Did you know there are glaciers in South America?

There are, and they're beautiful! The Patagonian ice fields, located in the southern Patagonia Andes of Chile and Argentina, are the largest ice mass in the Southern Hemisphere with the exception of Antarctica, and the third largest freshwater reserve in the world.

While ice, snow, and glaciers might not be what comes to mind when you think of South America, near the southernmost part of the continent, that's exactly what you'll find.

Photojournalist Mario Tama recently visited the ice field, capturing the beauty of the ice formations alongside the signs of the toll climate change has taken on the area.

The southern ice field is roughly five times the size of Rhode Island.

The southern ice field is made up of roughly 50 glaciers and runs across parts of Argentina and Chile.

In 1937, Argentina established Los Glaciares National Park to preserve a vast region of Patagonia.

It's unique ecosystem combines things like waterfalls, rivers, forests, and, yes, glaciers.

UNESCO inscribed Los Glaciares National Park as a "World Heritage" in 1981.

UNESCO describes the park as "an area of exceptional natural beauty, with rugged, towering mountains and numerous glacial lakes."

The U.S. National Parks Service explains this phenomenon (and how you can experience it for yourself):

"Because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears. So... why is snow white? Light does not penetrate into snow very far before being scattered back to the viewer. However, the next time you are in an igloo, notice that it is blue inside. You can also poke a stick into some snow, shade the area around the hole, and look deep into the snow pack. The light that has traveled some distance through the snow will be enhanced in blue."

Between 2000 and 2012, these glaciers melted at a rate roughly 1.5 times faster than ever previously recorded.

Melting occurs throughout the glacier, and while it may not be completely uniform in pattern, recent studies suggest it's becoming more normalized throughout. Which means the whole glacier is starting to melt at roughly the same rate.

The rapidly melting glaciers are leading to rising sea levels.

Melting of glaciers and ice caps are the biggest contributors to rising sea levels around the world. As glaciers melt, the freshwater stored within gets dumped into surrounding bodies of water. If unchecked, this could pose disastrous consequences for people around the world.

As is the case for other glaciers around the world, it's climate change that's driving the melt-off.

Glaciers and other ice structures are some of the most impressive natural storers of climate information. As glaciers have been around for a very long time, they've existed through warming and cooling periods. Recent data extracted from glaciers, however, shows that the modern melt-off is different from naturally occurring fluctuations.

Some say it's too late to stop the melting, but that doesn't mean we should give up.

Dr. Ian Joughin of the University of Washington explained to the New York Times that climate change has destabilized glacier-covered areas, and without a stabilization mechanism, we'll continue to see glaciers melting.

Climate change is very real, and in addition to wiping glaciers from the earth, there are other dire consequences.

Rising sea levels may make some currently populated places totally uninhabitable. Additionally, due to climate change, the world can expect to see an increase in unseasonable and unpredictable storms, more droughts, and more heat waves.

But there are things we can (and should) do to help stop it. Like urging politicians to take action.

Over the next two weeks, 150 world leaders are meeting in Paris to discuss what we, as human beings, can do to preserve our planet and fight climate change. Some individuals don't believe we should take action, and some even doubt the reality of climate change (although 97% of the world's climate scientists assure humanity that yes, it is very real).

But meaningful change starts with letting our elected officials know that yes, this is an issue worth prioritizing for the sake of our world and generations to come.

So before the glaciers say their final "goodbye," let's do something about it!

Artist uses AI to create ultra realistic portraits of celebrities who left us too soon

What would certain icons look like if nothing had happened to them?

Mercury would be 76 today.

Some icons have truly left this world too early. It’s a tragedy when anyone doesn’t make it to see old age, but when it happens to a well-known public figure, it’s like a bit of their art and legacy dies with them. What might Freddie Mercury have created if he were granted the gift of long life? Bruce Lee? Princess Diana?

Their futures might be mere musings of our imagination, but thanks to a lot of creativity (and a little tech) we can now get a glimpse into what these celebrities might have looked like when they were older.

Alper Yesiltas, an Istanbul-based lawyer and photographer, created a photography series titled “As If Nothing Happened,” which features eerily realistic portraits of long gone celebrities in their golden years. To make the images as real looking as possible, Yesiltas incorporated various photo editing programs such as Adobe Lightroom and VSCO, as well as the AI photo-enhancing software Remini.

“The hardest part of the creative process for me is making the image feel ‘real’ to me,” Yesiltas wrote about his passion project. “The moment I like the most is when I think the image in front of me looks as if it was taken by a photographer.”

Yesiltas’ meticulousness paid off, because the results are uncanny.

Along with each photo, Yesiltas writes a bittersweet message “wishing” how things might have gone differently … as if nothing happened.

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.

At 1:30 am on Monday morning an AMBER Alert went out in southern Louisiana about a missing 10-year-old girl from New Iberia. It was believed she had been kidnapped and driven away in a 2012 silver Nissan Altima.

A few hours later at 7 am, Dion Merrick and Brandon Antoine, sanitation workers for Pelican Waste, were on their daily route when they noticed a vehicle that fit the description in the alert.

Nurse turns inappropriate things men say in the delivery room into ‘inspirational’ art

"Can you move to the birthing ball so I can sleep in the bed?"

Holly the delivery nurse.

After working six years as a labor and delivery nurse Holly, 30, has heard a lot of inappropriate remarks made by men while their partners are in labor. “Sometimes the moms think it’s funny—and if they think it’s funny, then I’ll laugh with them,” Holly told TODAY Parents. “But if they get upset, I’ll try to be the buffer. I’ll change the subject.”

Some of the comments are so wrong that she did something creative with them by turning them into “inspirational” quotes and setting them to “A Thousand Miles” by Vanessa Carlton on TikTok.

“Some partners are hard to live up to!” she jokingly captioned the video.
