You stated that "a ~0.6 deg increase across ~30 years [is h]ardly statistically significant". Ignoring the confusion between statistical significance and practical significance (as external criteria like the difference between the nominal temp and absolute 0 or the right criteria that I mentioned has nothing to do with statistical significance), you made a positive claim that it wasn't significant. > I gave three examples.
