During week 37, NSIDC ages Arctic ice by one year. Note how NSIDC aged the ice last year in Mid-September.
That means the Arctic is now largely full of multi-year ice. Except for new ice from the last couple of days, all of the ice is multi-year ice.
In 2009, experts announced the end of multi-year ice.
Year after year, NASA fraudster Gavin Schmidt says it is the hottest year ever, and that the Arctic is warming faster than any place on earth. Yet Arctic ice is growing.
Either Gavin is lying, or the freezing point of water has changed.
