Sea Ice Volume Is Not Recovering

Andy Lee Robinson has updated his indispensable animation of sea ice volume – which makes the point yet again how dramatically northern sea ice is declining – despite the inevitable efforts of distorters and deniers.

Also worth remembering that for total area of ice, we are at a low that is historic over not just the satellite era, but at least 1450 years into the past.  Look at the figure on the right, derived in 2011 from temperature proxies which were then compared to ocean sediments – (different critters live in iced-over ocean vs open water) and consider that the so-called “recovery” of sea ice is just a tiny squiggle at the bottom end of a 150 year long slide.
