Og 25% i 2014
Relative to the average of the period between 2010 and 2012, the scientists found that there was a 33% increase in sea ice volume in 2013, while in 2014 there was still a quarter more sea ice than there was between 2010 and 2012.
Bemærk dog den løgnagtig, uvidenskablige, politisk udmelding fra den varmist BBC:
But they say 2013 was a one-off and that climate change will continue to shrink the ice in the decades ahead.
Hvordan kan 2013 være en 'one-off' når 2014 også er en 'one-off' ?
