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.
Island nations say climate treaty should be completed in 2011
(11/29/2010) The Alliance of Small Island States (AOSIS), making up 42-island and low-lying coastal nations, has told Reuters that a deadline should be set for the UN climate treaty to be completed by 2011. After a disappointing meeting in Copenhagen last year and the low expectations for the up-coming climate change conference in Cancun, the AOSIS says a hard deadline should be set for 2011.
Unprecedented tundra fire likely linked to climate change
(11/23/2010) A thousand square kilometers of the Alaskan tundra burned in September 2007, a single fire that doubled the area burned in the region since 1950. However, a new study in the Journal of Geophysical Research finds that the fire was even more unprecedented than imagined: sediment cores found that it was the most destructive fire in the area for at least 5,000 years and maybe longer. "If such fires occur every 200 years or every 500 years, it's a natural event," University of Illinois plant biology professor Feng Sheng Hu explains in a press release. "But another possibility is that these are truly unprecedented events caused by, say, greenhouse warming."
Record number of nations hit all time temperature highs
(11/23/2010) To date, nineteen nations have hit or matched record high temperatures this year, according to Jeff Master's Wunder Blog, making 2010 the only year to have so many national records. In contrast, no nation this year has hit a record cold temperature.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
2009 carbon emissions higher than expected
(11/22/2010) Despite a global economic recession and ongoing concerns about the impacts of climate change, last year's global carbon emissions were the second highest on record, according to the Global Carbon Project (GCP). Emissions in 2009 were just below the record emissions of 2008. In addition, 2009 emissions were higher than predicted, falling by only 1.3% from 2008 to 2009, instead of the predicted 2.8%.
Cancún Climate Summit: Time for a New Geopolitical Architecture
(11/22/2010) As we approach crucial climate change negotiations in Cancún, Mexico the key question on many people’s minds is this: what nation or nations will have the courage to stand up to the United States, which still represents the key obstacle to a binding agreement on global warming? If it looked unlikely that the U.S. would reduce carbon emissions before, the recent midterm elections have made such a possibility seem even more remote: many incoming Republican legislators simply deny that global warming exists.
Rainforests thrived in warmer conditions in the past, yet study requires "caution"
(11/11/2010) A new study in Science is likely to reopen the contentious debate about the impact of climate change on tropical rainforests. Scientific modeling of future climate conditions in tropical rainforests, such as the Amazon, has shown that climate change—combined with deforestation and fire—could create a tipping point whereby a significant portion of the Amazon could turnover to savannah, pushing untold species to extinction and undercutting the many ecosystem services provided by tropical rainforests. Yet, a new study headed by Carlos Jaramillo, staff scientist at the Smithsonian Tropical Research Institute (STRI), has found a tropical forest ecosystem thriving in much warmer conditions than today.
It's not just size that matters: how population affects climate change
(11/11/2010) As the world's population increases, a surge in the number of older adults and the movement of people from the countryside to crowded cities will significantly affect levels of carbon dioxide emissions by 2050, according to a sweeping study published in the 11 October issue of the Proceedings of the National Academy of Sciences. A significant but attainable slowing of the planet's growing population could achieve up to 29 percent of the total decrease in emissions needed to stave off the harmful consequences of climate change by 2050, according to the study.
Beyond gloom: solutions to the global coral reef decline
(11/10/2010) The world's coral reefs are in trouble. Due to a variety of factors—including ocean acidification, warming temperatures from climate change, overfishing, and pollution—coral cover has decline by approximately 125,000 square kilometers in the past 50 or so years. This has caused some marine biologists, like Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, to predict that coral reefs will be largely extinguished within a century. This year alone, large-scale coral bleaching events, whereby coral lose their symbiotic protozoa and become prone to disease and mortality, were seen off the coasts of Indonesia, the Philippines, and some Caribbean islands. However a new paper in Trends in Ecology and Evolution attempts to dispel the gloom over coral reefs by pointing to strategies, and even some successes, to save them.
Will biodiversity agreement save life on Earth?
(11/07/2010) On Friday, October 29th, 193 member nations of the Convention on Biological Diversity (CBD) reached a possibly landmark agreement on saving the world's suffering biodiversity in Nagoya, Japan. The agreement was especially notable after nations failed—by all accounts—to live up to the goals from the previous CBD agreement, including stemming the global loss of biodiversity by 2010. According to scientists, the world's species continue to vanish at mass-extinction rates due to habitat loss, deforestation, overconsumption, pollution, climate change, and invasive species. To addresses this crisis the new CBD agreement sets out 20 goals for 2020. But given the global challenges in saving the world's species and the lack-of-teeth in agreement (it is strictly voluntary), will the CBD make a difference or in ten years time will goals be again unmet and life on planet Earth worse off than ever? To answer this mongabay.com turned to a number of experts in the conservation world.
