Huge iceberg collapse threatens Antarctic shelf: British scientists

An iceberg two-thirds of the size of Toronto has broken away from an
Antarctic ice shelf, leaving the shelf in danger of imminent collapse,
scientists with the British Antarctic Survey said Tuesday.
The berg is still moving, leaving a large part of the Wilkins Ice
Shelf on the Antarctic Peninsula supported only by a thin strip of ice
hanging between two islands.
Glaciologist Ted Scambos from the University of Colorado first raised
the alarm over the ice shelf, and colleagues at the British Antarctic
Survey recently sent a small plane on a reconnaissance mission to
check out the extent of the breakaway from the shelf. They confirmed
that the shelf broke away sometime over the past few days.
In 1993, Professor David Vaughan of British Antarctic Survey predicted
the northern part of Wilkins Ice Shelf was likely to be lost within 30
years if climate warming on the peninsula were to continue at the same
rate. Climate warming increases the volume of summer meltwater on
glaciers and weakens ice shelves.
"Wilkins is the largest ice shelf on the Antarctic Peninsula yet to be
threatened. I didn't expect to see things happen this quickly,"
Vaughan said in a release. "The ice shelf is hanging by a thread —
we'll know in the next few days or weeks what its fate will be.
The Wilkins Ice Shelf covered an area of 16,000 square kilometres (the
size of Northern Ireland). It was stable for most of the last century
but began retreating in the 1990s. A major breakaway occurred in 1998,
when 1,000 square kilometres of ice were lost in a few months. A
collapse of the shelf is not expected to have any effect on sea level
because it is already floating.
Antarctica has experienced unprecedented warming over the past 50
years. Several ice shelves have retreated in the past three decades,
with six of them collapsing completely.
The U.K. government-funded British Antarctic Survey researches global
environmental issues.

Was this iceberg formed back in the 1970s when they were predicting a coming

Happy to oblige.
Science magazine (Dec. 10, 1976) warned of "extensive Northern Hemisphere
glaciation."
Science Digest (February 1973) reported that "the world's climatologists are
agreed" that we must "prepare for the next ice age."
The Christian Science Monitor ("Warning: Earth's Climate is Changing Faster
Than Even Experts Expect," Aug. 27, 1974) reported that glaciers "have begun
to advance," "growing seasons in England and Scandinavia are getting
shorter" and "the North Atlantic is cooling down about as fast as an ocean
can cool."
Newsweek agreed ("The Cooling World," April 28, 1975) that meteorologists
"are almost unanimous" that catastrophic famines might result from global
cooling.
The New York Times (Sept. 14, 1975) said global cooling "may mark the return
to another ice age."
The Times (May 21, 1975) also said "a major cooling of the climate is widely
considered inevitable" now that it is "well established" that the Northern
Hemisphere's climate "has been getting cooler since about 1950."

LOL, and your links to these specific studies so we can read & verify them
for ourselves? I doubt it and thus we can we assume you've pulled these
from your ass, or was that famous climate scientist George Will's ass?

Talk about quoting text out of context:
"A model of future climate based on the observed orbital-climate
relationships, but ignoring anthropogenic effects, predicts that the
long-term trend over the next sevem thousand years is toward extensive
Northern Hemisphere glaciation."

Time, Newsweek & the NYT are NOT credible scientific journals, nor were
those sensational, unsubstantiated books like the "Weather Conspiracy".
There was NO CONSENSUS among climate scientist concering this global
cooling.
I again ask for you to supply the Scientific PEER reviewed articles showing
any kind of consensus amount climate scientist predicting global cooling
from the 1970's.

Nothing out of context at all. You don't like it, that's your problem.
> Time, Newsweek & the NYT are NOT credible scientific journals,
I'm sure you repeat the same line whenever they report on Global Warming....
right?
FWIW, they were reporting on the scientific consensus of the day. Back
then, it was a coming ice age. Now, it's global warming.
Chicken Little always seems to find a willing ear.
Do have a problem with reading comprehension? Do you know what
"anthropogenic" means?
"Anthropogenic effects, processes, objects, or materials are those that are
derived from human activities, as opposed to those occurring in natural
environments without human influences. Anthropogenic literally means
"producing man". The correct term for "produced by man" would be
anthropogenous.
The term is often used in the context of environmental externalities in the
form of chemical or biological wastes that are produced as by-products of
otherwise purposeful human activities."
http://en.wikipedia.org/wiki/Anthropogenic
So, this SINGLE article states that if you IGNORE all of effects of mankind,
ONLY look at the orbital-relationships and nothing else, the long term
effect over SEVEN THOUSAND YEARS, TRENDS toward Norther Hemisphere
glaciation. Gee, in CONTEXT that sounds a LOT different now doesn't it!

Nice Red Herring there my friend.

BS. Please provide the cites.....

Again, it's total BS. Please back it up with credible cites.
> Chicken Little always seems to find a willing ear.
Well, that explains you believing anything you read from wacko right-wing
sites which is where you pulled this crap.
>> FWIW, they were reporting on the scientific consensus of the day.
qwerty> BS. Please provide the cites.....
He can't, as it is a myth.
Mr. Carey is very fond of myths, generally confusing them
with verified data.

No. It sounds like they're predicting a coming ice age. Just like I said.
Oh, by the way, what are the effects of mankind? Significant?
Insignificant? Make it sooner? Later?

Your unwillingness to answer the question is noted.

You just saw them.

You just saw them. The fact that you're unwilling to accept it is a
personal problem.

I'm not the one predicting that the sky is falling. That would be your
friends.

No, it does not. It says when you DO NOT considering mankind and ONLY
consider orbital-relationships, ignoring all other factors, then possibly
over SEVEN THOUSAND YEARS there is a TREND toward glaciation in the Northern
Hemisphere.
> Oh, by the way, what are the effects of mankind? Significant?
> Insignificant? Make it sooner? Later?
It shows that the above SINGLE cite is sadly lacking any credibility.

When have I made any claim about Global Warming? Your attempt to change the
subject so as to avoid providing any credible cites to back up your BOGUS
clame is duly noted!

No, you posted a bunch of bogus stuff from some right-wing wacko site.
Please provide the LINKS to the articles in question. You've already
demonstrated that you cannot to quote from them properly.

What credible cites? You can make up any bogus crap, but if you don't
provide links to their sources then they have no credibility.

When did I claim the sky is falling? However, you'll believe anything
posted on a wacko right-wing site, no matter how crazy!
