The six-party agreement reached last week in Beijing to cap North Korea's nuclear program was a triumph for diplomacy. But contrary to much of the conventional wisdom in recent days, the fruits of the victory fall mostly to the North Koreans.

In the short term, the deal will halt the country's production of nuclear materials, limiting its ability to expand a nuclear arsenal tested in October. But for this concession, the North Koreans get to keep that arsenal intact, at least for now, and stand to make significant economic and political gains in relations with the United States, China and South Korea.

Some critics say the Beijing agreement is a lesser version of "the Agreed Framework" reached in 1994 by the Clinton administration, later cast aside by President Bush. Former Clinton-era Defense Secretary William Perry, speaking Tuesday at the Asia Society, characterized the new agreement as "thin gruel," while backing it as "a small but a very important step forward."

The ultimate judgment will await the uncertain implementation of numerous crucial, but still vaguely defined, steps down the road. The North Koreans are certain to exploit every ambiguity in the text and to drag out the phase that calls for actual dismantlement of their nuclear program and weapons.

Unfortunately, the process that led to this moment suggests that this will not go well. Contrary to the administration's version of events, Pyongyang was not dragged to this deal by pressure -- not from Washington and not from North Korea's angry patrons in Beijing.

"We don't have the North Koreans on the ropes," a former senior U.S. intelligence analyst who has watched that closeted country for decades said. "We don't have them on the run."

On the contrary, there is ample evidence that this agreement is yet another demonstration of North Korea's uniquely successful brand of negotiation via escalation: a use of brinkmanship and willingness to go up to and over the line that converts weakness into leverage.

Against that approach, the Bush administration's preference for using tools of coercion and threat, even of pre-emptive war, failed. If anything, it brought about the very opposite outcome than the United States envisioned: it encouraged North Korea to move even more rapidly to develop and test a nuclear weapon.

The pattern of brinkmanship was already clear during the Clinton years -- what Korea expert Scott Snyder famously termed "negotiating on the edge." When confronted, Snyder noted, the North Koreans typically responded by accelerating the crisis, unworried by the consequences. The fear of appearing weak has underlined all North Korean behavior.

The Bush administration came into office almost seeking a confrontation, as the president and many of his advisers were convinced the 1994 deal was fatally flawed. Ironically, the North Koreans thought they were on the verge of strategic breakthrough, after a deal to halt missile tests and preparations for President Clinton to visit Pyongyang in the final weeks of his administration. An improved relationship with the United States would balance the power of its Chinese patron, whom North Korea deeply distrusts, and give it legitimacy in an ongoing struggle with South Korea for leadership on the Korean peninsula.

Instead Bush froze the Clinton framework and sought a new, tougher approach. In January 2002, Bush delivered his famous State of the Union depiction of North Korea as a member of the "axis of evil," along with Iran and Iraq. That October, U.S. negotiators confronted Pyongyang with accusations of cheating by pursuing a clandestine uranium-enrichment program.

The 1994 agreement collapsed amid a tit-for-tat series of escalatory moves -- beginning with a U.S. cutoff of heavy fuel oil and leading to North Korea ousting international inspectors, withdrawing from the Nuclear Non-proliferation Treaty and restarting its reactor and recycling facility to produce plutonium. Bush vowed that the United States would not "be blackmailed."

Meanwhile, preparations for war in Iraq were mounting. The Bush administration was convinced the awesome display of U.S. power would successfully intimidate the other two points on the axis of evil, North Korea and Iran.

"We are hopeful," then senior State Department official John Bolton dryly said as the invasion came to a close, "that a number of regimes will draw the appropriate lesson from Iraq -- that the pursuit of weapons of mass destruction is not in their interest."

American threat

The North Korean officials drew an entirely different conclusion: they could not afford to seem weak in the face of what they perceived as an American threat to terminate their regime.

"Only tremendous military deterrent force powerful enough to decisively beat back an attack supported by ultra-modern weapons can avert a war and protect the security of the country," said an official statement issued April 6. "This is the lesson drawn from the Iraqi war."

A drawn-out process of negotiations began later that month, beginning with a three-way meeting in China and moving that summer to six-party talks that also included South Korea, Japan and Russia. The U.S. position was to deny Pyongyang what it wanted most -- direct talks with Washington -- and to demand verified dismantlement of its nuclear program, on the model of Libya, before any rewards, economic or political, were provided.

As the war in Iraq wore on, and the threat of military force became less credible, the administration looked for other coercive tools. It forged a multinational agreement to intercept suspicious cargoes and launched a crackdown on illicit North Korea trafficking in drugs and counterfeit currency and goods, which are believed to be the main source of support for the regime's elite.

