Data Integrity Issues, Natural Variability and Climate Change

Global Climate Change Global surface data bases suffer from serious issues that produce a warm bias and render them useless for an accurate trend analysis Global surface data bases suffer from serious issues that produce a warm bias and render them useless for an accurate trend analysis Temperatures have begun to decline, and are negatively correlated with CO2 Temperatures have begun to decline, and are negatively correlated with CO2 Oceans and sun cycles and volcanism correlate far better with temperatures including the recent cooling Oceans and sun cycles and volcanism correlate far better with temperatures including the recent cooling

Data Centers and UHI NCDC has removed UHI adjustment (Karl 1988) from USHCN in version 2 (2007) NCDC has removed UHI adjustment (Karl 1988) from USHCN in version 2 (2007) NOAA GHCN and Hadley CRUT3v don’t specifically adjust for UHI which requires metadata (siting, population, etc) they don’t have. Instead they apply a C uncertainty per century to the data NOAA GHCN and Hadley CRUT3v don’t specifically adjust for UHI which requires metadata (siting, population, etc) they don’t have. Instead they apply a C uncertainty per century to the data GISS applied a satellite light based UHI adjustment to USHCN and attempts a global UHI adjustment but without good population data, McIntyre finds their adjustments for global urban areas are as often up as down GISS applied a satellite light based UHI adjustment to USHCN and attempts a global UHI adjustment but without good population data, McIntyre finds their adjustments for global urban areas are as often up as down

USHCN Change Point Algorithm NOAA’s NCDC replaced the USHCN urban adjustment with a Change Point Algorithms designed to detect “previously undocumented inhomogenieties”. NOAA’s NCDC replaced the USHCN urban adjustment with a Change Point Algorithms designed to detect “previously undocumented inhomogenieties”. It is better suited to detect sudden discontinuities signifying changes like station moves or large local land use changes It is better suited to detect sudden discontinuities signifying changes like station moves or large local land use changes It can’t be expected to find the slow ramp of temperature associated with urban growth or of the gradual land use changes identified by Runnals and Oke (2006).

Contamination of the Data Bases Numerour peer-reviewed papers ignored by the IPCC and the data centers have estimated that these problems with the observing networks may account for up to one half the warming since 1880 (Kalney and Cai, de laat and Maurellis, Pielke and Davey, Pielke et al (numerous), Lin and Pielke, Michaels and Balling, Michaels and McKitrick, Runnals and Oke) Numerour peer-reviewed papers ignored by the IPCC and the data centers have estimated that these problems with the observing networks may account for up to one half the warming since 1880 (Kalney and Cai, de laat and Maurellis, Pielke and Davey, Pielke et al (numerous), Lin and Pielke, Michaels and Balling, Michaels and McKitrick, Runnals and Oke)

UKMO and ENSO, NASA and PDO Prof. Chris Folland (Jan 2008) from the Met Office Hadley Centre said: "Phenomena such as El Niño and La Niña have a significant influence on global surface temperature” Prof. Chris Folland (Jan 2008) from the Met Office Hadley Centre said: "Phenomena such as El Niño and La Niña have a significant influence on global surface temperature” Hansen in 1999 said “We suggest that further warming in the United States to a level rivaling the 1930s is likely in the next decade, but reliable prediction requires better understanding of decadal oscillations of ocean temperature.”

Warming in recent decades smaller than assumed and are of a cyclical nature Temperature trends are exaggerated by many issues most notably urbanization and siting.
