Study: One-third of plant and animal species could be gone in 50 years
February 13, 2020 – Accurately predicting biodiversity loss from climate change requires a detailed understanding of what aspects of climate change cause extinctions, and what mechanisms may allow species to survive. A new study by University of Arizona researchers presents detailed estimates of global extinction from climate change by 2070. By combining information on recent […]

Declining snowpack over western US mapped at a finer scale
December 12, 2018 – Researchers have now mapped exactly where in the Western U.S. snow mass has declined since 1982. The research team mapped the changes in snow mass from 1982 to 2016 onto a grid of squares 2.5-miles on a side over the entire contiguous U.S. A person could practically find the trend for […]

Study finds very few pages devoted to climate change in introductory U.S. science textbooks
April 30, 2018 – As an ASU graduate student, Rachel Yoho wanted to push the boundaries of renewable energy research. What she didn’t fully anticipate is that it would also lead her to questioning how climate change is taught in today’s universities. In the Biodesign Center for Environmental Biotechnology, led by director and ASU Regents’ […]

Jet stream changes since 1960s linked to more extreme weather
January 16, 2018 – Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, droughts, wildfires and flooding, reports a University of Arizona-led team. The research is the first reconstruction of historical changes in the North Atlantic jet stream […]

Forest fires in Sierra Nevada driven by past land use
Nov. 15, 2016 – Forest fire activity in California’s Sierra Nevada since 1600 has been influenced more by how humans used the land than by climate, according to new research led by University of Arizona and Penn State scientists. For the years 1600 to 2015, the team found four periods, each lasting at least 55 […]
