Climate change
氣候變化
The temperature rises
溫度上升
A new report produces a mixture of alarm and apathy
新報(bào)告敲響警鐘，對(duì)此有人驚慌，有人冷漠
For decades scientists have warned that rising atmospheric concentrations of greenhouse gases from the burning of fossil fuels
幾十年來(lái)，燃燒化石燃料導(dǎo)致溫室氣體濃度不斷上升，
risk adversely affecting the climate, increasing ocean acidity, the frequency of freak weather and other symptoms of planetary ill-health.
科學(xué)家一直都在警告這將惡化氣候、增加海洋酸度、增高天氣反常頻率，并會(huì)導(dǎo)致其他地球不健康的癥狀表現(xiàn)。
But it seemed that keeping the temperature within 2°C of pre-industrial levels, although disruptive, would probably leave Earth in a chronic but stable condition.
但是如果溫度浮動(dòng)相比工業(yè)化前不超過(guò)2°C，盡管有一定破壞性，但是可能會(huì)使地球處于一種慢性惡化但是穩(wěn)定的狀態(tài)。
A report unveiled this week from the Intergovernmental Panel on Climate Change (IPCC), a UN-backed body that musters the science needed to inform policy, shows how optimistic that was.
聯(lián)合國(guó)政府間氣候變化專門委員會(huì)（IPCC）是由聯(lián)合國(guó)支持的組織，主要任務(wù)是為政策制定提供科學(xué)信息。本周，委員會(huì)公布了一份報(bào)告，報(bào)告表明這樣的想法過(guò)于樂(lè)觀。
The survey was commissioned in 2015 by the then 195 signatories of the Paris climate agreement—
這項(xiàng)調(diào)查是2015年由當(dāng)時(shí)195個(gè)巴黎氣候協(xié)議簽署國(guó)委托進(jìn)行的——
which commits them to keep warming "well below" 2°C and to "pursue efforts towards 1.5°C".
規(guī)定協(xié)定國(guó)要將氣候升溫“最好”控制在2°C以下，且“力求1.5°C”。
The effects and technical feasibility of keeping warming within this tighter limit were the report's focus.
報(bào)告重點(diǎn)是在這個(gè)更嚴(yán)格的限度內(nèi)保持氣候變暖的影響和技術(shù)可行性。
How it was put together, the message it contains and the reaction it elicited all matter.
報(bào)告的組合方式、內(nèi)容信息以及影響都很重要。
First, the way it was assembled.
首先是組合方式。
Although the report presents no new science of its own, its survey of more than 6,000 studies is meticulous.
盡管這份報(bào)告本身并沒(méi)有什么新科學(xué)，但它對(duì)6000多項(xiàng)研究的調(diào)查卻十分細(xì)致。
With every passing year scientists amass more data about how the climate has already changed.
隨著時(shí)間的流逝，科學(xué)家們積累了更多關(guān)于氣候變化的數(shù)據(jù)。
And, as many people battered in Florida this week by Hurricane Michael will attest, it is changing faster than anyone foresaw even two decades ago.
而且，本周在佛羅里達(dá)遭受颶風(fēng)“邁克爾”襲擊的人將會(huì)親身體驗(yàn)，氣候變化速度甚至比20年前任何人預(yù)想的都要快。
This new knowledge, together with improved understanding of the complex climate system, makes projections like those the IPCC has compiled more compelling.
這種新認(rèn)知，加上對(duì)復(fù)雜氣候系統(tǒng)的更好理解，使得政府間氣候變化專門委員會(huì)的預(yù)測(cè)很有說(shuō)服力。
Uncertainties remain;
但不確定性仍然存在；
individual research contained within the report may yet be challenged.
報(bào)告中包含的個(gè)人研究可能會(huì)受到挑戰(zhàn)。
But in study after study, page after page, fact after fact, the evidence for anthropogenic climate change, long clear, is harder than ever to ignore.
但在大量研究中得出的人類活動(dòng)導(dǎo)致氣候變化的證據(jù)，顯而易見(jiàn)再難忽視。
