400,000 Years Ago, Greenland Was Green, Which is Bad News Today
400,000 YEARS AGO, GREENLAND WAS ICE FREE AND MAY HAVE BEEN COVERED WITH TREES
It’s the month of July in the year 2023, and it’s the hottest month ever recorded in human history. There’s nothing to argue or disseminate about this reality. And no matter where you are as you read this, you are feeling that reality to one “degree” or another. But the only measurement we have, besides various kinds of thermometers in the air and the oceans, is history. And one thing scientists are focusing on now is the fact that Greenland was actually green, as recently as 400,000 years ago. And while that may seem fairly innocuous to read, it’s actually really bad news for us today.

WITH JULY THE HOTTEST MONTH EVER RECORDED, GREENLAND’S HISTORY IS BAD NEWS, SOON
While scientists aren’t entirely sure that Greenland was covered with trees, they are certain that 400,000 years ago that it was an ice-free, tundra landscape. Besides being academically interesting and a prod to some people’s imaginations, why is this bad news for us today? Because in terms of climate change and fluctuations, 400,000 years ago was pretty recent. And it means that the current ice sheet in Greenland today is fragile, and prone to melting at even the slightest increase in temperature. And as you can likely feel, we’re already subject to more than a slight increase in temperature across the globe.

IF THE FRAGILE ICE SHEET IN GREENLAND MELTS, THE WORLD’S OCEANS WILL RISE BY 5 FEET
Perhaps you are one of tens of millions suffering heat stroke. Maybe you’re breathing Canadian wildfire smoke in the US. Or maybe you are feeling record temperatures in Europe, Africa, Asia, Australia, or even on either of the Earth’s poles. Or maybe, as unlikely as the possibility is, you are watching the ice sheet melt in Greenland before your very eyes. And here’s where the bad news gets more definitive. If the ice sheet in Greenland melts most of the way, that will turn into a sea level rise (everywhere) of 5 feet.
That means every coastal city in the world will be underwater. That’s…. bad news.
