The MSM will explain it this way:
It’s a temporary short term phenomenom. El Nino is causing the Northern Hemisphere to be colder than normal this year. If it wasn’t for global warming, the November ice growth would have been even greater.
There’s that damn word....average...Now, we all know how you get an “average”, right?? You keep some numbers that look good, throw out some that look bad, keep some because you think they’re more truerer, throw some out because they mess up the answer....THEN....you toss all the numbers in a fish bowl....and pick the one up your sleeve.
