Perhaps I was tuned into that because of where I lived in my 20s: in the Mojave Desert. Out there, most people didn’t have air conditioners: they were too expensive to operate and they would be overpowered by the ferocious desert heat. The common form of house cooling was with evaporative coolers, also called swamp coolers. On the hottest days, it was also bone dry, so the evaporative coolers worked great.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Over the decades, more residents moved into the area and had lawns. I recall hearing the old timers note that swamp coolers were not working as well as they once did. I also knew that if a neighbor turned on a sprinkler in the middle of the day, one’s swamp cooler would lose a degree or two delta. I used to keep data on this kind of stuff for a side business: emergency swamp cooler repair and high performance swamp coolers.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>It stands to reason to me that increased irrigation could result in slight increases in water vapor in the air, which would trap additional heat. Most of us have been in out on a cool clear evening when a cloud cover rolled in and felt the temperature rise as the cloud trapped radiated heat. We know the effect can be localized. It is easy to imagine some of the historic temperature monitors being effected by nearby irrigation.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>spike<o:p></o:p></span></p></div></body></html>
