The Peace-Athabasca Delta, one of the world’s largest freshwater deltas, is facing major change as rising temperatures, a prolonged drought, and water withdrawals for Alberta’s tar sands industry threaten to increasingly dry out this vast expanse of waterways and wetlands.

Marine phytoplankton are vital in absorbing ever-increasing amounts of CO2 from the atmosphere. In a Yale Environment 360 interview, researcher Tracy Villareal explains how he is using remotely operated robots to better understand how this process mitigates climate change.

China is engaged in a push to build hydroelectric dams on a scale unprecedented in human history. While being touted for producing lower-emission electricity, these massive dam projects are wreaking havoc on river systems across China and Southeast Asia.

One year after Hurricane Sandy devastated parts of the U.S. East Coast, the government is spending billions to replenish beaches that will only be swallowed again by rising seas and future storms. It’s time to develop coastal policies that take into account new climate realities.

As Bangladesh makes a controversial turn to coal to produce electricity, the construction of a large coal-fired power plant is threatening the fragile ecosystem of the Sundarbans, the world’s largest mangrove forest.

The U.N. climate panel concluded last month that carbon emissions should be capped at a trillion tons, a total the world is rapidly approaching. Now comes the hard part: How will we decide how the remaining emissions are apportioned?

Traveling throughout China, from the Tibetan Plateau to the lush subtropical forests in the south, a photojournalist documents the vast scope of the country's environmental challenges.

As eel populations plummet worldwide, Japanese scientists are racing to solve a major challenge for aquaculture — how to replicate the life cycle of eels in captivity and commercially produce a fish that is a prized delicacy on Asian dinner tables.

Yale Environment 360 asked some leading climate scientists to discuss what they consider to be the most noteworthy or surprising findings in the recently released report of the Intergovernmental Panel on Climate Change’s working group on the physical science of a warming world.

Still reeling from recent financial crises, Iceland is hoping to use its bountiful sources of geothermal and hydroelectric energy to help boost its economy. Among the country’s more ambitious plans is an undersea cable to carry renewably generated electricity to the U.K.

Some scientists are saying the latest report from the Intergovernmental Panel on Climate Change is overly conservative and fails to mention some of the most worrisome possible scenarios. The panel, they contend, is no longer fulfilling its mission of informing policy makers of the risks of global warming.

After years of delays and legal battles, several offshore wind projects seem poised to be launched off the U.S. East Coast. But the lack of stable government incentives and tax credits may continue to hobble an industry that already has a strong foothold in Europe.

Australia is the world’s second-largest exporter of coal, thanks to huge markets in China, Japan, and other Asian countries. Environmentalists have been struggling to scale back the nation’s coal boom, but the recent election of a conservative prime minister may keep coal on top.

To overcome polarization on the issue of climate change, Yale professor Dan Kahan says in an interview with e360, scientists and the media need to frame the science in ways that will resonate with the public. A message that makes people feel threatened, he says, simply will not be effective.

Researchers at a lab at Oregon State University are using zebrafish to assess the impacts of multiple chemical exposures. Their findings could help lead to a better understanding of how chemicals in the environment and in consumer products affect human health.

Anand Shah runs a company that is using solar-powered “water ATMs” to bring clean water to remote villages in India. In an e360 interview, Shah talks about how his company is using a high-tech approach to address one of India’s most intractable public health issues.

Faced with the prospect of a dwindling customer base, some U.S. power companies are seeking to end public subsidies and other incentives for rooftop solar. In Arizona, the issue has sparked a heated public relations battle that could help determine the future of solar in the United States.

Transformed by British sailors in the 19th century, Ascension Island in the South Atlantic has a unique tropical forest consisting almost entirely of alien species. Scientists say that what has happened there challenges some basic assumptions about ecosystems and evolution.

Every U.S. president since Ronald Reagan has backed programs to develop alternative transportation fuels. But there are better ways to foster energy independence and reduce greenhouse gas emissions than using subsidies and mandates to promote politically favored fuels.

As evidence mounts that excessive use of light is harming wildlife and adversely affecting human health, new initiatives in France and elsewhere are seeking to turn down the lights that flood an ever-growing part of the planet.
