Opinion
by shaun gohoAs the United States experiences a glut of natural gas, a host of facilities are being proposed that would convert gas to a liquid and export it. But before embracing a gas export boom, the nation should carefully weigh the implications for both the economy and the environment.

by rebecca kesslerAcross the U.S. Midwest, homeowners are restoring their yards and former farmland to the native prairie that existed in pre-settlement days. The benefits can be substantial — maintenance that uses less water and no fertilizer, and an ecosystem that supports wildflowers and wildlife.

by adam welzThe killing of rhinoceroses has escalated dramatically, especially in South Africa, which is home to 75 percent of the world’s rhino population. The slaughter is being orchestrated by brazen, highly organized gangs that smuggle the rhinos' horns to black markets in China and Southeast Asia.

by fred pearceNo broad-based international agreement on sharing rivers currently exists, even though much of the world depends on water from rivers that flow through more than one nation. But that may be about to change, as two separate global river treaties are close to being approved.

Interview: What’s Damaging U.S.
Salt Marshes and Why It Matters
For centuries, salt marshes along the U.S. coast have been disappearing, with some experts estimating that 70 percent have been lost to development, rising seas,

and other threats. One factor scientists always thought marshes could withstand was nutrient enrichment, such as the flow of nitrogen and phosphorus from fertilizers and septic systems. But a nine-year study led by Marine Biological Laboratory scientist Linda Deegan shows that an over abundance of nutrients may be contributing to the demise of these salt marshes. In a
Yale Environment 360 interview, Deegan describes the study's implications and the vital services that would be lost if marshes disappear, from nourishing marine species to providing a barrier for coastal communities during storms such as Hurricane Sandy.
Read the interviewThe last-minute tax deal brokered by U.S. lawmakers to avert the so-called “fiscal cliff” included a one-year extension of the wind energy tax credit, a subsidy that industry officials say is critical for the growth of the wind energy sector. The bill, which now awaits President Obama’s signature, preserves the 2.2-cents-per-kilowatt-hour credit
for all wind energy projects that begin construction in 2013, allowing projects that are not completed until 2014 to qualify, as well. While the wind energy sector achieved record growth in 2012 — accounting for 44 percent of all new electricity generating capacity in the U.S.
— industry leaders say the possible expiration of the tax credit forced some turbine manufacturers to idle factories and lay off workers during the latter half of 2012. The lack of a long-term federal policy
has created “a ‘boom-bust’ cycle” in the wind energy sector for more than a decade, according to the American Wind Energy Association (AWEA), a trade organization.
Researchers at the University of California, San Diego have developed
a network of smartphone-based air pollution monitors that allow individuals to track

pollution levels in real time and feed a central database of air quality trends citywide throughout the day. The so-called CitySense devices are equipped with sensors that measure ozone, nitrogen dioxide, and carbon monoxide, and a digital app that illustrates the color-coded results based on the U.S. Environmental Protection Agency’s air quality ratings. During a four-week test, in which the phones were distributed to 30 volunteers, the system showed hotspots of elevated pollution that shifted over the course of the day. Ultimately, the developers hope to deploy hundreds of devices in order to generate a public database on air quality levels. “We want more data and better data, which we can provide to the public,” said William Griswold, a computer science professor at UC San Diego. “We are making the invisible visible.”
Interview: Creating Clouds in a Lab
To Better Forecast Climate Change

climate change. Leading that study is British physicist Jasper Kirkby, who oversees complex experiments in a large steel chamber that are designed to help resolve one of the biggest uncertainties of climate change — how clouds form and what role they play in regulating Earth’s temperature. In an interview with
Yale Environment 360, Kirkby talks about the role that cosmic rays — charged particles that hit the Earth from outer space — may play in cloud formation, the pitfalls of geoengineering the planet by trying to mimic the formation of clouds, and why his experiments could help clear up uncertainties about climate change. “We’ve got to reduce that uncertainty if we’re to really sharpen our understanding for future climate projections,” says Kirkby.

Bill McKibben — author, climate activist, and founder of 350.org — is in the midst of a 21-city “Do the Math” tour to build grassroots support for combating climate change.
The target of the campaign is the fossil fuel industry, and McKibben and 350.org are calling for universities, colleges, and governments to divest themselves of oil and coal company assets.
Yale Environment 360 caught up with McKibben by email in Boston recently and asked him five questions about his tour.

The
Consortium for the Barcode of Life (CBOL), a global initiative assembling the “
DNA barcodes” of the world’s endangered species, received $3 million from Google this month to create an online database organizers hope will emerge as a critical tool in the enforcement of international wildlife protection laws. Since it was formed in 2004, the consortium’s 200 participating organizations have collected genetic information for more than 100,000 species. With tens of thousands of species currently in danger of extinction, project organizers hope the database will provide a quick and inexpensive way to identify species, including many that are regularly smuggled through airports. In some cases, law enforcement officials would be able to send a small tissue sample to a laboratory for identification rather than requiring an expert to identify the species.
