Demise of coral, salamander show impact of Web




DOHA, Qatar – The Internet has emerged as one of the greatest threats to rare species, fueling the illegal wildlife trade and making it easier to buy everything from live baby lions to wine made from tiger bones, conservationists and law enforcement officers said Sunday.

The Web's impact was made clear at the meeting of the 175-nation Convention on International Trade in Endangered Species, or CITES. Delegates voted overwhelmingly Sunday to ban the trade of the Kaiser's spotted newt, which the World Wildlife Fund says has been devastated by the Internet trade.

A proposal from the United States and Sweden to regulate the trade in red and pink coral — which is crafted into expensive jewelry and sold extensively on the Web — was defeated. Delegates voted the idea down mostly over concerns the increased regulations might impact poor fishing communities.

Trade on the Web poses "one of the biggest challenges facing CITES," said Paul Todd, a campaign manager for the International Fund for Animal Welfare.

"The Internet is becoming the dominant factor overall in the global trade in protected species," he said. "There will come a time when country to country trade of large shipments between big buyers and big sellers in different countries is a thing of the past."

The IFAW has done several surveys of illegal trade on the Web and a three-month survey in 2008 found more than 7,000 species worth $3.8 million sold on auction sites, classified ads and chat rooms, mostly in the United States but also Europe, China, Russia and Australia. Most of what is traded is illegal African ivory but the group has also found exotic birds along with rare products such as tiger-bone wine and pelts from protected species like polar bears and leopards.

A separate 2009 survey by the group Campaign Against the Cruelty to Animals targeted the Internet trade in Ecuador, finding offers to sell live capuchin monkeys, lion cubs and ocelots.

"As the Internet knows no borders, it causes several new problems regarding the enforcement of the protection of endangered species," the group said in its report.

John Sellar, CITES' chief law enforcement officer, argued the impact of the Web was overblown and that many species that appear illegal may in fact may be legal. He also said many big traders were reluctant to use the Internet, since payments can be traced and they can be ensnared in undercover operations.

"There seems to be little evidence that there are commercial operations using the Internet," Sellar said. "Although the risks may be small depending on which country you are living in, you can be identified when using the Internet. So there are clearly risks there."

Still, a CITES committee endorsed an e-commerce proposal Sunday that calls on governments to draft measures to address the Internet trade and law enforcement agencies to dedicate a unit to focus on it.

The private sector has also moved to limit the illegal trade.

EBay, which was singled out in the IFAW survey as being a main source of much of the ivory sales, said in a statement that it instituted a complete ban on the ivory trade in 2008, which activists said has helped slow the trade in tusks on the Web.

The newt is a textbook example of what can happen to one species through trade on the Web. According to a study by the WWF, the black and brown salamander with white spots is coveted in the pet trade. They number only around 1,000 and live in Iran's Zagros Mountains. About 200 have been traded annually over the years, mostly through a Web site operated out of Ukraine. Their population has fallen 80 percent.

"The Internet itself isn't the threat, but it's another way to market the product," said Ernie Cooper, who spearhead the investigation into the newt for TRAFFIC Canada. "Most people are not willing to pay $300 for a salamander. But through the power of the Internet, tapping into the global market, you can find buyers."

The red and pink coral, which consist of 32 species, are harvested in deep Mediterranean waters and turned into expensive jewelry either in Italy or cheaper place like Taiwan and China, according to the marine conservation group SeaWeb.

It is the most widely traded and valuable of all precious corals but has no international protection, resulting in a brisk international trade in the species, the group said.

Opposition to the coral proposal was led by Japan, which also successfully spearheaded efforts last week to defeat a proposed ban on the international export of Atlantic bluefin tuna, a key ingredient in sushi. They were joined by several coastal states including Indonesia, Malaysia and Iceland, all of whom argued the corals are crucial to the survival of local communities and are not overharvested.

Meanwhile, delegates approved a voluntary conservation plan for endangered tigers that calls for tougher legislation in countries home to the big cats to tackle widespread smuggling and boost money spent on law enforcement.

The British plan also calls for countries to better control tiger farms and to phase out traditional medicine markets which fuel demand for tiger parts. The proposal includes no funding for the 13 tiger range countries, only a request for donor assistance.

The Tiger population has plummeted because of human encroachment, the loss of nine-tenths of their habitat and poaching to supply the illegal trade. Their numbers have fallen from 100,000 at the beginning of the 20th century to around 3,600 today.

AN AUTO INSIDER TAKES ON CLIMATE CHANGE

TIME MAGAZINE
06-11-07

Thursday, May. 31, 2007 By DAVID VON DREHLE
Congressman John Dingell (D-MI).
ANDREW ECCLES FOR TIME

There are millions of reasons to think Congress won't do much about global warming, all stockpiled in the lobbying budgets of the U.S.'s mightiest interest groups--automakers and other manufacturers, environmentalists, labor unions, farmers, oil companies, coal companies, utilities, the military, antitaxers and so on. A Washington axiom holds that it's always easier to do nothing than to do something. By that standard, tackling climate change, which would affect every industry and every private life, looks almost impossible.

On the other hand, there's John Dingell. Michigan's eternal Congressman, defender of Detroit's carbon-spewing gas hogs, would seem an unlikely cause for optimism. After all, his wife Deborah is a General Motors Foundation trustee, leading his critics to assert that Dingell is literally in bed with the auto industry.

