Algal Biofuel Blend
Reaches Market at California Gas Stations
A U.S. company this week began pumping a mix of an algae-based biofuel and gasoline at gas stations in California
, a pilot project the company hopes will be a first step in providing a large-scale alternative to fossil fuels.
The fuel, known as Biodiesel B20, contains 80 percent petroleum and 20 percent algae grown by San Francisco-based Solazyme. The fuel is produced in a fermentation process at Solazyme’s Illinois plant that combines sugar with an organism company officials will not identify. According to the company, the new fuel blend produces 30 percent fewer particulates, 20 percent less carbon monoxide, and 10 percent fewer hydrocarbons than other biodiesel fuels. So far, the fuel is being sold for diesel vehicles at four gas stations in the Bay Area for $4.25 per gallon, which is also the average price right now for diesel fuel in California. But Propel Fuels, which is providing the infrastructure for the fuel delivery, hopes to make the fuel available at hundreds of California stations, said Matt Horton, Propel’s CEO.

New Disney Paper Policy
Promises Responsible Use and Sourcing
The Walt Disney Co., the world’s largest publisher of children’s books, has announced a dramatic shift in how the company will use and source paper
, vowing to minimize the amount of paper it uses overall and eliminate its purchase of irresponsibly harvested timber products. In an announcement, the multinational media company, which had been under pressure from forest activists, said it would increase its use of recycled paper and paper products certified by the Forest Stewardship Council and will avoid products coming from what it called “high conservation-value” and “high carbon-value” forests. In addition, executives say they will work with the Rainforest Action Network (RAN) and other groups to identify "regions with poor forest management and high rates of deforestation,” including Indonesia, where rampant deforestation for pulp and paper products is decimating rainforests. The policy shift comes two years after RAN launched a campaign against Disney, citing evidence that its publishing arm, which produces 50 million books and 30 million magazines annually, was using hardwood pulp likely sourced in Indonesia rainforests

Decline in Fisheries
Can Still be Reversed, Study Says
Although the majority of global fisheries remain in decline, they can still rebound if managed sustainably
, according to a new study. In a comprehensive statistical analysis of the world’s 10,000 fish stocks, nearly 80 percent of which are not regulated, a team of U.S. scientists found that the world’s smaller, managed fisheries are in far worse shape than larger, regulated ones. But while those smaller fisheries, such as those for snapper, are in steep decline, “they’re not yet collapsed,” said Christopher Costello, an economist at the University of California at Santa Barbara and lead author of the study, published in the journal Science
. According to the analysis, effective management of unregulated fisheries could boost global fish abundance by 56 percent. “If we turn things around now, we can recover them in a matter of years, not decades, and that has big implications for conservation and food security,” Costello said. According to the study, major gains have been made in large fisheries, such as skipjack and albacore tuna, where strong science-based management policies have been enacted
, including the closing of some areas to let stocks recover.

U.S. Fishing Catch Reached
17-Year High in 2011, NOAA Says
U.S. commercial fishermen landed more than 10.1 billion pounds of fish and shellfish in 2011, a 17-year high attributed in part to policies aimed at rebuilding fisheries nationwide, according to a report from the National Oceanic and Atmospheric Administration (NOAA)
. The annual catch was 22.6 percent greater than 2010 and, with a value of $5.3 billion, a 17-percent increase in value compared with a year earlier. Officials say catch increases are evidence that fish populations are increasing due to better fisheries management. While all nine of NOAA’s fishing regions saw an increase in catch volume and value, much of the overall increase was a result of increased catches of Gulf of Mexico menhaden, Alaskan pollock, and Pacific hake. NOAA said key fisheries remain at risk
, with disasters declared for the cod fishery in New England, oyster and blue crab fisheries in Mississippi, and Chinook salmon in Alaska’s Yukon and Kukokwin rivers.

