Thanx for this image Nikki. We don’t see nature in this light very often, especially true before satellite observation became a reality. To anyone interested in our changing sea-levels, the fact that the ice is moving, and breaking off to drift away, has been in our knowing for decades. The increase of volcanic activity in that area, being a consequence of an increase in Pedersen Current at our planet poles, is another matter, and one which we find has been a cyclical issue for many millennia. I read articles about these ice movements, and wonder why few scientist remark how much of it is actually going into our oceans. Not much, actually. Beside the fact that ice there, on the surface on that pole, is growing beyond what we’ve seen in our history, remember that the ice was floating before it came loose. The portion of ice, above the water, is the portion added to sea-levels. Remembering that ice expands, the amount of fluid above the water is slightly less water than the cubic footage. Nevertheless, it is still far less than the ice recently applied to the continent, which will flow to the sea, eventually, over the next many hundreds of years, like it always has. Unfortunately, the late snow in Canada, will still be there next winter, and the snow after that, will stay, and so on, until the northern hemisphere is blanketed, and the light reflected will allow cooling to cascade to our next cooling period, just as it always has, for thousands of years. In reality, global warming could save us, create new farming zones in Canada to help feed us, since plants need the carbon-gasses we expel, and heat could provide areas to live without being covered by ice for the next 156-years. I won’t even mention how much the Oxygen content of our atmosphere has changed since 1950. If you’d like to know more about what could be in our future, look-up ice core science, look at some of the graphs going back thousands of years and compare them to tree-rings of the great old-growth forest for the last 3,000-years. And then another problem is this new word, you may want to investigate: Obliquity Ecliptic or Changes in Obliquity of our planet, and you’ll see what will be in store for your descendants a hundred years from today or sooner. This chunk of ice is big, but it doesn’t hurt us, it’s normal, and has little impact on preventing sea-levels from falling by hundreds of feet as ice develops at the poles for the next 50 to 150 years between this 400-year cycle…as it has, for millions of years.
Additional information, I’d neglected to mention:
