A large hole in the ozone layer was reported to have opened over the Arctic this spring, the first time ozone loss in the northern hemisphere has matched that in the southern.
据报道，今年春天北极上空的臭氧层出现一个大洞，这是首次在北半球出现的臭氧损耗和南半球不相上下。
Nitrous oxide is also a potent greenhouse gas, which contributes to global warming, so efforts to restrict emissions could tackle climate change as well as ozone loss, the scientists say.
科学家们指出，一氧化二氮也是一种威力甚大的温室气体，而温室气体会导致全球变暖。
It is therefore likely that the addition of sulphate to the stratosphere would result in a loss of ozone, and thus in more ultraviolet radiation getting through.
因此，向平流层添加硫酸雾很可能会导致臭氧的损耗，从而使更多的紫外线穿过大气层。
In addition, the larger than expected loss of UV light meant less stratospheric ozone up to 45 kilometers above the surface, but more above that line.
另外，紫外线的丧失量超过预期意味着距地面四千五百米高空的臭氧正在减少，且远远超于这一高度。
These, in turn, have sparked correspondingly sharp rises in greenhouse gas concentrations, ozone depletion, great floods, depletion of fisheries, loss of forests, species loss.
相应地，这一切引起了温室气体浓度急剧上升、臭氧损耗、洪水泛滥、水产枯竭、森林消失、物种消亡。
To build effectual simulation models to evaluate and predict the crop loss by O3 would help to the ozone pollution control and agriculture safety.
建立有效的模型对臭氧造成的作物产量损失进行评估和预测，能为中国臭氧污染的控制和农业安全提供科学依据。
