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.
I bring up the topic not just for funsies, of course, but because the maps 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.
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.
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!)
"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."
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.

Science confirms ‘Move in Silence’ trend might be the smartest way to achieve your goals.
TikTok's latest viral wisdom is backed by hard data—and it's making people rethink their communication habits. We live in a world of chronic oversharing. We post everything, from the routes we run (including screenshots as proof of all that hard work), to the pale-green iced matcha latte sitting at our desks or a present from a boyfriend (who will be tagged prominently, not secretly off screen). Who knows when, but our brains became wired for sharing: to record, to curate, and to post every second of our lives, then consume that of others to a disturbing degree. So, here's a radical idea: when it comes to goals and plans, try keeping them to yourself. It could be the key to making them a reality.
That's the message behind TikTok's massively popular "Move in Silence" trend, where creators like @noemoneyyy have cracked the contradictory code to success: Instead of broadcasting every big idea or project that runs through your head, if you actually want it to come to fruition, keep your plans to yourself until they're executed. And it's not just a trend; surprisingly, science also supports this muted approach.
"As a former oversharer who used to tell every single friend, every single family member, or a partner everything I was doing, I promise you things always work out better when you keep them to yourself," explains creator @noemoneyyy in a video that's garnered millions of views.
On a different video by @mandanazarfhami, she says, “I don’t care what you’ve got going on in your life: that dream job, that city that you want to move to, that dream person, that dream life, that dream anything. Literally keep it to yourself until it’s done.”
Commentors were quick to agree, with one person writing: “From a young age, I never told anyone my next steps. I also taught my husband and son to keep our private matters to themselves and just do things 💯Not many people like it, but who cares🌝🙌🏼🫶🏼”
Another chimed in, “This concept has changed my life for the better.” Others replied, “100 agree 💕” and “100%🙌🏼people can’t ruin what is silent, show results.”
In a study done by New York University, researchers found that people who kept their goals private worked on tasks for an average of 45 minutes, compared to the 33 minutes of work completed by those who announced their plans in advance. The twist? The people who shared their goals expressed feeling closer to finishing, despite doing approximately 25% less work.
NYU psychologist Peter Gollwitzer, who led the research, concluded that "once you've told other people your intentions, it gives you a 'premature sense of completeness.'" He also found that the brain is made up of "identity symbols," which create one's self-image. Interestingly, both action and talking about action create symbols in your brain, so simply speaking about a future plan or something you want to do satisfies that part of your brain. When we make our goals public, especially ones that matter to us and deal with our identity, our ability to achieve said goal is significantly reduced. As the old adage goes, "actions speak louder than words."
Stranger still, in his paper "Does Social Reality Widen the Intention-Behavior Gap," Gollwitzer notes that in order for this phenomenon to happen, one must truly care about their goals. "Ironically, this effect was only found for participants who are very committed to their goal!" PsychologyToday notes. "The lesson learned is that the more passionate you are about your goals, the more secretive you should be about them."

Another reason to keep quiet: If you're a beginner trying something new, sharing your plans could potentially open you up to criticism and negative feedback, which could deter you from even starting. At the University of Chicago, professor Ayelet Fishbach conducted studies to determine how positive and negative feedback affects the pursuit of one's goal. According to Atlassian, she and her team found:
"One example the researchers give is a math student who gets a good grade on a test. If she perceives it to mean she likes math, she will study harder. If, however, she sees the high score as a sign she is making progress in the class, she may ease up and study less." - Atlassian
We've all been there: excitedly telling everyone about your grand plans to backpack through Europe, the year you'll finally learn Spanish, or joining the group lesson at the tennis courts you always pass by… only to mysteriously lose all motivation a week later. Turns out, those lovely dopamine bursts that accompany every enthusiastic "That sounds great!" or "You should totally do it!" response might be precisely what's holding you back.
The good news? You don't need to become closed-off and secretive, a hermit on the top of a mountain who's afraid to share any part of themselves with the world. Research suggests that sharing your goals with one or two selected friends who can be trusted to provide meaningful support is still a good idea. Just hold off on the Instagram Live announcement until you've actually accomplished something substantial.
So, the next time you sit down to write your goals, whether they be a new year's resolution, the day's to-do list, or a five-year plan, think twice about sharing it with others. Give it time and you might have something better to share soon: the results.
Should you let a dog lick your face?
With nearly half of the households in American having at least one dog, there's a lot people need to know about them. Our furry friends come in wide variety of breeds, each with their own unique traits and needs. "Man's best friend" can be a guardian, a helpful worker, a loyal friend, and a snuggly companion, but there's one thing almost all dogs have in common: Licking.
Some dogs lick way more than others, but it's rare to find a dog who never licks anyone or anything. Many dogs communicate and show affection by licking, which is sweet—if a little gross—depending on how slobbery they are. There's a common saying that dogs' mouths are cleaner than humans', which is a bit hard to believe when you see what some dogs put in their mouths, but it is true? What does science say about dog tongues and saliva? Is a dog licking our face something we should worry about?

