1) Our results do not contradict earlier studies suggesting that some regions of Antarctica have cooled.
Why? Because those studies were based on shorter records (20-30 years, not 50 years) and because
the cooling is limited to the East Antarctic. Our results show this too, as is readily apparent by
comparing our results for the full 50 years (1957-2006) with those for 1969-2000 (the dates used in
various previous studies), below.


＞It is hard to make data where none exist
仮訳：観測点のない地域のデータを推定するのは難しい

「存在しないデータ」なら"data which do not exist"。
「作り出す」という訳語も不適切。もともと論文の趣旨は直接の温度データがない部分をどうやって推定するか
ってことなんだから、推定の方法は問題になってもデータがないことは問題になりようがない。
