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

Climate change isn't pretty. Floods. Droughts. Forest fires. Trillions of dollars to pay for it all. And that's just the tip of the (increasingly smaller) iceberg.

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.

Middle school has to be the most insecure time in a person's life. Kids in their early teens are incredibly cruel and will make fun of each other for not having the right shoes, listening to the right music, or having the right hairstyle.

As if the social pressure wasn't enough, a child that age has to deal with the intensely awkward psychological and biological changes of puberty at the same time.

Jason Smith, the principal of Stonybrook Intermediate and Middle School in Warren Township, Indiana, had a young student sent to his office recently, and his ability to understand his feelings made all the difference.

It begins with more inclusive conversations at a patient level

True

Adewole Adamson, MD, of the University of Texas, Austin, aims to create more equity in health care by gathering data from more diverse populations by using artificial intelligence (AI), a type of machine learning. Dr. Adamson’s work is funded by the American Cancer Society (ACS), an organization committed to advancing health equity through research priorities, programs and services for groups who have been marginalized.

Melanoma became a particular focus for Dr. Adamson after meeting Avery Smith, who lost his wife—a Black woman—to the deadly disease.

This personal encounter, coupled with multiple conversations with Black dermatology patients, drove Dr. Adamson to a concerning discovery: as advanced as AI is at detecting possible skin cancers, it is heavily biased.

To understand this bias, it helps to first know how AI works in the early detection of skin cancer, which Dr. Adamson explains in his paper for the New England Journal of Medicine (paywall). The process uses computers that rely on sets of accumulated data to learn what healthy or unhealthy skin looks like and then create an algorithm to predict diagnoses based on those data sets.

This process, known as supervised learning, could lead to huge benefits in preventive care.

After all, early detection is key to better outcomes. The problem is that the data sets don’t include enough information about darker skin tones. As Adamson put it, “everything is viewed through a ‘white lens.’”

“If you don’t teach the algorithm with a diverse set of images, then that algorithm won’t work out in the public that is diverse,” writes Adamson in a study he co-wrote with Smith (according to a story in The Atlantic). “So there’s risk, then, for people with skin of color to fall through the cracks.”

Tragically, Smith’s wife was diagnosed with melanoma too late and paid the ultimate price for it. And she was not an anomaly—though the disease is more common for White patients, Black cancer patients are far more likely to be diagnosed at later stages, causing a notable disparity in survival rates between non-Hispanics whites (90%) and non-Hispanic blacks (66%).

As a computer scientist, Smith suspected this racial bias and reached out to Adamson, hoping a Black dermatologist would have more diverse data sets. Though Adamson didn’t have what Smith was initially looking for, this realization ignited a personal mission to investigate and reduce disparities.

Now, Adamson uses the knowledge gained through his years of research to help advance the fight for health equity. To him, that means not only gaining a wider array of data sets, but also having more conversations with patients to understand how socioeconomic status impacts the level and efficiency of care.

“At the end of the day, what matters most is how we help patients at the patient level,” Adamson told Upworthy. “And how can you do that without knowing exactly what barriers they face?”

The American Cancer Society believes everyone deserves a fair and just opportunity to prevent, find, treat, and survive cancer—regardless of how much money they make, the color of their skin, their sexual orientation, gender identity, their disability status, or where they live.

People share experiences with intrusive thoughts.

When I was younger I used to think I was dying or that I would get kidnapped by a random stranger, but I kept it to myself because I thought something was wrong with me. I thought that telling people would confirm this fear, so I kept it inside my entire life until I was an adult and learned it was part of ADHD and other disorders, such as OCD and PTSD. But it doesn't have to be part of a disorder at all—a vast amount of people just have intrusive thoughts, and a Twitter user, Laura Gastón, is trying to normalize them for others.

'90s kids share movies that will 'take you back to a better time'

It was a magical time when animals played sports and yet somehow things were just simpler.

YouTube/Upworthy photo illustration

Honey, I shrunk the kid named Matilda while jamming in space!

Everyone knows that '90s movies just hit different. From sports movies to rom-coms to even horror, there was an undeniable innocence, without being overly simplistic or juvenile. They didn’t have nearly the amount of money going into production as they do today, but somehow managed to transport us to magical places.

