Email 4423, April 2009, warmists struggle to explain what happened with the weather in 1997-1998: "if not instrumental, then maybe an abrupt climate change bogie man came out of the closet to cause 0.5 offset after that time - any ideas? "

big divergence is during 97-98 ENSO - if it is some instrumental problem from the ocean, perhaps clues from this time interval could unravel why

if not instrumental, then maybe an abrupt climate change bogie man came out of the closet to cause 0.5 offset after that time - any ideas? might be too early to look that way unless ocean instrumental uncertainties are put to rest....  [Tom Crowley]
