The world's record for lowest temperature was recorded on Antarctica in 1960, when it fell to −126.9°F (−89.8°C). Based on an analysis of 10 years of South Pole ozone vertical profile measurements, Hofmann et al., (1997) estimated that recovery in the Antarctic ozone hole may be detected as early as the coming decade.
