Paul Beckwith on the demise of Arctic sea ice

The latest from Paul Beckwith who has been very prolific

Demise of Arctic Sea-Ice

There is very little Arctic sea-ice left this year. The trend is a rapid decline to essentially nothing (- 1 million square km); the "blue-ocean event" as I call it (should have trademarked this).

If the ongoing massive cyclones continue to shred the ice over the next 4 or 5 weeks of this summers melt season than "nothing left" could be this year; otherwise before 2020 is an excellent wager.

The devil is in the details; I teach you how to find the details (images) that you need to do your own assessment.

Can Greenland Ice Caps Collapse?

Is it possible that vast portions of Greenland's ice cap could calve/slide off the continent, causing spikes in global sea level rise? As we lose Arctic sea-ice and snow cover and get much warmer northern temperatures, how much would this destabilize Greenland ice?

I look at ice melt evidence/behaviour from 21,000 years ago to the onset of the Holocene to try and assess present day risks from Greenland, using slides from my friend Veli Albert Kallio.
