262kg of trash removed from Changi Beach Park

S Ramesh, Channel NewsAsia 19 Sep 09;

SINGAPORE: More than 260 kilogrammes of trash were removed from Changi Beach Park on Saturday morning.

Over 100 volunteers picked their way through the 300-metre shoreline on Changi beach in the annual Ocean Conservancy's International Coastal Cleanup exercise.

Among the 262kg rubbish were styrofoam boxes, plastic bags and cigarette butts.

Last year, more than 200kg of trash comprising beverage bottles and cans, plastic bags and barrels were removed from the Lim Chu Kang Beach.

Data collected from the coastal cleanup will be sent to Ocean Conservancy for analysis.

Research results from the Washington DC-based institute have been influential in governments' formulation of environmental policies including those in Singapore.

One such initiative is the "Bring Your Own Plastic Bag" programme, which is said to be the result of the awareness generated by the coastal cleanup efforts.

Kelantan is largest birds' nests producer

New Straits Times 16 Sep 09;

KOTA BARU: Unlike most other states, breeding swiftlets for birds' nests is licensed by the state authorities in Kelantan.

The state has become one of the largest producers of birds' nests in the country.

The centre of the industry lies here and in Kuala Krai and Tumpat. And a purpose-built township for rearing swiftlets is planned in Jalan Pantai Cahaya Bulan soon.

The annual licensing fee for a swiftlet building is RM1,000 for the first floor, and RM500 each for subsequent storeys.


Unlike most breeders, Ooi Siong Hwa has chosen not to breed swiftlets in town. He has built a breeding structure in the middle of a padi field in Tumpat.

He says that though the initial investment was high -- RM300,000 -- he expects excellent returns.

A kilogramme of high quality birds' nests fetches about RM7,000. Most are exported to Hong Kong and China.

Birds' nests have been used in Chinese cuisine for over 400 years, and are believed to have medicinal value.

Russia's Putin brings leopards back to Caucasus

Gleb Bryanski, Reuters 19 Sep 09;

SOCHI, Russia (Reuters) - Russian Prime Minister Vladimir Putin released two leopards into the wild Saturday in a bid to revive the fortunes of the rare cats in the Caucasus and soothe ecological worries over 2014 Sochi Games.

Caucasian or Persian leopards disappeared from the Caucasus in the 1920s due to excessive hunting. Turkmen President Kurbanguly Berdymukhamedov sent two male leopards caught in Turkmenistan by plane to Sochi. Female leopards are to follow.

"We are standing here and admiring your animals. Glorious animals, very beautiful," Putin, surrounded by International Olympic Committee members, told Berdymukhamedov by telephone as he stood by the cage in the Sochi national park.

Russia won the right to host 2014 Winter Olympic Games in Sochi and major construction works are about to begin.

Critics say huge construction projects may harm the environment. They question the need for spending billions of dollars on the games during a financial crisis and say they do not believe all the infrastructure would be ready by 2014.

"I think Russia is on its way to organizing an exceptional Olympic Games," French Alpine skiing legend and IOC member Jean-Claude Killy told reporters.

Russia's most popular politician, Putin, enjoys a tough guy image, being photographed riding bare-chested on horse back, fishing in Siberia or saving tigers in Russia's Far East.

Saturday, Putin stared in silence at one of the leopards, which initially refused to abandon his traveling cage, visibly stressed after its long journey.

"Good boy," Putin said as the cat snarled at him and jumped out while guards and reporters pulled back. "We have found common language, they understand me," said Putin.

The leopards will gradually move to a larger fenced area of the park before they are released into the wild. Scientists plan to bring female leopards at a later stage and hope some 30-50 cats will be living around Sochi in six years.

Flying Turkmen leopards to bring species back to Caucasus
WWF 23 Sep 09;

Sochi, Russia: Two leopards from Ashkhabad, Turkmenistan are recovering after a long flight and car ride to their new homes in a Russian national park, as part of efforts to reintroduce the species into the Caucasus region.