The North Koreans countered with their own demands, offering a plan to freeze their nuclear program, with compensation, followed by a coordinated series of reciprocal steps leading toward eliminating the program. Their offers were accompanied by statements that they already had the bomb and were prepared to test it.

When the Bush administration started its second term in 2005, it attempted to escalate pressure -- this time with charges that North Korea was exporting nuclear materials to the Middle East and calls for China to put pressure on its difficult clients. Pyongyang moved to unload a second set of spent fuel from its reactor and reprocess it -- American experts believe North Korea created six to eight bombs worth of plutonium after 2002.

Agreement sours

A return to the bargaining table in September 2005 yielded an agreement on the principles that would underlie a denuclearization of the Korean peninsula. But that sign of progress disappeared within hours as both sides sparred over the meaning of a pledge to build nuclear power reactors for North Korea as compensation for it dismantling its nuclear weapons.

The imposition of measures to curb the flow of North Korean "illicit" money through Chinese and other banks added to the acrimony. Administration officials described this as a legal issue driven by Treasury Department efforts to curb counterfeiting. But as Bush admitted recently, it was used as leverage in the nuclear talks.

Throughout the past year, Bush administration officials expressed confidence that these measures were causing serious pain to the North Korean leadership. Some even talked boldly of "turning out the lights" in Pyongyang through such sanctions.

But Pyongyang could read the news from Iraq as well as any American voter. Instead of having its lights turned out, North Koreans put up their own light shows. On July 4, a date chosen with apparent intent, they carried out a test of a battery of ballistic missiles, in defiance of warnings, including one from China. A U.N. resolution condemning the action -- and other steps, including a South Korean suspension of food and fertilizer aid and Chinese attempts to slow trade -- followed.

In October, again in defiance of pressure from all fronts, the North Koreans tested a nuclear device. This prompted another U.N. resolution, backed by China, to impose limited economic sanctions. But although China was clearly angered, there is little evidence it moved to cut off the lifeline of trade, particularly energy supplies.

North Korea's willingness to cross what everyone believed was a "red line" changed the equation permanently. It allowed Pyongyang to return to the six-party talks, stalled for more than a year, but now from a position of strength. At the meeting in December, the North Koreans refused to discuss any other issues unless the U.S. financial sanctions were removed. North Korean officials hinted of preparations for a second test.

The United States blinked, agreeing to hold long-sought direct talks, held in Berlin in mid-January. The talks yielded the outlines of the Beijing deal but also a separate U.S. concession to lift the financial measures within 30 days of signing a broader deal.

The Beijing agreement more closely resembles North Korea's June 2004 freeze proposal than it does the U.S. insistence that dismantling nuclear weapons precede any substantial rewards. Clearly, this is a deal the Bush administration would not have made, says Scott Snyder, "if it were not tied down with so many other problems."

North Korea made its own concessions in the Beijing agreement. But "it doesn't necessarily mean Pyongyang is backing down or preparing to abandon its nuclear weapons," argues Kim Sung Han, a senior analyst at the South Korean Foreign Ministry's research institute.

N. Korea's rewards

Administration officials point out that the initial freeze of North Korea's nuclear program, to be implemented in two months, yields only minor compensation, about 50,000 tons of heavy fuel oil. But that is not what Pyongyang sees as its real reward. The lifting of financial measures will facilitate its rapidly growing trade with China and South Korea. Even more important, the South Korean government has already signaled it will now lift the ban on large-scale fertilizer and food shipments -- which are crucial to North Korea's spring planting.

Less visible, but no less vital, the North Koreans are trying to hold off a conservative comeback to power in the South Korean presidential election in December. A North-South summit meeting may take place, which would be part of an effort by the progressive South Korean government to shore up its support.

Ultimately, the Beijing agreement may yield a trade of nuclear facilities for economic and political relations, leaving the nuclear arsenal capped but still intact. For some U.S. experts, that is sufficient.

"It will limit the size of the nuclear arsenal and the amount of bomb fuel," observes former Los Alamos nuclear laboratory director and Stanford scholar Siegfried Hecker. And that, he says, should make it less likely North Korea would sell its nuclear materials or expertise to Iran.

The bargain made in Beijing flows inexorably from North Korea's skillful playing of the escalation game. But it may be the best outcome possible, given that North Korea has already crossed the nuclear threshold and that the Bush administration has squandered U.S. power in the deserts of Iraq.

The harmful environmental effects of livestock production are becoming increasingly serious at all levels-local, regional, national and global-and urgently need to be addressed, according to researchers from Stanford, the United Nations Food and Agriculture Organization (FAO) and other organizations. The researchers, representing five countries, presented their findings on Feb. 19 at the annual meeting of the American Association for the Advancement of Science (AAAS) in San Francisco during a symposium titled "Livestock in a Changing Landscape: Drivers, Consequences and Responses."

