In Carson City, Nev., the average temperature for June, July and August has risen 6.8 degrees in the past 30 years. 

CARSON CITY, Nev. — Don Quilici has snookered a few Carson City newcomers through the years with bets that it would snow the week of his birthday in early May.

Unsuspecting gamblers often don't know that a sliver of the western Nevada city's boundaries extends to Lake Tahoe and encompasses Snow Valley Peak at a towering 9,214 feet.

"As an average, I'd win eight out of 10 years," said Quilici, 80, a Carson City native.

Lately, though, he hasn't been so lucky. That's because Nevada's capital city is getting hotter.

An Associated Press analysis of federal temperature records shows that Carson City has warmed more than any other city in the nation in the past 30 years.

The average temperature in Carson City has risen 4.1 degrees since 1984. Boise, Idaho, came in second, posting an average rise of 4 degrees. Las Vegas, known for its sweltering summers, was sixth, with an increase of 3.4 degrees.

But it's the boost in summer heat that really makes Carson City stand out.

The average temperature for June, July and August has soared 6.8 degrees in the past three decades, 2.2 degrees warmer than second-place Boise and 2.4 degrees higher than third-place Las Vegas.

The summertime average temperature is up from about 68 degrees to nearly 75.

Because the data on cities are based on one weather station and readings can be affected by urban heating and development, trends are not as scientifically robust as those of states or regions within states, but they do have value, said National Climatic Data Center monitoring chief Derek Arndt.

The change in Carson City is becoming noticeable in subtle ways.

Plants and trees are prone to blooming earlier, and more people are installing air conditioners. The systems were a rarity even a decade ago.

Nestled in a valley at the base of the Carson Range, the city is ringed by hills and mountains. And as the city has grown, more roads, asphalt, homes and commercial development have cropped up — ingredients for heat absorption and urban warming.
