GISS Land-Ocean Index dives in Jan08, exceeding drops for UAH and RSS satellite data 11 02 2008
Goddard Institute for Space Studies (GISS) Land-Ocean Global temperature index data was released yesterday for the month of January, 2008. Like we’ve reported before for other datasets, including the RSS and UAH satellite temperature anomalies, GISS also had a sharp drop in January.
The ΔT of -.75°C from January 2007 to January 2008 appears to be the largest single year to year January drop for the entire GISS data set.
This is yet one more indication of the intensity of planet-wide cooler temperatures seen in January 2008, particularly in the Northern Hemisphere, which has seen record amounts of snow coverage extent as well as new record low surface temperatures in many places.
