At least 70 percent, and as much as 95 percent, of sea ice loss in the Arctic is the result of human activities such as the burning of greenhouse gases, according to a new study.

Grocery Manufacturers Association Long-time Obstructionist of Public Health In case you had any doubt that California’s Prop 37—which would require labeling of food containing genetically-modified organisms (GMOs)—is a significant threat to industry, a top food lobby has now made it perfectly clear.

The Pacific Northwest may be the epicenter of U.S. coffee culture, and now a new study shows the region's elevated caffeine levels don't stop at the shoreline.

On July 26 the U.S. House of Representatives approved the so-called “Red Tape Reduction and Small Business Job Creation Act” (H.R. 4078), a dangerous and irresponsible bill that would halt nearly all significant rulemaking by federal agencies until the nation’s unemployment rate drops to six percent. The bill would derail critical safeguards aimed at cleaning up our air and water, ensuring the safety of our children, protecting our wildlife and increasing the fuel efficiency of our cars and trucks. The bill also contains measures that would unnecessarily gridlock the federal courts, wasting taxpayer resources and interfering with the ability of citizens to receive justice.

The middle of the United States hasn’t seen a drought as destructive as this summer’s since 1956, and the results are no joke: In the plains, corn farmers are looking on as wave after wave of heat punishes their fields. In the west, ranchers searching for grass for their cattle are coming up with nothing more than scorched earth, devastated by wildfires. In the cities, government agencies are trying to figure out how to keep thousands of young trees alive. With the help of a community group, Chicago’s come up with a plan to potentially stave off disaster: by asking the community to crowdsource watering.

Last week there were the pictures of an iceberg twice the size of Manhattan breaking off Greenland's Petermann Glacier.

In North America this summer, drought, fire, and heat are putting climate back in the headlines — if not, yet, in the election-year political debate. At such moments, it’s tempting for anyone who’s been talking about the issue all along to pile on with the “see what we mean?”s and “we told you so”s. But it’s far more important to use the moment to catalyze understanding and action.

A thorough and well reported Bloomberg News story today revealed that several recent academic studies on fracking were ultimately funded by the gas drilling industry itself. These studies had the imprimaturs of respected public universities including Penn State, University of Texas and SUNY-Buffalo and were cited by politicians arguing for policies that are advantageous to the fracking industry. It turns out that the studies were either sponsored by the fracking industry or were prepared by researchers with a long history of producing industry-friendly reports, or both.

Last week, the U.S. Department of Agriculture (USDA) ruled once and for all to allow unrestricted planting of Monsanto’s GMO sugar beets. This announcement puts an end to a long court battle to force the USDA to uphold the law — a battle that some anti-GMO advocates might call Pyrrhic.

One of the most popular trends in sustainable living is to go small: Live in a small house. Drive a small car. Have a small carbon footprint. So it seems contradictory that by going big—really big—energy equipment can become better for the environment.
