As solar and wind power grow, another renewable energy source with vast potential — the power of tides and waves — continues to lag far behind. But progress is now being made as governments and the private sector step up efforts to bring marine energy into the mainstream.

Scientists are becoming increasingly concerned about the fate of the huge boreal forest that spans from Scandinavia to northern Canada. Unprecedented warming in the region is jeopardizing the future of a critical ecosystem that makes up nearly a third of the earth’s forest cover.

In an interview with Yale Environment 360, the Rev. Lennox Yearwood — a social and environmental activist and the head of the Hip Hop Caucus — explains why it’s vital that the climate and environmental movements become far more diverse.

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.

On ancestral lands, the Fond du Lac band in Minnesota is planting wild rice and restoring wetlands damaged by dams, industry, and logging. Their efforts are part of a growing trend by Native Americans to bring back traditional food sources and heal scarred landscapes.

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.

More than half a century after scientist Rachel Carson warned of the dangers of overusing the pesticide DDT, conservative groups continue to vilify her and blame her for a resurgence of malaria. But DDT is still used in many countries where malaria now rages.

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.

An astonishing 18 percent of the European Union’s land area is protected under a network of preserves known as Natura 2000. Now, at the urging of business interests and farmers, the EU is examining whether regulations on development in these areas should be loosened.

Weaning the U.S. economy off fossil fuels will involve the wide deployment of utility-scale solar power. But for that to happen, the environmental community must resolve its conflict between clean energy advocates and those who regard solar farms as blights on the landscape.

A Yale Environment 360 video goes onto the front lines with Colorado fire crews who have watched as massive, months-long wildfires have become a regular occurrence in their state.

Many hydroelectric dams produce modest amounts of power yet do enormous damage to rivers and fish populations. Why not take down these aging structures, build solar farms in the drained reservoirs, and restore the natural ecology of the rivers?

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?

The fossil fuel divestment campaign has so far persuaded only a handful of universities and investment funds to change their policies. But if the movement can help shift public opinion about climate change, its organizers say, it will have achieved its primary goal.

Filmmaker Thomas Lennon says camera drones have opened up dramatic new possibilities for seeing the natural world and inspiring the public to protect it. In an e360 interview, he talks about how his drone video from the Delaware River illustrates the potential of this new technology.

Marijuana growers are ravaging forests in northern California to produce their lucrative crop. In a Yale Environment 360 interview, biologist Mary Power talks about the massive ecological footprint of marijuana growing and why nationwide legalization could help alleviate it.

As climate change puts ecosystems and species at risk, conservationists are turning to a new approach: preserving those landscapes that are most likely to endure as the world warms.

East Caicos is a tropical jewel — the largest uninhabitated island in the Caribbean and home to rare birds and pristine turtle-nesting beaches. But plans for a giant port for cruise and cargo ships could change it forever.
