chicomarxbro writes "A Y2K error discovered by blogger Steve McIntyre in August forced NASA's climate chief James Hansen revise temperature data showing 1934 was actually the hottest year on record, not 1998 as previously announced. This spurred renewed calls for NASA's Goddard Institute for Space Studies (GISS) to publicly release their historical FORTRAN code which powered the global temperature analyses. Still used today, the code has a lineage going back to the 70's. NASA finally agreed and published the code but not before making an unannounced change to the raw temperature data which bundled with the code. NASA's change to raw data collating methods. which hadn't been modified in over a decade, resulted in 1998 being put back in first place next to 1934. Some bloggers have called this stealthy revision of the raw data an "Enron like accounting game""