Japanese Set Goal
To Phase Out Nuclear Power by 2040
The Japanese government says it will seek to phase out all nuclear power plants by 2040
, although officials suggested that the target remains flexible. The new energy strategy, which places a 40-year lifespan on nuclear reactors and limits construction of new plants, would continue a national shift away from nuclear power following last year’s disaster at the Fukushima nuclear power station. Earlier this year Japan suspended operations at the last of its 50 nuclear power stations
over public safety concerns. Most of the plants remain off-line. In announcing the new plan, Motohisa Furukawa, Japan’s minister of state for national policy, left open the possibility that five reactors that will be younger than 40 at the end of the 2030s will be allowed to remain in operation. In addition, Furukawa indicated that the central government would ultimately bow to a newly formed nuclear panel over such policy questions, the New York Times
reported. Nuclear power provided nearly 30 percent of the nation’s electricity before the 2011 disaster, and many have questioned whether the country can meet its power needs without a nuclear sector.

U.S. Big-Box Retail Stores
Lead Surge in Solar Power Installations
A growing number of major U.S. companies, led by the nation’s largest big-box retailers, are installing rooftop solar power systems to help cut energy costs and increase profits, a new report says
. According to the report, released by the Solar Energy Industries Association (SEIA) and the Vote Solar Initiative, more than 3,600 non-residential systems were activated
in the U.S. during the first half of 2012, led by retail giants such as Walmart, Costco, and Kohl’s department stores, all of which have sharply increased their solar power installations in recent months. Among the top 20 U.S. companies
by solar capacity, almost half are big-box retailers, according to the report. “Five or six years ago, you probably would have read about a pledge in an annual report about what they’re doing for the environment,” Rhone Resch, SEIA’s chief executive, told the New York Times
. “Now what you’re seeing is it’s a smart investment that they’re making for their shareholders, and this is a standard business practice.”

Small Forage Fish Species
Worth 20 Percent of Global Fisheries
The world’s forage fish species — small, schooling fish such as herring and sardines that play a key role in the food web in marine ecosystems — represent about 20 percent of the global values of all marine fisheries
, according to a new study. In a comprehensive analysis of dozens of food web models from around the planet, scientists from the State University of New York at Stony Brook calculated that these small fish contribute $16.9 billion to global fisheries each year, either as direct catch or as food for larger fish. According to their findings, the direct catch value for forage fish worldwide is $5.6 billion — with the largest market being the Peruvian anchoveta fishery — while the value of fisheries depending on these small fish is about $11.3 billion. “In addition to their value to commercial fishing and other industries that depend on them for their products, forage fish play valuable roles in global ecosystems while they are still in the water,” said Ellen K. Pikitch, co-lead author of the study, published in the journal Fish and Fisheries

Better Use of Fertilizer, Water
Can Feed Growing Population, Study Says
A new study suggests that the the world can meet the surging demand for food in the coming decades without rampant deforestation if farmers make better use of fertilizer and water resources
. In an analysis of management practices and yield data for 17 major crops worldwide, researchers from McGill University in Montreal and the University of Minnesota estimated that yields for most crops can be increased 45 to 70 percent on lands already used for agriculture through more efficient fertilizer application and irrigation. Writing in the journal Nature
, the scientists found that the deployment of best-practice farming could boost global yields of corn, wheat, and rice by 64 percent, 71 percent, and 47 percent
, respectively. In some parts of the world, including the U.S., China, and Western Europe, the study found that far more fertilizer is used than necessary, with much of it ultimately washing into waterways. Through more efficient use of that fertilizer, nutrients could be made available for use in Eastern Europe and Western Africa without adversely affecting communities in the U.S. and China.

India Approves $4 Billion Plan
To Add 6 Million Green Vehicles by 2020
The government of India has approved a 230-billion rupee strategy ($4.13 billion) to spur increased production of electric and hybrid vehicles
over the next eight years, setting a target of 6 million green vehicles by 2020. The new plan, designed to reduce the nation’s reliance on fossil fuels and cut carbon emissions, would attempt to close the gap between the costs of producing green vehicles in India and what consumers can afford to pay. The country’s nascent electric and hybrid car sector slowed dramatically earlier this year when the government removed subsidies of up to 100,000 rupees per vehicle, Reuters reports. According to sources, the new plan would likely include cash subsidies for consumers, increased funding for research and development, and the creation of a charging network, sources said. While specific plans remain to be worked out, S. Sundareshan, the secretary of India’s Heavy Industries ministry, said the government would provide 130 to 140 billion rupees, while private corporations would cover the rest.