The leopards were moved into spacious pens in Sochi National Park in southwestern Russia as part of a species reintroduction programme implemented by WWF and the Russian government.

They travelled more than 1,000 kilometers by plane and then by car, and are in good health despite the long trip and being put under anesthesia.

Upon arrival, the leopards were met by WWF, park staff and Russian Prime Minister Vladimir Putin in Sochi on Saturday and then released into large pens inside a special center created for them in the park.

The big cats (Panthera pardus saxicolor) will take part in the Programme for Persian Leopard Reintroduction, developed by experts from WWF and the Russian Academy of Natural Sciences, and approved by the Russian Ministry of Natural Resources and Ecology.

“There are very few leopards in the whole of Caucasus, only a few dozen,” said Igor Chestin, WWF-Russia CEO. “They exist with the help of some inflow from Iran, which has several hundreds remaining. We want to create a new, Northern-based nucleus of the population, so that together with the Southern nucleus in Iran it can guarantee sustainability for the leopard population both in the Russian Caucasus and neighboring countries.”

The Leopards are already actively moving around. They drink a lot of water, which is normal after anesthesia, and one of them on Sunday ate a slab of meat given to him by veterinarians. Both leopards are males.

“They will have time to adapt to the new conditions and start to feel ownership of the territory by the time females arrive ”, said Umar Semyonov, deputy director of the Sochi national park. “And it will be easier for females to adapt with support from males.”

The leopards from Turkmenistan will live in the Centre for breeding and rehabilitation in the Sochi national park. Only their descendants will be released into the wild in the Caucasus strict nature reserve.

“Areas for future release were carefully chosen to resemble as much as possible leopards’ habitat in Turkmenistan, both in terms of relief and prey,” said Professor Anatoly Kudaktin, programme scientific supervisor. “Conditions in the Caucasus will be even more comfortable in some ways than in Turkmenistan, and ungulate density is higher here.”

These types of leopards are endangered because most of their habitats were lost in the last century due to transformation and migration routes between remaining isolated populations are cut off due to infrastructure development, which has led to small fragmented populations that cannot easily breed.

Financially, the Programme is supported by WWF-Russia, “Rosa Khutor” Company, VympelCom Group, and Russian government.

'Eco-xenophobia' on the rise in the UK warns conservationist

The campaign to eliminate alien species like grey squirrels and rhodendrons from Britain is a form of "eco-xenophobia", according to a leading conservationist, who claims native plants and animals are doing just as much damage.

Louise Gray, The Telegraph 19 Sep 09;

An increasing amount of conservation resources in Britain is focused on getting rid of "alien species" like grey squirrels or even parakeets.

However Ian Rotherham, Director of the Environmental Change Research Unit at Sheffield Hallam University, said these species sometimes attract undue attention simply because they are seen as foreign invaders.

On the other hand, native species that also causing problems are often ignored.

The eradication of Japanese knotweed has received millions of pounds worth of funding from the Government while the buddleia or "butterfly bush" and native clematis, also known as old man's beard, can also be damaging but receive little funding. Similarly bracken, hawthorn or blackthorn destroy heaths and moors where many endangered animals live but escape the attention of most conservation groups.

Much loved animals like the badger is spreading disease among cattle and even red squirrels damage trees. But it is the "alien" grey squirrels and muntjac deer, that are loved by people in cities, that are facing the cull.

Dr Rotherham said the Government and conservationists need to focus on "problem" species rather than alien species in future in order to improve the landscape.

In addition the contribution made to the economy by non-native species should not be overlooked, he said. For example rhododendron, alongside other "exotic" species like Corsican pine are a major part of historic landscaped gardens as well as providing shelter for breeding nightingales and otters.

He even feared the policy of getting rid of "alien invaders" was in danger of being abused by racist groups.

"I’ve coined the term ‘Eco-xenophobia’ to stress the idea that we are making judgements not through objectively supported science but through mistaken ideas of what is native, what is alien, and hence what is good or bad," he said. "Many of these ideas and concepts are very recent and disguise real and serious issues of problem species and of sustainable land management and custodianship. What’s worse perhaps, is that they resonate with ideas growing with the BNP in the UK, and with other right wing groups across Europe."