But just as it took anticommunist Richard Nixon to open the door to China, and hip-hop mogul Russell Simmons to denounce misogyny in rap, so Dingell, Democrat from Dearborn and friend of factories, may be the insider able to drive change. At 80, restored to his wide-ranging dominion over the House Committee on Energy and Commerce, "John Dingell is one of the few people with the capacity to manage complex pieces of legislation where there are high stakes," says former House colleague Philip Sharp.

He's smart enough, strong enough, mean enough. Sharp saw Dingell up close the last time Big John reluctantly tackled air pollution--the 1990 amendments to the Clean Air Act that successfully dealt with acid rain. Now Dingell has awakened to global warming, holding more than two dozen hearings on the issue since February and extracting on-the-record promises of cooperation from heads of industry more accustomed to obstruction.

He's not the most famous member of Congress, but he's among the most feared. "A trade-association leader recently told me that his group was going to shift from being against mandatory caps on carbon emissions to being for them," Sharp recounts. "When I asked why, he said, 'There's no way we can go meet with Dingell and just say no.' He didn't mention any other leader of the House or Senate, just Dingell."

He is the last link to a vanished era. Seeing Dingell hobbling along the halls of Congress on his cane or cupping his half-good ear to hear a colleague is like spotting an elderly mammoth alive in the natural-history museum. As long as he's not extinct, he's formidable. Dingell comes from a time when Congress did big things, like Medicare and the Voting Rights Act, as a matter of course. Key Congressmen were known as "bulls," and they didn't look to the White House for permission slips or marching orders. Dingell's first oath of office, in 1956, was administered by Sam Rayburn, whose power is memorialized in the congressional office building bearing his name.

"I am a legislator," said the last woolly mammoth in a recent interview with TIME. By which Dingell means he is in Congress to pass laws, not to wage ideological warfare or get his mug on television. He has never wanted anything beyond life in the House.

The art of moving a major bill is an elusive mix of endurance, persuasion, negotiation, intimidation--and timing. The field is sown with favors large and small over many years and watered with occasional menace. (Ask Dingell how he feels about being called "the meanest s.o.b. in Congress," and he quietly answers, "It's very useful.") With luck, the seeds bear fruit when the votes are finally counted. The process is so slow and cumulative that few people ever become masters. "I've been doing it for years, and I learned from the best," Dingell said, "Rayburn, John McCormack [Rayburn's successor as Speaker], my dad."

John Dingell Sr. (born Dzieglewicz) first won the Dearborn seat in 1932 and held it for more than two decades before his son took over. Together, the Dingell dynasty covers nearly a third of the nation's history. "He was a skinny little shrimp," Dingell said of his dad. "Never drew a decent breath of air. Supposed to have died of tuberculosis in 1914. When the doctor told him that he had six months to live, Pop looked at him and said, 'Doc, I'll piss on your grave.' And Dr. Conway, whom Dad loved, died in '35. Pop died in 1955."

His son practically grew up in the House. Dingell recalls hunting rats "as big as cats" with an air rifle in the Capitol basement, and Franklin D. Roosevelt inscribed a photograph to him--"my friend"--around the time that Dingell was a 12-year-old congressional page. He insists that he never planned to occupy his father's seat, but the senior Dingell's death in office left a humming political machine leaderless and important goals unmet.

Dingell's victory in a special election was the first of 27 consecutive blowouts (some, he insists, harder than others). Unlike his father, Big John was physically imposing, and he filled his office walls with hunting trophies; visitors plead their cases under the cold gaze of Dingell kills. He honored his father by pushing for national health insurance and was chosen in 1965 to wield the gavel when the House passed Medicare.

Then, as now, many members of Congress coveted seats on Ways and Means or Armed Services, but Dingell preferred to master the process outside the spotlight. "No one paid any attention" to his subcommittee on fisheries, "so we were able to get a lot done," he explained. Between 1964 and 1974, Dingell was a driving force behind the National Wilderness Act, the Water Quality Act, the National Environmental Policy Act, the Endangered Species Act, wetlands preservation and bans on ocean dumping and the hunting of sea mammals.

In fact, Dingell would merit a bust on a pedestal at the Sierra Club, except that environmentalists cannot forget that his love for the outdoors is matched only by his love for heavy manufacturing. It was he who amended the Clean Air Act to guarantee that the U.S. auto industry must never be harmed by pollution regulations. And he has stoutly resisted increases in the gas-mileage requirements for sport-utility vehicles and minivans. "I've been looking after American manufacturing and American industry for years--it isn't just autos," Dingell acknowledged proudly. Besides, he added, neither he nor Detroit is to blame for the fact that overall mileage of the U.S. auto fleet hasn't improved. Americans simply prefer high-performance, four-wheel-drive towing machines, even for the preschool car pool. And in this free country, "if the people want something," he said, "they get it." And now the people want to fight global warming. According to Dingell, his shift from skeptic to activist has two explanations. "The scientific evidence is now generally accepted as being clear," he said. "The other thing that has transpired is that there's a public acceptance that something has to be done. And you'll remember that we work for the people."

