Quantifying the Influence of the Urban Heat Island Effect - Background

Technical Rating: star
Major global temperature indexes are adjusted to correct for the effects of urban development. R. McKitrick and P. Michaels analyse the pattern of warming over the Earth's land surface compared to local economic conditions. They found a statistically significant correlation between the adjusted temperature data and economic development, meaning that the adjustments are not adequate to remove the urban heat island effects. They conclude, "If the contamination were removed, we estimated the average measured warming rate over land would decline by about half."

New Scandal Erupts over NOAA Climate Data

Technical Rating: star
A volunteer group headed by meteorologist Anthony Watts had found serious problems with US surface temperature monitoring stations. Not only did sites fail to meet the NCDC's requirements, but encroaching development had put many in ridiculously unsuitable locations -- on hot black asphalt, next to trash burn barrels, beside heat exhaust vents, even attached to hot chimneys and above outdoor grills.