Large-scale livestock operations provide most of the meat and meat products consumed around the world-consumption that is growing at a record pace and is projected to double by 2050, said symposium organizer Harold A. Mooney, professor of biological sciences. "We are seeing tremendous environmental problems with these operations, from land degradation and air and water pollution to loss of biodiversity," he said, noting that the developing world is especially vulnerable to the effects of these operations.

Intensive and extensive systems

Symposium co-organizer Henning Steinfeld of the FAO Livestock Environment and Development initiative emphasized that intensive and extensive forms of production are beset with a range of different problems. In "intensive systems," animals are contained and feed is brought to them. "Extensive systems" generally refer to grazing animals that live off the land.

"Extensive livestock production plays a critical role in land degradation, climate change, water and biodiversity loss," Steinfeld said. For example, grazing occupies 26 percent of the Earth's terrestrial surface, and feed-crop production requires about a third of all arable land, he said. Expansion of livestock grazing land is also a leading cause of deforestation, especially in Latin America, he added. In the Amazon basin alone, about 70 percent of previously forested land is used as pasture, while feed crops cover a large part of the remainder.

"We are seeing land once farmed locally being transformed to cropland for industrialized feed production, with grasslands and tropical forests being destroyed in these land use changes, with resources feeding livestock rather than the humans who previously depended on those lands," added Mooney, who co-chaired the scientific advisory panel for the United Nations-initiated Millennium Ecosystem Assessment.

Climate change

According to the FAO, when emissions from land use are factored in, the livestock sector accounts for 9 percent of all carbon dioxide emissions derived from human-related activities, as well as 37 percent of methane emissions-primarily gas from the digestive system of cattle and other domesticated ruminants-and 65 percent of nitrous oxide gases, mostly from manure.

The problems surrounding livestock production cannot be considered in isolation, nor are they limited to the environmental impact, Mooney said, noting that economic, social, health and environmental perspectives "will be critical to solving some of these problems. We hope to develop a greater understanding of these complex issues so that we may encourage policies and practices to reduce the adverse effects of livestock production, while ensuring that humans are fed and natural resources are preserved, today and in the future."

Almost every facet of modern life - from driving to the grocery store to turning on a light - relies on inexpensive and abundant fossil fuels. When burned for power, these fuels yield emissions of carbon dioxide that accumulate in the atmosphere. They are the leading cause of global warming.

Assuring ample energy services for a growing world economy while protecting the climate will not be simple. The most critical task will be curtailing emissions from coal; it is the most abundant fossil fuel and stands above the others in its carbon effluent. Strong lobbies protect coal in every country where it is used in abundance, and they will block any strategy for protecting the climate that threatens the industry. The only practical approach is to pursue technologies that burn coal much more cleanly.

Such new technologies exist on the drawing board, but governments and regulators are failing to bring designs into practice with deliberate speed. Instead, most of the policy effort to tackle global warming has focused on creating global institutions, such as the Kyoto Protocol, to entice change. Although noble, these global efforts usually fall hostage to the interests of critical countries. After negotiating the Kyoto treaty, for example, the United States refused to sign when it found that it could not easily comply with the provisions. Australia did the same, and Canada is also poised to withdraw. Nor have treaties like Kyoto crafted a viable framework for engaging developing countries; these countries' share of world emissions is rising quickly, yet they are wary of policies that might crimp economic growth.

Breaking the deadlocks that have appeared in the Kyoto process requires, first and foremost, a serious plan by the United States to control its emissions. The United States has a strong historical responsibility for the greenhouse-gas pollution that has accumulated in the atmosphere, but little has been done at the federal level. (A few states are implementing some policies, and they, along with rising political pressure, might help to catalyze a more aggressive federal approach.) It will be difficult, however, for the United States (and other industrial countries) to sustain much effort in cutting emissions unless its economic competitors in China and the other developing countries make some effort as well. Without a strong policy framework to contain emissions throughout the world, levels of greenhouse-gas pollution will reflect only the vagaries in world energy markets. We need a proper strategy for moving away from harmful emissions.

A few years ago, many analysts thought that market forces were already shifting away from coal. They predicted the growth of natural gas, a fuel prized for its cleanliness and flexibility. That vision was good news for the climate because electricity made from natural gas leads to half of the carbon-dioxide emissions of electricity from coal. But natural-gas prices, which tend to track oil prices, have skyrocketed over the past few years, and, unsurprisingly, the vision for the growth of natural has dimmed. Natural-gas plants, which accounted for more than 90 percent of new plants built in the 1990s, are harder to justify in the boardroom. Most analysts now see a surge in the use of coal. One hundred new coal-fired plants are in the planning stages in the United States. Absent an unlikely plunge in gas prices, coal is here to stay.

