Soot. The dirty, dark particles clog lungs, causing asthma and other chronic breathing problems. Turns out cleaning up such soot, along with certain other types of air pollution, could help slow sea level rise too. That's according to new research published in Nature Climate Change.
煤煙，一種又臟又黑的粒子，它會阻塞肺部，引起哮喘及其它慢性呼吸道疾病。事實上，清理這樣的煙塵，以及其它某些污染氣體，能夠幫助減慢海平面上升的速度。這是根據發表在《自然氣候變化》的一項新的研究得來。
Researchers looked at soot and various greenhouse gases that don't last very long in the atmosphere, such as methane, ozone in the lower altitudes and the factory-made refrigerants known as HFCs.
研究人員觀察了煤煙及各種在大氣中不會持續太久的溫室氣體，例如甲烷、低海拔地區的臭氧和工廠生產的制冷劑氫氟碳化物。
Previous studies have shown that cutting these types of air pollution could slow climate change, buying time to bring carbon dioxide emissions under control. The new research shows that such cuts would also significantly slow the rate of sea level rise—by more than 20 percent per year, which could keep the rise under a meter by the end of the century.
以前的研究表明減少這類污染空氣的排放量能夠延緩氣候變化，為控制二氧化碳的排放爭取時間。新的研究證明減少這類氣體的排放量也會極大地延緩海平面上升的速度，每年至少減緩20%，這能使海平面的上升高度在世紀末時保持在一米以內。
Cutting these so-called short lived climate forcers by 30 to 60 percent would prevent roughly a degree Celsius of additional warming, meaning less thermal expansion of ocean waters and less meltdown of ice sheets.
如果將這些所謂的短暫的溫室氣體的排放量減少30%至60%，會防止溫度多升高約一攝氏度，這意味著更少的海水熱膨脹，更少的冰山融化。
Cleansing the air of soot saves lives directly. But it also might help reduce the price demanded by the waves lapping ever higher at the shore.
凈化空氣中的煤煙不僅能直接挽救生命，而且還會減輕海浪拍打在岸上造成的損失。
