from urban heat islands is now believed to be less than 0.1 C, and in some parts of the world it may be more than fully compensated for by other changes in measurement methods.4 Nevertheless, this remains an important source of uncertainty.The

from 1906 to 1955 and 1956 to 2005... The data document a strong
urban heat island eff ect (UHI) and a
warming with increasing station elevation... About a quarter of all the records for the 100 - year period show a fall in temperatures... that the observed temperature records are a combination of long - term correlated records with an additional trend, which is caused for instance by anthropogenic CO2, the UHI or other forcings... As a result, the probabilities that the observed temperature series are natural have values roughly between 40 % and 90 %, depending on the stations characteristics and the periods considered.»

warming.

How is it that the conclusions of climate scientists can be called into question as a result of supposedly dubious statistical techniques, but the long history of nonsense
from the skeptics, (such as the Robinson et al paper that accompanied the politically motivated Oregon Petition, the corporate funded propaganda campaigns of the Global Climate Coalition, and the recent
urban myth that Martian «global
warming» disproves a human influence on earthly climate) tells us nothing about the integrity of the skeptic theory of climate?