Desalination Sector Surges as
Technology Improves, Demand Grows
A new report predicts that global investment in water desalination projects will triple over a five-year period from 2011 to 2016
, driven by improvements in technology and a surge in companies entering the sector. According to Global Water Intelligence, investments in desalination plant installations will grow from $5 billion last year to $8.9 billion this year; by 2016, the report says, the sector could reach $17 billion. A critical factor has been the emergence of technologies that require less energy to make potable water from seawater, including a process called forward osmosis that uses less heat and power than existing reverse osmosis plants and could cut the cost of desalination by as much as 30 percent. Also driving this surge is growing demand in developing nations already facing water shortages, including China and India. “Those huge economies will not be able to step forward without a solution to water scarcity, and one of the solutions is going to be desalination,” Avshalom Felber, CEO of Israel-based IDE Technologies, told Bloomberg News.

Solar Shingles Made from
Common Metals Offer Cheaper Energy Option
U.S. scientists say that emerging photovoltaic technologies will enable the production of solar shingles made from abundantly available elements
rather than rare-earth metals, an innovation that would make solar
energy cheaper and more sustainable. Speaking at the annual meeting of the American Chemical Society, a team of researchers described advances in solar cells made with abundant metals, such as copper and zinc. While the market already offers solar shingles that convert the sun’s energy into electricity, producers typically must use elements that are scarce and expensive, such as indium and gallium. According to Harry A. Atwater, a physicist at the California Institute of Technology, recent tests suggest that materials like zinc phosphide and copper oxide could be capable of producing electricity at prices competitive with coal-fired power plants within two decades. With China accounting for more than 90 percent of the world’s rare-earth supplies, companies and nations are racing to find new sources of rare earth minerals, which are used in everything from solar panels to smart phones.

Process Turns Starbucks’ Waste
Into Ingredients for Consumer Products
A team of scientists is working with the Starbucks coffee chain to develop a bio-refinery process that would convert the company’s discarded coffee grounds and day-old bakery goods into a key ingredient for making plastics and other products. The process, which will be described at a meeting of the American Chemical Society
, builds on existing technology that converts corn, sugar cane, and other plant-based products into the ingredients for biofuels and other consumer products. According to researchers, the process involves blending the bakery waste with a mixture of fungi that breaks down carbohydrates in the food into simple sugars. They are ultimately converted into succinic acid, a material that can be used to make a range of products, including plastics, detergents, and medicines. While most experts say using crops for such purposes would not be sustainable, targeting food waste is an attractive alternative, said Carol S. K. Lin, of the City University of Hong Kong, who was leader of the research team.

Triage System for Plant Species
Devised Based on Geographic Range
With an increasing number of plant species worldwide facing growing threats, from climate change to invasive species, a team of U.S. scientists has developed a process to more rapidly evaluate those plants facing the greatest risks of extinction
. Writing in the journal
Biodiversity and Conservation
, the scientists from the New York Botanical Garden describe a triage method to identify at-risk species based on data from plant research collections and geographic information systems (GIS) technology. According to the scientists, the standard conservation assessment process, developed by the International Union for the Conservation of Nature (IUCN) — which uses a rigorous process to classify species as “extinct,” “least concern,” “endangered,” and “critically endangered” — is limited because it requires large amounts of data that simply do not exist for most species. While there are 300,000 known plant species, they say, only 15,000 species have been evaluated under the IUCN process. As an alternative, they propose a simpler process that classifies species as either “at risk” or “not at risk” based on the key criterion of the size of its geographical range.

