National and local conservation groups today condemned a decision by the U.S. Forest Service to continue pressing to open national forest roadless areas in Colorado to coal mining.

In a notice filed today, the Forest Service announced it would move forward by issuing a draft environmental impact statement on the proposal to pave the way for mining. The proposal would reopen a loophole in the “roadless rule” for national forests in Colorado to enable Arch Coal — the nation’s second largest coal company — to scrape roads and well pads on nearly 20,000 acres of otherwise-protected, publicly owned national forest and wildlife habitat in Colorado’s North Fork Valley.

Faced with a raw materials scarcity due to climate change, food and drink giants have turned to a sustainable management in order to protect the environment and ensure their future viability. The global population is expected to rise from 7.3 billion today to 9.7 billion in 2050, according to UN projections. As a consequence, according to a survey published in July by FoodDrinkEurope, this will require a 60% increase in food supplies globally, as well as a 30% rise in global demand for water for agriculture.

Winter storms can blanket Iceland almost entirely with snow. The relative warmth of summer and fall, however, exposes a spectacular, varied landscape. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this natural-color view of the Nordic island nation on November 9, 2015.

“The visible snow cover is typical for this time of the year, compared to conditions during the past 15-20 years,” said Thorsteinn Thorsteinsson, a glaciologist at the Icelandic Meteorologial Office. He noted, however, that compared to the reference period of 1961-1990, snow cover is “almost certainly” less than average in the highland and mountain regions above 400 meters in elevation.

The melting of seasonal snow cover accentuates the boundaries of Iceland’s permanent ice caps. The ice caps appear smooth and rounded in contrast with the snow-covered interior plateau or the snow-capped ridges along the glacier-carved coastline.

It’s the trick question that has left many of us stumped: from the earliest stages of manufacture to the years driving on the road until they are sent to the junkyard, are conventional automobiles or electric cars cleaner for the environment? While acknowledging that electric vehicles (EVs) emit no emissions when running on our streets and highways, many have assumed that those pesky rare earth metals in their massive batteries and the emissions associated with producing the power canceled out any environmental benefits that their drivers enjoyed. According to the Union of Concerned Scientists (UCS), a two-year study has provided the answer.

More sex may not always make you happier, according to new research published by the Society for Personality and Social Psychology. 

"Although more frequent sex is associated with greater happiness, this link was no longer significant at a frequency of more than once a week," lead researcher Amy Muise said. "Our findings suggest that it's important to maintain an intimate connection with your partner, but you don't need to have sex everyday as long as you're maintaining that connection."

Some previous studies, and a plethora of articles and self-help books, have claimed that more sex equals more happiness. But this study, based on surveys of more than 30,000 Americans collected over four decades, is the first to find that association is not there after couples report having sex more than once a week on average. The study was not designed to identify the causal process, so does not tell us whether having sex up to once a week makes couples happier, or being in a happy relationship causes people to have more frequent sex (up to once a week).

A new study by scientists in the UK and France has found that Antarctic ice sheet collapse will have serious consequences for sea level rise over the next two hundred years, though not as much as some have suggested.

This study, published this week in the journal Nature, uses an ice-sheet model to predict the consequences of unstable retreat of the ice, which recent studies suggest has begun in West Antarctica.

An international team of researchers, including a scientist from British Antarctic Survey (BAS), predict that the contribution is most likely to be 10 cm of sea-level rise this century under a mid to high climate scenario, but is extremely unlikely to be higher than 30 cm. When combined with other contributions, that’s a significant challenge for adapting to future sea level rise. But it’s also far lower than some previous estimates, which were as high as one metre from Antarctica alone.
