Accounts For 33% – 75% Of Modern Warming

Urban heat from paved roads, buildings, and machinery can artificially inflate temperatures substantially above measured temperatures from non-urban areas.  This introduces a significant non-climatic warming bias into long-term records.

Heat from an urban (or highly populated) environment can artificially raise temperatures by as much as 3°C to 10°C relative to nearby rural locations.   This is true even for villages in the Arctic.

Back in the early days the NWS bought property and placed their weather stations in rural or suburbia. As development has encircled these stations, heat island effect is impacting meteorological stats. 

AGW goons fail to convey that fact.
