Related: About this forumJason Box - Greenland Is The New Black; Lowest Reflectivity On Record For High Altitude Ice
Jason Box returned to Greenland for a few days late in August, and was able to shoot the video above. Newest observations show the lowest reflectivity on record for Greenlands Upper elevations.

And theres this.
NBC News:
Spongy sediments under Greenlands ice sheet may accelerate its flow into the sea an effect that previous estimates of ice loss failed to account for, according to University of Cambridge researchers. They said that means the ice sheet may be more sensitive than previously thought to overall climate change, along with short-term events like heavy rain and heat waves.
The researchers said it was thought that Greenlands extensive ice fields rested on hard bedrock, but new evidence shows that soft sediments also are present. Those sediments weaken as they soak up water from seasonal melt, allowing the sheet to move faster to the sea, the researchers said. Greenlands ice sheet covers 660,000 square miles (1.7 million square kilometers) to a depth of nearly 2 miles (3 kilometers) at its thickest. A 2012 study found that the sheets melting was accelerating, and a 2013 study estimated that because of melting in Greenland and Antarctica, sea levels could be 2 feet higher when todays preschoolers are grandparents. The research was funded by the Natural Environment Research Council and published Monday in the journal Nature Communications.

(19,224 posts)1. I like to use wood ash from my wood stove to melt ice on my driveway
Nothing tears through hard-packed ice and snow like a dusting of black/grey ash. Not even commercial salt mixes compare.
And now we've "ashed" one of the largest ice sheets on the planet. What could possibly go wrong?

> sea levels could be 2 feet higher when todays preschoolers are grandparents
Wonder how much this new evidence is going to bring that date forwards?
Here's hoping for "as soon as possible" so that the people responsible for the
problem will start to feel the effects rather than living out their lives in wilful
ignorance & luxury ...
