David Parker has published a new, more detailed analysis in the latest Journal of Climate arguing that the urban heat island effect is not responsible for the measured global warming trend. As in his earlier work on this, Parker compared windy to non-windy days:
The trends in temperature are almost unaffected by this subsampling, indicating that urban development and other local or instrumental influences have contributed little overall to the observed warming trends.
(Roger Pielke Sr. has thoughtfully disagreed with Parker on this question in the past, so I look forward to his comments on the new Journal of Climate paper.)
