[American Thinker] 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."