A spokesman for the Department for the Environment said: "Whilst the introduction of species over thousands of years has shaped British wildlife and the countryside, where they become invasive they can have a serious impact on native wildlife and cost the British economy at least £2billion a year.

“The non-native species strategy announced last year is designed to identify and deal with problem species in order to protect British wildlife for the future.”

U.S. Great Lakes toxic cleanups lagging badly

John Flesher, Associated Press Yahoo News 15 Sep 09;

TRAVERSE CITY, Mich. – Cleanup of the most polluted sites in the Great Lakes is moving so slowly it will take 77 more years to finish the job at the existing pace, according to a federal report.

The U.S. Environmental Protection Agency still does not know the full extent of the problem even though the highly contaminated spots were identified two decades ago, said the report by the agency's inspector general.

"Without improved management, coordination and accountability, EPA will not succeed in achieving the results intended" for the recovery program, said the report, issued Monday.

Toxic sediment cleanup is among the goals of a $20 billion Great Lakes restoration plan developed by government agencies and nonprofit groups in 2005.

President Barack Obama has pledged $5 billion toward carrying out the plan and requested $475 million in his 2010 budget. Roughly one-fourth of that amount would be devoted to the cleanups.

The plan estimates the total cleanup price at $2.25 billion in federal money, with state and local governments kicking in an additional $1.2 billion.

The inspector general's report analyzes the government's handling of Great Lakes "areas of concern" — rivers, harbors and other locations where bottomlands are laced with toxic chemicals such as mercury, PCBs and heavy metal wastes.

Forty-three of the areas were identified in the late 1980s, including 26 within U.S. territory; 12 entirely within Canada; and five that straddle the border. Only two Canadian sites and one in the U.S. — the Oswego River in New York — have been fixed and dropped from the list.

The areas range from less than 1 square mile to hundreds of square miles. Because of their location near river mouths and harbors that flow into the Great Lakes, they are considered a leading source of pollution systemwide.

Between them, they have 68 sites believed to contain more than 76 million cubic yards of contaminated sediments, according to state officials. But the report says accurate estimates have not been developed for more than 30 percent of the cleanup sites.

The EPA's Great Lakes National Program Office works with states and local communities in developing restoration plans.

The report says the program has had some successes, particularly since Congress enacted the Great Lakes Legacy Act in 2002 to provide a stable funding source. But it says the EPA has yet to establish a suitable framework for managing the cleanups, which often involve numerous offices responsible for carrying out laws.

"In the absence of coordinated planning, costs can escalate, resources are wasted, and risks to human health and the environment increase due to delays in site cleanups," it says.

Calls seeking comment were left with EPA officials.

Sen. Carl Levin, D-Mich., a longtime supporter of the cleanup initiative, said the EPA's performance had improved since the legacy act was approved.

"Before that, they only had funding for planning for sediment cleanup," Levin said Tuesday.

The report also shows the importance of accountability as Congress ramps up federal spending on the lakes, said Joel Brammeier, acting president of the Chicago-based Alliance for the Great Lakes.

"We've got to have mechanisms in place so that when we go back for more money, we'll be able to tell Congress what a great job we did spending the money they've already given us," Brammeier said.

Biofuel Production Could Undercut Efforts To Shrink Gulf 'Dead Zone'

ScienceDaily 16 Sep 09;

Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. The zone, which reached the size of Massachusetts in 2008, forms in summer and threatens marine life and jobs in the region.

Their study is scheduled for the Oct. 1 issue of ACS' semi-monthly journal Environmental Science & Technology.

Christine Costello and W. Michael Griffin and colleagues explain that the zone forms when fertilizers wash off farm fields throughout the Mississippi River basin and into the Gulf of Mexico. The fertilizers cause the growth of algae, which eventually depletes oxygen in the water and kills marine life. Government officials hope to reduce fertilizer runoff and shrink the zone to the size of Delaware by 2015. But that goal could be more difficult to reach due to federally-mandated efforts to increase annual biofuel production to 36 billion gallons by 2022, the study says.