Those aren't the motives that have Capitol Hill buzzing, however. Insiders wonder if Dingell has been riled up by Speaker of the House Nancy Pelosi, with whom he has a long-running feud. Over the years, Dingell has opposed her rise to party leadership. She, in turn, backed another member of Congress, Lynn Rivers, when Rivers was forced by redistricting to run for Dingell's seat. That was in 2002, but Dingell still savors the drubbing he gave Pelosi's friend. So bad blood was pulsing when the Democrats took the reins of Congress this year and Pelosi appointed a select committee to remove global warming from Dingell's grasp.

No protégé of Rayburn's would ever willingly give up jurisdiction over a lunch menu--let alone the biggest bill in decades. Dingell flexed the muscle of a half-century and rallied his fellow committee chairs against this infringement of prerogatives. The select committee was promptly neutered. "John is the quintessential congressional chairman, protecting his jurisdiction while often reaching to grab someone else's," according to Leon Panetta, who chaired the Budget Committee before serving as White House chief of staff. "The last thing he wants is to lose jurisdiction."

Dingell scoffs at the idea that intramural combat is the root of his new attitude. "I think the select committee is going to be as useless as feathers on a fish, and they're either going to be in my hair or at my feet," he grumbled. But he insisted that he isn't motivated by mere annoyances. In fact, he was moving even before Pelosi acted, he said. Within days of the Democratic victory in November, he had summoned a former member of his committee to return and testify on global warming. "Albert!" he barked sternly when former Vice President Al Gore came on the line. "I'd like you to come in." The Gore hearing was quickly followed by sessions with leading scientists, auto manufacturers, power-company executives, economists and others. Energy and Commerce Committee chief of staff Dennis Fitzgibbons--lured back to Dingell's side after a lucrative stint as an auto-industry lobbyist--describes the "steep learning curve" for members of Congress, who have arrived, one by one, at "their holy [expletive] moment, when they say, 'Wow! This is bigger than I thought.'"

Behind the scenes, Dingell has delivered offer-you-can't-refuse messages to industry. "I've said, 'Fellas, the factual issue appears to be resolving itself. Work with me. I will do everything I can to get you a bill that you probably won't like--but with which you can live. And if you don't, you will have a bill that you won't like and can't live with." When the CEO’s of General Motors, Ford and DaimlerChrysler testified in March, Big John demanded yes or no answers to a series of questions that boiled down to just one: Are you working with us or against us? With varying degrees of pain on their faces, each one promised to cooperate.

But the devil's in the details. And any serious climate-change legislation will be a forest of details. The key feature of any Dingell bill will be a mandatory cap-and-trade system modeled on Dingell's 1990 acid-rain legislation. Industries would be allowed to emit fixed amounts of greenhouse gases according to their share of the overall problem. If a power plant or factory reduces its emissions, the saving can be sold to plants that fail to adhere to the cap. In this way, reductions become valuable and pollution costly. Easy to say but fiendishly difficult to execute in a world where carbon emitters range from coal-fired power plants to the backyard grill. "How many sources of carbon dioxide are we talking about?" mused Fitzgibbons. "How do you allocate the amounts? It's a geometrically complex arrangement."

Europe's carbon cap-and-trade system is off to a poor start because too many permits were issued by governments trying to protect their own industries. On the other hand, too few permits could cripple the American economy. Many economists and environmentalists prefer a straightforward tax on carbon emissions, with proceeds going to fund research and development of alternative energy. It's much simpler--but economists don't run for re-election. House Democrats with long memories recall the whipping they took for backing a similar tax in the Clinton era. The so-called BTU tax was one reason the party lost control of Congress in 1994, and they don't intend to repeat the experience. As Dingell dryly noted in a recent speech, "Many members of Congress remember only too clearly the letters B, T and U."

Even tougher is the one perplexing area in which the fight against global warming conflicts with the U.S.'s goal of greater energy independence: coal. "The U.S. is the Saudi Arabia of coal," Dingell recently declared. We have seemingly endless tons of the stuff, which can be converted into liquid fuel for cars. Coal boosters are pushing legislation through Congress to subsidize the use of coal instead of oil. The only problem: coal is the dirtiest source of greenhouse gases. Representative Rick Boucher, from Virginia's mining country, chairs the subcommittee on energy, but coal's influence goes further than that. Twenty-seven House Democrats hail from coal regions--a deeply meaningful number when Democrats control the chamber by just 16 votes.

The problem is so big, tangled and fraught that some House members prefer to let the Senate take the lead. After all, if Senate Republicans could be lured into a filibuster against a climate-change bill, they might hand the Democrats a strong issue for the upcoming presidential campaign. Dingell, who calls the Senate "a constitutional mistake," wants nothing to do with that strategy. Nor does he have any sympathy for environmentalists who believe the best thing to do is delay action until a Democrat wins the White House.

When both right and left, big business and the ultragreens are worried about what he's up to, call it a Dingell moment. He doesn't like ideologues. Extreme purity annoys him. "I write legislation from the middle," he explained. "I want to build a bill that will have broad bipartisan support that will have the public's confidence." And finally, "a bill that can be signed by the President."

