One such example of regional differences can be seen through the urban heat island and oasis effect.
This is seen most clear for stations affected by warming due to the urban heat island effect.
For instance, Atlanta's urban heat island now covers at least 17 square miles.
Improving the energy efficiency of these urban heat islands is not trivial.
A lesser heat island may also exist in the immediate downtown of Eugene.
For millions of people living in and around cities, heat islands are of growing concern.
These include the fact that many are in urban "heat islands", although allowance is supposedly made for this.
Because they are warmer, heat islands use more energy to keep cool, which raises costs and reduces air quality.

The effects of the urban heat island may be overstated.
