NH Snow cover loss
« on: February 02, 2015, 10:30:45 PM »
Following on from some arguments about Antarctica vs Arctic in the other thread I went on a hunt for comparison between CMIP5 modelled and observed NH snow extent and found This presentation by Environment Canada.

This shows a fairly dramatic decline in June extent, which to me looks much more significant than the drop in Arctic sea ice at minimum, both in size, and in departure from model.  However April extent is pretty closely in line with the models.

Michael - thanks for this.
I'd long been looking for a decent overview of the various research groups' findings.
If ever you find an assessment of the consequent Albedo Loss as a % of anthro-CO2 I hope you'll post it.

Ramanathan et al: http://www.pnas.org/content/111/9/3322.abstract    - found ASI Albedo Loss to average 25% of the A-CO2 warming since '79, and I'd very much like to get the warming for Cryosphere decline as a whole.

Regards,
Lewis