His bipartisanship wears none of the lacy finery of a civics-class lecture. It is a strategy perfected in the bygone era of Democratic dominance of Congress. Dingell knows a purist in his own party can slow him down more than a pragmatist across the aisle. So he likes to get started on a big initiative by cutting a deal with a ranking Republican. Only then does he turn to battle his fellow Democrats. When this works, it can be impressive. The Clean Air Act amendments of 1990 were 13 years in the making (eight of them fairly quiet years as a result of the Reagan Administration's opposition to the bill). When Dingell at last brought the legislation to a vote, however, the amendments passed almost unanimously. But can the strategy work in today's more evenly--and bitterly--divided House?

One advantage Dingell will have in crossing party lines is his record in defending the U.S.'s industrial interests. He stands squarely on the only common ground Congress has found concerning global warming. In 1997 the Senate voted unanimously to condemn Kyoto-treaty provisions that would exempt China and other developing nations from mandatory carbon reductions. Dingell is bulletproof in this area. "I do not propose that my country be the only country that pays the costs of addressing [global warming]," he said. "China is only an example. You've got India, you've got the former Soviet countries, you've got the Europeans. Everybody is trying to give fine speeches, get a lot of credit--and then stick somebody else with the bill."

Where Dingell's influence is most vulnerable, by contrast--his Achilles' heel--is Detroit. He risks losing credibility if he becomes the last man standing between the auto industry and increased-mileage requirements. Momentum is building in the Senate--encouraged by President George W. Bush in his State of the Union speech early this year--for a 4%-per-year increase in corporate average fuel economy (CAFE) standards.

Dingell would prefer to do away with the existing CAFE system for measuring fuel efficiency and replace it with a system that measures tailpipe emissions. After all, a car that runs 25 miles on a gallon of clean biodiesel might be preferable environmentally to a car that runs 35 miles on gasoline or liquid coal.

Maintaining his influence on global warming may mean swallowing the 4% pill--washed down, knowing Dingell, by a fountain of federal subsidies for the retooling of American auto plants. Some friends of the chairman believe that Dingell has chosen the toughest bill of his career to cap his historic tenure. If he survives this Congress and wins one more election, he will pass Mississippi's Jamie Whitten as the nation's longest-serving Congressman.

But Dingell is superstitious about the luck-changing power of grandiose statements, according to a longtime associate. So instead of a grand finale, he quietly but insistently drummed his cane on the floor of his Capitol hideaway office as punctuation for the long list of his legislative achievements. "Look," he closed understatedly, "this is going to be one of the hardest tasks I've ever addressed." That said, "I intend to try and move this. If the problem is as big as everyone says--and it's an enormous problem--then we have a duty to move it. "Don't we?"

US Senators lay out new global warming plan

Thu Aug 2, 4:06 PM ET
WASHINGTON (AFP)

Two veteran US Senators on Thursday rolled out a market-based proposal which they said would reverse the catastrophic worst-case impact of climate change, but still safeguard the US economy.

Senators Joseph Lieberman and John Warner said their plan would focus on 80 percent of greenhouse gas emissions, to cut these by 70 percent below current levels by 2050, and could be used as a blueprint in the fight against global warming.

"We hope it will be a turning point," said Lieberman, who sits as an independent Democrat in the Senate, adding that the plan could reverse US foot dragging on tackling the global threat from climate change.
"We have been slow, we are already late, but not too late," he said.

The proposal, one of several expected to come up in the Senate later this year, lays out a mandatory, market-based cap-and-trade program that would cover 80 percent of US greenhouse gas emissions.
It is designed to cut those emissions back to current levels by 2012, pare them by 10 percent of current levels by 2020, and to reduce them to 70 percent below current levels by 2050.

At the same time, the senators said, their plan, to be the basis of legislation introduced into the Senate later this year, contains "robust" measures to protect American jobs and sustain US economic growth.
It will include the establishment of a Climate Change Credit Corporation to permit industry sectors to buy emissions allowances to regulate the amount of harmful gases they spew into the atmosphere.
Warner, a Republican, said he came late to the issue, after mulling over the potential security implications of global warming.

"In my 28 years in the Senate, I have focused above all on issues of national security, and I see the problem of global climate change as fitting squarely within that focus," he said.
Environmentalists have alleged that since President George W. Bush came to office in 2001 his administration has ignored and even tried to hide looming evidence of global warming and taken little or no action to combat climate change, or the US title as the world's biggest greenhouse gas polluter.

They are also critical of Bush's refusal to ratify the Kyoto protocol on global warming, which he has criticized as excessively flawed and a threat to the US economy.

"Myths and Facts on Global Warming"

Is global warming happening?

MYTH #1:Winters have been getting colder; for example, the winter of 2003–2004 in the northeastern U.S. was the coldest on record. Therefore global warming can’t be happening.

FACT: Winters have been getting warmer. Independent analyses of measurements by different scientists show that the Earth’s climate has warmed overall over the past century, in all seasons, and in most regions. (The studies are summarized in the Third Assessment Report of the Intergovernmental Panel on Climate Change, 2001.)

