We found the [urban warming] effect is pretty big in the areas we analyzed.
Urban warming blocks the temperature at night from cooling.
A review of recent studies published online in December by David Parker of the Met Office concludes that, even allowing for Jones's new data, «global near - surface temperature trends have not been greatly affected by urban warming trends.»
This is close to the warming of 1.09 °C (0.86 — 1.31 °C) observed in global mean land temperatures over the period 1951 — 2010, which, in contrast to China's recorded temperature change, is only weakly affected by urban warming influences.
They conclude that «urban warming does not unduly bias estimates of recent global temperature change.»
We estimate that China's temperature increased by 1.44 °C (90 % confidence interval 1.22 — 1.66 °C) over the period 1961 — 2013 and that urban warming influences account for about a third of this observed warming, 0.49 °C (0.12 — 0.86 °C).
«We found that urban warming reduced carbon storage by all of Raleigh's willow oaks by 12 percent, or 27 metric tons per year,» Meineke says.
The analysis failed to detect the known urban warming at Fairbanks, Alaska (Magee et al. 1999), whereas the analysis using near - surface winds did so
The research on scale insect abundance is published in «Urban warming trumps natural enemy regulation of herbivorous pests,» which is forthcoming from the journal Ecological Applications.
The researchers then plugged these results into a model to determine the extent to which urban warming impacted carbon storage for all of the willow oaks in Raleigh.
«Urban warming slows tree growth, photosynthesis.»
«Earlier studies have shown that urban warming increases pest abundance in street trees,» says Emily Meineke, lead author of a paper describing the work.
«Wavelet analysis shows that this relative urban warming trend was primarily manifested in the form of multi - decadal and interseasonal cycles that are likely attributable to gradual increased winter heating in Ottawa (heat island effects) associated with population growth.
As there are other potential sources of error, such as urban warming near meteorological stations, many other methods have been used to verify the approximate magnitude of inferred global warming.
The results are consistent with other recent studies from Frank's lab, which showed that two species of scale insects infesting maple and oak benefit from urban warming.

New research from North Carolina State University finds that urban warming reduces growth and photosynthesis in city trees.
«We wanted to know how urban warming and pest abundance affect tree growth, since trees pull carbon out of the atmosphere and convert it into biomass.
Indeed, it contradicts Hansen et al., 1999's own (correct) claim quoted above that «[urban cooling] effects are usually outweighed by urban warming.»!
The new analysis combines sea - surface temperature records with meteorological station measurements and tests alternative choices for ocean records, urban warming and tropical and Arctic oscillations.
The main reason that 1998 is relatively cooler in the GISS analysis is its larger adjustment for urban warming.
Re # 4, Hansen et al say «We find evidence of local human effects («urban warming») even in suburban and small - town surface air temperature records, but the effect is modest in magnitude and conceivably could be an artifact of inhomogeneities in the station records.
Instead of eliminating the urbanization effects, these wrong - way corrections makes the urban warming trends steeper.
NASA GISS obtain much of their temperature data from the NOAA who adjust the data to filter out primarily time - of - observation bias (although their corrections also include inhomogeneities and urban warming - more on NOAA adjustments).
