22 min. video. W5: What happens when the permafrost thaws?

Almost half of Canada sits on permanently frozen land called permafrost, but climate change is causing it to thaw and erode rapidly. W5's Avery Haines investigates a looming ecological disaster that poses a threat to the entire world.

10 min. video. Massive Melting Event Strikes Greenland Due to Heat Wave

Image
GREENLAND — A "massive melting event" has affected Greenland’s ice sheet during a heat wave that has brought temperatures more than twice as hot as seasonal averages, according to Danish researchers cited by Agence France Presse. Since Wednesday the ice sheet has melted by close to 8 billion metric tons a day, twice its normal average rate during summer, according to tracking site Polar Portal website, which is run by Danish researchers. While this loss of volume was not as extreme as the largest single-day melting event in 2019, the researchers say the area over which melting took place is actually larger than two years ago. Fossil burning is not slowing; it’s increasing. All the projections of recent years have proven to be massive underestimates. The human race is incapable of prolonging it’s “last best chance.” The near future prospects are simply terrible.

3 min. video. Rain Falls at Greenland Ice Summit for First Time on Record

Image
When the ice is gone temperatures will increase quickly. Similar to a glass of ice water and a glass of water sitting in the sun. As long as ice is present the water stays cool even as the other warms. Once the ice is close to gone it is overpowered by the heat, and the water warms to the same temperature as the unchilled glass. Its raining in deserts and now Greenland place that doesn't get rain are now getting it while California runs dry 😑 if this keeps up soon the ocean will rise and will be flooding on coast

5 min. Earth Itself Warming 'Doomsday Glacier' on Top of Climate Change, Causing Massive Melting

Image
Climate change isn’t the only factor melting the Thwaites Glacier, according to a new study from the Earth Communications and Environment journal. Rather, the Earth itself may also be warming the massive block of Antarctic ice, which is colloquially known as the "Doomsday Glacier." According to the study, the crust beneath west Antarctica is between 10 to 15 miles or 17 to 25 kilometers thick compared with around 25 miles or 40 kilometers in the East and this means that substantially more heat from below can access the West than can access the East. The researchers found that a geothermal heat flow of up to 150 milliwatts per square meter can occur beneath Thwaites Glacier, according to the study’s lead author.
