Ice sheet is NOT latest climate victim
The UK's ITV News is being misleading again. On 6
April, they reported that the Wilkins Ice Shelf on the
'left' side of the Western Peninsula, had finally
cracked.
This follows a previous ITV News report on 25 March
2008 with the title,Ice
sheet is latest climate victim which presaged the
Ice Shelf's imminent demise.
The Wilkins ice shelf covers 5,000-square miles, so
it certainly worth reporting - if anyone other than the
British Antarctic Survey (BAS) is interested in such
facts. Having reported last year that the Ice Shelf was
"hanging by a thread", the 6 April 2009 report was
about that 'thread' breaking.
That's okay as far as it goes, but then scientists
went too far when they claimed this collapse was
evidence of climate change.
No it isn't!
It's evidence that the volcanic activity on the
Antarctic Western Peninsular is being used
inappropriately to scare us.
In March 1998, satellite images
recorded a large breakup along the northern front of
the Wilkins Ice Shelf. A BAS press release, entitled
'Antarctic Ice Shelf Disintegration Underscores a
Warming World' misinformed us that climate change was
to blame. But, of course, it wasn't.
The press release read: "In March 2008, the Wilkins
Ice Sheet on the Antarctic Peninsula lost more than 400
square kilometers (160 square miles) to a sudden
collapse. Following that event, the Wilkins continued
to break up, even as the Southern Hemisphere winter
brought frigid temperatures to the fragile ice
shelf."
So, we are expected to believe that Antarctica, the
coldest place on Earth, where temperatures can drop
to between −80 °C and −90 °C (−112
°F and −130 °F) in the interior during the
winter, and would also be well below freezing point at
sea level, could be so influenced by a one or two
degree rise (to a temperature which is still well below
0 °C) as to weaken or melt several cubic miles of ice.
The idea is preposterous. It is also mendacious when
one considers that the Western Peninsular is the only
part of Antarctica where this 'global warming' is
taking place - and the only part of Antarctica where
there are volcanoes.
Global warming? My money is on the volcanoes.
Wouldn't you expect the BAS and their colleagues to
know about the volcanoes?
It seems they don't.
According to the US National Snow and Ice Data
Center. The break-up is "characteristic of
climate-induced ice shelf break-ups."
Professor David Vaughan of the BAS, who predicted in
1993 that the northern part of the Wilkins ice shelf
would be gone in 30 years, said in 2008:
"Wilkins is the largest ice shelf on the Antarctic
Peninsula yet to be threatened.
"I didn't expect to see things happen this quickly.
The ice shelf is hanging by a thread - we'll know in
the next few days or weeks what its fate will be."
"Climate warming in the Antarctic
Peninsula has pushed the limit of viability for ice
shelves further south - setting some of them that used
to be stable on a course of retreat and eventual
loss.
"The Wilkins breakout won't have any effect on sea
level because it is floating already but it is another
indication of the impact that climate change is having
on the region."
Well, it's nice to see he got that right.
