Two provocative ways to see long-term changes on earth are currently being promoted in honor of Earth Week. A Web site by NASA, and an app from HarperCollins, both show striking side-by-side satellite images of locations that have changed dramatically over time spans of up to 30 years or more...
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...
Most people are aware that reducing carbon emissions could help the planet.

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.
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...
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.
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...
