2000至2012年,为何地球并未如科学家预测般温暖?一个由美国科罗拉多州波尔德大学领导的研究小组一直在寻找答案,他们发现其实隐藏的“元凶”显而易见,那就是数十个火山喷发而出的二氧化硫。科学家一直将气候变暖归咎于温室气体。根据之前的观测表明,自2000年以来,平流层气溶胶的增加正好抵消了温室气体排放量的25%。这项新研究表明,中小火山喷发气体减缓了全球变暖。 Why did the Earth not be warmer than scientists predicted from 2000 to 2012? A research team led by the University of Colorado in Colorado has been searching for answers and found that in fact the hidden “culprit” is obvious, that is dozens Sulfur dioxide erupted from volcanoes. Scientists have blamed climate change on greenhouse gases. According to previous observations, the increase in stratospheric aerosols just offset 25% of greenhouse gas emissions since 2000. The new study shows that small and medium volcanic eruption gas slowed global warming.
