Antarctic ice shelf ‘hanging by thread’: European scientists

Breitbart.com – July 10, 2008

image This is quite concerning. Most of the instability in the ice shelves in Antarctica have been during the summer.  Now it appears that this shelf is in danger even though the continent is currently undergoing winter.  There have been a rash of shelves collapsing and Nobel Prize winner, Al Gore, spoke of this in his film “An Inconvenient Truth”. It is not conclusive why ice shelves collapse but it is important for us to explore these situations.

It appears that this shelf is being “eroded” underneath by warm waters.  This is likely the cause of the rapid failure of the other shelves as well.  Interestingly, some of the other shelves exhibited water pooling on the surface before their collapse but there is no mention of this situation in this article.

New Study: Global Warming Not The Only Factor In Arctic Ice Shelf Collapse

AHN – February 7, 2008

More studies and more contradictory conclusions! I feel like a broken record sometimes in this discussion of global warming and causality. As soon as one scientist puts out a hypothesis, another puts out a contradictory or modifying hypothesis. Perhaps the key thing to understand is that these aren’t facts but conclusions that have been reached by individuals.

A hypothesis (according to Dictionary.com) is:

a proposition, or set of propositions, set forth as an explanation for the occurrence of some specified group of phenomena, either asserted merely as a provisional conjecture to guide investigation (working hypothesis) or accepted as highly probable in the light of established facts.

35 Inconvenient Truths: The errors in Al Gore’s movie – Part 3 of 5

This is the third of a 5 part series reviewing the comments of the Science and Public Policy Institute (SPPI) in regards to “An Inconvenient Truth” (AIT).

You can read Part 1 of 5 here.
You can read Part 2 of 5 here.
You can read Part 4 of 5 here.
You can read Part 5 of 5 here.

ERROR 18 – I can’t find evidence for SPPI’s statement that the Arctic has increased  decreased in temperature 1 deg C in the last 60 years. SPPI falls victim here to the common Gore affliction of pointing out individual instances of information (ice bound ships) and assuming that this is conclusive data. I have called AIT out on this and I need to do the same with SPPI. Unless they can point to a reference for the temperature increase, I need to call this one spin.

Group: Global Warming Effects Hunting

CBS News – February 28, 2007

I have nothing but respect for the ancient ways of indigenous people on North America.  This article is quite moving and very inspirational.  The story of how Mr. Nattaq lost both of his feet to frostbite after a snowmobile accident should touch everyone that reads it. 

I am not surprised that the warming trend of the recent couple decades has caused a change in the ice formation of the Arctic.  I am not as easily convinced that this warming trend is the cause of mankind as this article portrays.  The article gives no scientific evidence of mankind’s interference but does detail how the warming climate has affected the Inuit.
