When people think of dangerous faults in America, the the San Andreas probably comes to mind first. But another potentially greater threat lurks in the East Bay region of Northern California, just a stone's throw from San Francisco and the tech hub of Silicon Valley: the Hayward Fault. In the June issue, EARTH Magazine guest author Steven Newton lays out just what is at risk, and what to expect when an earthquake strikes on what may be the most dangerous fault in America.

For many years, scientists have pondered if the Vikings' diaspora to Greenland was made easier by the warmer temperatures of the Medieval Warm Period. Climate data extracted from shells had indicated that this warm period extended to Greenland, but new research looking at glacial movements and using isotope data from terminal moraines suggests this may not necessarily be so.

For years, scientists have used mineral, sediment and ice layers, deposited intermittently throughout geologic time, to track the global climate record. These can come from caves, lakes, the oceans and ice sheets. But over the course of the last decade a new method has been developed that presents an opportunity for geoscientists to assess global climate history in almost any arid landscape.

For more than 40 years, AGI's Data Sheets have been a critical tool for the geoscientist in the field, the lab, and the classroom. For decades its bright orange cover and three-ring binding were distinctive in the geoscience community. The book evolved into its current, full-color and spiral bound format with the 2005 debut of the fourth edition.

In celebration of Earth Science Week 2016, the American Geosciences Institute (AGI) is sponsoring four contests honoring this year's theme, "Our Shared Geoheritage." This year's competitions will feature the traditional photography contest, visual arts contest, and essay contest -- as well as a new video contest.

EARTH Magazine plunges into the depths of the ocean with scientists seeking whether Earth's climate and sea-level history are intrinsically linked with tectonics at mid-ocean ridges.

Between Utah and Colorado, there is a geographical diamond in which lies a rich collection of fossils and dinosaur footprints recording the history of when dinosaurs inhabited this region. All major ages of dinosaur life are recorded here, and for more than a hundred years, paleontologists have busily been debating which dinosaurs existed based on bones and abundant dinosaur tracks, the latter of which provide clues that allow geoscientists to interpret dinosaur daily life.

The Deep Carbon Observatory Diversity Grants program is made possible through support from Alfred P. Sloan Foundation, and is designed to bolster participation of traditionally underrepresented geoscientists in the United States within the Deep Carbon Observatory community. The Deep Carbon Observatory is a global research program to transform our understanding of carbon in Earth. DCO is a community of scientists, from biologists to physicists, geoscientists to chemists, and others whose work crosses these disciplinary lines, forging a new, integrative field of deep carbon science.

Leading up to Earth Science Week 2016, the American Geosciences Institute (AGI) is pleased to invite teams of educators and students to enter its new "One Shared Place" contest. Each team will submit a 30- to 90-second original video informing viewers about an outdoor place that is special in terms of geoheritage (natural features, settings, and resources formed over vast periods) and geoscience (the study of Earth systems).

This issue, EARTH Magazine explores the world's top weather-related killer: exposure to extreme heat. Humans' response to extreme heat leads to heat stress, an illness related to the body's inability to cool itself. Humidity plays a crucial role, because as humidity increases, the ability of sweat to evaporate and cool the body decreases.