The skeptics are doubly misleading when they bill the winter of 2003-2004 as record cold in the northeastern U.S. and imply that it disproves global warming predictions. While that winter was colder than average in the Northeast, it ranked as only the 33rd coldest in that region since records began in 1896 (NCDC, Climate of 2004, 2004). January 2004, when the most severe cold of the season occurred, was the 11th coldest January in the Northeast. No all-time low temperature records were broken in the Northeast that winter (NCDC, Climate of 2004, 2004). Only records for a given day of the year, such as January 16th, were broken, which is nothing unusual; the temperatures were not the coldest that had ever been experienced on any day. This contrasts with the 2003 heat waves in Europe, during which many all-time record high temperatures occurred (see Myth #5). In addition, a single spell of cold weather in one small region is no indication that the Earth’s climate is not warming. “Weather” refers to the atmospheric conditions at a particular time and location, while “climate” refers to the long-term average weather for a location. Scientists say that the Earth’s climate has been warming, since, on average, temperatures have been increasing over a long period of time in most regions. The global average temperature for January 2004 ranked as the fourth warmest on record (NCDC, Climate of 2004, 2004), showing that colder-than-usual weather was limited to a small area. Even with global warming, we will occasionally experience an unusually cold winter somewhere on Earth, since weather varies naturally from year to year and from place to place. But record-breaking cold is expected to become less common as the climate continues to warm, shifting the bounds within which weather fluctuates.

MYTH #2: Satellite measurements of temperature over the past two decades show a much smaller warming a few miles above Earth’s surface than is measured by thermometers at the surface. These observations show that computer climate models are wrong, since they predict that increasing amounts of greenhouse gases should cause slightly greater warming above the surface.

FACT: Recent research has corrected problems that led to underestimates of the warming trend in earlier analyses of satellite data. The early work of Spencer and Christy (1990), as well as subsequent revisions (Christy et al. 2003, and references therein), found little or no warming in the troposphere based on satellite data. Skeptics continue to cite these results. But two recent studies made different corrections to those analyses which, when added together, completely eliminate the discrepancy between climate models and observations. Mears et al. (2003), in a reanalysis of the satellite data, took into account various difficulties in determining a temperature trend from weather satellites. First, since no single satellite has been monitoring temperatures for a long period of time, researchers have had to rely on combining data from different satellites. However, different satellites have different instruments that need to be calibrated precisely against one another. Second, even one satellite may not produce consistent measurements over time, since satellite orbits can drift. After accounting for these factors, Mears et al. found a satellite temperature trend closer in size to the surface trend than in previous studies.

Fu et al. (2004) found another major problem with previous analyses. Satellite data that actually blend temperature readings in the stratosphere (the layer of atmosphere above the troposphere) with those in the troposphere were previously misinterpreted as representing only tropospheric temperatures. A strong cooling of the stratosphere over the same time period partly cancels out the tropospheric warming in the satellite measurements (the averaging of a warming trend and a cooling trend results in little trend).3 Fu et al. isolated the portion of the data that represented just the troposphere, and, accounting also for the corrections by Mears et al., found that the troposphere warmed slightly more than the surface, exactly as models predict. This finding dispels the notion that satellite data disprove the role of greenhouse gases in global warming. Weather balloon measurements may also show a smaller tropospheric warming trend than that observed at the surface. But here again, the interpretation of these measurements suffers from difficulties, such as sparse spatial coverage and inconsistencies among instruments (Fu et al. 2004). So trends derived from balloon data are not reliable.

MYTH #3: Even if Earth has been warming over the past century, it is nothing unusual. For example, temperature reconstructions show that there was a period known as the Medieval Warm Period, roughly from A.D. 1000 to 1400, that was warmer than the 20th century. This means that the global warming we are experiencing now is part of a natural cycle.

FACT: Ten independent scientific studies have all found a large 20th-century warming trend compared to other temperature changes over the past millennium or two. (See Figure 1a.) Some of the studies carefully reconstructed a history of temperatures across the globe over the past 1,000 years or more based on different kinds of records (ice cores, tree rings, historical documents, etc.) The rest of the studies calculated past temperature changes using climate models and an estimate of how climatic factors such as sunlight, volcanic eruptions and greenhouse gases changed over time. Uncertainty exists as to exactly how warm the present is compared to the Medieval Warm Period. Recently, von Storch et al. (2004) argued validly that the method used in some temperature reconstruction studies may underestimate the magnitude of past climate changes; however, the study does not answer the question of how warm the Medieval Warm Period actually was. Further support for the idea of an unusual 20th century warming is provided by a recent temperature reconstruction by Moberg et al. (2005), who consciously avoided the method criticized by von Storch et al. Although they find that the Medieval Warm Period may have been warmer than previously estimated, they “find no evidence for any earlier periods in the last two millennia with warmer conditions than the post-1990 period—in agreement with previous similar studies.” In contrast to these two studies, a number of papers arguing for a very warm Medieval Warm Period contain serious flaws. These include articles by Willie Soon and Sallie Baliunas, and Stephen McIntyre and Ross McKitrick. See the box on “The ‘hockey stick’ controversy.” But what if future research were to produce results drastically different from the scientific studies to date, indicating with a high degree of certainty that the Medieval Warm Period was warmer than the present? That would have very little impact on the scientific case for a human cause of the current warming; whether or not the Medieval Warm Period was warmer provides only one piece of evidence in determining what is causing the current warming. That there were warmer periods in the past caused by natural factors (such as millions of years ago when tropical species flourished in polar regions) is insufficient reason to assume that the current warming also is natural. In fact, a whole body of studies separate from the ones discussed above have focused on the physical factors potentially responsible for changing the climate over the past 150 years, and they indicate with a high degree of confidence that most of the warming over the past 50 years was caused by human-produced greenhouse gases. The current warming is unlikely to be entirely natural and inevitable. Humanity largely controls how much climate change will unfold over the coming centuries.

