Arctic Melt Update

August 22, 2020

May not be a record low year, but impressive melt nonetheless.
Stay tuned.

    What are the odds an a “lowest ever” minimum this year?

    This year’s melting season is unlike any previous year in recent Arctic history, so how much store should be placed in Samuel’s projections?

    This has never been done before for example:

    The ice extent statistics is something concrete that we can see from NSIDC
    and others, each month. It seems highly likely we will be sea-ice free in the summer, in the Arctic before 2050.

    But that is not the whole story – the story is also the thickness, albedo and quality of the ice. And the story is not very comforting.


    “The North Pole ice sheet has thawed so much that it has shattered, climate researchers have discovered.

    Scientists onboard the German research ship Polarstern yesterday reached the Earth’s northernmost point and said they were surprised by how freely the vessel could move in waters typically known to be frozen solid.”

    “For this region, the current situation is historic. Normally it’s wise to avoid the region north of Greenland because it’s home to the thicker and older ice and virtually impassable. But now we’re finding extended stretches of open water reaching nearly to the Pole.”

    Under a year ago the New Scientist was reporting a 4 million tonne loss – how quickly that news has changed …


    “Earth has lost 28 trillion tonnes of ice in less than 30 years

    A total of 28 trillion tonnes of ice have disappeared from the surface of the Earth since 1994. That is stunning conclusion of UK scientists who have analysed satellite surveys of the planet’s poles, mountains and glaciers to measure how much ice coverage lost because of global heating triggered by rising greenhouse gas emissions.

    The scientists – based at Leeds and Edinburgh universities and University College London – describe the level of ice loss as “staggering” and warn that their analysis indicates that sea level rises, triggered by melting glaciers and ice sheets, could reach a metre by the end of the century.”

    sorry for the typo 4 million should read 4 trillion ..

    New Scientist 10 December 2019.. . ..


    Greenland lost almost 4 trillion tonnes of ice in less than 30 years

    May not be a record year for extent, but so far it is for volume.

    Once those ice cubes disappear, the water will likely start warming sooner and faster, unless a lens of cool fresh water / ice prevents such a feedback (almost no ice to cool the surface water).
