A warning on the impact of climate change from 90 scientists around the world issued on Monday did not herald good news. According to the report, issued by the Intergovernmental Panel on Climate Change (IPCC), a half-degree Celsius difference in the Earth's rising temperature could mean the difference between saving the planet and catastrophe.
周一，全球90位科学家对气候变化影响的警告并没有带来好消息。政府间气候变化专门委员会（IPCC）发布的报告表示，地球温度上升半摄氏度之差却可能意味着拯救地球或带来灾难。
The impact of climate change extends beyond ruining Earth's biosphere and our physical safety, however. A separate report published this week suggests that climate change has a negative impact on our mental health, too.
然而，气候变化的影响远不止破坏地球的生物圈和我们的人身安全。本周发表的另一份报告表明，气候变化还会对我们的心理健康带来消极影响。
The study, published in the journal Proceedings of the National Academy of Sciences of the United States (PNAS), links an increase in monthly temperatures to a rise in mental health issues. The empirical evidence stems from meteorological data paired with information collected from nearly 2 million randomly sampled residents in the United States. The data was collected over the span of a decade.
该研究发表在《美国科学院院报》（PNSA）上，研究将每月气温升高与心理健康问题增加相联系。实验证据来源于气象数据及随机收集的近200万美国居民的信息。收集这些数据的时间跨度为10年。
"We find that experience with hotter temperatures and added precipitation each worsen mental health, that multiyear warming associates with an increased prevalence of mental health issues, and that exposure to tropical cyclones, likely to increase in frequency and intensity in the future, is linked to worsened mental health," authors of the study stated. "These results provide added large-scale evidence to the growing literature linking climate change and mental health."
"我们发现，气温更高与降水增加都会使心理健康恶化，多年来的气候变暖与心理健康问题普遍增加有关。将来暴露于热带气旋的频次和强度有可能增加或带来更糟的心理健康状况。"该研究的作者们陈述道。"这些结果为越来越多的将气候变化与心理健康联系起来的文献提供了大量补充证据。"
Researches analyzed warming temperatures and mental health reports in individual cities. They found that a 1 degree Celsius increase was associated with a 2 percentage-point increase in the prevalence of mental health issues. In regards to natural disasters, the team also looked at mental health reports of those affected by Hurricane Katrina, noting that there was a 4 percentage point increase in mental health problems based on the data analyzed.
研究员分析了各个城市发布的气温升高与心理健康报告。他们发现：温度上升1摄氏度与心理健康问题的普遍率增加2%相关。在自然灾害方面，该小组还研究了受卡特里娜飓风影响的人的心理健康报告，并指出根据所分析的数据，心理健康问题增长了4%。
The report specifically focused on mental health outcomes due to the effects of environmental stress - such as temperature, and precipitation, tropical cyclones - but other climate change-related issues are likely to impact mental health as well - specifically, the stress and anxiety of knowing natural disasters could be more frequent as temperatures rise.
该报告特别关注由于环境压力影响（比如温度、降水、热带气旋）所带来的心理健康结果，但其它与气候变化相关的问题也有可能影响人们的心理健康--具体而言，人们知道随着气温升高，自然灾害可能会更加频繁，从而产生的压力和焦虑心理也会影响心理健康。
