The thermometer network is made up of a patchwork of non-research quality instruments that were never made to monitor long - term temperature changes to tenths or hundredths of a degree... Furthermore, land - based thermometers are placed where people live, and people build stuff, often replacing cooling
vegetation with manmade
structures that
cause an artificial warming (urban heat island, UHI) effect right around the thermometer.
