This ice sheet is losing mass at a rather larger rate (around 220 cubic kilometres per year) and it will take only another 1 - 2 oC world warming to raise the summer melt zone to the top of the Greenland ice pack after which point, in my understanding, the ice sheet will go into irreversible melt.

In the couple of decades leading up to the most recent IPCC report, the ice sheets were losing slightly less than 0.001 % of their mass per year, a rate that would require more than 100,000 years to remove all of the ice, and the equivalent of me going on a diet for a year and losing about 1/3 of one potato chip.

Hunter and Brown calculated an average acceleration in the central projection of the IPCCs AR4 A1FI emission scenario (including scaled - up ice sheet discharge) of 0.002 mm per year over the period 1990 — 2010 (see the value plotted at 2000 in their Fig. 1, ref.

Thus, the concept of an emissions budget is very useful to get the message across that the amount of CO2 that we can still emit in total (not per year) is limited if we want to stabilise global temperature at a given level, so any delay in reducing emissions can be detrimental — especially if we cross tipping points in the climate system, e.g trigger the complete loss of the Greenland Ice Sheet.

Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year.

It means that the Arctic sea ice has continued to thin by 0.1 m per year since Rothrock et al. reported in 1999.

In 1996, the rate of ice mass loss had increased to 97 gigatonnes per year.

Given global greenhouse gas emissions of around 35 trillion metric tons per year, that suggests there won't be any Arctic sea ice in September by mid-century.

In the 1960s, the ice sheet was losing 100 gigtonnes of ice per year.

My formula works for any time period in the past near million years, your formula changes per period and doesn't hold for long periods of sustained high / low temperatures (ice ages / interglacials, even the MWP / LIA), because you have no limit in time... Thus simply said: your formula is wrong.

But in polar regions [within arctic circle] one is still going to have 6 months per year of darkness and therefore will still have freezing weather, though polar ice may not form during the winter.

This warming means that the sea ice, which naturally increases and decreases during the winter and summer seasons, is sticking around for 100 fewer days per year than it did in 1978.

Between April 2002 and April 2006, GRACE data uncovered ice mass loss in Greenland of 248 ± 36 cubic kilometers per year, an amount equivalent to a global sea rise of 0.5 ± 0.1 millimeters per year.

The most worrying changes are happening in Greenland, which lost an average of 375bn tonnes of ice per year between 2011 and 2014 — almost twice the rate at which it disappeared between 2003 and 2008 (see chart).

The ice mass loss observed in this research was a change from the trend of losing 113 ± 17 gigatons per year during the 1990s, but was smaller than some other recent estimates (Luthcke et al. 2006).

For eleven years, from 1993 to 2003, the Greenland ice sheet grew two inches per year, growing almost two feet in thickness.

Anyway, today we try to explain the exact opposite: how northern hemisphere ice ages can quite suddenly weaken — at least in case of the last one, which had its cold peak around 18,000 years ago, after which atmospheric CO2 levels «suddenly» (over a millennium or so) rose by 30 per cent, and temperatures started to climb closer * to our current Holocene values.

Glaciologists analyzed ice flow to the ocean from 1991 to 2015 in the Queen Elizabeth Islands, and found that surface melt grew by a whopping 900 percent, or 10 times, in the 10 years between 2005 and 2015, increasing to 30 gigatons per year by the end of that time.

As reported in Remote Sensing of Environment, from 1953 to 2010, the average rate of ice surface loss was 18 centimeters (7.1 inches) per year.

The up trend for the anomaly in sea ice from 1978 to end 2006 is 804Km ^ 2 per year.

According to study researcher Jürgen Determann, who like Hellmer is from the Alfred Wegener Institute for Polar and Marine Research, if the inland ice moves in lockstep with the ice sheet melting, it will mean an additional global sea level rise of 0.17 inches (4.4 millimeters) per year.

That increase in ice translates to about a quarter of a millimeter per year less sea level rise than was previously predicted, says lead author Jay Zwally, chief cryospheric scientist at NASA's Goddard Space Flight Center in Maryland.

However, despite this, the team reckon to have perhaps isolated a «global warming» signal in the accelerated run off of the Greenland Ice Mass — but only just, because the runoff at the edges is balanced by increasing central mass — again, they focus upon recent trends — a net loss of about 22 cubic kilometres in total ice mass per year which they regard as statistically not significant — to find the «signal», and a contradiction to their ealier context of air temperature cyclIce Mass — but only just, because the runoff at the edges is balanced by increasing central mass — again, they focus upon recent trends — a net loss of about 22 cubic kilometres in total ice mass per year which they regard as statistically not significant — to find the «signal», and a contradiction to their ealier context of air temperature cyclice mass per year which they regard as statistically not significant — to find the «signal», and a contradiction to their ealier context of air temperature cycles.

Ice core samples from before the industrial revolution show that carbon dioxide levels fluctuated, but did not exceed 300 parts per million in the last 800,000 years.

The MDB average rainfall during the last three decades has been recording a 10 % loss per decade, I believe this is primarily due to declining solar radiation levels, moving from the highest for 8000 years to presently the lowest for 100 years, this solar decline is expected to continue for at least another 3 decades, maybe 6 decades like it did in the 16th century, brining on the last little ice age.

If true, per our IPCC Polar climate briefers for the Polar Chapter all that is needed to revert to the normal ice age of the Quatenary is a trigger that causes 2 or so cold years in the N Hemisphere.
