The southernmost continent is cooling
The
Vostok Station rests at the so-called "Pole of Cold" in the
heart of Antarctica. International climatology researchers have
used the station as a drilling point. The ice cores they've
extracted have become the subject of substantial controversy.
Some scientists say that they provide evidence of global warming,
while the Scientific Committee on Antarctic Research has expressed
concern that they were contaminated.
Vostok was able to
provide researchers with one metric this month that there is little
room to debate -- Vostok has suffered through the coldest April temperature in its recorded history.
Temperatures in Vostok
on Thursday hit -106 degrees Fahrenheit and have not been updated, as
the station is currently not responding. Typical temperatures
for April are a balmier -85 degrees Fahrenheit.
Amid the cold
wave at the birthplace of warming claims, a major geological event is
promising to add a wrinkle to the climate debate, handing AGW
advocates another opportunity to develop new theories to explain away
cooling. The volcanic eruption from the Eyjafjallajökull
volcano in Iceland may
worsen, according to Risk Management Solutions in Newark
Calif.
RMS says that Eyjafjallajökull eruptions may worsen
and additionally another Icelandic volcano named Katla is now
"probable" to erupt. Further eruptions would not only
disrupt air travel, but the climate. RMS predicts that the
Volcanic Explosivity Index (VEI) may reach more than 4; more than the
infamous Mount Saint Helens eruption.
The two largest
eruptions of the twentieth century measured 6 VEI -- the 1991 Mount
Pinatubo eruption in the Philippines and the 1912 Novarupta eruption
in Alaska.
VEI is a logarithmic scale, thus even if the
eruption reaches 4 VEI, as predicted, that's still a mere
one-hundredth of the ash that was ejected by Pinatubo or Novarupta.
Current theory says that such an eruption would not have a major
impact on the global climate.
AGW theorists, however, have a
propensity for coming up with novel explanations to try to preserve
warming theory in the face of cooling trends. Attempts have
been made to explain away Antarctica's cooling. One approach is
to say it is actually warming, using questionably estimated data
(extrapolated based on current satellite data and past weather
station measurements). A second attempt is to admit that the
southern-most continent is cooling, but that the cooling is due to
the ozone layer depletion.
The increased volcanic activity in
Iceland should be ideal for AGW advocates as it gives them yet
another opportunity to "make the model fit the data".
Expect possible claims in the near future that volcanic ash's cooling
contribution has been understated in past models.
