I can't quite understand this...
Surely the way science works is that:
1 - people gather data
2 - they write a paper describing their conclusions
3 - they publish the paper AND THE DATA, for other people to examine
4 - if no one can find a hole in anything, the conclusions are accepted
So, if we have an issue with ice coverage, where is the raw data, and any information on corrections applied, so that we can all examine it and determine if anyone is wrong?
Just one of the huge number of problems associated with climate science as practiced in the 21st century is that the base data is often not made public, but instead 'peer reviewed' by a few of your friends. Then a completely spurious claim is held to be 'proven'. Something like this: http://bishophill.squarespace.com/blog/2008/8/11/caspar-and-the-jesus-paper.html