The scientists studied the potential effects of increased biofuel production on the "dead zone," with a life-cycle analysis of nitrate fertilizer use on biofuel crops such as corn, soy, switch grass and stover (corn stems and leaves). They conclude that meeting the biofuel production goals will likely increase the depletion of oxygen compared to current levels in the Gulf due to more nutrient runoff.

Geothermal power quakes find defenders

Shanta Barley, New Scientist 16 Sep 09;

Geothermal energy is in the dock in Germany, but some scientists are pleading for leniency.

A government panel is investigating claims by the geological survey for the state of Rhineland-Palatinate that a geothermal plant triggered a magnitude-2.7 earthquake on 15 August in the town of Landau in the state. If the panel finds against the company that built the plant, Geo X of Landau, it could be shut down.

Geothermal plants work by pumping water into hot rocks several kilometres down, forcing small cracks in the rock to expand. Steam escapes through the cracks to the surface, where it drives a turbine, producing clean energy. But critics say the process increases the risk of earthquakes.

"Any process that injects pressurised water at depth into rocks will cause them to fracture and possibly trigger earthquakes," says Brian Baptie, an earthquake specialist at the British Geological Society.
Whose fault is it?

Engineers rather than technology must take some of the blame, says Roy Baria, a geophysicist on the panel reviewing the Landau quake, who also works for geothermal energy company EGS Energy, based in Penzance, UK . Past quakes triggered by plants in Basel, Switzerland, were avoidable, he says. "The engineers failed to adhere to best-practice guidelines."

Even the worst geothermal earthquakes have failed to topple a building or kill a human, says Ernest Majer, a seismologist at the Lawrence Berkeley National Laboratory in California, pointing out that geothermal power isn't the only industry that triggers earthquakes.

"Any industry which injects high-pressure fluid into rock, and that includes the oil, nuclear and carbon sequestration projects, has the potential to cause tremors," he says.

EU plans 30 cities to lead world on "smart" energy

Pete Harrison, Reuters 16 Sep 09;

BRUSSELS (Reuters) - Europe will select 30 cities to pioneer "smart" electricity grids and space-proven insulation as it seeks to lead the global race for green technology, a draft European Union document shows.

The windpower sector must shift offshore and strive to provide a fifth of EU electricity by 2020 -- ahead of industry goals -- said a draft of the European Commission's long-awaited Strategic Energy Technology Plan.

The so-called SET-Plan lays out the EU's strategy for promoting hi-tech solutions to climate change to give European businesses a head start as the world switches to low-carbon energy.

Billions of euros will have to be poured into research to avoid falling behind the United States, which is pouring $777 million into energy research, the draft, obtained by Reuters ahead of the plan's release next month, said.

"Basic research is chronically underfunded in the EU," the report said. "We need to stimulate and incentivize our best brains to push back the frontiers of science."

The project envisages 25 to 30 "smart cities" -- highly insulated cities that glean energy from their waste and the sun and wind overhead and channel it down to the electric cars, trams and buses in the streets below.

"These Smart Cities will be the nuclei from which smart networks, a new generation of buildings and alternative transport means will develop into European wide realities," it added.

EU officials are still calculating the exact needs for funding and how it will be split between industry and the public purse.

MIXED REACTION

Environmentalists gave the plan a mixed reception, saying it should have completely ditched coal power and nuclear.

The geothermal industry, which generates steady "baseload" power by tapping into the earth's natural heat, said it provided the perfect complement to fluctuating wind and solar and expressed dismay it had been ignored altogether.

"A renewable energy mix can not be reached in the future without geothermal energy," the European Geothermal Energy Council said.

Boosting energy efficiency will top the agenda, an area where the European Space Agency is expected to contribute.

"This could be achieved by transferring advanced insulation materials and ultra-efficient energy systems to the terrestrial energy sector," the report said.

Coal-fired power stations will be pushed to trap and bury their carbon dioxide emissions and the nuclear industry will be urged to move toward a new generation of reactors -- the so-called Generation-IV reactor.

