Though shale gas extraction with the use of hydraulic fracturing has been underway in the U.S. for about a decade, peer-reviewed literature looking at its impacts has only begun to be published. Some of the articles that were among the first published on the environmental impacts, and remain among the most talked about, are described here.
Previous research on hydraulic fracturing has indicated possible contamination of water wells by methane. A new research article attempts to model potential contamination pathways to aquifers from Marcellus shale gas beds.
Drinking water wells are only 60 to 90 meters below the surface, while the Marcellus Shale is at depths of 1,200 to 2,500 meters. Still, new research suggests that, because of the hydrology of northeastern Pennsylvania, hydraulic fracturing poses a risk to these shallow drinking water resources.
A new study calculates the total water usage for shale-gas production in Texas. While the total water usage doesn't overwhelm state resources currently, the variability in local conditions over time will call for more careful consideration of water resources in the future.
It is often assumed that global warming will make mountain trees climb uphill. A new long-view study shows that this is not always the case, meaning that managers must take heed when planning the future of their forests.
Many conservationists and land planners look to property tax policy to encourage private landowners to keep their land undeveloped. While property tax can hold back the conversion of rural land to some extent, its impact is limited.
Jellyfish blooms are an increasingly frequent problem in many parts of the world. While it has long been understood that these blooms deprive fish and other species of food, new research sheds light on how they disrupt the ecosystem in ways that reduce the productivity of the oceans.
Local leaders must prepare for sea-level rise and coastal disaster management. Besides property damage, issues of social justice will arise because minorities, the poor, and the most vulnerable people are at greater risk than others.
In the summer of 1993, over 12,000 people flocked to the otherwise remote Clayoquot Sound to protest the logging of old growth forest on Meares Island, British Columbia. This precipitated changes in the public participation process that are still evolving twenty years later.
Almost 30% of New York State's electricity demand can be met by wind and solar energy, and having both forms of renewable energy operating at the same time can significantly reduce the problem of intermittency.
