“Update: Thanks to an email from John S. – a patron of climateaudit.org – we have learned that the Russian data in NOAA’s GHCN v2.mean dataset is corrupted. For most (if not all) stations in Russia, the September data has been replicated as October data, artificially raising the October temperature many degrees. The data from NOAA is used by GISS to calculate the global temperature. Thus the record-setting anomaly for October 2008 is invalid and we await the highly-publicised corrections from NOAA and GISS.”

It is probable that Hansen did not goof this time.

It will be corrected and the mocking red area on the map in Russia will vanish.

Cooling is back on schedule.
