I've never even heard/read anything about "local climate change" and rarely even UHI in mainstream media.
The messages that have been hammered home by most scientists (and activists) almost always are based around global warming - even if local stats and trends provide the reference.
Not to mention I think there might be one or 2 up who have relocated to places like Vancouver BC, Seattle, San Fran, LA and other major cities. Lets also not forget Lethal Weapon 4!
They are useful for communicating warming to the public. The 2 meter temp in urbanized areas is what the majority of people experience. Obviously scientists have to be careful to make the distinction of local vs. global climate change and sometimes they are not as careful as they should be. My personal weather station tracks closely with Sea-Tac airport so I think it is fine enough as a representative site for Seattle.
What bothers me more is that like all surface obs these ASOS stations are prone to sensor drift and bias but they don’t seem to have good QC measures in place to catch that early and it’s often the general public alerting the NWS to an issue.
