A linear fit of all 11 years shows a cooling trend.

Since you don't see the point with the real climate data, here's a very quick simplified graph to illustrate why a linear regression trend taken from a statistical and physical anomaly is inappropriate handling of data. Note that this is an important consideration even if using a trend analysis technique like Mann-Kendall.

By your reasoning, I can claim that I have an 11-year (in magenta) downward trend of donut consumption, even though looking at the 10-year, 12-year lines, or whole dataset (navy) would give me a different result.

Look... has the global temperature for the past 11 years been going up or down?

Have a nice day.

Here is James Hansan's corrected GISS data from 2007. It shows that 7 of the 11 hottest years all occured beffore 1955 and the hottest years were in the 1920s.

Look at the black dots and not the red line 5 year smoothing. Clearly the equation for positive radiative forcing of CO2 is broken (3.5 X ln (X1/X0)
