Temporary carbon removal could help support climate goals, if used correctly

Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.

A decade ago, Bradley Markle, an assistant professor at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, noticed an odd pattern while sifting through temperature records from the end of the last ice age in Antarctica. The records seemed to defy prevailing theories of how temperatures vary across the Antarctic continent.

Johanna Harvey, an assistant professor of wildlife disease ecology at the University of Rhode Island, has described bird flu in public presentations as a quiet virus with loud consequences. Now, she's published a new paper in Wildlife Monographs, describing how circulating avian influenza viruses (HPAIV) show an expanded set of susceptible hosts, including many migratory wild birds, and higher transmission rates. In the paper, Harvey examines data gaps in avian influenza host dynamics to priorit

When a team of researchers recorded a low thundering underneath the surface of the Hudson River, they thought they were hearing the muffled rumble of trains. A closer look and listen led to a much more interesting discovery: The thunder came from Atlantic sturgeon—an iconic and endangered species—spawning in the depths of the river.