MYTH #4: The Earth’s climate is self-regulating—natural control mechanisms prevent very large swings. For example, Richard Lindzen claims that the Earth has a planetary “iris,” consisting of tropical cloud cover that expands or contracts to control the amount of heat that escapes from the surface out to space (Lindzen et al. 2001).

FACT: The Earth’s climate actually has been very unstable in the distant past. There have been times, hundreds of millions of years ago, when much of the planet was covered in ice.Tens of millions of years ago, tropical species flourished in polar regions (such as during the era of the dinosaurs). A wealth of scientific evidence indicates that the climate has changed significantly and abruptly (within one or a few decades) numerous times in the past. (For a comprehensive review of the literature on this subject, see the 2002 report by the National Academy of Sciences.) While the climate has been relatively stable since human civilization started around 10,000 years ago, the warming projected to occur over the next century with unrestrained emissions of greenhouse gases is likely to exceed anything seen in the last 10,000 years (IPCC 2001). This warming could cross certain thresholds for abrupt climate change, triggering such dangerous events as a shutdown of the ocean currents that supply nutrients to important fisheries and moderate the climate in Europe and other regions (Sarmiento et al. 2004).

MYTH #5: Recent extreme events such as record heat waves, intense precipitation, massive forest fires and worldwide coral bleaching have no link to climate change.

FACT: These recent events are all consistent with a warming world and can be expected to occur more frequently with global warming. Heat waves and extreme precipitation: Weather fluctuates naturally, resulting at times in extreme events, even in the absence of climate change. However, the increase many critiques by global warming skeptics have focused on the work of one particular group of climate scientists, Dr. Michael Mann and colleagues. Their graph of temperature variations over the past 1,000 years (Mann et al. 1999) is featured prominently in the 2001 Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). in global average temperature over the past century, which constitutes a change in climate, shifts the bounds within which weather fluctuates. This climate change increases the likelihood that high temperature records will be broken and intense precipitation events will occur. (Precipitation becomes more intense because higher temperatures promote increased evaporation and thus higher moisture content in the atmosphere.) In fact, some scientists estimate that human-produced greenhouse gases have already at least doubled the chance of an extreme heat wave like the one that scorched Europe in 2003 (Stott et al. 2004). According to measurements, precipitation appears to have increased in intensity over recent decades, at least in certain regions (IPCC 2001).

During the 2003 heat waves in Europe, many all-time high temperature records were broken. The temperature surpassed 100°F in the United Kingdom for the first time since records began (NCDC, Climate of 2003, 2004). Furthermore, the European heat waves were part of an unusually warm summer overall, which appears to have been the hottest in Europe in at least the last 500 years (Luterbacher et al. 2004).

Forest fires: Global warming is expected to cause, and may already have caused, more severe droughts in many regions. The ongoing drought in the western U.S., possibly the worst in 500 years, may be caused by unusually warm waters in the western Pacific and other effects of global warming (Cook et al. 2004; Hoerling and Kumar 2003). Parched conditions and high temperatures associated with drought create ideal conditions for wildfires to spread. Global warming also lengthens the fire season and promotes outbreaks of tree-killing insects, which create a large amount of dry fuel to stoke forest fires (ACIA 2004). The amount of forest burned annually has been increasing over recent decades in some regions, such as the Arctic (ACIA 2004). Alaska experienced its worst fire year ever in 2004, a year with the warmest and third driest summer on record (NIFC 2004).

Coral bleaching: The incidence of large-scale coral “bleaching” events has increased around the world since 1979, and most evidence indicates that these mass bleachings, which can lead to coral death, are caused by global warming (Hoegh-Guldberg 1999). An increase in water temperature causes coral bleaching, and the average surface ocean temperature in many tropical regions rose by almost one degree C (1.8°F) over the last century. In 1997–98, the largest bleaching event on record damaged 16% of the reefs in the world and killed 1,000-year-old corals (Global Coral Reef Monitoring Network 2004; Hoegh-Guldberg 1999).

The Hockey Stick Controversy

The temperature trend is often known as the “hockey stick” because of its shape: nearly flat for most of the millennium and then a sharp upward turn in the 20th century (see Figure 1b). In their critiques of Mann’s findings, the skeptics claim that they have weakened a primary pillar on which the IPCC’s conclusions about human-produced warming rest. That claim is incorrect. The truth is that other independent studies have found similar temperature trends; the differences that do arise do not affect the overall conclusion that 20th century warming is relatively large and longlasting. Furthermore, how warm the Medieval Warm Period was compared to the present, which is the focal point of the skeptics’ critiques, is only a secondary piece of evidence for what is causing the present warming. The IPCC actually assessed an entirely different body of studies to come to the conclusion that humans caused most of the recent climatic change. Some of the analyses critiquing the work of Mann et al. have serious flaws. For example, a pair of similar papers by Willie Soon and Sallie Baliunas use subjective and unscientific methods to paint a picture of a Medieval Warm Period that was much warmer than the present. A rebuttal was published by thirteen climate scientists (Mann et al. 2003a, b). Soon and Baliunas use incorrect criteria for defining past warm periods. They actually consider a period to be warm even if it was simply unusually wet or dry, rather than basing their judgment strictly on direct indicators of temperature. The authors also consider the entire interval, A.D. 800–1300, to be warm, even though their data indicate that the warmth occurred only in scattered regions at any given time. True global warming occurs when temperatures over large areas increase simultaneously. Also, many scientists have found that the results of their studies were misinterpreted by Soon and Baliunas in a way that bolstered the authors’ thesis (Monastersky 2003).

