EARTH: Crippling Heat Stress Projected by Midcentury in Densely Populated Regions

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.

EARTH: Hidden Double Earthquakes Spells Trouble for Tsunami Warning Systems

A magnitude-7.1 earthquake struck Chile on Jan. 2, 2011, or so scientists thought. Now, with increasing sensor sensitivity and advances in the quantitative analysis of earthquakes, scientists have revealed that this quake was actually a doublet. This meant that instead of just one massive quake, two similarly large earthquakes struck very near to one another within seconds. The closely spaced doublet was missed by global monitoring networks during the initial aftermath of the quake, and, as EARTH Magazine explores, it presents a major challenge to earthquake and tsunami warning systems. Experts agree this is a challenge that must be brought to the forefront of seismic research.

EARTH: Studies Re-examine How Major Copper Deposits Form

Humans depend on copper for everything from electrical wiring to water pipes. To meet demand, the metal has been largely mined from Porphyry Copper Deposits (PCDs). For decades, scientists generally agreed upon the geological processes behind PCD formation; now EARTH Magazine examines two new studies that suggest alternatives to these long-held understandings.

EARTH: Science Illustrators - Making the Invisible Visible

From the tiny microcosms of atomic theory and futuristic colonies on Mars to dinosaurs walking the Earth, science illustrators translate scientific findings and theories into something lifelike, accurate and aesthetically pleasing. The July cover story from EARTH Magazine, "Science Illustrators: Making the Invisible Visible," takes readers on a behind-the-scenes of how illustrators transform a scientific concept into an informed work of art.

EARTH: Beyond the Bomb - The World's Nuclear Watchdog Expands Its Science

With hundreds of seismic, infrasound, hydroacoustic and radionuclide-detecting stations operating continuously around the world, CTBTO scientists - and, increasingly, researchers outside the organization - are realizing the potential of all the data collected. CTBTO data have been used to understand major natural events such as the 2013 Chelyabinsk meteor and the 2011 Japanese earthquake, tsunami and eventual nuclear disaster. And in the future, it may contribute to improved volcano monitoring and understanding of atmospheric processes.
