Vanishing mangroves are carbon sequestration powerhouses
(04/05/2011) Mangroves may be the world's most carbon rich forests, according to a new study in Nature Geoscience. Measuring the carbon stored in 25 mangrove forests in the Indo-Pacific region, researchers found that mangroves forests stored up to four times as much carbon as other tropical forests, including rainforests. "Mangroves have long been known as extremely productive ecosystems that cycle carbon quickly, but until now there had been no estimate of how much carbon resides in these systems. That's essential information because when land-use change occurs, much of that standing carbon stock can be released to the atmosphere," explains co-author Daniel Donato, a postdoctoral research ecologist at the Pacific Southwest Research Station in Hilo, Hawaii.
World Bank proposes to limit funding to coal plants
(04/05/2011) Following years of criticism from environmentalists and some governments the World Bank has proposed new rules regarding carbon-intensive coal plants, reports the Guardian. The new rules would allow lending for coal-fired plants only to the world's poorest nations and would only lend after other alternatives, such as renewable energy, had been ruled out.
Carbon labeling good for consumers and business
(03/31/2011) Want to know how many calories are in a serving from that box of cereal? Simply turn it over and you can read a wealth of information: calories, fat, fiber, nutrients. But what if you’d like to know how much carbon was emitted to produce your breakfast? Currently, you're out of luck. But an article in Nature Climate Change argues that labeling products—from food to household products—with their carbon footprint could reduce emissions over time as consumers and companies react to better environmental transparency. A 'carbon footprint' measures the total amount of greenhouse gases emitted to produce a product or service.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
Clean energy investments rise 630% in 7 years
(03/29/2011) According to a report by the US Pew Environment Group global clean energy investments, which do not include nuclear power, jumped 630% since 2004. The report detailing 2010 clean energy investments found that China remains the global leader in clean energy, while the US fell from 2nd to 3rd. This is the second year in a row that the US fell: in 2009 it lost first place to China. In all $243 billion were invested in clean energy in 2010.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Arctic sea ice maximum ties for lowest on record
(03/24/2011) Providing more data on how climate change is impacting the Arctic, the maximum extent of sea ice this year was tied with 2006 for the lowest on record. Maximum sea ice simply means the territory the sea ice covers at its greatest point before the seasonal melt begins.
As US Republicans officially dismiss climate change, scientists charge them with 'willful ignorance'
(03/17/2011) US Republican congress members officially rejected the widespread scientific consensus that the world is warming and the cause is primarily greenhouse gas emissions. As Republicans in the US House and Commerce Committee voted to stop the US Environmental Protection Agency (EPA) from regulating greenhouse gas emissions, they were also forced to vote on three Democratic amendments asking congress to confirm the science behind climate change. The amendments failed as all 31 Republicans, representing the majority, voted against every amendment, summarily rejecting decades of climate research. However scientists have responded in a particularly scathing opinion piece in Nature, one of the world's most respected scientific journals.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Is Japan's tsunami linked to climate change?
(03/11/2011) Could the earthquake that triggered Japan's devastating tsunami be linked to climate change? The short answer is probably not, but recent research suggests that changing climate has the potential to influence earthquakes in some parts of the world
Republicans believe in climate change but not global warming
(03/09/2011) A new study finds that self-described Republicans are less skeptical of "climate change" than "global warming", reports Miller-McCune.
Melting ice sheets largest contributor to rising sea levels
(03/08/2011) Researchers expected the shrinking ice sheets of Antarctica and Greenland to eventually become the greatest contributor to the world's rising sea levels; they just didn't expect it to happen so quickly. A new study in Geophysical Research Letters has found that ice sheets have overtaken melting glaciers and ice caps.
