The idea of stratosphere falling down through a storm's eye (which sucks down cold air) is impossible the way claimed by Roland Emmerlich.
 
Yet, there is truth behind Roland Emmerilch's "A Day After Tomorrow" assertions:

Many nations are rising this issue at the United Nations that is not fully addressed by the West.
 
 
These are the three reasons why Roland Emmerlich's chosen explanation for the cold Dryases is wrong
(i) for the instantaneous temperature dropping from warm to cold and (ii) its associated sea level jump:

1) The quantity of the ultra cold gas in stratosphere is infitesimally small as it sits between the thick atmosphere below and a complete vacuum of the space above. If you brings that gas down to a ground level pressure, its volume vanishes to almost nothingness. (It bears to be remembered, that if anyone of you has ever climbed Mount Everest, at the top of this mountain 2/3 of the earth's atmosphere is already below your feet: it is this precious and finite portion of air we are so mercilessly plundering and in need of oxygen conservation.)
 
 
 
 
 
 
 
 
 
 
 
2) The Boylean Laws of gas dynamics state that gas in low pressure is always cold. When the pressure of it is increased by compression, the temperature goes up. Thus, if the stratosphere hypothetically "falls down" through a hyper storm's eye, its temperature will be very close to the air temperatures at ground level, almost the same. The collisions of the gas particles in the atmosphere are ultimately controlled by the earth's gravity that holds our atmosphere captive to the planet. This results that the collisions are not entirely randomly distributed, but more collisions occur downwards. As such, the gas particles falling down get compressed and hence, warm up. On contrary, the few gas particles kicked up slow down as they get higher and de-pressurised, so they get colder. (Because of these, air temperature cools when one climbs higher, 1.5C for each 100 metres.) Also, any gas particle lost through storm's eye to lower atmosphere will find its almost immediate replacements from the top of air mass that rests below stratosphere. Hence, stratosphere is always cold and always stocked up with some ultra thin, ultra-cold gas sandwiched between the earth and the vacuum of the outer space.
 
3) The storm surges are only temporary events in the area of low pressure associated with a storm system and especially where winds whip water towards the land. The ascribed sea level jump which is accompanied by the sudden climatic cooling was permanent and as there were no winds associated, could not be ascribed to storm surge.
 
 
What we continue to iterate at the United Nations is that the sudden the Dryases that were accompanied by rapid climatic cooling (from a preceding warmth) were results of sudden Heindrich Ice Berg Calving Events from Foxe-Laurentide Ice Dome or Weischelian Ice Sheet and ice shelves that broke up each time when sea level jumped higher and bent them.
 
 
I recall the United Nations General Assembly of 2009 when I was invited by the Egyptians to come over there to explain my views to them in more detail.

Egypt has been greatly concerned about Greenland ice sheet causing sea level rise. Much of their agricultural land is located in Nile Delta which is only few feet above sea level in many places. Egyptians are very old cultural nation which has a long collective "memory" of the distant past. The Egyptians remember that in the ancient past their leaders always feared sudden climatic warmings and exceptionally good years being followed by extremely cold and dry years. They had independently come to think that the failing ice sheets (due to global warming) had caused these. So, if Greenland now warms up this will very soon see the melt water accumulation between ice dome's base and bed rock to chisel the ice dome off the bed rocks (as pot holes are filled by water and ice starts sliding over the rock on the water rather than staying anchored onto these surface irregularities). One of these recollections is a story of seven warm and wet years suddenly flipping into seven cold and ultra dry years when nothing grew. A wise, but distressed pharaoh was said to have seen a dream of these bad years coming after the exceptionally warm and wet years (which were omen of the bad times to arrive). He then commands his prime minister to construct a national feeding programme to collect the surpluses of the seven good years surpluses to the bad years to head off the approaching disaster based on many earlier incidences of similar too-good-to-be-true weathers. Pharaoh's program became a great success. A reflection of this event even getting included in the Pentateuch of Judaeo-Christian corpus of traditions. 
 
 
What the Egyptian leaders, then under President Hosni Mubarak had decided was two-fold approach to encounter the loss of Nile Delta:
 
1) To combine the Mediterranean sand banks into one continuous barrier by closing the gaps in between. (The Egyptian coast has vast sand banks similar to one that runs from Weymouth to Lyme Regis here in the UK.) This provides a potential natural dyke which allows for several metres sea level surge.
 
2) To redirect the river water from Nile at Lake Aswan to discontinue going north but redirect it to West. For the efficiency the river water is piped for drip water irrigation schemes in dry but fertile South West Egypt where there is rich soil, plenty of sun shine but no water anywhere. If Nile Delta is lost by sea level jump, the Egyptian food supply is secure from any sea level rises unless the river dries up completely. A minor amount of water is allowed to continue to supply water for Cairo in the north.
 
It may have been a Belshazzar's Party for us at the hospitality of the then-President Hosni Mubarak at his magnificent 260-acre residence in Montasah, Alexandria. We had a ballet performing for us from Moscow, operas from Milan and Madrid, and a philharmonic orchestra from Vienna to provide us a good deal of fabulous entertainment at the expense of Egyptian tax payers... I suppose, the plans of the Egyptian government are no longer confidential after the fall of the President. I just hope their good ideas did not die with his Presidency.
 
 
The main reason why the ice sheet land containment failure has not been recognised is that people predominantly think ice sheets in their static, stable state during the Holocene. But the warmed and wet ice sheets at the end of ice age, and the wild sea level fluctuations of the Pleistocene, remain in climate change class recognised by the UN General Assembly chairman "Paleofuture Risks", a climate change factors largely confined to the advanced climate change unknowns: the X-factor Box. The Western Nations can fairly be accused at the UN of being indoctrinated and being straight-jacketed by their academia and hence reluctant to challenge the conventions which would help to reduce the size of little-known items in the X-Factor Box.
 
Heindrich Ice Berg Calving Events (ice sheet land containment failures) were very large because as they produced clean ice (in comparison to ice bergs from the fjords which are dirty as ice is forced to meander through many narrow slits that snake between the mountains. Due to the thickness of Ice Domes, the ice is virtually dirt-free when it comes in large ice islands through ruptured perimeter. Warmed ice domes fail when an "ice sheet thrust" develops too great after melt water accumulation that has filled up pot holes that anchors ice to the rock. The debris content is more akin to Antarctic Ice islands than ice bergs from Greenland fjords. The ice bergs are much bigger and have grounded even to the ocean floor in places like Lomonosov Ridge (~2000 metres below sea level) in the Middle of Arctic Ocean and off-South West Coast of Greenland (~1000 metres below sea level). As the thick ice sheet is clean, the debris trail these bergs produced is small, but their ocean and atmosphere temperature altering impact was much bigger.