It turns out, the answer to whether a dog's mouth is cleaner than ours isn't super straightforward.
An 8th grader named Abby tackled this question in a science experiment that won her a Young Naturalists Award from the American Museum of Natural History in 2011. Her family had gotten a dog and her mom kept telling her not to let the dog lick her face because dog mouths are full of bacteria. Instead of arguing, Abby decided to find out herself if this was true.
"I hypothesized that human tongues would be cleaner than dog tongues," she wrote. "I thought this because humans brush their teeth at least once a day. I hypothesized that dogs' tongues would be dirty because they were always licking dirty things like garbage."
After diving into the research about bacteria that live in and on humans and dogs, Abby decided she had a testable hypothesis. But this wasn't any old middle school science experiment. She applied for and got a grant to the State Hygienic Lab at the University of Iowa, where she was assigned a mentor to work with her.
You can read the nitty gritty details of her experiment here, but here was her conclusion:
Many dogs will lick you if you give them the chance. Photo credit: Canva
"I concluded that dog and human mouth flora are very different. (Flora means the bacteria found in a mouth or anywhere else.) The bacteria found in human mouths are more similar to another human's oral bacteria than the bacteria found in a dog's mouth.
I also concluded that dogs' mouths are cleaner than humans' in some ways, and dirtier in other ways. Humans have more bacteria in their mouths than dogs do, based on the total number of bacteria. Most of the humans had a 'moderate' number of bacteria, and most of the dogs had 'few' bacteria. A possible explanation of this might be that dogs pant a lot, and maybe while panting, bacteria falls off their tongues along with their saliva. But dogs had more types of bacteria. The average number of different bacterial colonies in a dog's mouth was about 5.7. The average number of different bacterial colonies in a human's mouth was about 4.1. I think this is so because dogs sniff and lick a variety of things, like carpets, floors, chairs, grass, etc., so they pick up bacteria from many places."
But what about the licking of our faces? That's a bit of a subjective call, but Abby's results gave her some peace of mind:
"In conclusion, will I let my dog continue to lick me? The answer to the question is yes!" she wrote. "I will feel guiltless about letting my dog lick me because I found out that human and dog oral bacteria are different, so my dog's oral bacteria present no harm to me."

According to Colin Harvey, professor at the University of Pennsylvania’s School of Veterinary Medicine and executive secretary at the American Veterinary Dental College, comparing dogs' mouths to humans' mouth is "like comparing apples to oranges." As Abby found, the microbes in a dog's mouth are very different than those in a human's.
The American Kennel Club elaborates:
"Most of the bacteria in your dog’s mouth aren’t zoonotic, which means you probably won’t get a disease from a big old doggy kiss. There are exceptions to this. Dogs that eat a raw diet are at an increased risk of contracting salmonella, which can be spread to humans. You also probably shouldn’t share kisses with a dog that regularly raids the litter box.
In other words, kissing your dog is less risky than kissing another human, but that doesn’t mean that your dog’s mouth is necessarily cleaner than a human’s—they just have a mostly incompatible set of germs."

Keeping your dog's mouth healthy through regular teeth cleaning and dental check-ups can also help prevent issues that could potentially come from dog licks.
So there you have it. If your dog doesn't eat a raw diet and doesn't go snacking in the cat box (or some other equally fecal-bacteria-ridden place), their kisses are probably not going to hurt you. Guilt-free pooch smooches for the win!
Anyone can transform their relationship with waste.
In Japan, one of the first things you notice is how intense they are about recycling. Bins are guarded by two to three uniformed protectors who are quick to tell you if you’re doing things wrong. For a novice—especially one from America—that seems to be almost everything. The plastic plate wasn’t washed clean enough, you’re headed to the wrong bin (there are many, all with varying purposes), etc.. It can feel quite exhausting until you realize that Japan is a global leader in plastic bottle and e-waste recycling, with an impressive 86% and 70%, respectively. Compare that to the global recycling numbers: according to the Ellen MacArthur Foundation, about 30% of plastic water bottles (PET) are recycled globally and only 22% of all e-waste is formally recycled globally.
However, nestled in the lush mountains of Shikoku Island—the smallest of Japan’s four islands—is a tiny town that’s revolutionizing the trash and recycling industry. Welcome to Kamikatsu. All 1,400 residents here are so committed to zero-waste, they sort their garbage into 45 different categories and don’t even use garbage trucks. And their efforts have paid off: Kamikatsu received a remarkable 81% recycling rate—the highest in the world, thus far.
Kamikatusu's recycling techniques are well worth the effort. Kamikatsu Zero Waste Center
For perspective, Japan’s national average (for overall solid waste recycling) is only 20%. Germany is considered as the global leader in recycling household and municipal waste, with a recycling rate of 67%. Following Germany are Austria (58%), South Korea (59%) Slovenia (58%), and Belgium (54%). The United States rests at 32%, although it aims for 50% by 2030. In short, Kamikatsu isn’t just lapping the world’s global leaders: it’s redefining what’s possible.
Which wasn’t always the case. In the 1970s, there was nothing exceptional about Kamikatsu, in terms of recycling. According to ReasonsToBeCheerful: “The roots of Kamikatsu’s reuse revolution go back decades. During Japan’s postwar economic boom, the expansion of mass industry created huge amounts of waste, which increased from 6.2 million tons in 1955 to 43.9 million tons in 1980. In response, municipalities across Japan, including Kamikatsu, began to build incinerators to dispose of it all. But over time, concern grew about the pollution being created.”

