Scientists speak out about risks, studies and testing
April 22 marks the 42 nd annual Earth Day observance. In recent years, the week running up to Earth Day has become increasingly filled with a riotous mix of news that ranges from inspired initiatives to thinly veiled partisanship and shameless exploitation...
In her latest comic book, graphic novelist Kate Evans helps readers understand carbon trading schemes and their shortcomings
Most people are aware that reducing carbon emissions could help the planet. But convincing a particular individual to change his or her behavior in ways that emit less carbon—not to mention the behavior of an entire city—can be a monumental challenge.David Gershon, founder of the Empowerment Institute in Woodstock, N.Y., is taking on that challenge, with help from three urban managers who hope their cities can become models for the future.Gershon, who authored the 2006 book and program Low Carbon Diet, has spent 20 years researching how to change community behavior...
Will the unethical release of documents from the controversial Heartland Institute undermine climate science? We ask climate scientist Gavin Schmidt
It's easy to find an online test that will purportedly tell you how happy you are. But how happy are the people of an entire nation? And which nation's people are happiest?That's hard to measure...
VANCOUVER—Resistance to hydraulic fracturing in the U.S. has risen steadily in recent months. Citizens and politicians are worried that fracking deep shales to extract natural gas can contaminate groundwater, trigger earthquakes and release methane, the potent greenhouse gas, into the atmosphere...
Earth's flora is responsible for the glaciers and rivers that have created this planet's distinctive landscape
More than six years after Hurricane Katrina plowed into New Orleans and the Mississippi River delta, a plan has finally emerged to protect the area from future storms.
Female students, and management dreams, are changing the mix
Despite studying science, technology, engineering or math, many students avoid STEM careers. Higher salaries, improved status and apprenticeships would change that. A special online-only addition to February 2012's Graphic Science...
"Fugitive methane" released during shale gas drilling could accelerate climate change
Hurricane Katrina battered New Orleans in 2005 and little has been done since then to improve long-term storm protection for the city and surrounding delta.
The jet stream controls winter weather, but strange forces are controlling the jet stream this season
New York State is the key battleground that will determine the future of fracking in the U.S., and January 11, 2012, is a turning point. The date ends the public comment period on proposed state regulations that will govern the process: drilling into deep Marcellus shales, fracturing the rock with water and chemicals to release natural gas, and disposing of the resulting wastewater that flows back up the well with the gas...
Injecting wastewater deep underground is the prime suspect, potentially widening earthquake worries linked to hydraulic fracturing
Many of us may remember the jaw-dropping images of the May 22, 2011, tornado that tore through Joplin, Mo., killing 158 people and leaving an incredible 14-mile path of destruction.
Russian and U.S. nuclear arsenals dwarf the rest