Ocean Health Index Evaluates
State of Waters Around the Globe
An international team of researchers has released a new tool that evaluates the state of the world’s oceans
, a so-called Ocean Health Index that its creators say provides the first comprehensive assessment of the relationship
between the planet’s marine regions and human communities. While previous assessments of ocean health were based on the level of “pristineness,” this index is framed in terms of the benefits humans derive from the oceans and the extent to which communities maintain a sustainable marine environment. Using a wide range of criteria — including water quality, marine biodiversity, and the condition of coastal areas — the researchers ranked ocean areas worldwide on a scale from 0 to 100. According to their analysis, published in the journal Nature
, the global ocean received an overall score of 60, while scores for individual areas ranged from 36 to 86. The waters around Jarvis Island, near Hawaii, ranked highest
; the waters off the West African nation of Sierra Leone ranked lowest.

Overuse of Groundwater
Threatens Global Supplies, Study Says
A new study finds that nearly one-quarter of the world’s population lives in regions where water is being used faster than it can be replenished
. Using computer models of global groundwater resources and water use data, scientists from Canada and the Netherlands calculated that the planet’s “groundwater footprint” — the area above ground that relies on water from underground sources — is about 3.5 times larger than the aquifers themselves
. The study found that in most of the world’s major agricultural regions — including the Central Valley in California, the Nile delta region of Egypt, and the Upper Ganges in India and Pakistan— demand exceeds these reservoirs’ capacity for renewal. For example, the groundwater footprint for the Upper Ganges aquifer is more than 50 times the size of aquifer. “This overuse can lead to decreased groundwater availability for both drinking water and growing food,” said Tom Gleeson, a hydrologist at McGill University in Montreal and lead author of the study, published in the journal Nature
. According to the scientists, about 1.7 billion people, mostly in Asia, live in areas where water needs for humans and ecosystem services outstrip the ability of aquifers to replenish themselves.

California Meets 20 Percent
of Electricity Demand With Clean Energy
California power utilities are now achieving more than 20 percent of the state’s electricity needs with renewable energy sources, state regulators say. In its latest quarterly report
, the California Public Utilities Commission (CPUC) said that the state met 20.6 percent of its
electricity demand with renewable sources — including wind, solar, and geothermal — during 2011, up from 17 percent in 2010. In 2012, the report says, the state is on pace to far surpass that level. According to the CPUC report, 2,871 megawatts of energy capacity from clean sources has been added statewide since ambitious clean energy standards were enacted in 2003, and another 3,000 megawatts are expected to be added during 2012. A dozen utility-scale solar photovoltaic plants, with a combined capacity of 2,200 megawatts, are currently being built in California
, while another 62 plants totaling 11,600 megawatts of capacity are being developed. The state’s Renewable Portfolio Standard requires that 20 percent of electricity sold to customers be generated from renewable sources from 2011 to 2013; the target increases to 33 percent by 2020.

U.S. Meat Producers Call for
Pause in Ethanol Quotas in Wake of Drought
U.S. meat, poultry, and dairy producers are urging the Obama administration to suspend a quota for corn-based ethanol production, warning that the renewable fuels standard could trigger a food crisis as a prolonged
drought pushes corn and soybean prices to record levels. In a letter sent to the U.S. Environmental Protection Agency, a coalition that includes the National Cattlemen’s Beef Association and the National Pork Producers Council asked for a one-year waiver on federal ethanol quotas
, saying that the ongoing drought in the U.S. Midwest has slashed the amount of corn available to feed livestock and poultry. The current renewable fuels standard would require that 13.2 billion gallons of corn-based ethanol be produced in 2012 and 13.8 billion gallons in 2013. In 2012, the meat producers say, those quotas would consume nearly 40 percent of all U.S.-produced corn. “The extraordinary and disastrous circumstances created for livestock and poultry producers by the ongoing drought in the heart of our grain growing regions requires that all relevant measures of relief be explored
,” the letter said.