Birnam Wood in the 21st Century: northern forest invading Arctic tundra as world warms
(03/07/2011) In Shakespeare's play Macbeth the forest of Birnam Wood fulfills a seemingly impossible prophecy by moving to surround the murderous king (the marching trees are helped, of course, by an army of axe-wielding camouflaged Scots). The Arctic tundra may soon feel much like the doomed Macbeth with an army of trees (and invading species) closing in. In a recent study, researchers found that climate change is likely to push the northern forests of the boreal into the Arctic tundra—a trend that is already being confirmed in Alaska.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Photo gallery: Borneo paradise saved from beachside coal plant
(02/22/2011) Last week the Malaysian government announced it had canceled a plan to build a coal-fired plant in the state of Sabah. The coal plant would have rested on a beach overlooking the Coral Triangle, one of the ocean's most biodiverse ecosystems, and 20 kilometers from Tabin Wildlife Reserve, a rainforest park home to endangered orangutans, Sumatran rhinos, Bornean elephants, and thousands of other species. The cancellation followed a long campaign by a group of environmental and human right organizations dubbed Green SURF (Sabah Unite to Re-power the Future), which argued that the coal plant would have imperiled ecosystems, ended artisanal fishing in the area, hurt tourism, and tarnished Sabah's reputation as a clean-green state.
Coal's true cost in the US: up to half a trillion
(02/20/2011) According to the global market coal is cheap, yet a new study in the Annals of the New York Academy of Sciences finds that the hidden costs of coal are expensive, very expensive. Estimating the hidden costs of coal, such as health and environmental impacts, the study found that burning coal costs the US up to $523 billion a year. Dubbed 'externalities' by economists, the paper argues that these costs are paid by the American public to the tune of $1,698 per person every year.
Environmentalists and locals win fight against coal plant in Borneo
(02/16/2011) Environmentalists, scientists, and locals have won the battle against a controversial coal plant in the Malaysian state of Sabah in northern Borneo. The State and Federal government announced today that they would "pursue other alternative sources of energy, namely gas, to meet Sabah's power supply needs." Proposed for an undeveloped beach on the north-eastern coast of Borneo, critics said the coal plant would have threatened the Coral Triangle, one of the world's most biodiverse marine ecosystems, and Tabin Wildlife Reserve, home to Critically Endangered Sumatran rhinos and Bornean orangutans. Local fishermen feared that discharges from the plant would have imperiled their livelihood.
Not enough data on world's tropical plants to predict impact of warming world
(02/14/2011) How many tropical plant species are threatened by climate change? Which plants have big enough ranges to survive a warming world, not to mention deforestation? How likely is it that the tropics are undergoing a current mass extinction? These questions may appear straight forward, but a new study in Global Change Biology finds that researchers lack the hard data necessary to come to any confident conclusions. According to the study, nine out of ten tropical plants from Africa, Asia, and South America lack the minimum number of collections needed (at least 20) to determine the species' range, and therefore predict the impact of climate change.
Prince Charles: 'direct relationship' between ecosystems and the economy
(02/09/2011) At an EU meeting in Brussels, dubbed the Low Carbon Prosperity Summit, the UK's Prince Charles made the case that without healthy ecosystems, the global economy will suffer.
Food crisis 2011?: drought in China could push food prices even higher
(02/09/2011) The UN's Food and Agriculture Organization (FAO) has warned that a drought in China could devastate the nation's winter wheat crop and further inflate food prices worldwide. Already, food prices hit a record high in January according to the FAO. Rising 3.4 percent since December, prices reached the highest point since tracking began in 1990. While many fear a food crisis similar to the one in 2008-2007, experts say the world has more food in reserve this time around and gasoline, at least for now, remains cheaper. However, if China loses its winter wheat that could scuttle any hopes of avoiding another price rise in crop staples.
Another low record for Arctic ice in January
(02/08/2011) The extent of ice cover in the Arctic for January was the lowest on record, following another record-low in December for that month, according to the National Snow and Ice Data Center (NSIDC).