The town’s transformation took years, beginning in 1991, when officials first tackled food waste by providing composters to every household. By 1997, they’d created nine categories for recycling:
This was the moment that changed everything for Kamikatsu, a significant cultural and logistical shift that laid the foundation for years to come. "It was tough because it changed their day-to-day duties," admits Akira Sakano, founder and director of Zero Waste Japan, "but people got used to it."

Today, Kamikatsu continues its goal to become fully zero-waste. The town closed down their incinerators, removed all garbage trucks, and now boasts a radical 45 categories for recycling.
But do you really need a 45-category system to cut back on waste? Of course not. Here are five practices anyone can adopt at home:
As we face mounting environmental challenges, Kamikatsu offers a powerful reminder: with community commitment and creative thinking, we can transform our relationship with waste. Are you ready to try?

No one likes doing the dishes, but the tedious chore is made much easier when using a dishwasher. However, an alarming amount of people have reported that their dishwashers can actually make the job harder because they don't properly fit their dishes.
Some stuff is just too difficult or annoying to clean by hand. Wine glasses always come out smudgy. Anything that had grease or oil on it will usually come out of the sink with a little leftover film on it. Big cooking dishes like pots and pans with food caked on there? Good luck. The dishwasher is the perfect solution, except a lot of these things frustratingly never seem to fit!
And that's where Twitter user Mike McLoughlin (@zuroph) comes in. McLoughlin made an observation about his dishwasher that would change the way he does dishes forever.
Raise that top dishwasher rack to the roof!

For a decade, the Irishman thought that the bottom rack of his washer simply was too small for his large dinner plates. Then he made an amazing discovery: The top rack is adjustable. I repeat, the top rack is adjustable!
In a now viral post on Twitter/X, McLoughlin wrote:
"I moved into this house in 2008. It always annoyed me that the lower level of the dishwasher wasn’t tall enough to fit my biggest dinner plates. Been handwashing them all this time. This week I discovered you can raise the upper shelf and all my plates fit fine. TEN FUCKING YEARS" he wrote on X.
You can also lower the upper shelf to accommodate taller glasses, wine glasses, etc. So depending on what you're trying to wash, chances are your dishwasher can be configured to make it fit. Check your dishwasher's owner's manual (or look it up online if you don't have it anymore) for instructions, but most models have some kind of small plastic lever that you push in order to adjust the height.
Mind blown!
The tweet went totally viral, and was shared over 14,000 times. It seems McLoughlin wasn't the only one who didn't know most dishwashers had this feature.
The "hack" (is it still called a hack if the appliance is doing what it is supposed to be doing?) blew people's minds:
"err, not only you mate. I've been in this house 4 years and didn't realise..." a user wrote.
"Woke up this morning. Saw your tweet. Leapt out of bed and feverishly emptied top rack of dishwasher. Viola! Rack move up," said another
But other people were basically like, "Seriously, dude?"
A handful of respondents to the post were not impressed by McLoughlin's discovery. Apparently, for some folks, the movable top rack is common knowledge.
While a group of others tried to one-up McLoughlin with stories of their own:
"18 YEARS! I've had mine 18 years and only just realised! I used to lie the plates down so they would wash! I'm raging and ecstatic all at the same time. Do you have any other helpful hints about how to live life efficiently?!" wrote a user named Toby.
How it feels to learn you've been using your dishwasher wrong for yaers.Giphy
But mostly, people were just thankful for the knowledge, and thankful that they wouldn't have to keep living in the dark ages any longer.
Wait until they find out that in many models, you can remove the top rack completely! It's often a little more complicated, but once you do that, a whole new world of washing options open up to you. Without the top rack installed, your dishwasher can probably fit your biggest and most challenging pots and pants.
Okay, go on and check your own dishwasher. You know you want to.
