Matters arising from D'Aleo 3: The 1940s and the present.

The warming of the 1940s was not like the current warming. There are differences in observations and the model evidence supports the idea that while the 1940s was an outcome of natural variability, whereas the recent warming is externally forced.

Matters Arising from D'Aleo 2: The AMO & PDO.

Regarding the Atlantic Multi-decadal Oscillation (AMO). D'Aleo claims it "Looks like an awfully good fit. There is very little, if any, global warming." I've already pointed the following out to him. The Center for Atmospheric Research suggests that the major part of recent ocean warming in the AMO is due to global warming, once the global warming signature is removed the AMO is rather a small effect. So that source suggests that if warmer ocean waters due to the AMO are substantially responsible for loss of Arctic sea-ice, then it is global warming that is causing most of the warming.

Matters arising from D'Aleo 1: Opening comments.

Recently Joseph D'Aleo has posted a reply to Tamino's posts Cold Cherries from Joe D'Aleo and More Cherry Ice from Joe D'Aleo. D'Aleo's response is here.

The Loss of the Ellesmere Ice Shelves

In April 2001 the Journal "Polar Record" published a paper by Vincent, Gibson and Jeffries entitled: "Ice-shelf collapse, climate change, and habitat loss in the Canadian high Arctic." hereafter referred to as Vincent et al.
They started their discussion by stating:
