9 min. video. What's hidden under the Greenland ice sheet? | Kristin Poinar

The Greenland ice sheet is massive, mysterious -- and melting. Using advanced technology, scientists are revealing its secrets for the first time, and what they've found is amazing: hidden under the ice sheet is a vast aquifer that holds a Lake Tahoe-sized volume of water from the summer melt. Does this water stay there, or does it find its way out to the ocean and contribute to global sea level rise? Join glaciologist Kristin Poinar for a trip to this frozen, forgotten land to find out.


"The aquifer water drives the crevasse all the way to the base of the ice sheet, a thousand meters below". "The Greenland ice sheet is huge, the size of Mexico. And it's ice from top to bottom is two miles thick". So...is the ice sheet thickness a thousand meters, or two miles??? BIG difference! (Unless the snow {aquifer} is over seven thousand feet.)

A much simpler and more accurate method of determiming the amount of glacial loss is the hundreds of millions of years of geological record. The ice caps have grown to cover europe and even canada in 2 miles of ice thrn receded to zero ice cap over and over again throughout the history of earth with water.

4 min. video. How Melting Arctic Ice Affects the Earth

Image
In June 2021, temperatures in the Pacific Northwest reached a high of 115°F and resulted in the deaths of nearly 200 people. Heatwaves are a natural phenomenon, but concurrent conditions can exacerbate their impacts. As Arctic sea ice continues to melt in a warming world, there is a ripple effect on the global climate. This woman is an icon. She's been saying this for so long. It's sad that it has taken us so long to listen There's no chance "elected" officials can move quick enough and as drastic as is needed. This world is a huge joke. Innocent people are victimized for the gain of others. The true criminals will never face justice in this life.

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
