A large pip would require that the Earth changed on it's axis, or that the Sun had a major change to it's output.
Actually, if you ignore the expected seasonal fluctuations, it would appear that the line would be trending towards being very flat. That being the case it goes counter to what the Global warming alarmists would be predicting, and is absolutely in line with the thought that MCGW is pure BS.
It may be a tiny bip, but the ice extent anomaly was - 2 million square feet in mid 2011 and is now + 183,000 square feet. Its a rapid intensification of arctic and antarctic ice. It will be interesting to see what the anomaly will be in the next 6 months. I predict it will hover around normal for a long time. In any event, sea ice has been relatively constant since we started measuring it. This is the real story!