deforestation in the resource-rich nation, a new Greenpeace study says
. Using data and mapping analysis and government information, the group found that about 75 percent of the leased forest land — or about 3.9 million hectares — is controlled by foreign corporations for up to 99 years through a so-called Special Agricultural and Business Leases (SABL) scheme. The report claims that many companies paid government officials to approve long-term leases and that in one case logging companies paid police to intimidate and assault landowners who opposed the leases. “People are losing their land and their livelihoods for up to three generations and their forests forever,” said Paul Winn, leader of the Greenpeace Forests Team. Greenpeace says Papua New Guinea’s logging exports increased 20 percent last year, due largely to the SABL scheme. The total amount of land leased through SABLs makes up 11 percent of the country’s land area
and 16 percent of accessible commercial forest.

`Great Green Fleet’ Trial
Launched by U.S. Navy in the Pacific
The U.S. Navy this week held military exercises in the Pacific Ocean that used an expensive blend of biofuels and conventional fuels to power 71 aircraft and three warships,
part of an ongoing effort by the Navy to develop alternative fuels for its global operations. The so-called “Great Green Fleet” initiative is a top priority of Navy Secretary Ray Maybus, who contends that the U.S. military must eventually free itself from dependence on fossil fuels “because unpredictable and increasingly volatile oil prices could have a direct impact on readiness.” But numerous critics, including U.S. Senator John McCain, criticize Maybus’ initiative as unnecessary and costly, noting that the 50-50 biofuel/conventional fuel blend costs $26 a gallon — more than six times the cost of conventional fuels. A Defense Department study said that the military will spend $2 billion more annually if it continues to pursue its biofuels experiments. About 90 percent of the biofuels was rendered from cooking oil waste and the remaining 10 percent was refined from algae. Maybus, speaking aboard the aircraft carrier USS Nimitz, contended that the rising costs of oil and breakthroughs in biofuel production will eventually narrow the price gap between conventional and alternative fuels.

Aquaculture Output To Rise
33 Percent Over Next Decade, UN Says
The global aquaculture sector could produce 33 percent more fish for human consumption over the next decade
, an increase in production that will help feed a growing world population even as fisheries are overexploited, a new UN report predicts. More than 79 million tons of farmed fish, crustaceans, mollusks and aquatic plants are expected to be produced from 2012 to 2012, a 33 percent growth compared with just a 3 percent growth from capture fisheries, according to the report from the UN’s Food and Agriculture Organization
. By 2018, the amount of fish raised in aquaculture will exceed the amount caught in the wild for the first time and will account for 52 percent of the total by 2021, the report states. This increased reliance on farm-raised fish comes as an increasing number of fisheries worldwide are exploited, with about 30 percent of fish stock now overexploited and another 57 percent fully exploited or very close to maximum sustainable production.
Living Building Challenge Aims to
Revolutionize Green Architecture
In the world of green architecture, no project has more stringent design criteria than the Living Building Challenge
, a rigorous certification system that requires that structures follow 20 design “imperatives” across seven categories, from water and energy use to social

equity and beauty. While the better-known LEED standards pre-certify buildings based on conformance of design specifications with best practices, the Living Building Challenge also judges buildings on actual performance, requiring a documented 12-month occupancy phase. Projects must also prove that they exclude 14 banned materials
, including halogenated flame retardants and PVC plastics, through supplier audits for every product used in construction. Since its inception in 2006,the challenge has fully certified only three buildings
and partially certified two others, raising questions of whether it will have real-world impact. But program director Amanda Sturgeon says the project’s standards are already pushing architecture and design to be more progressive, sustainable, and accountable. “When teams start to ask their suppliers for every ingredient of every product, the message moves up the chain,” she says.

