Point/Counterpoint: Is It Time for Greens
To Reassess Their Opposition to Ethanol?

Environmentalists have for years dismissed corn ethanol as bad for the planet. But former U.S. Senator Tim Wirth and former White House Counsel C. Boyden Gray argue that the critics of ethanol are wrong and that increasing the amount of ethanol in gasoline would actually reduce air pollution and lower greenhouse gas emissions. In a rebuttal, economist C. Ford Runge counters that any revisionist view of ethanol ignores its negative impacts on the environment and the food supply.

Abrupt Sea Level Rise Looms
As Increasingly Realistic Threat

by nicola jones
Ninety-nine percent of the planet's freshwater ice is locked up in the Antarctic and Greenland ice caps. Now, a growing number of studies are raising the possibility that as those ice sheets melt, global sea levels could rise by six feet this century, and far higher than that in the next, flooding many of the world’s populated coastal areas.

For the Endangered American Eel,
A Long, Slippery Road to Recovery

The American eel isn’t just a U.S. native. It’s also indigenous to Greenland, Iceland, eastern Canada, and parts of Central and South America. Despite this expansive range, the International Union for Conservation of Nature lists the species as “endangered.”

Heather Perry
It would be in even worse shape without the Delaware River, which flows unimpeded 330 miles through New York, Pennsylvania, New Jersey, and Delaware. Few, if any, eel refuges are more important, and management on the Delaware provides a global blueprint for eel recovery. The upper watershed is protected as a Wild and Scenic River corridor and as the water supply for New York City, and last June, New York State banned fracking in its part of the basin. Compare the Delaware with the nearby Susquehanna River, where the Conowingo Dam has wiped out 400 miles of eel habitat on the main river. But here and elsewhere eel recovery is underway.

26 May 2016: More Solar Energy Jobs Exist
In U.S. Than in Oil and Gas Sector

Solar energy now supports more jobs in the U.S. than either the oil and gas industry or coal mining, according to a new report from the International Renewable Energy Agency (IRENA).

Alex Snyder
Solar jobs grew at a rate 12 times faster than general U.S. job market growth. Worldwide, employment in green energy grew 5 percent in 2015, to 8.1 million jobs, IRENA reported. The 58 percent drop in oil prices since 2014 caused many fossil fuel companies to lay off workers — more than 350,000 people worldwide since the slump began. The IRENA report says clean energy jobs could triple to 24 million by 2030 if nations follow through on the climate pledges they made in Paris last year. “This increase is being driven by declining renewable energy technology costs and enabling policy frameworks,” said Adnan Amin, director-general of IRENA.

 

Interview: CO2 'Air Capture' Could
Be Key to Slowing Global Warming

For two decades, Klaus Lackner has pioneered efforts to combat climate change by pulling carbon dioxide from the atmosphere.

Klaus Lackner
Now, after years of watching the global community fail to bring greenhouse gas emissions under control, Lackner — director of the Center for Negative Carbon Emissions at Arizona State University — is delivering a blunt message: The best hope to avoid major disruptions from global warming is to launch a massive program of CO2 "air capture" that will begin to reverse the buildup of billions of tons of carbon in our atmosphere. "We need to have the ability to walk this backwards," says Lackner. "I'm saying this is a war, and we need to use all the weapons at our disposal. You don't want to get into this fight with one hand tied behind your back."

25 May 2016: Could This Straddling Bus Help
Solve China’s Air Pollution Problem?

With an estimated 20 million new drivers on the road each year, China has long struggled to control its CO2 emissions, air pollution, and traffic problems.

YouTube/Xinhua
But a Beijing-based transit company is planning to test a new straddling bus this summer that could provide some relief, according to Chinese news agency Xinhua. The bus, which can carry up to 1,400 passengers, hovers above the road, letting smaller vehicles pass underneath. Because it operates on existing roadways, the system is much cheaper to build than underground subways, while carrying the same number of people. The idea of a straddling bus has been around since 1969, but has remained a far-fetched concept until recent years. A model of the system, designed by Transit Explore Bus, was unveiled at the International High-Tech Expo in Beijing this month. The company plans to build and test an actual straddling bus in Changzhou this summer.

 

Bringing Energy Upgrades
To the Nation’s Inner Cities

America’s low-income urban areas are filled with aging buildings that are notoriously energy-inefficient. It’s a problem that Donnel Baird sees as an opportunity. Baird is CEO and cofounder of BlocPower,

a startup that markets and finances energy-upgrade projects in financially underserved areas. Founded in 2013 with venture capital seed money, BlocPower bundles small energy-improvement projects together — from barber shops to churches —and sells them to potential investors. In an interview with Yale Environment 360, Baird describes how BlocPower’s projects not only create jobs and reduce carbon emissions, but also raise awareness of global warming in inner-city communities. “It is not possible for the climate change movement to win anything significant without the participation of people of color,” says Baird.

24 May 2016: Peru Declares Emergency to
Fight Mercury Pollution from Gold Mines

Peru has declared a 60-day emergency in the Amazon due to widespread mercury pollution from the region’s booming gold mining industry, the country's environment minister announced this week.

Marcin Nowak/Wikimedia
Several studies have confirmed dangerously high levels of the neurotoxin in waterways, fish, and people living in the Madres de Dios region, near Peru’s southeast border. Members of the Harakmbut indigenous group, for example, have mercury levels in their bodies six times higher than what doctors deem safe. Mercury is used to separate gold from ore, but it can have serious health impacts, including damaging brain, kidney, and lung function. In illegal mining operations — which make up the majority of mines in the Peruvian Amazon — workers often handle the substance with bare hands, and dump excess mercury into nearby rivers. During the 60-day emergency period, the government will supply uncontaminated fish to local communities and set up mobile health clinics.
