areas 6 to 8 degrees Celsius
warmer than rural regions.

warmer than rural and suburban
areas.
UHI effects have been documented in city environments worldwide and show that as cities become increasingly urbanised, increasing energy use, reductions in surface water (and evaporation) and increased concrete etc. tend to lead to
warmer conditions
than in nearby more
rural areas.

areas are generally
warmer than surrounding
rural areas.

In built - up urban
areas the concentration of heat storing materials in buildings, roads, etc. such as concrete, bitumen, bricks and so on, and heat sources such as heaters, air - conditioners, lighting, cars, etc. all combine to produce a local «heat island»: a region where temperatures tend to be
warmer than the surrounding
rural land.

If this is the best such land
area surface temperature assessment system on the planet (covering, as well, a broad range of metropolitan, suburban, and
rural areas), and the quality of the system is now proven to be demonstrably more prone to error
than had been previously assumed — with the preponderance of error shown to produce the impression of
warming in excess of real conditions prevailing — what may be reliably inferred about surface temperature monitoring systems data from even less reliable thermometers all over the rest of the world?
That is because urban
areas are slow to
warm down during the night and retain their heat longer
than rural areas.

rural areas.
