From EARTH Magazine (AGI), March 20, 2017 -- The Arctic looks pretty inactive during the winter, but more may be happening than meets the eye. According to a recent study, some carbon dioxide and methane are released during the early spring thaw, suggesting that critical processes are taking place during the Arctic winter.
From NSF, March 14, 2017 -- Little chance this shoreline can withstand accelerating rate of sea level rise, scientists say
Without major efforts to rebuild Louisiana's wetlands, which serve as bulwarks against waves and rising seas, the state's coast has little chance of withstanding the accelerating rate of sea level rise, a new study concludes.
From EARTH Magazine, January 31, 2017 -- Do you know the earthquake risk in your neighborhood? If not, that information is now available in the palm of your hand. Founded by two former U.S. Geological Survey (USGS) employees, Temblor is a free app that allows people to view interactive seismic hazard maps on their smartphones, tablets or computers. It also teaches U.S. homeowners to factor earthquake and landslide risk into their financial decisions, like where to live and what insurance to buy.
From EARTH Magazine, January 25, 2017 -- It makes for a dramatic narrative: Roughly 252 million years ago, a mass extinction event killed up to 96 percent of marine life, earning an infamous name in the geologic record, "the Great Dying." However, a new study suggests that this cataclysmic event has been overestimated.
January 22, 2017 -- IRIS does an excellent job collecting and preparing resources we can use in our classrooms on recent, significant earthquakes. Check out their PowerPoint, visualizations and animations on a magnitude 7.9 earthquake that occurred 40 kilometers (24 miles) west of the town of Panguna, at an intermediate depth (136 km, 84.5 miles) beneath the island of Bougainville, Papua New Guinea.

From AGI, January 19, 2017 -- In April and May 2015, a bloom of toxic algae spanned more than a thousand miles of Pacific coastline, from Santa Barbara, Calif., to British Columbia. Marine organisms were poisoned throughout the food web, disrupting coastal ecosystems and economies for months. Similar events are expected to become more frequent as the oceans and atmosphere adjust to a warming climate.
