According to a recently released study, at
the end of the last ice age, parts of an enormous ice sheet covering Eurasia
retreated up to 2,000 feet per day. That rate is the fastest measured to date, far
exceeding what scientists previously believed to be the upper limits for ice
sheet retreat.
In the new study, lead author
Christine Batchelor and her colleagues analyzed former beds of two major ice
streams across the Norwegian continental ice shelf dating back 15,000 to 19,000
years ago. Using ship-borne imagery, the team then calculated the rates of
retreat by studying patterns of wavelike ridges along the seafloor. They hypothesized
that the “orderly” ridge patterns they observed may have been created as
the front of the glacier bounced on the seafloor from daily tides.
Call me a skeptic, but this doesn’t
sound to me like “settled science.”
Nonetheless, Batchelor and crew
think the finding may shed light on how quickly ice in Greenland
and Antarctica might melt-- and raise global sea levels-- in a warming world.
Batchelor stated: “If temperatures
continue to rise, then we might have the ice being melted and thinned from
above as well as from below, so that could kind of end up with a scenario that
looks more similar to what we had [off] Norway after the last glaciation.”
According to a story in The
Washington Post, Eric Rignot, a glaciologist who was not involved in the study,
opined on it anyway, stating via email: “This is not a model. This is real
observation. And it is frankly scary. Even to me.” (Cue the voice of Elmer
Fudd. “Yes, it is vewy, vewy, scawy, Rignot.” Not.
The only thing the study proves
is that the
Earth warmed quickly and dramatically eons ago-- without any possible help from
man. Inconvenient truth: there were no factories, gas stoves, air conditioners,
lawn mowers, automobiles, cattle ranches, or any other possible “man-caused”
greenhouse gas generators 15,000 to 19,000 years ago.
Any other interpretation of this
“study”—and its alleged “findings”—would constitute anti-science bias…and
qualify as “fake news.”
