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.

With the dismantling of two dams on Washington state’s Elwha River, the world’s largest dam removal project is almost complete. Now, in one of the most extensive U.S. ecological restorations ever attempted, efforts are underway to revive one of the Pacific Northwest’s great salmon rivers.

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.

With advances in genetic sequencing technology, scientists are now able to readily identify the microbes living in and around the roots of trees. This information is proving to have important implications for everything from tropical forest restoration to climate change planning.

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.

The pangolin does not make headlines the way elephants or rhinos do. But the survival of this uncharismatic, armor-plated animal is being threatened by a gruesome trade in its meat and its scales.

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.

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.

Increasingly common in Europe, municipal “waste-to-energy” incinerators are being touted as a green trash-disposal alternative. But critics contend that these large-scale incinerators tend to discourage recycling and lead to greater waste.

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.

Climate scientists and humanitarian relief workers need to collaborate far more closely to prepare for a future of increased extreme weather events. In an interview with Yale Environment 360, Harvard University public health expert Jennifer Leaning analyzes the results of a meeting between these two very different factions.

African countries and private game reserves are engaging in an increasingly sophisticated arms race against poachers, yet the slaughter of elephants and rhinos continues. Some experts argue that the battle must be joined on a far wider front that targets demand in Asia and judicial dysfunction in Africa.

A move by New York City to begin collecting food scraps and other organic waste is just the latest example of expanding efforts by municipalities worldwide to recycle large quantities of unused food and slash the amount of material sent to landfills.