Numerous causes, including climate change, behind record food prices
(02/07/2011) Food prices hit a record high in January according to the UN's Food and Agriculture Organization (FAO), threatening the world's poor. Rising 3.4% since December, the FAO stated that prices reached the highest point since the agency began tracking food prices in 1990. Given the complexity of world markets and agriculture, experts have pointed to a number of reasons behind the rise including rising meat and dairy consumption, the commodity boom, fresh water scarcity, soil erosion, biofuels, growing human population, and a warming world that has exacerbated extreme weather events like last year's heatwave in Russia.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Two massive droughts evidence that climate change is 'playing Russian roulette' with Amazon
(02/03/2011) In 2005 the Amazon rainforest underwent a massive drought that was labeled a one-in-100 year event. The subsequent die-off of trees from the drought released 5 billion tons of CO2. Just five years later another major drought struck. The 2010 drought, which desiccated entire rivers, may have been even worse according to a new study in Science, adding on-the-ground evidence to fears that climate change may inevitably transform the world's greatest rainforest.
From Cambodia to California: the world's top 10 most threatened forests
(02/02/2011) Growing populations, expanding agriculture, commodities such as palm oil and paper, logging, urban sprawl, mining, and other human impacts have pushed many of the world's great forests to the brink. Yet scientists, environmentalists, and even some policymakers increasingly warn that forests are worth more standing than felled. They argue that by safeguarding vulnerable biodiversity, sequestering carbon, controlling erosion, and providing fresh water, forests provide services to humanity, not to mention the unquantifiable importance of having wild places in an increasingly human-modified world. Still, the decline of the world's forests continues: the FAO estimating that around 10 million hectares of tropical forest are lost every year. Of course, some of these forests are more imperiled than others, and a new analysis by Conservation International (CI) has catalogued the world's 10 most threatened forests.
Is Obama's clean energy revolution possible?
(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world's largest economy. Describing the challenge as 'this generation's Sputnik moment' the US president set a goal of producing 80 percent of America's energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. "Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. "It is a question of whether we have the societal and political will."
Greenland melt is the worst yet
(01/24/2011) Melting of the Greenland ice sheet was the most extreme yet in 2010, beating the previous melt record from 2007. This continues a long-term trend whereby melting in Greenland has increased on average 17,000 square kilometers every year since 1979.
How Genghis Khan cooled the planet
(01/20/2011) In 1206 AD Genghis Khan began the Mongol invasion: a horse-crazed bow-wielding military force that swept through much of modern-day Asia into the Middle East and Eastern Europe. But aside from creating the world's largest empire, the Mongol invasion had another global impact that has remained hidden in history according to new research by Julia Pongratz of the Carnegie Institution's Department of Global Ecology. Genghis Khan and his empire, which lasted nearly two centuries, actually cooled the Earth.
NASA images reveal consistent climate warming among different temperature records
(01/19/2011) New images released by NASA illustrate how four different global temperature records show remarkably consistent warming around the world. Currently, global temperatures are analyzed by four major organizations: NASA Goddard Institute for Space Studies (GISS), NOAA National Climatic Data Center, Met Office Hadley Center’s Climatic Research Unit, and the Japanese Meteorological Agency. Although each organization has garnered slightly different results year-to-year, all show a consistent warming trend globally, including that the most recent decade as the warmest since record-keeping began in the late Nineteenth Century.
2010 ties for the warmest year on record
(01/14/2011) 2010 tied 2005 as the warmest year on record, according to separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA).
Agricultural innovation will reduce poverty, help stabilize climate change according to new report
(01/12/2011) With nearly a billion people people going hungry in the world today as 40 percent of the global food stock is wasted before it is consumed, many are seeking ways to increase the efficiency of the world's food system. Worldwatch Institute, an environmental sustainability and social welfare research organization, today released State of the World 2011: Innovations that Nourish the Planet, which highlights recent successes in agricultural innovation and outlines ways to reduce global hunger and poverty while at the same time minimizing the impact of agriculture on the environment.
New Zealand: Can you sink a rainbow?
(01/12/2011) In a world wracked by Cold War, New Zealand’s Prime Minister, David Lange defends the country’s fledgling nuclear free policy by refusing the nuclear warship USS Buchanan’s entry into New Zealand’s shores. A historic day. He had received an almost unprecedented standing ovation at the Oxford Union Debate four months earlier where he had successfully argued the proposition that "nuclear weapons are morally indefensible". He was held high in the estimations of dedicated environmental group, Greenpeace for doing this, who were also fighting for the cease of nuclear testing and for New Zealand to be a leader in environmental protection. In addition, he was respected by his country for his bold stand.
