As we learn more about climate, the "settled" conclusions the global warming '[[alarmist]]s', appear more and more ridiculous.

Nonetheless, controversy has persisted over the influence of urban warming on reported large-scale surface-air temperature trends. <ref>http://climatesci.colorado.edu/2006/01/29/do-urban-areas-have-larger-long-term-temperature-trends-than-other-locations/feed/</ref>
