parents. Mia’s impairment advisor suggested they fill her visual memory with pictures from books. “I thought, I’m not going to show her an elephant in a book; I’m going to take her to see a real elephant,” Edith explains in the film. “And I’m going to fill her visual memory with the best, most beautiful images I can.”

This realization led to an inspiring year-long journey across 24 countries, during which every family member experienced something on their bucket list. Mia swam with dolphins, Edith rode a hot-air balloon in Cappadocia, and Léo saw elephants on safari.

Colin realized his dream of sleeping on a moving train while Sébastien saw the historic site of Angkor Wat.

“We were focusing on sights,” explains Pelletier. “We were also focusing a lot on fauna and flora. We’ve seen incredible animals in Africa but also elsewhere. So we were really trying to make them see things that they wouldn’t have seen at home and have the most incredible experiences.”

Cameras followed the family for 76 days as they traveled to far-flung locales, including Namibia, Mongolia, Egypt, Laos, Nepal and Turkey. Along the way, the family made friends with local people and wildlife. In a heartbreaking scene, the boys wept as the family had to leave behind a dog named Bella he befriended in the mountains of Nepal.

But the film isn't just about the wonders of nature and family camaraderie. The family's trip becomes a “nightmare” when they are trapped in a cable car suspended hundreds of feet above the Ecuadorian forest for over 10 hours.

As expected, NatGeo’s cinematographers beautifully capture the family's journey, and in the case of “Blink,” this majestic vision is of even greater importance. In some of the film's quietest moments, we see the children taking in the world's wonders, from the vast White Desert in Egypt to a fearless butterfly in Nepal, with the full knowledge that their sight will fail one day.

Along the way, the family took as many pictures as possible to reinforce the memories they made on their adventure. “Maybe they’ll be able to look at the photographs and the pictures and they will bring back those stories, those memories, of the family together,” Edith says.

But the film is about more than travel adventures and the pain of grief; ultimately, it’s about family.

“By balancing [the parents’ grief] with a more innocent and joyous tale of childlike wonder and discovery, we felt we could go beyond a mere catalog of locations and capture something universal,” the directors Edmund Stenson and Daniel Roher, said in a statement. “Keeping our camera at kid-height and intimately close to the family, we aimed to immerse the audience in the observational realities of their daily life, as well as the subtle relationships between each of them. This is a film built on looks, gestures and tiny details—the very fabric of our relationships with one another.”

Ultimately, “Blink” is a great film to see with your loved ones because it’s a beautiful reminder to appreciate the wonders of our world, the gift of our senses and the beauty of family.

The film will open in over 150 theaters in the U.S. and Canada beginning Oct. 4 and will debut on National Geographic Channel and stream on Disney+ and Hulu later this year. Visit the “Blink” website for more information.

Chris Hemsworth's 'Limitless' series is a surprising celebration of female power

No fanfare or feminist pronouncements—just impressive woman after impressive woman being highlighted.

"Chris Hemsworth" by Gage Skidmore

Chris Hemsworth highlighted women who mastered the challenges he undertook in "Limitless."


Judging by his physique, Chris Hemsworth already appears to be a person who pushes himself to the limit. The guy convincingly plays Thor, the Norse god of thunder, for the love.

But even Hemsworth, with his bulging biceps and sleek six-pack, is bound by the laws of human nature, which include pesky limitations like fear and aging. Now that he's in his 40s, the Australian actor, husband and father of three wants to maximize his time on Earth. So in a six-part series on Disney+, he pushed himself to the brink in six different challenges to "discover how to live better for longer."

The titles of each episode—"Stress Proof," "Shock," "Fasting," "Strength," "Memory" and "Acceptance"—offer a glimpse of what kinds of challenges he undertook in his quest for optimal existence.

The series trailer shows some of what Hemsworth endured in these challenges, from doing a polar swim in the Arctic to walking a plank on top of a high rise to climbing a rope to a cable car dangling over a deep ravine.

What the series descriptions and trailer don't show is how many of the real-life examples of people who have mastered what he's trying to do are women.

I watched the series expecting that it would be well done and interesting, as most National Geographic specials are, but I kind of figured it would be a big testosterone fest. And it easily could have been created that way.

Instead, I was pleasantly surprised to find that the people Hemsworth met with to learn about how to prepare himself for each challenge were largely women who had already mastered what he was attempting. And the best part was, it was never pointed out directly. There was no big "female power" pronouncement, no indication that women were going to serve as his mentors for much of the series. But the featuring of women was noticeable and notable.

For instance, in the first episode, "Stress Proof," Hemsworth takes on the challenge of walking across a crane jutting out from the top of a high-rise building. Despite his daring feats on screen, Hemsworth has a fear of heights, so this challenge was particularly stressful.

To explore how to manage the stress of the crane walk, Hemsworth shared the impressive abilities of Faith Dickey, a mountain climber and highlining champion who walks across slacklines hung between cliffs. She shared how she learned to make stress her friend and channel it, as well as how she utilizes self-talk to make it across a narrow strip of fabric suspended hundreds of feet above the ground.

