As relentlessly bad as the news about global warming ems to be, with ice at the poles melting faster than scientists had predicted and world temperatures rising higher than expected, there was at least a rervoir of hope stored here in Canada's vast forests.
The country's 1.2 million square miles of trees have been called the "lungs of the planet" by ecologists becau they account for more than 7 percent of Earth's total forest lands. They could always be depended upon to suck in vast quantities of carbon dioxide, naturally cleansing the world of much of the harmful heat-trapping gas.
But not anymore. In an alarming yet little-noticed ries of recent studies, scientists have concluded that Canada's precious forests, stresd front damage caud by global warming, inct sand persistent fires, have crosd an ominous (危险的) line and are now pumping out more climate-changing carbon dioxide than they are sinking. Wor yet, the experts predict that Canada's forests will remain net carbon sources, as oppod to carbon storage "sinks", until at least 2022, and possibly much longer.
"We are eing a significant distortion of the natural trend," said Werner Kurtz, nior rearch scientist at the Canadian Forest Service and the leading expert on carbon cycles in the nation's forests. "Since 1999, and especially in the past five years, the forests have shifted from being a carbon sink to a carbon source."
Translation: Earth's lungs have come down with emphyma (肺⽓肿). Canada's forests are no longer our friends.
So rious is the problem that Canada's federal government effectively wrote off the nation’s
forests in 2007 as officials submitted their plans to abide by the international Kyoto Protocol, which obligates participating governments to reduce their greenhou gas emissions.
Under the Kyoto agreement, governments are permitted to count forest lands as credits, when calculating their national carbon emissions. But Canadian officials, aware of the scientific studies showing that their forests actually are emitting excess carbon, quietly omitted the forest lands from their Kyoto compliance calculations.
"The forecast analysis prepared for the government ... indicates there is a probability that forests wo
uld constitute a net source of greenhou gas emissions," a Canadian Environment Ministry spokesman told the Montreal Gazette.
Canadian officials say global warming is causing the crisis in their forests. Inexorably rising temperatures are slowly drying out forest lands, leaving trees more susceptible to frees, which relea huge amounts of carbon into the atmosphere. Higher temperatures also are accelerating the spread of a deadly pest known as the mountain pine beetle, which has destroyed pine forests across British Columbia and is threatening vital wood in the neighboring province of Alberta. More than 50,000 square miles of British Columbia's pine forest have been stricken so far with the markers of death: needles turn bright red before failing off the tree.
Bitter cold Canadian winters ud to kill off much of the pine beetle population each year, naturally
keeping it in check. But the milder winters of recent years have allowed the inct to grow rapidly. "That's what's causing some of our forests to switch from a carbon sink position to a source position," said Jim Snetsinger, British Columbia's chief forester. "Once tho infested trees are killed by the pine beetle, they are no longer taking in carbon--they are giving it off."
Snetsinger noted that eventually, over the cour of a generation, some of the dying forests will begi
n to regenerate and once again begin storing more carbon than they relea. But for the foreeable future, experts say, their models show that Canada's forests will stay stuck in a bad global warming cycle, both succumbing to the effects of climate change and, as they decay and relea more carbon, helping to accelerate it.
That grim reality is stoking a new debate over commercial logging, one of Canada's biggest industries.
Environmentalists contend that the extreme stress on Canada's forests, particularly the old growth northern forest, mean that logging ought to be sharply cut back to prerve the remaining trees—and the carbon stored within them- for as long as possible.
Moreover, they argue that the process of logging releas even more carbon stored in the forest peat(泥炭), threatening to t off what they describe as a virtual "carbon bomb" --the estimated 186billion tons of carbon stored in Canada's forests, which is equivalent to 27 years worth of global carbon emissions from the burning of fossil fuels(矿物燃料).
"There's only one thing which hauls all that carbon out of the forest, .and that's logging," said merran Smith, director of the climate program at the environmental group Forest Ethics. "What weneed to do
is maintain as much biodiversity(⽣物多样性) as we can, so we are prepared to adapt as temperatures change, so we have resilience(恢复⼒)."
But Kurtz and other government scientists contend that logging less is no solution to the global warming problem and would in fact increa carbon emissions over the long term. That's becau, they argue, esntial wood products for construction, furniture and other us would have to be replaced with other man-made materials, such as plastic, steel or concrete, which require the burning of even more fossil fuels -- and therefore carbon emissions -- during their manufacturing process.
"It's not as simple as saying, ' Log less and therefore have more carbon questered in the forests,' ' Kurz said." That is true, but ff in order to do that you have more fossil fuel emitted elwhere, your impact on the climate may be negative." Instead, some scientists argue for more extensive logging of the remaining commercial forests so that older forests, which are most vulnerable to inct infestations and have nearly reached their carbon-storage capacity, can be replanted with younger trees that will take in even more carbon during their growing years.
