Forests worldwide near tipping-point from drought
November 24, 2012 08:19 AM - Editor, MONGABAY.COM

Forests worldwide are at "equally high risk" to die-off from drought conditions, warns a new study published this week in the journal Nature. The study, conducted by an international team of scientists, assessed the specific physiological effects of drought on 226 tree species at 81 sites in different biomes around the world. It found that 70 percent of the species sampled are particularly vulnerable to reduction in water availability. With drought conditions increasing around the globe due to climate change and deforestation, the research suggests large swathes of the world's forests — and the services they afford — may be approaching a tipping point.

Climate change predicted to hit poorest hardest
November 20, 2012 07:01 AM - EurActive

All nations will suffer the effects of a warmer world, but the world's poorest countries will suffer most from food shortages, rising sea levels, cyclones and drought, the World Bank’s new report on climate change says. Under new World Bank President Jim Yong Kim, a former scientist, the global development lender has launched a more aggressive stance to integrate climate change into development. "We will never end poverty if we don't tackle climate change. It is one of the single biggest challenges to social justice today," Kim told reporters on Friday [16 November].

What History Teaches Us About Our Environmental Challenges
November 19, 2012 07:05 AM - Roger Greenway, ENN

It seems that the environmental challenges we face are truly daunting. That we may never be able to survive them, even if we do our best to do so. A study by MIT professor Susan Solomon says it's often helpful — and heartening — to look to the past. Solomon points out that recent decades have seen major environmental progress: In the 1970s, the United States banned indoor leaded paint following evidence that it was poisoning children. In the 1990s, the United States put in place regulations to reduce emissions of sulfur dioxide — a move that significantly reduced acid rain. Beginning in the 1970s, countries around the world began to phase out leaded gasoline; blood lead levels in children dropped dramatically in response.

Idea that we have reached "Peak Oil" incorrect
November 18, 2012 07:18 AM - Population Matters

A report by theInternational Energy Agency reminds us that the peak oil idea has gone up in flames, and that the truly global implications of the 2012 report lie in the warning that we must leave most of our fossil fuels in the ground, writes Damian Carrington writes on the Guardian’s Environment Blog. Given the bubbling cauldron of violence that the middle East so frequently and regrettably is, the prospect of the US outstripping Saudi Arabia as the world’s biggest oil producer in the next decade is deeply striking. The redrawing of the geopolitical map may cool some tensions and perhaps spark others. But the truly global implications of the International Energy Agency’s flagship report for 2012 lie elsewhere, in the quietly devastating statement that no more than one-third of already proven reserves of fossil fuels can be burned by 2050 if the world is to prevent global warming exceeding the danger point of 2C. This means nothing less than leaving most of the world’s coal, oil and gas in the ground or facing a destabilised climate, with its supercharged heatwaves, floods and storms.

Can Overfished Tuna be Saved?
November 17, 2012 07:42 AM - Roger Greenway, ENN

We love Tuna! We love to eat Tuna! And the great Tuna are being seriously overfished. Attempts to remedy this situation have not been effective to date. Now the University of Hawaii has come up with a new approach that holds promise. A fish modelling study has found that marine zoning in the Pacific Ocean, in combination with other measures, could significantly improve numbers of heavily overfished bigeye tuna and improve local economies. Scientists working at the University of Hawai'i at Mānoa, the Secretariat of the Pacific Community (SPC, Noumea, New Caledonia) and Collecte Localisation Satellites (CLS, Toulouse, France), have found that a network of marine zones in the Pacific Ocean could be a more effective conservation measure than simply closing relatively small areas to some types of fishing. These marine zones, where different fishing activities are allowed in different areas, may have significant and widespread benefits for bigeye tuna numbers.

US Military Takes Part in Reducing Ecological Footprint
November 16, 2012 09:51 AM - Richard Matthews, Global Warming is Real

In an effort to enhance American security and address climate change, the U.S. military is diminishing its footprint. The military is producing cleaner power, reducing energy consumption, managing water and minimizing waste. Their efforts encompass vast numbers of vehicles, ships, planes, buildings, lands, and other facilities. A major impetus for these efforts is Executive Order 13514, "Federal Leadership in Environmental, Energy, and Economic Performance," which President Obama signed on October 5, 2009. It mandates a 30 percent reduction in energy usage by federal agencies.

How the Worm Can Help Landfills and Sustainable Farming
November 16, 2012 09:15 AM - Jan Lee, Triple Pundit

High in the northern mountains of Guatemala, near the ancient city of Quetzaltenango, there's an unusual new venture that is helping transform the way local communities think about the garbage they throw into landfills. It's also reforming the way people think about nature's most industrious ecologist: the worm. María Rodriguez, founder of Byoearth is teaching women the value of the red wiggler worm and the use of vermicomposting to support sustainable farming. It's a concept she believes in passionately and is having increasing success selling to both local farmers and non-profit aid organizations throughout Latin America.

Let's Celebrate America Recycles Day by taking the Food Recovery Challenge!
November 15, 2012 09:09 AM - Allison Winter, ENN

Today is America Recycles Day, a nationally recognized day dedicated to promoting recycling in the US. All across the country, thousands of events are being held to celebrate recycling awareness in communities. One way organizations are participating this year is by taking the Food Recovery Challenge. The Food Recovery Challenge is a voluntary program established by the EPA with a goal to cut the 35 million tons of food wasted nationwide annually by reducing unnecessary consumption and increasing donations to charity and composting.

Great Potential for Energy Efficiency Improvements in UK
November 15, 2012 06:07 AM - Tina Casey, Triple Pundit

With the ambitious goal of kickstarting "a revolution in UK energy efficiency," England’s Department of Energy and Climate Change (DECC) has just launched a new program called the Government's Energy Efficiency Strategy. The goal is to cut the equivalent of 22 power stations worth of energy consumption throughout the United Kingdom by 2020. Though the UK has already made some significant progress in energy efficiency, the new strategy underscores just how much more opportunity there is to save energy in a nation that boasts an impressive stock of centuries-old buildings. The challenges of upgrading castles, cottages and ancient estates is small potatoes, though, compared to some broader structural challenges the UK faces, and the DECC is not shy about laying those out.

Report: Climate-Related Migration
November 14, 2012 05:31 AM - Editor, Worldwatch Institute

Recent reports, as well as extreme weather events such as Superstorm Sandy, suggest that climatechange, and particularly sea-level rise, may be occurring faster than earlier anticipated. This has increased public and policy discussions about climate change’s likely impacts on the movement of populations, both internally and worldwide. Research suggests that when climate-related migration does occur, much of it is short distance and within national borders, as opposed to international, according to new analysis conducted by Lori Hunter, Associate Professor of Sociology at the University of Colorado at Boulder, for the Worldwatch Institute’s Vital Signs Online service (www.worldwatch.org). Recent research has added nuance to the scientific understanding of the potential connections between climate change and human migration. Previous studies over the past two decades relied largely on descriptive data and simplistic assumptions to put forward at-times alarmist estimates of future numbers of "environmental refugees," ranging from 150 million to 1 billion people. But such broad-sweeping generalizations mask several central issues that are important in the development of appropriate policy responses. These include:
