DENVER — Things are heating up all over, but Colorado is seeing some of the most dramatic increases in temperatures and humidity in the country.

Colorado ranks in the top 10 states for fastest warming summers, according to data released by Climate Central.

Greeley and Boulder are seeing some of the biggest changes.

Greeley is one of the top five cities that have seen the biggest increase in annual average days above 90 degrees since 1970. Greeley also made the top 10 for the biggest increase in annual average days above 100 degrees since 1970.

“Since 1970, summers have been warming in 45 of the lower 48 states. In many of these states, this warming is driven largely by nighttime temperatures getting hotter,” Climate Central said in the report.

In Boulder, summers are getting steamier. The city was ranked third in the country from cities seeing the largest increase in summer air moisture since the 1970s.

“[Global] warming over the rest of this century is projected to make summers across the entire U.S. much hotter,” Climate Central said.

By 2100,  Climate Central said summers are projected to be 7-10 degrees warmer overall — with some cities as much as 12 degrees warmer than they are now.

Denver’s average summer temperature is 85.5 degrees, according to Climate Central. It is projected to be 10.9 degrees warmer by 2100.
