Climategate: NOAA and NASA Complicit in Data Manipulation
by Joseph D'Aleo
...We don’t dispute the fact that there has been some cyclical warming in recent decades — most notably from 1979 to 1998 — but cooling took place from the 1940s to the late 1970s, again after 1998, and especially after 2001, all while CO2 rose. This fact alone questions the primary role in climate change attributed to CO2 by the IPCC, environmental groups, and others.
However, the global surface station data is seriously compromised.
There was a major station dropout — and an increase in missing data from remaining stations — which occurred suddenly around 1990. Just about the time the global warming issue was being elevated to importance in political and environmental circles.
A clear bias was found towards removing higher elevation, higher latitude, and rural stations — the cooler stations — during this culling process, though that data was not also removed from the base periods from which “averages,” and then anomalies, were computed....
...Actually Klotzbach et al. (2009) found that when the satellites were first launched, their temperature readings were in relatively good agreement with the surface station data. There has been increasing divergence over time (exceeding 0.4C now), but the divergence does not arise from satellite errors. Further, they found that the divergence between surface and lower-tropospheric measurements, which has probably continued, is consistent with evidence of a warm bias in the surface temperature record.
...Land temperatures trends were 0.31C for NOAA, versus 0.16C for the satellite measurements from the University of Alabama-Huntsville (UAH).
NOAA announced that June 2009 was the second-warmest June. In sharp contrast to this, GISS and the UAH satellite assessments had June virtually at the long-term average (+0.001 C°, or the 15th coldest in 31 years). Remote Sensing Systems (RSS — the other satellite measurement database) had June at +0.075 C°, the 14th coldest in 31 years.
NOAA proclaimed June 2008 to be the eighth-warmest for the globe in 129 years. Meanwhile, NASA showed it was the 9th-coldest June in the 30 years of its record in 130 years, falling just short of 2005.
Satellites were positioned by NOAA to be the future of temperature monitoring — but they amazingly are never mentioned in the NOAA or NASA monthly report...
