Here's the new sea ice poll for April.

In last months poll, from 11 votes the average was 4.1 million km2 with a standard deviation of 0.5 million km2.

Extent has varied between 9th and 3rd lowest over the last 3 weeks.
Volume is at 3rd lowest on the latest update from PIOMAS, while the combined SMOS and CryoSat dataset has volume at lowest on record for the time of year.

As a reminder, the minima since 2010 in millions of km2 from the daily NSIDC data are:

2020:    3.7
2019:    4.1
2018:    4.6
2017:    4.6
2016:    4.1
2015:    4.4
2014:    5.0
2013:    5.0
2012:    3.3
2011:    4.3
2010:    4.6

The thread will lock at midnight at the end of the month.

Must admit i am basing my predictions totally on weather forecasting experience rather than having any knowledge of climate science but i am expecting a very meridional flow throughout the next 12 months so would expect some serious WAA into the arctic at times, i have gone for sea ice minimum to bottom out lower than 2012 this time.
