“Differences in the average daily temperature minima (nighttime) of San Antonio relative to New Braunfels for the summer months from 1946 to 1990 (dark line). The warming trend due to the UHI in San Antonio is shown by the red line, which represents a least-squares fit to the data.”
“The UHI effect itself may be an important contributor to the investigation of global warming. Most temperature measurements are made at weather stations located at airports, which are intense heat islands because of their long runways, terminals, large parking lots, and buildings. A question thus arises about the significance of these measurements influenced by the UHI in relation to global warming.”