US elects barrage of climate change deniers, threatening support for green energy
(11/03/2010) The US midterm election, which won Republicans the House but safeguarded the Senate for Democrats, has brought in a number of self-proclaimed climate change deniers, ending any likelihood that an energy bill will be passed over the next two years and essentially stumbling the White House's strategy on climate change. Newly elected Republican Senators Rand Paul of Kentucky and Marc Rubio of Florida, both members of the nascent Tea Party, have stated they do not believe in climate change despite that scientists overwhelming agree the Earth is warming due to human impacts.
Tropical agriculture "double-whammy": high emissions, low yields
(11/02/2010) Food produced in the tropics comes with high carbon emissions and low crop yields, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). In the most comprehensive and detailed study to date looking at carbon emissions versus crop yields, researchers found that food produced in the tropics releases almost double the amount of carbon while producing half the yield as food produced in temperate regions. In other words, temperate food production is three times more efficient in terms of yield and carbon emissions.
World's rarest snake making a comeback
(11/02/2010) The Antiguan racer (Alsophis antiguae) shares a similar story with many highly endangered island species. Invasive mongoose killed every racer on the Caribbean island of Antigua, leaving only a small population on nearby Great Bird Island. Confined to 8 hectares, this final population was being killed-off by invasive Eurasian black rats. By the time conservationists took action, only 50 Antiguan racers survived in the world. But here's where the story turns out different: 15 years later, a partnership between six conservation groups has succeeded in raising the population tenfold to 500 snakes and expanded its territory to other islands through snake-reintroductions.
Mixed messages on geoengineering: international community approves moratorium, US pushes research
(10/31/2010) Efforts to explore geoengineering, whereby governments would employ large-scale projects to alter the world's climate in a bid to combat climate change, received mixed messages this week. In Nagoya, Japan—where all but three of the world's nations (the US, Andorra, and the Holy See) met at the Convention on Biological Diversity (CBD) to hammer out an agreement on stemming biodiversity loss—member nations agreed on Friday to a moratorium on geoengineering schemes. On the same day a US congressional report on geoengineering, which it termed climate engineering, recommended "research now to better understand which technologies or methods, if any, represent viable stopgap strategies for managing our changing climate."
Undergrads in the Amazon: American students witness beauty and crisis in Yasuni National Park, Ecuador
(10/28/2010) Although most Americans have likely seen photos and videos of the world's largest rainforest, the Amazon, they will probably never see it face-to-face. For many, the Amazon seems incredibly remote: it is a dim, mysterious place, a jungle surfeit in adventure and beauty—but not a place to take a family vacation or spend a honeymoon. This means that the destruction of the Amazon, like the rainforest itself, also appears distant when seen from Oregon or North Carolina or Pennsylvania. Oil spills in Ecuador, cattle ranching in Brazil, hydroelectric dams in Peru: these issues are low, if not non-existent, for most Americans. But a visit to the Amazon changes all that. This was recently confirmed to me when I traveled with American college students during a trip to far-flung Yasuni National Park in Ecuador. As a part of a study abroad program with the University of San Francisco in Quito and the Galapagos Academic Institute for the Arts and Sciences (GAIAS), these students spend a semester studying ecology and environmental issues in Ecuador, including a first-time visit to the Amazon rainforest at Tiputini Biodiversity Station in Yasuni—and our trips just happened to overlap.
Brazil to impose levy on oil profits to fund climate change adaption, mitigation
(10/26/2010) Brazil will fund climate change mitigation and adaption projects through a levy on domestic oil production, reports Reuters.
BP funneling money to climate change denying candidates in US
(10/25/2010) BP, who was responsible for the US's worst environmental disaster to date, has been funneling thousands of dollars to politicians in the US known for denying the science of climate change according to the Guardian. A report by Climate Action Network Europe has found that a number of big European companies have been funding candidates such as James Inhofe from Oklahoma, who has called climate change a 'hoax' and compared environmentalists to the Third Reich.
Amazon suffers worst drought in decades
(10/24/2010) The worst drought since 1963 has created a regional disaster in the Brazilian Amazon. Severely low water levels have isolated communities dependent on river transport. Given a worsening situation, Brazil announced on Friday an emergency package of $13.5 million for water purification, tents, and food airdrops.
