In the American Southwest, winter snowmelt and summer rains play a critical role in ponderosa forests' survival, but the 23-year megadrought may have these semi-arid trees at the end of their rope, according to new research by UArizona scientists.

Andrew Ellicott (A.E.) Douglass graduated from Trinity College in 1889 and eventually became known as the “father of dendrochronology.”

In what appears as a classic case of scientific quarrel, a new study is cited by local environmentalists arguing that certain studies funded by the

During California’s drought in 2015, the state experienced exceptionally little snowfall, initially estimated to be the least in 80 years.

Climate models and geologic climate archives are at odds over whether Earth gradually warmed or cooled over the past few thousand years. The most comprehensive evaluation of evidence supports a cooling trend that lasted until industrialization kicked off the current warming trend.  

If a trees rings are studied in a lab but no one hears them, do they make climate research sounder? Musicians at the UA want to know.
