There have been and will continue to be stories on the new record minimum of arctic ice and how this is further proof of anthropogenic global warming. As we have blogged, the authors of the papers and media reporting on them have no sense of history and of the real factors involved in the global cycles of temperatures and arctic ice.

In the attached UPATED pdf we will use the excellent discussions of the NSIDC updated weekly on the sea ice extent and some of our own analyses previously blogged to show you much of this is cyclical and driven by the multidecadal cycles in the oceans, and influenced this summer by an unusual summer weather pattern.

This excellent animation by NSIDC from 1981 to 2007also shows how arctic ice has varied and moved in recent decades on an annual basis due to the global pattern changes.
