For example , emitting aerosols at rates of 30 micrograms per meter-squared yielded temperature decreases of roughly 7 degrees celsius during the hottest part of the day .
例如，当气溶胶的排放速率为三十微克每平方米时，在一天中最热的时候气温下降了大约7摄氏度。
But while the long article included a quotation from mr. locke in which he acknowledged that the united states had been emitting greenhouse gases for 150 years , neither xinhua article included any mention of china 's role or of the american criticisms of that role .
