Air Gets Worse
The latest “State of the Air” report by the American Lung Association finds air quality has worsened so much that nearly half of people living in the U.S. now breathe unhealthy levels of air pollution. Soot and smog are on the rise in part because climate change heat is bringing more wildfires and low-level ozone-forming conditions.


NOAA Climate Science Cuts
A key climate modeling program within the National Oceanic and Atmospheric Administration or NOAA is slated for near-elimination, according to a draft White House memo. That could have consequences for weather forecasting, disaster preparedness, agriculture, military operations and more.


Parrot Brains and Our Own
Parakeets have astounding vocal abilities and are able to mimic as many as 1700 human words. And their brains may provide insight into how we humans talk. In a recent study, researchers found human-like neural activity during vocalization. They hope this research may help shed light on communication disorders in humans such as autism.
