Forum: How Daring is
Obama's New Climate Plan?

President Obama has unveiled a proposal to combat global warming that would, for the first time, regulate carbon dioxide emissions from all U.S. coal-fired power plants. Yale Environment 360 asked a group of experts to assess the president’s climate strategy.

Forum: Assessing Obama’s
Record on the Environment

When Barack Obama won the presidency in 2008, environmentalists were optimistic that their issues would finally become a priority at the White House. So how is Obama doing? Yale Environment 360 asked a group of environmentalists and energy experts for their verdicts on the president's performance.

Forum: Just How Safe
Is ‘Fracking’ of Natural Gas?


New technologies for freeing natural gas from underground shale formations have led to a hydraulic fracturing boom across the U.S. that is now spreading to other countries. In a Yale Environment 360 forum, eight experts discuss whether “fracking” can be done without serious harm to water and air quality and what environmental safeguards may be needed.

Forum: Is Extreme Weather
Linked to Global Warming?


In the past year, the world has seen a large number of extreme weather events, from the Russian heat wave last summer, to the severe flooding in Pakistan, to the recent tornadoes in the U.S. In a Yale Environment 360 forum, a panel of experts weighs in on whether the wild weather may be tied to increasing global temperatures.

As Copenhagen Talks Near,
What Are Prospects for Success?

For months, hopes that a climate treaty would be signed at the upcoming Copenhagen conference have been raised, then dashed, then raised again. Now, with prospects waning that a binding accord on reducing greenhouse gas emissions can be reached this year, ten environmental leaders and climate experts outline for Yale Environment 360 what they believe can still be accomplished at Copenhagen.

The Waxman-Markey Bill:
A Good Start or a Non-Starter?

As carbon cap-and-trade legislation works it way through Congress, the environmental community is intensely debating whether the Waxman-Markey bill is the best possible compromise or a fatally flawed initiative. Yale Environment 360 asked 11 prominent people in the environmental and energy fields for their views on this controversial legislation.

Putting a Price on Carbon:
An Emissions Cap or a Tax?

The days of freely dumping greenhouse gases into the atmosphere are coming to an end, but how best to price carbon emissions remains in dispute. As the U.S. Congress debates the issue, Yale Environment 360 asked eight experts to discuss the merits of a cap-and-trade system versus a carbon tax.

In East Coast Marshes, Goats
Take On a Notorious Invader


Land managers in the eastern U.S. and Canada have spent countless man-hours and millions of dollars trying to tame a pernicious, invasive reed known as Phragmites australis. Toxic herbicides, controlled burns, and even bulldozers have been the go-to solutions to the problem. But recent research out of Duke University suggests another, less aggressive fix: goats. The approach is finding practical applications, including in New York City, where officials deployed a herd of goats at Staten Island’s Freshkills Park.

30 Oct 2014: China Is Top Developing Nation for Clean Energy Investment, Analysis Finds

China is the most attractive among developing nations for low-carbon investment and deployment, according to an analysis by the Climatescope project, a partnership among various international development agencies and Bloomberg New Energy Finance. China received top marks because it is the largest manufacturer of wind and solar equipment in the world, has the largest demand market for wind and solar energy, and has taken major strides to improve its domestic policy framework score, the analysis said. Brazil ranked second, largely due to the country's aggressive approach to clean energy development and the availability of low-cost capital through its national bank, the report said. South Africa ranked third, and the analysis noted the nation had attracted $10 billion in clean energy investments in 2012 through 2013. The project ranked 55 developing countries on their past, present, and future ability to attract investment for clean energy companies and projects.

 

Interview: A Call for Climate Goals
Other Than Two Degrees Celsius

When international delegates meet in Paris next year to negotiate a new climate agreement, they'll be aiming to keep the global average temperature from rising more than 2 degrees
“David
David Victor
Celsius above pre-industrial levels, the maximum seen by many for avoiding the worst impacts of climate change. But David Victor, a professor of international relations at University of California San Diego, argued in a recent controversial commentary in Nature that the 2-degree goal is now unattainable and should be replaced by more meaningful goals. In an interview with Yale Environment 360, Victor explains why he believes the 2-degree threshold has failed to position policy makers to take serious action on climate change and outlines the "basket of indicators" that he and his co-author are suggesting be used instead.

29 Oct 2014: Weather and Climate Key in Weights of Penguin Chicks, Researchers Say

Local weather and large-scale climate trends have the largest impact on the weights of Adélie penguin chicks

An adult Adélie penguin feeds its chick.
— not food availability — according to researchers at the University of Delaware. Adélie penguins are native to the West Antarctic Peninsula, and their habitat is warming faster than most other parts of the planet. Looking at records dating back to 1987, scientists found that year-to-year changes in local weather — including wind speed, temperature, rain, and humidity — could cause chicks’ weights at the time they leave their nests to fluctuate by up to 7 ounces. That’s often the difference between a surviving and non-surviving chick, the researchers say. Biologists previously thought that food sources and parenting played the largest role in chicks’ health, but these findings suggest that exposure to elements is more important. The study "calls into question what happens to an ecosystem when you change climate quickly," principal investigator Matthew Oliver said.

 

E360 Video Winner: A Legacy of
Toxic Pollution in Southern Waters


“A Red Dirt Town,” which placed second in the Yale Environment 360 Video Contest, examines the legacy of pollution in Anniston, Alabama, the former home of a Monsanto chemical factory. The video, produced by Spenser Gabin, tells the story of how PCBs from the Monsanto plant contaminated the town’s waterways and taint the fish that are popular with local anglers.

28 Oct 2014: Scientists Find Seafloor Fallout Plume of Oil from Deepwater Horizon Spill

Researchers say they have found a large fallout plume of oil on the seafloor from the 2010 Deepwater Horizon

Deepwater Horizon oil at the surface of the ocean
disaster in the Gulf of Mexico. According to a report in the Proceedings of the National Academy of Sciences, a portion of the 2 million barrels of oil thought to be trapped in the deep sea after the spill appears to have settled across a 1,250-square-mile patch of the seafloor centered around the Macondo Well, which discharged an estimated 5 million barrels of oil in the nearly three months between its blowout in April and eventual capping in July. The oil is concentrated in the top half-inch of the seafloor, and mostly distributed in patchy deposits to the southwest of the well, the study found. These deposits account for between 4 and 31 percent of the Macondo oil sequestered in the deep ocean, researchers estimate. The rest has likely been deposited outside this area, they say, but has evaded detection so far because of its patchiness.
