MASIE Proves Yearly Arctic Ice Recovering
You will be hearing a lot about 2015 having the fourth lowest minimum Arctic ice extent ever recorded.
Here is what they are not telling you:
MASIE has very helpfully provided their records for the last ten years. Since stormy weather can affect both maximum and minimum ice extents, emphasis on March and September averages can be misleading. From a climate change perspective, a better metric is the average ice extent over the entire year. By that measure we gain a realistic perspective on the last ten years of Arctic ice fluctuation.
While Arctic ice varies a lot seasonally, the graph shows that it is not that variable annually during this decade. Fluctuating about +/- 4%, there was a slightly increasing trend, particularly in the last five years. Here are the ice extents in M km2:
Year | Annual Average | March Average | Sept Average | Sept Minimum | March Max |
2006 | 10.667 | 14.260 | 5.831 |

There’s another opinion on Arctic sea ice extent. It seems a more informed one.

Alarmists like to take their start point from the century sea-ice maximum of 1978, at the start of the ‘satellite’ era.
However, the IPCC shows satellite data from 1974-1979 when Arctic sea ice levels were similar to today’s extent.

P.s. Nice to see Tamino using ‘satellite’ data to confirm declining Arctic ice trend, when he scoffs at RSS / UAH TLT temp data, which confirm the 18+ year global warming pause.

Why don’t you post this on his blog and have some back and forth with him and his well informed commenters? I’m guessing you will be the one learning something. (Unless you’re in denial)

2015 is absolutely shattering the record for warmest year 2014.
That should give you “pause”.
