on land-surface temperature

in north China.

MY SHORT SUMMARY FOLLOWS:
Warming is caused by economic
growth and land use changes
near land based weather stations.
Cities are sometimes called
"heat islands".
Bian et al. (2017)
studied urbanization
on land-surface temperature
in Shijiazhuang, north China,
versus two less-urbanized
nearby locations, from
1965 to 2012.
There was an urban-rural
linear trend difference
of 0.27 °C per decade,
suggesting
"that the increase
in annual mean
land surface temperature
at the Shijiazhuang
station is probably due
entirely to urbanization."
