NASA Research Finds Last Decade was Warmest on Record, 2009 One of Warmest Years

WASHINGTON — A new analysis of global surface temperatures by NASA scientists finds the past year was tied for the second warmest since 1880. In the Southern Hemisphere, 2009 was the warmest year on record….

Here is the full story, but you better don’t believe a word of it, and here are the reasons why not (from wattsupwiththat.com):

 For more information about why the GISS data isn’t much to be trusted, particularly at the northern latitudes, see this article

GHCN – GIStemp Interactions – The Bolivia Effect

GHCN – Up North, Blame Canada!, Comrade

I hope that NASA will stuff that in their pipe and smoke it.  However, until NASA and its GISS (Goddard Institute for Space Studies) stop cooking the books, references to GISS temperature records at the website of the Friends of Lamont County will point to the following note of caution:

….No one in his right mind will base any decisions about the future on tools that cannot determine with acceptable accuracy what the present is and the past was.

• Reality check: UAH (University of Alabama in Huntsville) monthly globally averaged lower atmospheric temperature variations since 1979 as measured by NOAA and NASA satellites.

Update 2009 12 11:

The GISS temperature record can no longer be trusted.

On or around about Nov. 14, 2009, GISS began to use a new global temperature data set that deleted temperature records relating to the late 19th and early 20th centuries.  Not only that, but the temperature data that remained in use were adjusted downward for dates preceding the year 2000 (increasingly downward the farther back in the temperature record they go), thereby creating or exaggerating “warming” trends for individual locations.

A discussion thread at http://wattsupwiththat.com details the nature of the data fiddling.

From that discussion thread:

…See under “What’s New”:
http://data.giss.nasa.gov/gistemp/graphs/

“Nov. 14, 2009: USHCN_V2 is now used rather than the older version 1. The only visible effect is a slight increase of the US trend after year 2000 due to the fact that NOAA extended the TOBS and other adjustment to those years.
Sep. 11, 2009: NOAA NCDC provided an updated file on Sept. 9 of the GHCN data used in our analysis. The new file has increased data quality checks in the tropics. Beginning Sept. 11 the GISS analysis uses the new NOAA data set. ”

The “visible effect” of the new, manipulated data set is far greater than the quoted note implies.  The data changes were without a doubt manufactured to create a warming trend where none exists or to exaggerate possibly existing warming trends.

This is not the first time that the gate keepers of climate data were caught in the act of large-scale falsifying of existing data.

Such is the state of the art of the GISS temperature record in relation to any claims about global warming: you are better off not to believe a word of it.
