Black carbon,the dark,dusty pollution that comes from burning fossil fuels has settled in locations where tourists and researchers spend a lot of time, scientists found.Even the smallest amount of the dark pollutant can have a significant impact on melting because of its very low reflectiveness:Things that are light in colour,like snow,reflect the sun's energy and stay cool;things that are dark,like black carbon,absorb the sun's energy and warm up. "The snow albedo(反照率)effect is one of the largest uncertainties in regional and global climate modeling right now."Alia Khan,a snow and ice scientist at Western Washington University,told CNN."That's one of the motivations for the study,to quantify the impact of black carbon on regional snowmelt,which is important for quantifying the role of black carbon in the global loss of snow and ice." "Antarctica is sitting there pretty much silently all year.But,if it weren't there, in the state that it is meant to be,the balance that we have in the climate system will no longer be.Marilyn Raphael,a geography professor said."Antarctica's sea ice is also important to maintain a balance in atmospheric circulation,"he added.As waters get warmer,some Antarctic creatures are finding their homes more and more unlivable. "Everything we do has consequences.Raphael said."We need to educate ourselves about those consequences,especially in systems that we know relatively little aboutWe have to be careful that we don't upset the climate balance.” 语篇解读：本文是一篇说明文。文章主要说明了科学家发现燃烧化石燃料后留下的炭黑 会加速南极洲的冰雪融化，并呼吁人们停止破坏气候平衡。 1.Why ca