"Such reactors will be able to exploit the full energetic potential of uranium, thus greatly extending resource availability by factors up to 100 over current technologies," said the report.

Greenpeace campaigner Frauke Thies said the overall message was inconsistent, as money poured into coal and nuclear would only prolong Europe's unhealthy dependence on an inflexible, centralized energy network.

"We must focus on building a decentralized and flexible energy system that can handle fluctuations in renewable energy and balance supply and demand," she added.

FACTBOX: EU seeks to take lead in green energy research
Reuters 16 Sep 09;

BRUSSELS (Reuters) - The European Union's executive will next month publish its strategy for promoting hi-tech solutions to climate change, aiming to give European businesses a head start as the world switches to low-carbon energy.

A draft document obtained by Reuters gives insight into the European Commission's priorities.

Billions of euros will be needed and thousands of jobs created, but officials are still calculating the exact figures and what proportion of spending will come from the public purse or from industry.

WIND ENERGY

The windpower industry must reduce costs faster and build more wind farms offshore where the wind is more reliable and planning constraints are smaller, the report says.

To deal with the tough marine environment, turbines will have to become more powerful and resilient, with new types of substructure to support them.

This will require up to 10 new testing facilities for turbine components, up to 10 demonstration projects of next generation turbines and at least 5 prototypes of offshore substructures.

The goal is fully competitive wind power capable of contributing up to 20 percent of EU electricity by 2020 and a third by 2030.

SOLAR POWER

The photovoltaic sector must reduce costs and enhance performance and lifetime. It must automate and speed up manufacturing. New, visually appealing concepts for integrating photovoltaic systems into the urban fabric need to be developed.

This will require up to 5 pilot plants for automated photovoltaic mass production and several demonstration projects for both decentralized and centralized power production.

The concentrated solar power sector must reduce costs, improve system efficiency, develop storage systems and reduce water consumption. Up to 10 large "first of a kind" power plants must be built.

The programme envisages that up to 15 percent of EU electricity could be generated by solar power in 2020.

POWER GRID

The focus will be on building "smart grids" that can balance the fluctuating supply of electricity from renewable energy sources with fluctuating consumption by EU citizens. Up to 20 real-life scale demonstration projects will be needed.

The goal is that by 2020, half of networks in Europe would allow the seamless integration of renewable energy.

SMART CITIES

Smart cities will glean renewable energy from the sun and wind and from their own waste, feeding it into the electricity network and to trams and cars in the street.

Between 25 and 30 pioneer cities will transform their buildings, energy networks and transport systems.

BIOENERGY

The bioenergy sector must demonstrate its technology at greater scale, from pilot plants to full industrial scale.

Up to 30 such plants will be needed across Europe to take full account of differing geographical and climate conditions and logistical constraints.

By 2020, the contribution to the EU energy mix from cost-competitive, sustainable bioenergy could be at least 14 percent.

CLEAN COAL

The European Union has laid out plans to have 12 Carbon Capture and Storage (CCS) pilot plants up and running by 2015.

The target is to reduce the cost of CCS to 30-50 euros per tonne of carbon dioxide (CO2) captured by 2020, making it cost-effective within a carbon pricing environment.

NUCLEAR

The industry will have to move toward a new generation of reactor type -- the so-called Generation-IV nuclear reactor.

Commercial deployment of Generation-IV reactors is foreseen for 2040, but to achieve that target, work has to start now. Solutions for nuclear waste must be identified.

FUEL CELLS AND HYDROGEN

About 470 million euros ($690 million) has already been earmarked for developing fuel cells and hydrogen-powered vehicles during 2008-2013 -- to be matched by industry contributions.

Larger scale demonstrations and infrastructure will be needed, plus more research funding.

Scientists Take To The Trees To Measure Global Warming

Sharon Reich, PlanetArk 17 Sep 09;

GIFFORD PINCHOT NATIONAL FOREST - Gliding across the treetops in the Gifford Pinchot National Forest in Washington State may sound like the latest trend in eco-tourism.

