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.

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

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 finally starting to treat climate change like the global crisis that it is — and you can help get the point across to them, too.

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.

When "bobcat" trended on Twitter this week, no one anticipated the unreal series of events they were about to witness. The bizarre bobcat encounter was captured on a security cam video and...well...you just have to see it. (Read the following description if you want to be prepared, or skip down to the video if you want to be surprised. I promise, it's a wild ride either way.)

In a North Carolina neighborhood that looks like a present-day Pleasantville, a man carries a cup of coffee and a plate of brownies out to his car. "Good mornin!" he calls cheerfully to a neighbor jogging by. As he sets his coffee cup on the hood of the car, he says, "I need to wash my car." Well, shucks. His wife enters the camera frame on the other side of the car.

So far, it's just about the most classic modern Americana scene imaginable. And then...

A horrifying "rrrrawwwww!" Blood-curdling screaming. Running. Panic. The man abandons the brownies, races to his wife's side of the car, then emerges with an animal in his hands. He holds the creature up like Rafiki holding up Simba, then yells in its face, "Oh my god! It's a bobcat! Oh my god!"

Then he hucks the bobcat across the yard with all his might.