A paper published in 2003 by Stephen McIntyre and Ross McKitrick, claiming to be an audit of a study by Mann et al. (1998), used data from a corrupted electronic file, arbitrarily omitted 80% of the data before 1600, and replaced certain data with incompatible data, artificially resulting in temperatures during the 1400s that were warmer than during the late 1900s (Rutherford et al., in press, 2005). A paper published in 2005 by McIntyre and McKitrick claims that the hockey stick pattern is an artificial result of the method used by Mann et al. rather than an unbiased compilation of the data. Mann et al. used a version of a method known as principal components analysis, which basically boils a large amount of data down to its main features, or “principal components.” One main problem with McIntyre and McKitrick’s critique is that they misunderstand why Mann et al. used principal components analysis — Mann et al. used it to summarize all the important features of the data, not to extract only the one chief feature. The reason McIntyre and McKitrick’s version of the data doesn’t have a hockey stick pattern is that they display only the first principal component, omitting other critical principal components. In addition, scientists have shown that the hockey stick pattern emerges regardless of what version of principal components analysis is used or even whether principal components analysis is used (Rutherford et al., in press, 2005). Recently, von Storch et al. (2004) argued validly that the method used in Mann et al. and some other temperature reconstruction studies may underestimate the magnitude of past climate changes, particularly the longer-lasting, centuryscale changes such as during the Medieval Warm Period. But this paper provides no definitive answer as to how large the underestimates are (Osborn and Briffa 2004). Also, the temperature reconstruction of Moberg et al. (2005), which avoids the method criticized by von Storch et al., still provides no indication that there were any periods in the past 2,000 years that were warmer than the 1990s.

60 Earth Hour 2010


This year, Earth Hour takes place on Saturday, March 27 from 8:30 to 9:30 p.m. (local time). Families are encouraged to join millions of people around the world and turn off their lights for one hour in support of action on climate change. Small acts can make a big difference.

Here are some activities to help you and your family make an evening out of Earth Hour:

1. Make a plan: Engage your family in a conversation about conservation and come up with ideas on how to save energy, limit waste, and make a positive impact on the environment at home. Then discuss other ways your family can take action for the planet year-round, like switching to CFL light bulbs, using cold water to wash your clothes, and buying energy efficient appliances.

2. Community involvement: Find Earth Hour events happening in your community and get involved. Being part of a community with purpose will prompt your kids to start seeking out other opportunities to get involved on their own and inspire more action.

3. Candle-lit games night: Dust off the board games or play a game of flashlight tag. Gather the family for some old-fashioned quality time to remind your children that games can be played without a computer or TV screen and that fun can be had with mom or dad.

4. Take a tour: Explore your neighborhood in a whole new light and take a flashlight walk, or tour around your city using “green” modes of transportation. Walk, bike, skateboard, scooter, or take the bus and show your kids that travel can be fun, and sometimes faster, when you leave the car at home.

5. Scavenge and save: Set up a scavenger hunt in and around your house to mark off areas where energy can be saved. Encourage the kids to place flags or stickers in spots where appliances or computers can be unplugged and lights turned off – highlighting the spots where they can make a difference.

WWF’s Earth Hour Returns for 2010 in Largest Call for Action on Climate Change in History

WASHINGTON, DC, January 19, 2010 – World Wildlife Fund announced today that Earth Hour 2010 will take place on Saturday, March 27 from 8:30 pm to 9:30 pm, with many of the nation’s most iconic landmarks dimming their lights for one hour in what is expected to be the largest call for action on climate change in history.

The initial list of US landmarks taking part in this global climate event includes Mount Rushmore, Empire State Building, the “Welcome to Fabulous Las Vegas,” Harrah’s Caesar Palace and the MGM Mirage on the Las Vegas Strip and San Francisco’s Golden Gate Bridge. New Earth Hour participants in 2010 will include Montezuma Castle National Monument in Arizona and the Soldiers and Sailors Monument in Indianapolis. Other local landmarks taking part include Atlanta’s Bank of America building and the Pike Place Market sign in Seattle, with many more expected to sign on in the days ahead.

WWF officials said they are hopeful of Earth Hour participation in all 50 US states, as Americans from every walk of life, in communities large and small, symbolically dim their lights in solidarity for climate action with hundreds of millions of people around the world. The event will have special significance to Americans in the wake of a US government report from June 2009 which found that every region of the nation is experiencing significant, adverse impacts from climate change including droughts, floods, heat waves and wildfires. A study released in November 2009 by WWF and the insurance company Allianz SE warned that by mid-century, rising global sea levels caused by climate change could increase risks to more than $7 trillion in buildings, transportation infrastructure, and other assets in major U.S. coastal cities, including Boston, Houston, Los Angeles, New York and San Francisco.

