While we’re a long way behind countries like the UK, there seems to be a growing momentum behind US offshore wind development—suggesting we might finally get serious about the incredible potential for this increasingly competitive technology. The latest such signal is an announcement from the Department of Interior proposing a lease sale for the 122,405-Acre Kitty Hawk Wind Energy Area.

Electric cars that exist today could be widely adopted despite range constraints, replacing about 90 percent of existing cars, and could make a major dent in the nation's carbon emissions, new research indicates.

The study, which found that a wholesale replacement of conventional vehicles with electric ones is possible today and could play a significant role in meeting climate change mitigation goals, was published today in the journal Nature Energy by Jessika Trancik, the Atlantic Richfield Career Development Associate Professor in Energy Studies at MIT's Institute for Data, Systems, and Society (IDSS), along with graduate student Zachary Needell, postdoc James McNerney, and recent graduate Michael Chang SM '15.

Overfishing of large and top predatory fishes on Caribbean coral reefs substantially reduces the amount of nutrients stored and recycled within the ecosystem by fishes, new interdisciplinary research published today in Nature Communications concludes.

The study, by scientists at the University of Washington, the Center for Biological Diversity, the Smithsonian Institution and North Carolina State University, suggests that while avoiding local extinction of fish species is a conservation priority, management actions that preserve large fish groups such as sharks, groupers, snappers and jacks are needed to maintain an adequate flow of nutrients within ecosystems.

Researchers have flown aircraft over an oil and gas field and pinpointed -- with unprecedented precision -- sources of the greenhouse gas methane in real time. The technique led to the detection and immediate repair of two leaks in natural gas pipelines in the Four Corners region of the U.S. Southwest.

The technique led to the detection and immediate repair of two leaks in natural gas pipelines in the Four Corners region of the U.S. Southwest. The approach could inform strategies for meeting new federal limits on methane emissions from the oil and gas industry. Methane emissions have spiked in recent decades along with the boom in natural gas drilling.

A surge in major wildfire events in the U.S. West as a consequence of climate change will expose tens of millions of Americans to high levels of air pollution in the coming decades, according to a new Yale-led study conducted with collaborators from Harvard.

The researchers estimated air pollution from past and projected future wildfires in 561 western counties, and found that by mid-century more than 82 million people will experience "smoke waves," or consecutive days with high air pollution related to fires.

The regions likely to receive the highest exposure to wildfire smoke in the future include northern California, western Oregon, and the Great Plains.