But the gondola on the massive Wind River crane is not used for recreational sport -- it's a research tool being used by scientists at the University of Washington to measure the effects of global warming on trees.

For years researchers have been studying trees' ability to absorb carbon dioxide, one of the major greenhouse gases responsible for global warming, but from the ground they've only been able to get half the picture.

Matt Schrader, a University of Washington researcher, said tree tops have been the hardest for scientists to access, yet are considered the most important to examine the health of trees.

"It's the crown ... that's where the tree is actively responding to the environment," Schrader told Reuters TV.

"That's where the tree interacts with other plants and animals and so accessing the crown safely and being able to do it often is important."

A US Geological Survey-led study published in January said tree death rates have more than doubled over the past five decades in the western United States.

Scientists said the increase in mortality will have profound affects on the size of trees and the density of forests.

Schrader said this forest is the perfect location to measure the effects of global warming on trees because it is one of the oldest and densest in the United States, and contains hundreds of years worth of data.

"So being up here at the branch level in the canopy we're able to see these subtle changes that occur from year-to-year and you just wouldn't be able to do that from the ground staring up with binoculars," said Schrader from his man-made aerie.

The Wind River crane measures 285 ft tall and has a jib arm that reaches out 279 ft over the top canopy layer of the forest.

Throughout the forest, sensors are set up to measure different variables that can impact the trees.

The jib is outfitted with an ultrasonic anemometer, which measures wind speed and direction in three dimensions. An ultra-sensitive intake tube draws in air samples, measuring how much carbon dioxide is present in samples of air.

Other sensors that help the researchers determine whether or not carbon dioxide, CO2, is being drawn into the forest, or being released into the atmosphere, include temperature and relative humidity monitors. To get a complete picture of actual carbon levels, CO2 is also measured at the trees' roots.

Dr. Ken Bible, the site director at the Wind River Canopy Crane Research Facility, said the crane and sensors amount to having a "controlled experiment on planet Earth."

"If it's continuous and automated no matter what pattern is going on naturally in the forest you're going to capture it," he said.

In the past, researchers assessed tree growth and yield on a five year basis but by monitoring the sensor data and the needles at the tops of tree branches, Bible and his team can make observations about the flow of carbon dioxide every 30 minutes.

With the ability to conduct long-term studies in forests like this one, whose massive trees can store up to 600 tonnes of carbon per hectare, scientists hope to be able to tell a more complete story about the mortality rate of trees, leaving researchers better equipped to manage global warming.

No Leader on Climate Change as Nations Prepare to Meet

Neil MacFarquhar, The New York Times 19 Sep 09;

UNITED NATIONS — Economists point to powerhouse countries like India to illustrate the hurdles facing some 100 world leaders due to gather in New York this Tuesday for the highest level summit meeting on climate change ever convened.

The Indian government has announced a major commitment to solar power as a renewable means of bringing electricity to more than 400 million people now living without it. Yet the government was pilloried at home last summer for accepting the international goal of preventing a global temperature rise of more than 2 degrees Celsius (3.6 degrees Fahrenheit) by limiting emissions. Opposition parties accused it of selling out the country’s future development.

While virtually all of the largest developed and developing nations have made domestic commitments toward creating more efficient, renewable sources of energy to cut emissions, none want to take the lead in fighting for significant international emissions reduction targets, lest they be accused at home of selling out future jobs and economic growth.

The negotiations for a new climate change agreement to be signed in Copenhagen in December are badly stalled. With the agreement running more than 200 pages — including what negotiators estimate are a couple of thousand brackets denoting points of differences — diplomats and negotiators fear that the document is too unwieldy to garner a consensus in the coming months.

In convening the meeting, the United Nations is hoping that collectively the leaders can summon the will to overcome narrow national interests and give the negotiators the marching orders needed to cut at least the outline of a deal.

“I have been urging them to speak and to act as global leaders; just go beyond their national boundaries,” Ban Ki-moon, the United Nations secretary general, said Thursday.

