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