Shifting climate means Tucson could be feeling more like Middle East

According to NASA, the first six months of the year have been the warmest on record. Arizona is not immune to the warming, which is a clear sign of a shifting climate as the general trend continues to be up, not down.

The line in the graph below shows an average increase of days hotter than 105 degrees since 1970. In the '70s, there were about 10 to 15 of these hot days each year. Now we can expect 20 or more.

So far this year, Tucson has recorded 17 afternoons at 105 or higher. During an average Arizona summer (May through September), we have 22. In the days ahead, Tucson will add to that count as monsoon storm chances wind down and the heat winds ups.

The increased hot days means our average summer highs are going to start feeling more like Abu Dhabi, UAE than what is currently seen in Tucson.
