Avian flu, that’s for the birds!
But, not only the birds: A study by the U.S. Geological Survey and St. Jude Children’s Research Hospital, shows that the avian influenza H3N8 strain that infected New England harbor seals could be transmitted to other mammals through the air without physical contact.
Did you get wind of the geomagnetic storm?
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave and/or cloud of charged particles,which interacts with the Earth's magnetic field. Space weather phenomena associated with, or caused by geomagnetic storms include: Solar Energetic Particle (SEP) events, geomagnetically induced current (GIC), ionospheric disturbances, and auroral displays at much lower latitudes than normal.

A Canary in a Coal Mine?
Well into the 20th century, coal miners brought canaries into coal mines as an early-warning signal for detecting toxic gases. Coal use in the United States began around 2,000 years ago, when early inhabitants of this continent probably gathered coal from outcroppings, beaches, and streambeds. Coal mining by European-Americans began in Virginia, in the Richmond Basin, between 1720 and 1750. Our Energy Resources Program maintains Coal Databases.
What do glaciers and pigs have in common?
They both have snouts. Glaciers periodically retreat or advance, depending upon their mass balance. This is their snow accumulation balanced against evaporation and melting (ablation). Glacial retreat and advance refer only to the position of the terminus, or snout, of the glacier. To better understand the modern glacier environment, take a look at the photo Glossary of Glacier Terminology.
