Flattening (For The Most Part) Ocean Basin Linear Trends

I’ve moved to WordPress.  This post can now be found at Flattening (For The Most Part) Ocean Basin Linear Trends
############
The linear trends of the Global Combined and Sea Surface Temperatures have flattened in recent years. For those interested in which of the five major ocean basins--Indian, North and South Atlantic, North and South Pacific--has flattened the most, which is actually showing an increase, and which are now showing negative trends over the past decade, I’ve prepared the following three spaghetti graphs. The linear trends, Figures 1 though 3, were determined by EXCEL for the following three periods:
Figure 1 – November 1981 to December 2009 (from the start of the OI.v2 SST dataset)
Figure 2 – January 1995 to December 2009 (the past 15 years)
Figure 3 – January 2000 to December 2009 (the past 10 years)

The decadal trends and the coordinates used for the ocean basins are listed in Table 1.