Despite the challenges of handling coal responsibly, the potential of research and deployment of advanced technologies to help the United States and the major developing countries find common interest on the climate problem is great. In advanced industrialized countries, the vast majority of coal is burned for electricity in large plants managed by professionals - exactly the setting where such technology is usually best applied. In the United States, for example, coal accounts for more than four fifths of all greenhouse-gas emissions from the electricity sector.

Most of the innovative effort in coal is focused on making plants more efficient. Raising the temperature and pressure of steam to a "supercritical" point can yield improvements in efficiency that, all told, can reduce emissions about 20 to 25 percent. Boosting temperature and pressure still again, to "ultra-supercritical" levels, can deliver another slug of efficiency and lower emissions still further. Encouraging investments in this technology is not difficult: most countries and firms are already searching for gains in efficiency that can cut the cost of fuel; a sizeable fraction of new Chinese plants are supercritical; India is a few steps behind, in part because coal is generally cheaper in that country, but even there the first supercritical unit is expected soon. Across the advanced industrialized world, supercritical is the norm, at least for new plants. A few companies are taking further steps, investing in ultra-supercritical units. Two such plants are going up outside Shanghai, using mainly German technology, evidence that the concept of "technology transfer" is becoming meaningless in the parts of the world economy that are tightly integrated. Markets are spreading the best technologies worldwide where their application makes economic sense. In other countries, technologies to gasify coal - which also promise high efficiency - are also being tested.

But power-plant efficiency alone won't account for the necessary deep cuts in emissions. Already the growth in demand for electricity is outstripping the improvements in power plants such that the need for more plants and fuel is rising ever higher, as are emissions. This is spectacularly true in fast-growing China.

A radical redesign of coal plants will be needed if governments want to limit emissions of carbon dioxide. Here, the future is wide open. One track envisions gasifying the coal and collecting the concentrated wastes. Another would use more familiar technologies and separate carbon dioxide from other gases. All approaches require injecting the pollution underground where it is safe from the atmosphere. This is already done at scale in oil and gas production, where injection is used to pressurize fields and boost output. The consequences of injecting the massive quantities of pollution from power plants, however, are another matter. Regulatory systems are not in place or tested, and public acceptance is unknown.

While these technologies can work, they won't be used widely before they progress on two fronts. First, they must become commercially viable. Despite the huge potential of adopting them, it is striking how little money is being spent on advanced coal technologies. The U.S. government has created some financial incentives to build advanced coal plants, but much of that investment is slated for plants that are not actually designed to sequester CO2. In fact, the uncertainty of American policy gives investors in power plants an incentive to build conventional high-carbon technology, because it is more familiar to regulators and bankers. Worse yet, increased emissions today might actually improve a negotiating position in the future when targets for controlling emissions are ratcheted down from whatever is business as usual. Some private firms, such as BP and Xcel, are putting their own money into carbon-free power - but the totality of the private effort is small compared with the size of the problem. There are good mechanisms in place for encouraging public research and private investment in such technologies; the real shortcoming is in the paucity of the effort.

The second problem is that countries such as China, India, and other key developing nations won't spend the extra money to install carbon-free coal. Yet these countries' share of global coal consumption has soared almost 35 percent over the past ten years.

The inescapable conclusion is that the advanced industrialized countries must create a much larger program to test and apply advanced coal technologies. Electricity from plants with sequestration might eventually cost half more than from plants without the technology. That's not free, but it is affordable and is less than the changes in electric rates that many Americans already experience and accept.

State and federal regulators need to create direct incentives - such as a pool of subsidies - to pay the extra cost until the technology is proven and competitive with conventional alternatives. That subsidy, along with strict limits on emissions, will set a path for cutting the carbon from U.S. electricity without eliminating a future for coal. They must also extend the same incentives to the major developing countries, which have no interest in paying higher rates for electricity because their priorities do not rest on controlling CO2. Yet these countries' involvement now is essential. Averting emissions has a global benefit regardless of where the emissions are controlled. And developing countries are especially unlikely to shoulder more of the burden themselves, in the more distant future, unless they are first familiar with the technologies.

Solving the climate problem will be one of the hardest problems for societies to address - it entails complicated and uncertain choices with real costs today, and benefits in the distant future. Yet the stakes are high and the consequences of indecision severe. Serious action must contend with existing political constituencies and aim at existing resources that are most abundant. The technologies needed to make coal viable will not appear automatically. An active policy effort - pursued worldwide and initially financed by the industrialized world - is essential.
