well seeing as the ice is thicker and bigger than it once was .. if it loses a few pounds whats the problem ? this yr again it's breaking all records and as it melts it will yet again push over to the n/h and cool it .. so in a way it's helping it's little bro the arctic ....cool the n/h and the arctic will grow ..

Graywolf: When you are 25, you don't want to accept the potential that in fact, we all hope you get old. See the analogy? 25??? spin that around and your closer! If I woke up with no pain I'd think I'd Died!!!!!

[ Snip ] 25??? spin that around and your closer! If I woke up with no pain I'd think I'd Died!!!!! Nearing seventy, I can certainly relate to that.

Wonderfully thought-out op-ed. Thanks for sharing Sig. I'm a teacher and an Air Force Reservist, so my circles run the gamut of alarmists to nay-sayers. I like to think of our climate as cyclical...there are warmer periods and there are cooler periods. Do we contribute somewhat to the current warming trend (or warming pause)? Perhaps. But as the author so adroitly points out we were already on a warming trend before it became a "crisis." At some point, we can expect to see things cool off again and even glaciate. If Astromet's predictions are even close to being accurate, this will happen sooner than later and ice extent at the poles will be the least of our worries.

www.bris.ac.uk/news/2015/may/ice-loss-in-antarctica.htmlAs I've tried to point out ( a number of times now) the measuring of warm bottom water ingress down the peninsula had reached as far as Ross by 2012. The above would appear to document what happens in the years after its arrival. So how long before we start seeing impacts from those massive ice cliffs of Ross Ice Shelf? Take an axe. Find a tall, tall tree. How much of the base of that tree do you need remove before it collapses?

The melting on/near Antarctica will continue as long as we are in an interglacial. The March of time prevails. You are a smart guy, do you really think what we are observing is different than other interglacial periods?

Astro is not predicting glaciation he is only predicting a cold spell lasting 30 years. Correct me if I'm wrong anyone. My apologies. I wasn't suggesting that Astromet was predicting glaciation, just that ice at the poles will be trumped by an extended period of global cooling. Glaciation is a part of the natural cycle (that was really my point) and will occur at some point in our planet's future--hopefully long after our children's children are but distant memories.

if the right combination of events coincide it could be at any time .. we just don't know what triggers it .. it could be this cold spell or one another 1000 yrs in the future .. but we do have a lot of events going on atm .. pole shift ,solar min to name 2

Looks like things will get interesting around max ice down in Antarctica as Nino should be beginning to hit peak values so messing with global circulation more?
To see ice levels down on most recent years hints at this change? We shall see as the last of the winter storms meet with the largest extent? With Ross Sea making up the bulk of the 'extra ice' it will be interesting to see just how far out the ice can push compared to previous years.
The findings of maximum ice cliff height make the retreat ( beyond the sill) even more problematic with the prospect of 300m ice cliffs ( 200m above max stable levels???). If anyone needed to know why we see decadal pulses of rapid seas level rise then you can now include the mega calvings/collapses we are about to witness!

Graywolf: I have read paleo papers that indicate sea level rise happens in spurts. AT least in previous interglacials.
One would only expect the Holocene to partially mimic past periods wouldn't one?

Well, Graywolf, the collapse you're expecting should be quite a doozy! Do you own a boat? Global Sea Ice: 11th Highest For This Day – Above the 1981-2010 mean. Antarctic Sea Ice: 2nd Highest For This Day – 1.2 million sq km above the 1981-2010 mean. Above 2 standard deviations. Arctic Sea Ice: 2nd highest since 2004; only 2008 was higher. Within 1 standard deviation. Source: sunshinehours.wordpress.com. -- Day 186
