Clearly Hansen doesn’t agree with you. What both Hansen and I found is that to within something like 1/100th of a degree there has been no change in ocean temperatures over the past 7 years.

As far as statistical significance goes, a trend of 7 years as I’ve shown is 1/2 as reliable as a trend of 49 years. Trends don’t have a magical threshold, where they are insignificant one year and significant a year later. A trend of 17 years is significantly less than twice as reliable as a trend of 7 years.
