Justify your assumption that the icecaps over Greenland will melt.
Global average temperatures the past ten years have decreased. Before that, over the entire previous century, they rose - AND FELL - continuously over the same 1/2 of one degree range.
Today, global temperatures are 2/10 of ONE degree higher than baseline - and that “baseline” was at the one of the coldest periods in the entire century.
Greenland ice is stable, increasing in the center of the island. Recent melts near the edge have stopped ( in places), reversed (in places) and been steady (in places.) Antarctica ice in increasing.
Minor misunderstanding here: During the Medieval Warm Period - when worldwide temperatures were hotter than now but CO2 from man was negligible - Greenland was much warmer than now, and many crops and farms were successful for many centuries.
The island, however, while a bit warmer than now, was not underwater. The OCEAN LEVEL during the same period - when it was warmer globally than now - DID NOT RISE compared to today's level.
Rising sea levels, melting Greenland glaciers are a mindless propagandizing scare tactic used by the enviro’s to further their agenda. They CANNOT be justified by today's temperatures, temperature trends, not today's observations.
There isn’t anything in any of your links about Greenland flooding. And why would it flood during a cold period?
It was during the period when the entire area was under water! They Called it the Short warming period.... it happened... everybody left Greenland it couldn’t grow Food because it was a swamp like! If It was really hot maybe it could grow rice!
let me tell you what they say in Rye England in the 16th century The Pub i went to on sundays was a the Beach area Now One Mile From the coast! They Clainm That England is sinking in the North and Rye is on the Opposite end of that Phenomenom!
I wonder what the tectonic activity has been there (has the seabed been rising or falling?)
IIRC, ice that’s on land will cause the sea level to rise as it melts and adds its mass to the seawater.
I think you are misreading something. Most of Greenland (not counting ice) is well above see level running from hundreds of feet to thousands of feet. If all the ice in the world completely melted, it would only raise the sea levels 150 feet.
So how did Greenland get completely flooded c. 1600 AD without also flooding all of Florida and most of Southern England?
I think you are reading about one particular area of Greenland where warmer wheather turned the permafrost into mud.
“Why in the hell would the sea rise anyway?”
If you leave the hose running?
the article clearly stated they all left it was inhabitable..meaning you couldn’t grow Food! it was a marsh in warmer period!
Duh!
And you derived from this that Greenland was completely flooded exactly how? My father's farm in Missouri is a marsh in the Spring, that doesn't make it flooded.
Besides which, people didn't come to Greenland until 985AD, which was during the warmest period in the last 2000 years. All of those settlers' decendents were frozen out of Greenland by the Little Ice Age and were completely gone by 1500 due to the cold climate. So your "warm period" exodus (c.1600) doesn't make much sense.
Look If You can’t read the article I can’t explain it to YOU Sorry! what You wrote about your dads Farm has Nothing to do with a warm period in an Ice age..Thanks But Your Silt Theory doesn’t fly either Thanks!
Silt, as in the erosion and growth of shorelines, isn’t my theory. It happens. Its fact.
I don’t think that you fully understand what you have read, or you’ve read nonsense. You are stating that a warming period happened in the middle of the Little Ice age (1600AD), which managed to raise the Atlantic ocean hundreds of feet around Greenland but no where else, and that this flooding drove away settlers who had already died out over 100 years before. And then you get in a huff. Facts are stubborn things and in light of them I’m certain that I cannot align your statements with reality.
Where does the ice come from, another planet?
Ice is water, is ice, is water.
Doesn’t ice come from moisture already on earth?
How does ice get to be a larger area just because it changes from water to ice, visa-versa?
Does ice take up the same amount of space once it has melted back to water or does it get larger?
I’m just trying to understand. Anyone?
I was just wondering what it looks 5 years later.
If water evaporates off the ocean, the ocean level will drop and the water will be in the air. Now, when it snows onto land, that water (snow) is on the land and is still not raising the sea level.
Then the snow piles up, packs down, squeezes into ice..which—despite being compressed—is still greater in volume than it would be if it were liquid water.
Now, go mark the sea level.
Then, if that ice melts, the water flows off the land into the ocean, and sea level rises. Your mark will be higher after the warming. (Just like a glass of water filled to the brim will overflow if you melt an ice cube in your hand and let the water run into it...like ice melting from land would do to the ocean.)
Of course, that’s for ice on land, such as Greenland or Antarctica, and I have neglected factors like salinity changes, the expansion of liquid water with temperature changes, etc.
The Earth and her climate are not static, they change.
