Oh No!
Yes, It's Another Antarctic Ice Post
10 Jul 2008
From a reader, comes yet another article claiming micro-climate
variations on the Antarctic Peninsula are indicative of global warming.
New evidence has emerged that a large plate of floating ice shelf
attached to Antarctica is breaking up, in a troubling sign of global
warming, the European Space Agency (ESA) said on Thursday.
Images taken by its Envisat remote-sensing satellite show that Wilkins
Ice Shelf is "hanging by its last thread" to Charcot Island, one of the
plate's key anchors to the Antarctic peninsula, ESA said in a press
release.
"Since the connection to the island... helps stabilise the ice shelf, it
is likely the breakup of the bridge will put the remainder of the ice
shelf at risk," it said.
Wilkins Ice Shelf had been stable for most of the last century, covering
around 16,000 square kilometres (6,000 square miles), or about the size
of Northern Ireland, before it began to retreat in the 1990s.
No, No, No. The Antartic Peninsula's climate is not indicative of the
rest of Antarctica or the rest of the Southern Hemisphere, much less of
the globe.
Here, one more time, is the missing context:
The Antarctic Peninsula is a very small area that has very clearly been
warming substantially over the last decades, but it represents only 2%
of Antarctica
The rest of Antarctica has seen flat and even declining temperatures, as
has the entire southern hemisphere. In fact, the Antarctic Peninsula is
a very small area that is anomalous within the entire Southern
Hemisphere, which makes it incredible that it so often is used as
indicative of a global climate trend.
Antarctic sea ice extent is actually at the highest levels observed
since we started watching it via satellite around 1979. Ice may be
shrinking around the Peninsula, but is net growing over the whole
continent
We have no clue how ice shelves behave over time spans longer than the
100 years we have watched them. It may well be they go through
long-term natural growth and collapse cycles.

"...and I think future generations are not going to blame us for
anything except for being silly, for letting a few tenths of a degree
panic us"
Dr. Richard Lindzen, Professor of Meteorology MIT and Member of the
National Academy of Sciences
"What most commentators-and many scientists-seem to miss is that the
only thing we can say with certainly about climate is that it changes"
Dr. Richard Lindzen
[most of the current alarm over climate change is based on] "inherently
untrustworthy climate models, similar to those that cannot accurately
forecast the weather a week from now." Dr. Richard Lindzen |
