The record-breaking drought in California is not chiefly the result of low precipitation. Three factors — rising temperatures, groundwater depletion, and a shrinking Colorado River — mean the most populous U.S. state will face decades of water shortages and must adapt.

No nation has as high a penetration of residential solar as Australia, with one in five homes now powered by the sun. And while the government has slashed incentives, solar energy continues to grow, thanks to a steep drop in the cost of PV panels and the country’s abundant sunshine.

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.

Officials in the Florida Keys are seeking to use a GM mosquito that could help prevent a recurrence of dengue fever there. But fears among some residents — which scientists say are unfounded — are slowing the release of mosquitoes whose offspring are genetically programmed to die.

The Sierra Club has chosen Aaron Mair as its president, the first African-American to lead the largest U.S. environmental organization. In an interview with Yale Environment 360, he talks about the lack of diversity in the environmental movement and what can be done to change that.

Since pre-Islamic times, Oman’s water systems known as aflaj have brought water from the mountains and made the desert bloom. But now, unregulated pumping of groundwater is depleting aquifers and causing the long-reliable channels to run dry.

Thanks to favorable geography, innovative government policies, and businesses that see the benefits of clean energy investments, California is closing in on its goal of generating a third of its electricity from renewables by 2020.

The Cross River gorilla population in equatorial Africa has been pushed to the brink of extinction. In a Yale Environment 360 interview, a Nigerian scientist working to save the gorillas describes how local villagers are vital to protecting these apes.

In the second in an e360 video series, filmmaker Karim Chrobog travels to Seoul, South Korea, which has implemented a high-tech initiative that has dramatically reduced its food waste. Seoul’s efforts could serve as a model for how a major city can recycle discarded food and keep it out of landfills.

An e360 video looks at the staggering amount of food wasted in the U.S. Filmmaker Karim Chrobog focuses on efforts in Washington, D.C., to see that food ends up with those who need it rather than dumped in landfills. First in a series.

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. 

Scientists have theorized that tropical birds in mountainous regions will move uphill as the climate warms. But new research in the Peruvian Andes suggests that the birds will stay put and face a new threat — predator snakes that will climb into their territory to escape the heat.

A potential answer to California’s severe water shortages is groundwater banking, which involves creating incentives for municipalities, farmers, and other water users to percolate water down into sub-surface aquifers for later use.

Work has already begun on a $50 billion inter-ocean canal in Nicaragua that would cut through nature reserves and bring massive dredging and major ship traffic to Central America’s largest lake. Scientists and conservationists are warning that the project is an environmental disaster in the making.

Seven years ago, British Columbia became the first jurisdiction in North America to adopt an economy-wide carbon tax. In a Yale Environment 360 interview, economics expert Stewart Elgie explains how the tax helped cut the province’s fossil fuel use without hurting its economy.

Offshore wind farms have been proliferating in the North Sea, with more huge projects planned. But conservationists are concerned this clean energy source could threaten seabird colonies that now thrive in the sea’s shallow waters.

Oklahoma officials this week said oil and gas activity was the likely cause of the stunning increase in earthquakes in the state. In an interview with Yale Environment 360, Oklahoma geologist Todd Halihan talks about what has caused this growing problem and what can be done about it.

On eBay and elsewhere on the Internet, illegal wildlife and wildlife parts — from elephant ivory to tiger skins to monkey and crocodile skulls — are being sold. Bringing an end to this illicit activity is proving to be a daunting challenge.

As a Tibetan Buddhist leader, the Karmapa is promoting green practices in monasteries in the Himalayan region. In an interview with Yale Environment 360, he talks about how the world needs both religion and science in tackling the “environmental emergency” of climate change.

In Germany, the Netherlands, Denmark and other countries, European governments are beginning to push farmers, industry, and municipalities to cut back on fertilizers and other sources of nitrogen that are causing serious environmental harm.

At Kenya’s Ol Pejeta wildlife sanctuary, home to some of the world’s most critically endangered rhinoceros species, Belgian Malinois tracking and attack dogs are being deployed in the battle against rhino poachers.