On Tuesday, the leaders, including the heads of state or government of most economic powers, are to engage in a series of round-table discussions on outstanding climate change issues that will be less like negotiations than a series of college seminars designed to forge political momentum.

“They won’t do it one by one,” said Robert Orr, the United Nations assistant secretary general for policy planning. “Politically, they all have to jump together, and this is the essence of this summit. We will see if any governments are ready to say, ‘I am stepping through the door now; are you going to come with me?’ That would be a huge break.”

Senior organizers said they had never been involved in such a high-level summit meeting where the outcome was not predetermined. Fundamentally, although limiting the temperature rise to 3.6 degrees Fahrenheit is an accepted goal, there is no consensus on how to get there.

The industrialized nations have not agreed on midterm targets. They have made pledges of roughly half the target set by the Intergovernmental Panel on Climate Change, a 25 percent to 40 percent reduction from 1990 levels by 2020.

Developing countries have agreed on the need to mitigate their emissions, but have rejected any mandatory limit, and they demand financial and technical support in exchange.

The issue of aid for the poorest countries to adapt to the impact of climate change has been shunted aside. Finally, there is no agreement on what institutions would verify that targets are being met and supervise the finances.

“The mood in the negotiations has been that I should do as little as possible as late as possible and let the other person go first,” said Kim Carstensen, the director of the Global Climate Initiative of the World Wildlife Fund.

In recent weeks, sharp divisions have emerged between the United States and the European Union. The Europeans announced that they would donate $2 billion to $15 billion a year for the next decade to help less developed nations adapt to climate change. The Obama administration has not offered anything close.

The Europeans also want binding, near-term targets for developed nations, a legacy of the last significant global climate accord, the 1997 Kyoto Protocol, which the Bush administration rejected because it did not set limits on emissions from China and other major developing nations.

The European target is a 20 percent reduction of 1990 levels by 2020, still less than the 25 percent recommended by the Intergovernmental Panel, although the Europeans said they would accept 30 percent if everyone agreed.

The American position is that any targets be enforced by domestic laws rather than international treaties, that they be verifiable and distributed equally. A House bill approaches the European target, but the Senate is expected to dilute it.

But the chances of a final bill’s clearing Congress by December are increasingly unlikely, so experts are eagerly waiting to hear what President Obama, who made climate change a key issue in his administration, proposes in his speech on Tuesday.

A speech by President Hu Jintao of China is also widely anticipated, with experts hoping he will announce a significant commitment to renewable energy and emissions reductions in China’s next five-year plan. Mr. Hu is the first Chinese president ever to attend the annual United Nations General Assembly, where leaders will convene Wednesday.

Between them, the United States and China account for about 40 percent of world emissions, split almost evenly, so if the two reach a consensus it will also provide significant impetus for a global agreement.

The United States also suffers from the “after you” syndrome, with some Congressional leaders demanding that China agree to reductions before the United States agrees to an overall framework, a formula that experts warn will kill progress.

“We don’t want to get hung up on trying to say that the U.S. and China will reduce the same percentage or the same amount,” said Timothy E. Wirth, the president of the United Nations Foundation and a former Colorado senator who has long been involved in climate negotiations. “Those numbers can drag us right down.”

Blocs of smaller, poorer nations have their own agendas. The island countries of the Pacific and the Caribbean will be pushing for an even lower temperature ceiling — 1.5 degrees Celsius — because they fear that the rising seas caused by even a 2-degree rise would drown or severely damage them. The Africans are threatening to walk out of the negotiations if they are not promised $300 billion in aid.

New Zealand objects to the fact that the negotiations have basically ignored agriculture, which accounts for 13 percent to 14 percent of greenhouse gases. Developing nations fear that any regulation of agriculture could deepen the severe problems in feeding their populations.

Such issues, while parochial, may be no less important in building an agreement that works across the world’s political borders.

“The instinct is a kind of nationalist response that can get it exactly backwards,” said Jeffrey Sachs, director of the Earth Institute at Columbia University. “We should be viewing this as global problem solving, not as global negotiation.”