Cities in U.S. Northwest
Adopt Aggressive Recycling Programs
Seattle, San Francisco, and Portland, Ore., have all adopted stringent recycling programs that have generally been embraced by citizens in these progressive cities and have significantly reduced the amount of garbage going to landfills
. The New York Times
reports that Portland has cut the amount of garbage going to landfills by 44 percent by recycling a wide range of materials, including food scraps, and collecting garbage only twice a month. San Francisco, which has adopted even more aggressive recycling initiatives, now reuses 78 percent of what enters its waste stream, compared with the national average of 34 percent. This summer, Seattle is opening a mammoth new waste transfer station that will enable it to sort through and recycle a large portion of its garbage, the Times
reports. With citizens in these relatively small cities — all with populations under 800,000 — pushing for a zero-waste policy, Seattle says that by 2018 it will even provide some neighborhoods with containers to recycle dog and cat waste, turning the excrement into power using anaerobic digests.

Foreign ‘Land Grabs’
Scooping up Key Agricultural Lands
From 2000 to 2010, foreign investors bought or leased roughly 270,000 square miles of prime agricultural land
, most of it in the developing world, according to a report by the Worldwatch Institute. Half of the land was
in Africa, acquired by investors from China, the Middle East, and other countries and regions, Worldwatch said. Although the pace of what Worldwatch called “land grabs” has slowed somewhat in the last several years, private investors and state-owned companies are still buying and leasing land in the developing world to ensure ample food supplies for citizens of land-poor countries.
Worldwatch said the land deals generally took two forms: “South-South regionalism,” in which emerging economies invest in nearby countries, and North-South deals in which wealthy countries with little arable land buy up land in low-income nations. The report said the land deals usually resulted in the displacement of small-scale agriculture for industrial agriculture operations that have more serious environmental impacts.

Rio+20 Summit Ends, With
Little Faith Seen in Government Solutions
Twenty years after the Earth Summit in Rio de Janeiro promised an era of aggressive action on biodiversity loss and global warming, the United Nations Rio+20 sustainability summit ended Friday with recriminations and a growing sense that international institutions will play an increasingly diminished role in solving environmental problems.
World leaders — with the notable absence of the heads of the U.S., U.K, Germany, and Russia — approved an agreement that lacked specifics, commitments, and measurable targets on how to promote sustainable economic development. Numerous conservationists and officials said that cities, local governments, the private sector, and environmental groups will now have to play the key role in fostering sustainable economic growth, slowing climate change, and preserving biodiversity. “The greening of our economies will have to happen without the blessing of world leaders,” said Lasse Gustavson, executive director of the World Wildlife Fund.

A Tepid Agreement
Takes Shape at Rio+20 Summit
World leaders attending the UN’s Rio+20 sustainability summit appear prepared to rubber-stamp an agreement that has been widely criticized
by environmental groups and some government officials as ineffectual. As Chinese Premier Wen Jiabao, Russian President Vladimir Putin, U.S. Secretary of State Hillary Clinton, and other leaders arrived in Rio, participants at the conference seemed resigned to approving an agreement that fails to set concrete goals, timetables, or methods of financing for ensuring environmentally sustainable economic growth, particularly in the developing world. “Let me be frank — our efforts have not lived up to the measure of the challenge,” UN Secretary-General Ban Ki-moon said in opening remarks
. “Nature does not wait. Nature does not negotiate with human beings.” Government officials and diplomats said that the host country, Brazil, was determined to avoid the chaos that surrounded the failed climate talks in Copenhagen in 2009. As a result, delegates from 193 countries drafted a non-committal agreement that heads of state are expected to sign with few changes on Friday.

Major World Cities
Cite Progress in CO2-Reduction Effort
Speaking at the Rio+20 sustainability summit, the mayors of New York City and Rio de Janeiro will announce that 48 of the world’s largest cities are taking steps to cut 248 tons of greenhouse gas emissions by 2020
, the equivalent of removing 44 million cars from the road for a year. New York Mayor Michael Bloomberg and Rio de Janeiro Mayor Eduardo Paes said that four-dozen cities in the C40 Cities Climate Leadership Group
are reducing emissions by launching energy efficiency programs, capturing methane in landfills, installing more efficient street lighting, and other initiatives. They cite the CO2 reductions as proof that cities can make significant progress on slashing greenhouse gases even in the absence of a global agreement on cutting carbon emissions. “We’re not arguing with each other about emissions targets,” Bloomberg told reporters in a teleconference. “What we’re doing is going out and making progress.” Bloomberg and Paes said that 59 cities have committed to cut their carbon emissions by a total of 1 billion tons by 2030, equivalent to the combined greenhouse gas emissions of Canada and Mexico.