Movies of the '90s are so iconic that there have been several attempts to reboot beloved titles. Which, let’s face it, tends to be a fool's errand at a cash grab. These movies are so timeless that simply viewing the original is more than fine.

Not sure which movie to start with? You’re in luck—a Reddit user by the name of YouBrokeMyTV asked ’90s kids to share movies that took them “back to a better time,” and because the internet can be a wonderful place, tons of people responded with some beloved classics.

These answers certainly don’t make a definitive list (there are just so, so many gems) but they're a fun glimpse into what made '90s cinema so special. A nostalgic romp through memory lane, if you will.

Enjoy these 14 titles that just might leave you jonesing for a rewatch:

1. "Honey, I Shrunk the Kids"

via GIPHY

A perfect example of how '90s movies were silly, but smart at the same time. And oh so wholesome.

2. "The Sandlot"

via GIPHY

It taught us nothing about baseball, but everything about friendship, rooting for the underdog and (most important) how to make s’mores.

3. "Drop Dead Fred"

via GIPHY

Critics might have run this cult classic through the mud during its inception, but audiences fell in love with the bizarre charm of this story about a mischievous little girl and her anarchist imaginary friend. So take that, snotfaces!

4. "The Goonies"

via GIPHY

Everyone just wanted to set off an epic quest with their friends for pirate treasure after seeing this movie.

5. Tim Burton's "Batman"

via GIPHY

Before the superhero genre was the behemoth it is today, a quirky director and the dude who was best known for playing the creepy demon in "Beetlejuice" breathed new life into comic-book movies. Marvel might be the leader on creating stories with adult themes that are digestible for kids nowadays, but this DC film was the first of its kind. Plus, that soundtrack … forget about it.

6. "Hook"

via GIPHY

Pretty much any '90s film starring Robin Williams was an absolute gem, but this one in particular is timeless. His gift of balancing childlike humor with emotional gravitas lent itself so well to playing the now grown and cynical Peter Pan, who must learn to reclaim his joy (relatable, millennials?). It was a bang-a-rang-er, no question.

7. "Space Jam"

via GIPHY

It had Looney Tunes, it had aliens and it had Michael Jordan. That’s a winning combination.

8. "Matilda"

via GIPHY

I don’t think I’m out of line when I say that this movie helped a lot of kids make their way through difficult childhoods.

9. "The Parent Trap"

via GIPHY

Even '90s reboots were awesome. And how fun it is to see that Lisa Ann Walker—the actress who played Chessy the housekeeper—is not only yet again gracing the screens in NBC’s “Abbott Elementary,” but is also being revered as a style icon on TikTok for her ultra casual looks in the film. We all knew she was onto something with long button downs and shorts.

10. "The Land Before Time"

via GIPHY


No cartoon, not even “The Lion King,” was a better depiction of childhood grief. And yet, despite encapsulating tragedy, director Don Bluth still left viewers hopeful. The subsequent 14 (yes 14) sequels definitely pale in comparison to the original, but "The Land Before Time" continues to stand the test of time nonetheless.

11. "Richie Rich"

via GIPHY

The scene where they play tag on four-wheelers is simply iconic.

12. "Dunston Checks In"

via GIPHY

Man, the '90s were the golden age of animal-centered films. And not just monkeys either—we got sports playing golden retrievers and not one, but two movies starring talking pigs. What a time to be alive. These films were made before CGI had reached the levels it’s at today, and the authentic interactions between humans and creatures reached right through the screen.

13. "George of the Jungle"

Watch out for the tree!!!

Have I seen this movie at least 20 times? Probably. It doesn’t get any better than this in terms of silly action films with bird puppets. It’s crazy to think that this role would eventually lead Brendan Fraser to "The Mummy" franchise, turning him into a household name. Though his career has had some tragic ups and downs, we are all grateful for the glorious comeback he’s been having.

14. Anything involving Mary-Kate and Ashley Olsen

Whether vacationing in London, Paris or Rome, whether playing magical witches or making a huge billboard so their father could find love … Mary-Kate and Ashley Olsen offered zany, whimsical entertainment while wearing fun outfits. Sometimes, that’s all you need.
