Flipping the Switch (POP Part 30)

For quite some time I’ve stated that the fact that our planet is warming in the northern hemisphere is not solely the result of man made pollutants (although this is a contributor), but to natural forces.  

It is widely accepted among experts and the general public that the earth is presently in an Ice Age, albeit at the moment, an interglacial period that began about 15,000 years ago.  This Ice Age consists of cycles that average around 75,000– 80,000 years of glacial periods and 15,000–20,000 years of interglacial periods.  For an interglacial cycle to begin, the planet needs to become warmer until the switch flips once again that kickstarts the next glacial period.  

The next glacial period will occur when hurricane force winds increase in velocity that drive moist air higher in the atmosphere and further north where it then falls as colossal amounts of snow fall, so much so that the glaciers begin to grow once again instead of declining.   

If this switch does not flip soon, there is nothing to reverse the effects of the earths isostatic adjustment— a natural phenomenon resulting from the massive weight of glaciers during the last glacial period having depressed the earths crust in the Northern and Southern Hemisphere, with the equal and opposite reaction being to cause the earths crust to push out in areas close to the equator.  Another opposite reaction to the great weight of Glacial ice, was that the ice free edges of the affected tectonic plates, had bowled upward,… enough so that land rose up from the sea, … land that has since sunk back below the sea and to this very day, continues to do so.  AND that is why, those living along shorelines in the northern hemisphere such as eastern parts of Canada and the US, and islands like Cuba, need to be concerned with the fact that these areas are falling back into the sea.  The only thing that will alter this natural course, is when/if the glaciers begin to grow once again.  

Experts have been claiming that this isostatic adjustment that threatens shore lines is not really much of a concern as it is slow and shorelines will not be affected much in the next 100 years or later, but the following excerpt from a CBC article below suggests otherwise— the experts are wrong and we need to do something now to avert sudden flooding … and likely tsunami’s.  

 Snowy days could be a rarity in Nova Scotia by 2100. Here's what it means

'We're really close to flipping that switch'

In the ocean, these higher winter temperatures have an effect as well.  

The Gulf of St. Lawrence is among the southernmost regions for sea ice in the northern hemisphere.

Until relatively recently, researchers thought an ice-free winter was unlikely. But in 2010, DFO scientist Peter Galbraith conducted ice surveys by helicopter and found no ice at all. 

"Before 2010, we thought models were predicting that it was going to take a long time before we see no sea ice, and so when it happened, it sort of took us by surprise.

The following year was ice-free as well, as was 2021 — meaning three of the four times there has been no ice at all since 1969 have been in the last 15 years.

Galbraith says scientists project that ice-free winters will be the norm by 2100, a phenomenon that's directly linked to rising winter temperatures.
