average annual temperature?

There is contamination of the air in the bubble by water; different results are obtained if the ice is crushed or melted to obtain the air sample; it takes decades
for the air bubble to form; the raw data was smoothed out by a 70 year moving
average that removed the great
annual variability found in the 19th century and Stomata Index (SI) records; closer examination revealed a major flaw in the hypothesis because
temperature rises before CO2.
To illustrate the point, I've been through a quick exercise using the approach that groups such as GPWF favour — and that Kaufmann's research group adopted — of using
annual temperatures rather than any kind of smoothed
average, and looking
for the
