GLOBAL WARMING, page-101

Oh, sure. You can say that. But you'd be confusing the variation due to long term trends, with short term natural variability.

Global temperatures had declined steadily since the holocene maximum around 8,000 years ago, until we started warming things with CO2. By even the most outlying paleo-historical temperature reconstruction we have out-done that 8,000 years of cooling with just around a hundred years of CO2 warming.

Short term natural variability of Arctic sea ice and what you are talking about are totally different beasts.
