Article: Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space. This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling. This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat. Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling. "We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are _ by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

Article: Sitting across from a German couple and a Chinese mother and child, we were waiting at the Guilin airport for our delayed flight to Shanghai In this last week of our travel-study tour, my husband and I were savoring this mini-break by reading. While surrounded by languages I couldn't understand, it was an American accent that my attention was pulled from my book It also pulled the attention of three rows of people seated around us as the American barked, "Coming through! Coming through!" At the same time, an oversized man pulling an oversized carry-on turned down our row. His wheeled bag caught the foot of the German maa Turning to see what snagged his luggage ,the American bellower yanked his bag hard enough that it crossed over the man's feet It was then that my horror struck. There was no "I'm sorry; no "Excuse me" 5 no "Pardon me" coming from this countryman of mine. While this wasn't the first or last incident where I sighted impolite, ill-mannered, rude Americans in China, each produced similar feelings. First, I was embarrassed that someone from my country was creating a negative impression of Americans. My second reaction was a desire to apologize. I wanted to explain to the ChiiKse woman and her child, the German couple next to her, and everyone nearby that this was not typical American behavior. I wanted them to know "we" were all not like that I never got to explain, or to apologize. Language differences made that option impossible, and rational thinking made it inappropriate. But there turned out not to be a need The German man caught my eye and with a bit of head-shaking, smiling and eye rolling* which I returned, it was clear he knew we were Americans and was expressing that there was "no need" to apologize for "universal idiot behavior".
Answer: uneasy and sorry
answer:
Every time the author saw some Americans' bad behavior in China, she always felt _

Article: Last year more than one million Filipinos worked abroad as servants,nurses,sailors and in other difficult but low-paid jobs.Southeast Asians leave their poorer countries for their richer neighbours. Many of these wage-earners return in the end.In the meantime,they send home huge amounts of money--in the Philippines' case,over 10% of its GDP.Between January and November,the amount was up 18% on the same period of 2005.Poverty and unemployment are still high in the Philippines and other labour-exporting countries.They would be far worse but for this outflow of bodies and inflow of dollars.As for those Asian countries that import labour,as in Europe,falling birth rates mean they are going to need more foreign workers. On January 13th leaders of the Association of Southeast Asian Nations(ASEAN) signed an agreement to help migrant workers--with the realization that the flow of labour between their countries is a growing problem that they cannot blame on outsiders.A 2005 study showed that 8.4 million Southeast Asians worked outside their home countries,but this did not include the huge numbers of Indonesians doing so without papers.So the true total is probably rather higher. Of the ten ASEAN countries,the Philippines,Indonesia,Myanmar,Cambodia,Vietnam and Laos export labour,Singapore and Brunei import it,and Thailand and Malaysia do both.Sziraczki of the UN's International Labour Organization points out that,in the next ten years,the total labour force of the worker-exporting countries should grow by about a third.It makes sense to work on the problem before it gets out of control. People in the receiving countries seem to be worried about competition for their jobs.Most Thais said their government should admit no more foreign workers,and a few thought otherwise.Even in Singapore,just over half of people are against admitting more foreign workers.Malaysians think that the increase in foreign workers has worsened crime rates .
Answer: the country both exports and imports labour force
answer:
It can be inferred from the case of the Philippines that _ .
