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. In the February issue of EARTH Magazine, read how scientists are working to better understand the 2015 Pacific bloom, hoping to apply lessons learned in responding to future events.

The latest research suggests humans first arrived in the Americas as early as 16,000 years ago, but using which path - along the Pacific coast, through an inland ice-free corridor, or from the East along the Atlantic coast - remains controversial. Archaeologists and geologists are working to try to answer the question of how and when the first Americans arrived. In the January issue of EARTH Magazine, their work is showcased, reexamining the origins of our shared geoheritage in light of new evidence.

The American Geosciences Institute (AGI) is pleased to announce that the theme of Earth Science Week 2017 is "Earth and Human Activity." This year's event, the 20th annual Earth Science Week celebration, promotes awareness of what geoscience tells us about human interaction with the planet's natural systems and processes.

Slow-moving landslides, while not as dramatic as their faster-moving counterparts, can damage infrastructure and cause headaches for the communities they affect. Slow-moving slides are generally associated with rainfall or snowmelt, but a new study in Japan has shown that some of these slides may occur when a certain kind of clay is exposed to cold temperatures. In the January issue of EARTH Magazine, the link between ground temperature and slow slides is explored, including implications for the science of predicting similar landslides around the world.

On Nov. 13, 1985, the eruption of the Nevado del Ruiz volcano in Colombia killed more than 23,000 people. Geoscientists at the U.S. Geological Survey’s Cascades Volcano Observatory in Vancouver, Wash., moved to action. Having studied the warning signs and responded to the eruption of Mount St. Helens five years earlier, they knew from experience that the Nevado del Ruiz disaster could have been prevented. Their advocacy paved the way for the formation of the Volcano Disaster Assistance Program (VDAP) in 1986. VDAP is the world’s first and only international volcano response team. In the January issue of EARTH Magazine, VDAP’s growth and evolution over 30 years are chronicled, highlighting the team’s past successes and goals for the future.

The American Geosciences Institute is pleased to announce the latest award recipients of the Deep Carbon Observatory (DCO) Diversity Grants. This was the final round of awards for the current two-year project supported by the Alfred P. Sloan Foundation. During the course of this project, AGI supported a total of 14 traditionally underrepresented geoscientists to participate in DCO-related research, events, and field experiences. A review of the project and its findings was presented at the 2016 Geological Society of America Annual Meeting.
