Mark Serreze claims Arctic ice extent is the lowest on record for March
The Danish Meteorological Institute shows that Arctic ice extent is higher than 2006.
The animation below compares maps from 2006 and 2015. There is substantially more ice than 2006. Note that the University of Illinois changed their eye-altitude since 2006, due to an error I found in their maps in 2008. This causes some distortion, but I lined the maps up as closely as possible.
