Why the Fossil Fuel Divestment
Movement May Ultimately Win

by marc gunther
The fossil fuel divestment campaign has so far persuaded only a handful of universities and investment funds to change their policies. But if the movement can help shift public opinion about climate change, its organizers say, it will have achieved its primary goal.

A Clash of Green and Brown:
Germany Struggles to End Coal

A recent battle over imposing a “climate fee” on coal-fired power plants highlights Germany’s continuing paradox: Even as the nation aspires to be a renewable energy leader, it is exploiting its vast reserves of dirty brown coal.

Unnatural Disaster: How Climate
Helped Cause India's Big Flood

by daniel grossman
The flood that swept through the Indian state of Uttarakhand two years ago killed thousands of people and was one of the worst disasters in the nation’s recent history. Now researchers are saying that melting glaciers and shifting storm tracks played a major role in the catastrophe and should be a warning about how global warming could lead to more damaging floods in the future.

Beyond the Perfect Drought:
California’s Real Water Crisis

by glen macdonald
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.

The Big Waste: Why Do We <br />Throw Away So Much Food?

The Big Waste: Why Do We
Throw Away So Much Food?

Every year, a staggering 30 to 40 percent of what is grown and raised in the United States is thrown away. In the first of a two-part e360 video series, filmmaker Karim Chrobog looks at food waste in America — a problem with major human and environmental costs. The video focuses on Washington, D.C., which has taken steps to make sure food ends up with those who need it rather than in landfills. | WATCH THE VIDEO

Australia Is Too Robust to Kill

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.

Nicaragua Canal: A Giant Project
With Huge Environmental Costs

If Alaska’s Pebble Mine Proceeds


The proposed Pebble Mine in southwestern Alaska is a project of almost unfathomable scale. If the copper- and gold-mining project proceeds, the mine would cover 28 square miles and require the construction of the world’s largest earthen dam — 700 feet high and several miles long — to hold back a 10-square-mile containment pond filled with up to 2.5 billion tons of sulfide-laden mine waste. All this would be built not only in an active seismic region, but also in one of the most unspoiled and breathtaking places on the planet — the headwaters of Bristol Bay, home to the world’s most productive salmon fishery. In a photo essay, landscape photographer Robert Glenn Ketchum documents the lands and waters at risk from the project, whose fate is currently wending its way through the courts.

03 Aug 2015: California Has Missed Equivalent

Over the past three years of severe drought, California has accumulated a rain "debt" equal to a year's worth of precipitation, NASA

Drought conditions in the U.S. West
researchers report in the Journal of Geophysical Research — Atmospheres. The state is roughly 20 inches behind in total precipitation, the scientists calculate, which is the average amount expected to fall in the state in a single year. The deficit has been driven primarily by a lack of extreme precipitation events known as atmospheric rivers — water vapor-rich air currents that move inland from the Pacific Ocean — which, in an average year, provide 20 to 50 percent of California's precipitation. The researchers found that California also had a 27.5-inch precipitation deficit between 1986 and 1994. However, the state's population, industries, agriculture, and water demand have grown significantly since that time.

 

Interview: How to Get People
To Care About Climate Change

Per Espen Stoknes
bedeviled climate scientists for years: Why have humans failed to deal with the looming threat posed by climate change? That question is the focus of his recent book, What We Think About When We Try Not To Think About Global Warming, in which he analyzes what he calls the psychological barriers that have made it difficult to deal realistically with the climate crisis. In an interview with Yale Environment 360, Stoknes talks about these barriers and about how the discussion of climate change needs to be reframed. “We need a new kind of stories,” he says, “stories that tell us that nature is resilient and can rebound and get back to a healthier state, if we give it a chance to do so.”

31 Jul 2015: Severe Droughts Affect Forests
And CO2 Storage for Years, Study Shows

Severe drought can affect a forest's growth for up to four years, a period during which it is less effective at removing carbon

from the atmosphere, a new study reports in the journal Science. Standard climate models have assumed that forests and other vegetation bounce back quickly from extreme drought, but that assumption is far off the mark, the researchers say. Looking at data from more than 1,300 forest sites dating back to 1948, they found that living trees took an average of two to four years to recover and resume normal growth rates after droughts ended. Frequent droughts in places like the western U.S. could significantly impact the ability of forests to sequester carbon, the study found. Researchers aren't sure how drought causes these long-lasting changes, but they say there are likely three causes: Loss of carbohydrate and foliage reserves may impair growth; pests and diseases may accumulate in drought-stressed trees; and lasting damage to vascular tissues impairs water transport.

 

With Camera Drones, New Tool
For Viewing and Saving Nature


In a career spanning four decades, award-winning filmmaker Thomas Lennon has tackled topics as diverse as the Irish in America and a polluting chemical plant in China. But it was his current project — a short film about the Delaware River — that opened his eyes to what he sees as a revolutionary new tool for viewing the natural world: the camera drone. In an interview with Yale Environment 360, Lennon — who produced a video of drone images from the Delaware for e360 — describes how drones are a major innovation that allows filmmakers to capture images from vantage points never before possible. “There’s an opportunity for visual excitement, but combined — and this is the key — with intimacy,” Lennon says. “And I think that can become a tool for artists as well as for environmentalists.”

according to a United Nations report released today. The revised U.N. estimates counter previous projections, which had said that global population would peak at roughly 9 billion by 2050, then gradually decline. Most growth will occur in developing regions, the new report says, especially Africa, which is expected to account for more than half of the world’s population growth between 2015 and 2050. India is expected to become the most populous country, surpassing China around 2022. Nigeria could surpass the United States by 2050, which would make it the third-largest country in the world, the United Nations projects.