She even once did it in heels:

Following the Dickey example, Hemsworth met with a group of firefighters at a training facility in New South Wales to learn how to control his breath and heart rate under duress. He was teamed up with 16-year veteran firefighter Tara Lal to enter a burning building in full gear and attempt to "rescue" dummies from the inferno. Firefighting is a highly male-dominated career field, yet they chose a woman to be Hemsworth's mentor. Love it.

In addition to the specific skill mentors, the psychologist who helped Hemsworth through his preparation for the stress walk was also a woman, Dr. Modupe Akinola.

Each episode featured women who shared their wisdom and experience with Hemsworth, from all around the world. A Finnish woman who cuts holes in the ice and swims under it. A British American freediver who can hold her breath underwater for six minutes. The Indigenous women and girls who run through the rocky mountainsides of Sierra Tarahumara, Mexico. The 85-year-old weight-training African American woman who could inspire anyone to exercise. And the list goes on and on.

The diversity of people of all ages and ethnicities highlighted in the series, as well as the high proportion of awesome women, creates a far more well-rounded exploration of better and longer living than the "Chris Hemsworth does these six hard things, look at him go" entertainment one might expect based on the trailer. The understated representation is well done and very much appreciated.

10 of our absolute favorite photos from National Geographic’s Pictures of the Year 2022 issue

These are the best photos from more than 2.2 million taken for Nat Geo this year.

via National Geographic

National Geographic's Pictures of the Year 2022.

The editors at National Geographic had the impossible task of choosing the best photos taken for the magazine in 2022 for its Pictures of the Year issue. Why? Because this year, 132 photographers were sent on assignment in 60 countries and 2,238,899 images were filed.

But the editors were able to pare them down to 36 images that offer breathtaking glimpses of our shared human journey and remind us of the incredible planet we all share.

“The photos selected for ‘Pictures of the Year’ stop us in our tracks and make us pay attention to stories that need to be told,” Whitney Johnson Latorre, VP of visuals and immersive experiences for National Geographic Media, said in a statement. “Each image reveals a portrait of life in motion, encouraging us all to see the world around us in new and unprecedented ways; that is the power of visual storytelling.”

“I love that Nat Geo’s ‘Pictures of the Year 2022’ isn’t merely capturing the news highlights of the year; we’re showcasing the powerful stories of the year that our photographers around the globe have had their lens on,” noted National Geographic Editor-in-Chief Nathan Lump. “As a result, the collection captures novelty and surprise in a way that I believe expresses the best of what we do at Nat Geo.”

Here are 10 of Upworthy’s favorite images from National Geographic’s Pictures of the Year 2022.

A SpaceX Falcon 9 rocket, launched from Cape Canaveral in the early hours of June 19, streaks above a stand of bald cypress trees. This was the second time in less than a year that a SpaceX rocket appeared in photographer Mac Stone’s frame while he was shooting at night in a remote swamp. Stone says that the increased frequency of launches without fanfare “suggests that we have crossed over into a new era where cosmic missions are simply business as usual.”

Wild Asian elephants mingle with cattle at a garbage dump near Minneriya, in central Sri Lanka. The island nation is home to some 6,000 pachyderms living in close contact with people. Having lost their lowland forest home, elephants now seek out human-affected habitats, including croplands, and are master generalists, capable of eating at least 100 different plants. That doesn’t mean that Sri Lankan elephants are thriving; they instead may be coping. Researchers are tracking their levels of cortisol, a stress hormone, that could be detrimental to the elephants’ health

Visitors ascend the spiraling 150-foot-high boardwalk in the yellowing autumn at Denmark’s Camp Adventure to gain a new perspective on the forest southwest of Copenhagen—and, perhaps, on life itself. “Forest bathing,” among the woods’ most powerful and least tangible benefits, has been shown to reduce stress and improve mental and physical well-being.

To create this image of Bears Ears National Monument, Stephen Wilkes took 2,092 photos over 36 hours, combining 44 of them to show a sunrise, a full moon and a rare alignment of four planets. “Beyond the sense of awe and beauty,” he says, “there’s a palpable sense of history with every step you take.” This spectacular landscape in southeastern Utah exemplifies the risk to some of the country’s unique, irreplaceable places. One president preserved it at the urging of Native Americans who hold it sacred; another tried to open it to drilling and mining. The national monument is rich in archaeological sites, including the Citadel, an ancient cliff dwelling now popular with hikers.

Photographed at night with an infrared camera, a spotted hyena that scientists nicknamed Palazzo submissively grins and lays her ears back as Moulin Rouge, the clan’s dominant female at the time, towers over her. Palazzo’s cub peers out from between them. Unlike most social mammals, females rule among spotted hyenas, maintaining their hierarchy through relationships with female allies. These African predators, the largest members of the hyena family, weigh up to 190 pounds, and females are on average 10% heavier than males. Clans, some topping 100 animals, form complex societies.