Japan Feed-in Tariffs Approved
As Government Restarts 2 Nuclear Plants
Japan’s struggle over its energy future was on display over the last two days as the government okayed restarting operations at two nuclear power plants
while also approving an ambitious renewable energy feed-in tariff
in which utilities will pay a premium for electricity generated by solar, wind, and geothermal power. After shutting down the country’s 50 nuclear power plants following the Fukushima nuclear power meltdown, the government of Prime Minister Yoshihiko Noda on Saturday gave the green light to bring two nuclear reactors in western Japan back online. Despite public unease and a large street protest in Tokyo, the government said that post-Fukushima reforms had rendered the plants safe. Meanwhile, the government approved generous green energy feed-in tariffs as part of a drive to significantly expand renewable power generation.
Under the feed-in tariffs, utilities will pay 42 yen (53 U.S. cents) per kilowatt hour for solar-generated electricity and 23 yen per kilowatt hour for wind-generated electricity.

Sharp Divisions Emerge
As Rio+20 Negotiators Seek Consensus
With the United Nations Rio+20 summit on sustainable development set to open next Wednesday, negotiators from developing nations walked out of a key working group
over disagreements with wealthier nations about funding environmentally responsible development and the transfer of green technology. As negotiators attempted to forge an agreement, the G77 bloc of developing nations, led by China, proposed that wealthy countries finance a global fund for sustainable development with an initial annual budget of $30 billion. But European Union nations said they were unable to afford that because most EU states faced an economic crisis. Luiz Alberto Figueiredo, of the Brazilian Foreign Ministry, rejected that argument, saying, “We cannot be held hostage to the retraction resulting from financial crises in rich countries.” As 130 world leaders (with the notable absence of the leaders of the U.S., Britain, and Germany) prepared to arrive, a top Brazilian diplomat lamented the summit’s disparate blocs
, saying the traditional north-south divide was only one of many divisions.

Environmental Tipping Point
Is Nearing, International Study Says
The rapid warming of the planet, a soaring human population, the steady loss of biodiversity, over-exploitation of energy resources, and the degradation of the world’s oceans are driving the world toward an ecological tipping point,
according to a new study in Nature
. Twenty-two scientists from five nations compared the major changes taking place today with previous ecological shifts — such as the end of the last Ice Age 14,000 to 18,000 years ago — that triggered mass extinctions of some species, expansions of others, and the creation of new global ecosystems. The paper said that while there is still considerable uncertainty as to whether the world is now approaching such a “state shift,” many signs point to a future of ecological upheaval. “Given all the pressures we are putting on the world, if we do nothing different, I believe we are looking at a time scale of a century or even a few decades for a tipping point to arrive,” lead author Anthony Barnosky
, a biologist at the University of California, Berkeley, said in an interview.

Japan Forced to Reconsider
Climate Targets Without Nuclear Power
Japanese officials say they may have to scrap long-term targets for carbon emissions reductions as a consequence of moving away from nuclear power in the aftermath of last year’s Fukushima disaster. According to the Japan Times
, government officials this week conceded that goals to cut carbon emissions 25 percent by 2020 compared with 1990 levels were “to a fair degree” predicated on the use of nuclear power. “I have no doubt that an overall review will be necessary,” deputy Prime Minister Katsuya Okada said. Last month the nation shut down its last working nuclear plant more than a year after the Fukushima disaster made nuclear power unacceptable to many Japanese residents
. But considering that nuclear power provided nearly 30 percent of the nation’s electricity before the 2011 disaster, many predict the idled nuclear plants will trigger a rise in greenhouse gas emissions from an increased use of fossil fuels. A report released earlier this week said that the combined electricity produced from natural gas, oil, and coal-powered plants from January to April was up 40 percent
compared with the same period in 2011.