Photos: Scientists race to protect world's most endangered corals
(01/11/2011) As corals around the world disappear at alarming rates, scientists are racing to protect the ones they can. At a workshop led by the Zoological Society of London (ZSL), the world's foremost coral experts met in response to a decade of unprecedented reef destruction to identify and develop conservation plans for the ten most critically endangered coral species.
Atlantic ocean warming confirmed by corals
(01/05/2011) A new study investigating the ability of coral to record sea temperatures indicates that the Northwestern Atlantic has experienced unprecedented warming during the past 150 years.
U.S. bumble bees experiencing significant declines
(01/04/2011) Many US bumble bee populations have declined significantly over the past few decades, with certain species dropping off by as much as 96%. While the decline is linked to low genetic diversity and disease, an underlying cause remains uncertain.
Growing Atlantic dead zone shrinks habitat for billfish and tuna, may lead to over-harvest
(12/29/2010) A dead zone off the coast of West Africa is reducing the amount of available habitat for Atlantic tuna and billfish species, reports the National Oceanic and Atmospheric Administration in a study published in Fisheries Oceanography. The zone is growing due to global warming and is expected to cause over-harvest of tuna and billfish as the fish seek higher levels of oxygen in areas with greater fisheries activity.
Malaysia undermines commitment to protect Coral Triangle, backtracks on climate pledge
(12/22/2010) The Malaysian government will proceed with a plan to install a second-hand coal plant from China on the edge of the Coral Triangle in Borneo despite widespread condemnation from environmental groups and local people, reports Green SURF, a coalition that opposes the project.
Wikileaks reveals Dalai Lama's climate change concerns
(12/21/2010) As disclosures from the Wikileaks scandal continue to reverberate, the public is learning about hidden U.S. diplomacy in all far corners of the globe. The latest unlikely story involves the Tibetan Dalai Lama no less, who spoke with American diplomats last year about climate change high atop the Himalayan Mountains. In a meeting with U.S. ambassador to India Timothy Roemer, the Dalai Lama argued that the U.S. should seek to employ a different strategy toward Tibet. Instead of pressuring Beijing on the political front, the Dalai Lama declared, Washington should seek to leverage environmental concerns in the hope of buying some relief for the Tibetan people.
Top 10 Environmental Stories of 2010
(12/20/2010) Below is a quick review of some of the biggest environmental stories of 2010: Climate change rears it ugly head; Oil spill in the Gulf; Agreement to save global biodiversity; Illegal logging crisis in Madagascar; REDD kicks off in Indonesia; Brazil deforestation falls to its lowest level; Hungary's red sludge; Nestle caves to social media activists; New mammals galore' and Global climate framework back on the table?
Climate change could cut premontane forests of Argentina and Bolivia in half
(12/19/2010) A new study in mongabay.com's open access journal Tropical Conservation Science finds that the premontane forests of Argentina and Bolivia are susceptible to large-scale shifts due to climate change, losing over half of the ecosystem to warmer temperatures. Apart of the Yungas tropical forests, premontane forests are the lowest in the Andes, covering hills and flatland; these forests harbor significant biodiversity, yet many of those species may become threatened as the world warms.
California approves cap-and-trade under global warming law
(12/17/2010) The California Air Resources Board voted 9-1 to adopt cap and trade regulations for AB32, California's 2006 climate law. The move, which establishes the first compliance carbon trading system in the United States, opens the door for carbon offsets generated via forest conservation projects.
NASA releases global warming map
(12/15/2010) NASA has released a new analysis of temperature change.
