"The last decade was the greater Yellowstone region's hottest on record, according to a study released Tuesday by a pair of environment-oriented nonprofits."

"The study's findings show that temperatures over the past 10 years were 1.4 degrees above the region's 20th century average. Summers, in particular, averaged 2.3 degrees higher than summers in the past century.
