2012 wasn't bad measurement, it was actually visible from space. Also, cyclones in the Arctic is nothing special, 2012 was hefty, because the ice was already very thin and the ocean absorbed a lot of heat.
I didn't say it was. I said it was an outlier.
Cyclones in the summer are rare.
It was also a major reason that the sea ice extent got as low as it did, and it's never got even close to that low again. It's not relevant to the long term or short term trend.