“Climate change is real and it’s happening right now in the US, impacting our water resources, energy supplies, transportation, agriculture and health, putting our livelihoods and economic future at risk in every part of the country,” said WWF Climate Director Keya Chatterjee. “Earth Hour is a way for people across the US to join together with people from throughout the world to signal their concern about climate change and send a message about the urgent need for action.”

"Earth Hour directly links with Department of Interior and National Park Service priorities,” said Mount Rushmore National Memorial Superintendent Gerard Baker. “Our stewardship mission is to manage this country's most treasured landscapes unimpaired for the enjoyment of future generations. This mission is being challenged particularly by climate change. As stewards of our national parks, especially considering the challenges of climate change, we must be visible leaders to demonstrate commitment to energy and water conservation... and to use our parks to teach the public about climate change and the ways citizens can reduce their carbon footprints."

A number of organizations have also pledged their support for Earth Hour and will encourage their supporters and the public to take part including Goddard Systems, Inc., HandsOn Network, American Federation of Teachers, NAACP, National Coalition on Black Civic Participation. National Park Service’s WebRangers, American Bird Conservancy, Jane Goodall’s Roots & Shoots, Focus the Nation, National Association of Secondary School Principals, National Association of Student Councils, National Honor Society, National Junior Honor Society, National Science Teachers Association, National Association of Neighborhoods, Apartment and Office Building Association of Metropolitan Washington and Reverb, a non-profit organization that greens concert tours.

“We want children to think about how we all impact the environment in our daily lives and how each one of us can make a difference. Earth Hour provides a great opportunity to accomplish that.” said Joseph Schumacher, CEO of Goddard Systems, Inc., a national childcare franchise and national supporter of Earth Hour 2010. “As educators and as parents, we want to help children understand that how they care for and protect the earth will affect future generations”

“Climate change is the most urgent issue facing our planet today, and we need to unite the world around meaningful action,” Chatterjee said. “With a simple flick of the switch, Americans will not only be sending a signal that they want solutions to the climate crisis, but they’ll be helping to turn the lights out on our nation’s dangerous dependency on foreign oil, and an unsustainable economic future. That’s a powerful message that everyone around the world will be able to see bright and clear on March 27th.”


ABOUT EARTH HOUR:
Since its inception three years ago, Earth Hour has captured the world’s imagination becoming a global phenomenon. Last year, for Earth Hour 2009 nearly one billion people in 4,100 cities in 87 countries on seven continents turned out. In the U.S. alone, 80 million Americans and 318 cities officially voted for action with their light switch. These people and municipalities were joined by iconic landmarks including: the Las Vegas Strip, the Chrysler and Empire State Buildings in New York City, the Space Needle in Seattle, Church of Latter-Day Saints Temple in Salt Lake City, the Gateway Arch in St. Louis and the National Cathedral in Washington DC. International landmarks that turned off their lights included the Great Pyramids of Giza, Parthenon in Athens, St. Peter’s Basilica in Vatican City, Big Ben and Houses of Parliament in London, Paris’ Elysee Palace and Eiffel Tower, Beijing’s Birds Nest and Water Cube, Symphony of Lights in Hong Kong, Sydney’s Opera House and Christ de Redeemer status in Rio de Janeiro.

Collaborating to Conserve the World's Forests

Illegal logging and unsustainable management of forests - driven by the demand for cheap timber and paper products - lead to the loss of nearly 36 million acres of natural forests each year, an area roughly the size of New York state. The world's poorest people often bear the brunt of forest loss, as forest resources sustain most of the world's people living in extreme poverty.

WWF's work with the U.S. government
Our work with the U.S. government includes supporting the reauthorization of the Tropical Forest Conservation Act (HR 2185 in the House of Representatives and S 2020 in the Senate ) that authorizes debt-for-nature swaps and other financial incentives to conserve tropical rainforests, such as the forests of the Amazon. The bill would further expand the program to include coral reefs and associated coastal marine ecosystems, such as those of the Coral Triangle. We are also working to support the Legal Timber Protection Act (HR 1497) which would prohibit imports of illegally harvested plants and timber products into the United States.

Lacey Act
The nation’s oldest wildlife protection statute, the Lacey Act was first enacted in 1900 to combat the impact of hunting to supply commercial markets, interstate shipment of unlawfully killed game, introduction of harmful exotic species, and killing of birds for feather trade. Significantly amended in 1981 and 1988, the Lacey Act has been a tool to combat trafficking in illegal wildlife, fish or plants. Passed on May 22nd 2008, the Act was expanded to protect a broader range of plants, extending the statute’s reach to encompass products, including timber, that derive from illegally harvested plants.

This will help the U.S. to support the efforts of other countries, and its own States, to combat illegal logging making it unlawful to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce any plant, with some limited exceptions, taken or traded in violation of the laws of a U.S. State, or most foreign laws. The Lacey Act also makes it unlawful to make or submit any false record, account or label for, or any false identification of, any plant. It will be unlawful as of December 15, 2008 to import any covered plant or plant product without a declaration.
