與氣候變化相關的心理健康疾病

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.

週一，全球90位科學家對氣候變化影響的警告並沒有帶來好消息。政府間氣候變化專門委員會（IPCC）發佈的報告表示，地球溫度上升半攝氏度之差卻可能意味着拯救地球或帶來災難。

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，氣候變化的影響遠不止破壞地球的生物圈和我們的人身安全。本週發表的另一份報告表明，氣候變化還會對我們的心理健康帶來消極影響。

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.

該研究發表在《美國科學院院報》（PNSA）上，研究將每月氣溫升高與心理健康問題增加相聯繫。實驗證據來源於氣象數據及隨機收集的近200萬美國居民的信息。收集這些數據的時間跨度爲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."

"我們發現，氣溫更高與降水增加都會使心理健康惡化，多年來的氣候變暖與心理健康問題普遍增加有關。將來暴露於熱帶氣旋的頻次和強度有可能增加或帶來更糟的心理健康狀況。"該研究的作者們陳述道。"這些結果爲越來越多的將氣候變化與心理健康聯繫起來的文獻提供了大量補充證據。"

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.

研究員分析了各個城市發佈的氣溫升高與心理健康報告。他們發現：溫度上升1攝氏度與心理健康問題的普遍率增加2%相關。在自然災害方面，該小組還研究了受卡特里娜颶風影響的人的心理健康報告，並指出根據所分析的數據，心理健康問題增長了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.

該報告特別關注由於環境壓力影響（比如溫度、降水、熱帶氣旋）所帶來的心理健康結果，但其它與氣候變化相關的問題也有可能影響人們的心理健康--具體而言，人們知道隨着氣溫升高，自然災害可能會更加頻繁，從而產生的壓力和焦慮心理也會影響心理健康。
