Amid tensions between the U.S. and China, one issue has emerged on which the two nations are finding common ground: climate change. Their recent commitments on controlling emissions have created momentum that could help international climate talks in Paris in December.

Rapidly rising temperatures, changes in precipitation, and increased lightning strikes are leading to ever-larger wildfires in the northern forests of Alaska, Canada, and Siberia, with potentially severe ecological consequences.

The concept of the "solar suburb" includes a solar panel on every roof, an electric vehicle in every garage, ultra-efficient home batteries to store excess energy, and the easy transfer of electricity among house, car, and grid. But will the technological pieces fall in place to make this dream a reality?

The first runner-up in the 2015 Yale Environment 360 Video Contest captures stunning images of the abundant sockeye salmon runs in Bristol Bay, Alaska, and tells the story of a 70-year-old project that has been studying the millions of salmon that annually pour into the region’s rivers to spawn.

The winning entry in the 2015 Yale Environment 360 Video Contest explores the competing economic interests and sharply divergent worldviews that emerge over plans to erect wind turbines on a scenic ridgeline in Maine. Videographer Roger Smith captures both sides of a debate that divides a rural New England community.

Is it 150 species a day or 24 a day or far less than that? Prominent scientists cite dramatically different numbers when estimating the rate at which species are going extinct. Why is that?

With the world’s coral reefs increasingly threatened by warmer and more acidic seas, scientists are selectively breeding corals to create species with the best chance to survive in the coming century and beyond. Are genetically modified corals next?

Scientists are concerned that officials waited too long to order a ban on U.S. Pacific sardine fishing that goes into effect July 1. The dire state of the sardine population is a cautionary tale about overharvesting these and other forage fish that are a critical part of the marine food web.

As the U.S. and Russia take the first steps to drill for oil and gas in the Arctic Ocean, experts say the harsh climate, icy seas, and lack of infrastructure means a sizeable oil spill would be very difficult to clean up and could cause extensive environmental damage.

After being decimated by disease, pollution, and overharvesting, the Chesapeake Bay’s renowned oysters are thriving once again, thanks largely to a selectively bred oyster that grows rapidly and is more resistant to pathogens. 

The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans’ heat-buffering ability may be weakening.

For decades, the slaughter of sharks sought after for their fins and meat has been staggering. But bans on finning and new attitudes in Asia toward eating shark fin soup are leading to optimism about the future for these iconic ocean predators.

Decades of communist rule and a U.S. embargo have stifled coastal development in Cuba, which has had the beneficial effect of leaving many of the country’s coral reefs intact. In this gallery, photographer Robert Wintner documents the exquisite beauty and biodiversity of Cuba’s coral reef ecosystems.

It’s not just the potential for a catastrophic spill that makes President Obama’s proposal to open Atlantic Ocean waters to oil exploration such a bad idea. What’s worse is the cumulative impact on coastal ecosystems that an active oil industry would bring.

The good news is the world’s oceans have not experienced the extinctions that have occurred on land. But as ecologist Douglas McCauley explains in a Yale Environment 360 interview, marine life now face numerous threats even more serious than overfishing.

After years of fitful starts, the Pacific island nation of Kiribati this month banned all commercial fishing inside its huge marine reserve. New satellite transponder technology is now helping ensure that the ban succeeds in keeping out the big fishing fleets.

The limestone caves of Southeast Asia and southwest China are home to scores of species of plants and animals, many of them rare. But a rise in tourism, mining, and other human activities is increasingly placing these biodiverse environments at risk.

Promising new technologies, including more efficient photovoltaic cells that can harvest energy across the light spectrum, have the potential to dramatically increase solar power generation in the next two decades. But major hurdles remain.

Nearly all sea turtle species have been classified as endangered, with precipitous declines in many populations in recent decades. But new protections, particularly in the U.S. and Central America, are demonstrating that dramatic recovery for these remarkable reptiles is possible.

The tsunami that struck Indonesia in 2004 obliterated vast areas of Aceh province. But villagers there are using an innovative microcredit scheme to restore mangrove forests and other coastal ecosystems that will serve as a natural barrier against future killer waves and storms.