Climate agreement reached in Cancun
(12/13/2010) Ministers meeting in Cancun, Mexico reached a series of agreements that include measures to reduce greenhouse gas emissions, a goal of limiting the global average temperature increase to 2°C, greater protections for forests, and a new U.N.-administered climate fund finance mitigation and adaptation activities in developing countries. While the 'Cancun Agreement' doesn't set any binding targets, it lays the groundwork for a successor treaty to the Kyoto Protocol, which expires in 2012.
Can RED Hot California Heat Up A Sedated Cancun?
(12/07/2010) In his concession speech after the 2010 mid-term elections, President Obama said that prospects for meaningful U.S. climate change legislation are doubtful and will be for years. With the US and the international community unable to take even modest steps to combat global warming, the State of California has stepped up in a big, big way. Despite record unemployment rates, deficits and unemployment, California voters trounced a measure that would have suspended AB 32, California's landmark climate change law. California's AB 32 cap and trade program will soon be the biggest market for compliance emission reductions outside of Europe. In the wreckage of the Copenhagen talks and the new political landscape in America, California is the most dynamic jurisdiction for climate change implementation.
US most vulnerable to climate change among world's wealthy nations
(12/06/2010) While the US has done little to mitigate climate change, a new report by humanitarian research organization DARA and the Climate Vulnerable Forum states that of all industrialized nations the US will face the most harm from a warming world. Together with Spain, the US's vulnerability to climate change has been listed as High by the newly released Climate Vulnerability Monitor.
Climate change to take the lives of 5 million by 2020, mostly children
(12/06/2010) A new report by humanitarian research organization DARA and the Climate Vulnerable Forum finds that if nations continue to fail at lowering greenhouse gas emissions, five million people—mostly children—are likely to die from climate change impacts over the next 10 years. The report, called the Climate Vulnerability Monitor, predicts, in addition, that by 2030, one million people every year will perish from climate change impacts. The dire predictions come as nations struggle at a UN Climate Summit in Mexico this week to come up with a coordinated response to climate change, although an agreement is not expected this year.
'These are the facts': 2010 to be among top three hottest years
(12/02/2010) Despite La Nina arriving at the end of the year—which bring cooler than average conditions—and bitter cold showing up recently in the Northern Hemisphere due to the North Atlantic Oscillation (NAO), 2010 was smoldering enough worldwide that it will very likely be among the top three hottest years since record-keeping began 160 years ago, reports the World Meteorological Organization (WMO) today.
Climate change linked to 21,000 deaths in nine months
(11/30/2010) Extreme weather events linked to climate change has caused the deaths of 21,000 people worldwide in the first nine months of 2010, according to Oxfam. This is already twice the casualties of 2009. In a new report More than ever: climate talks that work for those that need them most, the organization outlines the casualties of such weather-related disasters, for example devastating floods in Pakistan which killed 2,000 people and affected more than 20 million.
Consumer goods industry announces goal of zero deforestation in Cancun
(11/30/2010) While governments continue to stall on action to cut greenhouse gas emissions worldwide, global corporations are promising big changes to tackle their responsibilities. The Board of Consumer Goods Forum (BCGF) has approved a resolution to achieve net zero deforestation by 2020 in products such as palm oil, soy, beef, and paper. Announced yesterday at the UN Climate Summit in Cancun, the BCGF has stated the goal will be met both by individual actions within companies and collective action, including partnerships with NGOs, development banks, and governments. With such giants as Walmart, Unilever, Carrefour, and General Mills, BCGF is made up of four hundred global consumer goods manufacturers and retailers totaling over $2.8 trillion in revenue.
Earth could see 4 degrees Celsius warming in less than a lifetime
(11/29/2010) By the time children born this year reach 50 years old, the Earth could be 4 degrees Celsius warmer (7.2 degrees Fahrenheit) warns a new study as governments meet in Cancun for this year's UN climate summit, which is not expected to produce an agreement. Last year governments pledged in the non-binding Copenhagen Accord to keep temperatures below a 2 degree Celsius rise, but a new study in Philosophical Transactions of the Royal Society A argues that even with current promises to cut emissions this is unlikely and, in a worst-case scenario, a rise of 4 degrees Celsius is possible by 2060.
