More carbon dioxide in the atmosphere also makes the oceans more acidic — and that's bad news for many marine creatures that rely on calcium carbonate shells to survive. But it's not that simple, scientists are discovering: Not all shell-building creatures respond the same way to acidifying seawater.
Is every snowflake truly unique? Physicist Kenneth Libbrecht has made a career out of photographing the variety of snowflake shapes, from familiar six-sided forms to more exotic "bullet rosettes" and "capped columns." EARTH's latest slideshow takes you on a visual tour of these delicate ice crystals.
Ravaged by war, drought and natural hazards such as earthquakes and landslides, Afghanistan’s people face many challenges. Two stories in the most recent issue of EARTH magazine highlight the daunting challenges these scientists dealt with in the past and continue to face.
Since 1939, a progression of deadly earthquakes has been marching westward across Turkey's North Anatolian Fault. All signs point to Istanbul as the next likely target — but Turkey's largest city may be struck by a series of moderate earthquakes, rather than one big event.

Scientists have upgraded the potential earthquake threat to cities including Portland, Ore., Seattle, Wash., and Vancouver, British Columbia in the Pacific Northwest. Although it was once thought that large earthquakes in this region, called the Cascadia Subduction Zone, would more likely happen offshore, they could occur much closer to the coast.
As you would expect, there's been tons of coverage of the earthquake off the coast of Chile and the resulting tsunami in the mainstream media. And yes, some of it has been notoriously poor.
