Can Greenland Ice Caps Collapse? Part 1 of 2 // Published on Aug 16, 2016

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 of the Sea Research Society.

‘In 1995, ten argentine soldiers witnessed a cataclysm that no other humans have even seen, one that has since altered our understanding of climate change’.

  1. John Davies says:

    It is easier to estimate if the global average temperature, especially of the Northern Hemisphere, is going to rise fast in the next 5 years or so. If it rises by, say 0.3 degrees Celsius then the Greenland Ice sheet will start collapsing, if the rise is smaller the Greenland Ice sheet will probably not start collapsing.

  2. The sound track and slide show have separated, which makes following slides harder. Needs more work on details to produce clarity of the issues I have been trying to raise with my slides. A rework is necessary to fix and tidy up what is being said.
