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.

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.

Yale Environment 360 asked Rajendra K. Pachauri, who has served as IPCC chairman since 2002, five questions about the latest report and about the prospects that the international community will finally take decisive action to address climate change at talks scheduled in Paris in 2015.

24 Apr 2014: Browning of Congo Rainforest
Is Depicted in NASA Satellite Data

Persistent drought has taken a major toll on Africa's Congo rainforest, with large-scale browning intensifying and affecting a growing portion of the forest over the past decade, an analysis of NASA satellite data shows. A

browning trend significantly dwarfed smaller areas of "greening" — a satellite-derived indicator of forest health — during April, May, and June each year from 2000 to 2012, according to research published in Nature. The browning of Congo's rainforest is significant, researchers said, because most climate models forecast that tropical forests may face increasing stress and rainfall shortages in a warmer and drier 21st century. A continued drying trend might alter the composition and structure of the Congo rainforest, affecting its biodiversity and carbon storage, according to the study. "Recent climate anomalies as a result of climate change and warming of the Atlantic Ocean have created severe droughts in the tropics, causing major impacts on forests," a NASA researcher said.

 

22 Apr 2014: Run-of-River Hydropower Set
For Big Gains, Turbine Maker Predicts

A type of hydroelectric technology known as "run-of-river" hydropower is set to grow 10-fold over the next decade, potentially becoming a $1.4 billion industry,

according to Dutch turbine maker Tocardo International BV. Run-of-river hydropower stations redirect part of a waterway through a diversion to spin turbines and generate electricity. Run-of-river is considered a more benign type of hydropower than large dam projects because it is a smaller-scale technology that doesn't create large upstream reservoirs that flood ecosystems and disrupt a river's natural flow. Some conservation groups are concerned that problems with migratory fish passage and other environmental issues could outweigh the power-generating potential of run-of-river hydro projects. The company implemented its first project to harness tidal streams at Den Oever, Holland, and it has been operating for five years.

21 Apr 2014: Massive Data Crunch

The proportion of days in the United States that are warmer than the long-term average increased from 42 percent in 1964 to 67 percent today, according to an analysis of 3.2 million temperature anomalies over the last

50 years. Enigma.io, a New York City-based company that specializes in searches of information from public databases, examined data from 2,716 U.S. weather stations to track the temperature anomalies. The company found that since 1964, temperature anomalies characterized as warm or “strong warm” have increased by an average of .5 percent a year. Enigma’s data show, for example, that in 2012, 84 percent of temperature anomalies in the U.S. skewed on the warm side. The company forecast that by the 2030s more than 70 percent of anomalous temperatures in the U.S. are likely to be higher than the historical average, rather than colder.

 

An e360 Interview with Wendell Berry:
Strong Voice for Local Farms and the Land

Author Wendell Berry wrote about and practiced “sustainable agriculture” long before the term was widely used. His early writings in the 1970s, in which he argued against industrial agriculture and for small-scale, local-based farming, strongly influenced the U.S.

environmental movement. At age 79, Berry still speaks eloquently about the importance of local communities and of caring for the land, while warning about the destructive potential of industrialization and technology. In an interview with Yale Environment 360, he talked about his Kentucky farm and why he has remained there, why sustainable agriculture faces an uphill battle, and why strong rural communities are important. “A deep familiarity between a local community and a local landscape is a dear thing, just in human terms,” Berry said. “It’s also, down the line, money in the bank, because it helps you to preserve the working capital of the place.”
