That wasn't specifically my point, but it's reasonable interpretation.
I haven't personally seen the data either way, so I can't comment in
detail, but it's my belief that the fluctuation of annual average
temperature is on the order of a couple degrees. (It would be nice
to see the data you refered to. Is it available online?) On that
basis, a "per-decade" change of 0.05, when the per-year change is
more than an order of magnitude larger, is not very convincing either
way.
