According to a study recently published in the journal Science, and latched onto by USAToday, more than 400,000 years ago, Greenland was actually green. Yes, scientists say, the massive island was an ice-free landscape, and was perhaps even covered with trees.
This is important to know, avers study co-lead author Paul Bierman of the University of Vermont, because it tells us "Greenland's ice sheet is fragile.” Bierman stated: "All by itself, during a warm period very similar to today, the ice sheet melted away 400,000 years ago. That was without fossil fuel emissions into the atmosphere.”
An ice sheet melted “all by itself?” Here is a “scientist” telling us that we must immediately change our lifestyles and bankrupt our economies to prevent something that occurred naturally and without human influence 400,000 years ago!
After Greenland’s ice sheet turned to water, whined the climate alarmists, the sea-level rose at least 5 feet.
This caused the fish-wrap factory USAToday to solemnly observe: “This means that the ice sheet on Greenland may be more sensitive to human-caused climate change than previously thought – and will be vulnerable to irreversible, rapid melting in the coming centuries.”
Say what?! No, it means that the ice sheet on Greenland was provably sensitive to non-human-caused climate change (warming)…and that the melting is reversible…because that is exactly what occurred after the last melting, and why Greenland is more frozen than green today!
For some reason, the birdcage liner USAToday chose University of Pennsylvania meteorologist Michael Mann, who was not part of the study and whose “hockey stick” graph of global warming has been widely discredited, to review the “study.” Mann obligingly expectorated: "We are coming perilously close to some potentially critical climate tipping points.”

Although it was arguably warmer 1,000 years ago than it is now, “Greenland” was named as a smart real estate marketing device to attract settlement by the Danes. Outside of a narrow strip of land on the southern coast (and subject to warming by the Gulf Stream), there wasn’t a lot of “green” in Greenland. Still, the Canadian Maritime Provinces were warm enough to promote the cultivation of grapes and thus called Vineland by Eric and his buddies.
Land masses rise and fall like the tides only the time scales are different.
Holland’s land mass keeps falling because they keep pumping the water behind the sea wall. It has nothing to do with Global Warming.
Many cities of ancient history are now below sea level because the land mass has fallen. They have been below sea level for a thousand or more years. Long before the Industrial Revolution.
Man kind has much less influence on nature than the Alarmist would suggest.

Where I live in southern Maryland at one time there was a glacier two miles thick. At another time we had 200-300 feet of ocean above us.
According to NASA, earth's atmosphere weighs 5.1e+18 kg (= 1.124358e+19 pounds = 5.62179×10^15 US tons)
https://nssdc.gsfc.nasa.gov/planetary/factsheet/earthfact.html
Call it 11.2 quintillion pounds (avdp) or 5.6 quadrillion tons (US)
Specific heat of air is 1006 Joules per kilogram of air per degree centigrade.

Based on the atmosphere's known mass, and the known specific heat of air, it would take (5.1e+18 x 1006 =) 5.712×10^21 Joules to raise the temperature of earth's atmosphere by a single degree C.
The Little Boy atom bomb that was dropped on Hiroshima exploded with a force of about 15 kt. A thousand tons of TNT will release about 4.184e+9 Joules so 15 of them comes to 62.76e+9J. Divide that into the 5.712e+21 Joules and you get 91,013,384,321 -- 91 billion -- Little Boy atom bombs. That's what you'd need to heat the atmosphere by 1 °C.
Wikipedia says we've detonated a total of 2,121 nuclear weapons representing a combined yield of 540,849 kilotons. That's equal to about 36,000 Little Boy bombs. Which means we're about 90,999,964,000 Little Boys short of raising the planet's atmosphere's temperature by 1 °C.
And that's ASS-u-ME-ing 100% of the energy of explosion is converted to heat, so obviously even 91 billion is well short of the mark.
He did this routine over 30 years ago.
The earth is still here.
