Reader Kevin O’Neill brought this to my attention. Leading Arctic expert William Carlson said that glaciers in Norway and Alaska lost half their size during the fifty years before 1952. Had that rate of loss continued, there would have been no glaciers left in Alaska or Norway by 2002. Given that there are glaciers remaining, we can infer that the rate of ice loss was slower in the second half of the century than it was in the first half of the century.
Real Science 
Works for me!
You do not understand! The more the ice melts the slower it melts! It is logarithmic!
If half the ice melted in fifty years then half of the remaining will melt in the next fifty so there should still be ice laying around for thousands of years because only half of the remaining ice can melt during any 50 year period!
Kevin said it is not linear!!!!!
I just make this SH## up to try to figure out WTF they are trying to get across!
Just like the weather that controls the ice the amount of ice in any region is variable and I would not expect any one region to represent any other region on the globe.
Those that do are Total F’n delusional idiots!
Kind of like extrapolating temperature records over a 2500 KMsq area. The difference between my place and the airport 40 miles away varies so much one would think they do not represent the same country let alone a small region within a state.
Precisely. Kevin O’Neill is a top-ranked double space scientist, so when he asserts without evidence that something is non-linear you can’t argue.
SPACED OUT is about it! Another waste of taxpayers money!
In case it is not obvious, I am not impressed with titles. During my working career I was the technician / trouble shooter!
In other words the go to guy when SHTF!
Oh, we should ask Kevin how human ears taste (maybe):

He sure was nice to to compliment Steve by claiming that everything Steve wrote was BS. Better Science is just what Kevin needs and let’s hope he visits here more often to help us ponder more non-linear calamity change science.
Not the same Kevin O’Neill who (allegedly) produced this “semi-formal proof” that “the North Pole has never been ice-free, not once in the history of the earth.” http://climatesanity.files.wordpress.com/2010/07/kevin-oneills-proof2.jpg
