Those long, intense plumes of moisture in the sky known as atmospheric rivers are a vital water source to communities along the U.S. West Coast. In their absence, desiccating droughts can develop. But in their presence, they can cause extreme rain and floods that can disrupt travel, cause landslides, and trigger infrastructure failures.

New research from The Australian National University (ANU) and ARC Centre of Excellence for Climate System Science suggests natural rainfall variation is so great that it could take a human lifetime for significant climate signals to appear in regional or global rainfall measures.

NASA and the nonprofit Conservation International are partnering to use global Earth observations from space to improve regional efforts that assess natural resources for conservation and sustainable management.

Drier summers and a decline in average snowpack over the past 40 years have severely hampered the establishment of two foundational tree species in subalpine regions of Colorado’s Front Range, suggesting that climate warming is already taking a toll on forest health in some areas of the southern Rocky Mountains.

A new study published Wednesday in Science Advances introduces an innovative tool to help resource managers preserve Pacific coastal wetlands from rising sea levels.
