Greenland Ice Sheet Spiking Above 1981-2010 Mean, Yet Again

October 28, 2018October 28, 2018 Cap Allon

Off the back of substantial SMB gains over the last two years, the Greenland ice sheet looks set to continue that trend in 2018-19.

Large areas to the west and south-east are gaining RECORD LEVELS for this time of year.

Check out the latest measurements from October 27, 2018:

The Greenland ice sheet is growing again.

The Modern Maximum is over, welcome to the next Grand Solar Minimum.

Top: The total daily contribution to the surface mass balance from the entire ice sheet (blue line, Gt/day). Bottom: The accumulated surface mass balance from September 1st to now (blue line, Gt) and the season 2011-12 (red) which had very high summer melt in Greenland. For comparison, the mean curve from the period 1981-2010 is shown (dark grey). The same calendar day in each of the 30 years (in the period 1981-2010) will have its own value. (DMI)

As ice sheets grow a process called ‘calving’ occurs.

Calving is the breaking of ice chunks from the edge of a glacier and is normally caused by the glacier expanding — not melting!

It’s the sun, folks.
