Shocking video from Greenland -- where an estimated 12 billion tons of ice melted in a single day

Mother Nature is sounding the alarm on climate change. Images of Greenland’s historic ice melt are going viral after Pulitzer Prize-winning journalist Laurie Garrett shared video on Twitter of flooding waters in Greenland, where extreme high temperatures are being recorded this summer.

Watch this video after the fold below, and see what climate scientists are saying about the severe climate change happening before our very eyes.

Climate scientist and glaciologist Ruth Mottram, who studies Greenland and the Arctic, noted Greenland has lost 11 gigatonnes of ice. That is 24,250,848,840,336, or 24 quadrillion pounds of ice.

Just how much water is that? Here’s climate scientist and Arctic permafrost expert Martin Stendel with the terrifying figures.

ENOUGH WATER HAS MELTED IN TWO DAYS TO ENTIRELY COVER FLORIDA IN FIVE INCHES OF WATER. Meanwhile, in Florida today:

Climate scientist Robert Rohde lays out how serious the situation is historically, given that two of these historic records have come in the last seven years.

And it appears it will only get worse, as conditions are just right to accelerate the melt.

Rep. Ilhan Omar spoke out after viewing the video, saying, "The climate crisis is an existential threat to humanity. It is time for us to mobilize accordingly." And she’s right. This isn’t just an environmental threat; it is a matter of national security. Look at the chaos and disruption brought about by Hurricane Katrina, when the city of New Orleans had to be evacuated, and many people were permanently displaced. What happens if the unthinkable becomes a reality and large numbers of Florida residents are driven out of their homes? Or residents of New York City and other large coastal cities? Already the beaches of Florida are eroding at historic rates due to storms that are more frequent and devastating due to climate change. That means that climate change is an economic threat as well. Florida’s tourism industry generates $67 billion a year.

We have ideas to fix this, and we must immediately get started. Those who mock the Green New Deal and stand in the way of saving the world must be driven out of office as fast as we can do it. The time to act was yesterday. As Rep. Alexandria Ocasio-Cortez said, “We don’t have time to argue. We need to act—on a massive scale.”
