Official UN English documents commonly use British English spelling conventions.
中文： 世界氣象組織（World Meteorological Organization，官方名稱在聯合國英式拼寫中常用「Organisation」）是聯合國負責天氣、氣候和水資源國際合作的專門機構。在正式的聯合國國際出版物中，普遍沿用英式英文的拼寫規範。
EN： The past participle phrase 'stored on or beneath the Earth's surface' functions as a post-modifying reduced relative clause (short for 'which was/is stored...'). It directly modifies the noun phrase 'the total volume of freshwater'.
中文： 過去分詞片語「stored on or beneath the Earth's surface」作為後位修飾語，是簡化自形容詞子句（即「which is/was stored...」），用來修飾前面的名詞短語「the total volume of freshwater」（淡水總量）。
Carbon dioxide trapped in polar ice caps provides valuable data on prehistoric climates.
封存在極地冰蓋中的二氧化碳為史前氣候提供了寶貴的數據。
EN： The verb 'plummet' means to fall or drop steeply and rapidly. When expressing a degree of decrease reaching a specific benchmark or threshold, it is followed by the prepositional phrase 'to + [quantity/percentage] + below/above [norm]'.
中文： 動詞「plummet」表示急遽劇跌、直線下降。在描述數值下降至某特定基準點或範圍時，常搭配介系詞結構「to + [數值/百分比] + below/above [基準標準]」。
During the economic recession, consumer confidence plummeted to 15% below historical averages.
在經濟衰退期間，消費者信心指數驟降至歷史平均值的 15% 以下。
EN： In environmental science reporting, statistics like '42% below normal' use 'normal' as a climatological term referring to standard multi-decade baseline averages (typically 30-year reference periods defined by the WMO). The strong verb 'plummet' reflects an increasing journalistic shift toward urgent climate terminology to reflect ecological severity.
中文： 在環境科學報導中，「normal（正常水準）」為氣候學術語，通常指的是世界氣象組織（WMO）所訂定的數十年長期基準平均值（通常為 30 年基準期）。此外，使用「plummet（驟降）」等強烈動詞，反映了當前氣候新聞寫作更傾向於使用具有急迫感的詞彙，以傳達生態危機的嚴峻性。
EN： The verb 'encompass' is a formal, academic alternative to 'include' or 'contain'. It signifies that the subject completely surrounds, spans, or takes in a wide variety of constituent parts as an exhaustive or comprehensive scope.

EN： The phrase 'retained within vegetation' features a reduced relative clause where the past participle 'retained' acts as a post-nominal modifier describing 'water' (equivalent to 'water which is retained within vegetation'). This construction is common in scientific writing for conciseness.
中文： 片語「retained within vegetation」使用了過去分詞後置修飾名詞的結構（相當於省略了「which is」的關係子句：water which is retained within...）。這種精簡的非限定分詞修飾語在科學與學術寫作中非常普遍，有助於行文簡潔精確。
The heat generated during the reaction must be dissipated quickly.
反應過程中產生的熱量必須迅速散逸。
EN： Parallel listing: When listing a series of nouns or noun phrases as compound direct objects, each item typically shares equal grammatical status. In formal writing, the Oxford comma (placed before 'and') ensures clarity, especially when the final item contains its own modifiers.
中文： 平行列舉結構：當列舉一系列名詞或名詞短語作為複合受詞時，各項在語法地位上保持對稱。正式書面語常使用牛津逗號（Oxford comma，即 and 前的逗號），特別是在最後一個列舉項帶有自身修飾語時，有助於避免句意混淆。

我們檢驗了礦物質、有機碎屑、被封存的氣體，以及溶解於海水中的化合物。
EN： In hydrologic science and satellite monitoring (such as NASA's GRACE mission), this combined metric is formally known as 'Terrestrial Water Storage' (TWS). Explaining TWS in accessible news articles requires unpackaging the technical term into its visible and invisible components—from subterranean aquifers to plant moisture.
中文： 在水文學與衛星遙測（例如 NASA 的 GRACE 衛星計畫）中，此綜合指標正式稱為「陸地水儲量」（Terrestrial Water Storage, TWS）。科普與嚴肅新聞報導通常會將這個高度專業的術語拆解，向大眾具體說明它包含地下水層、地表水體以及植被水分等所有組成部分。
EN： The passive construction 'is further compounded by' uses the adverb 'further' (meaning additionally or to a greater degree) before the past participle 'compounded' (meaning made worse or aggravated). This is a formal, high-register structure used to explain escalating problems.
中文： 「is further compounded by」屬於被動語態結構。副詞「further」（進一步、更加）修飾過去分詞「compounded」（使惡化、加重），表達問題或危機受到外力影響而變本加厲，常用於正式報導或學術論述中。
The supply chain disruptions were further compounded by unprecedented labor shortages.
史無前例的缺工問題使供應鏈的中斷情況進一步加劇。
EN： The non-restrictive relative clause introduced by 'which' provides extra, explanatory information about 'so-called weather whiplash events'. Set off by a comma, 'which' functions as the subject of the relative clause and refers back to the plural noun phrase 'events'.
中文： 非限定關係子句以逗號隔開，由關係代名詞「which」引導，在此作為子句的主詞，指涉前方的名詞片語「so-called weather whiplash events」（所謂的氣候鞭笞現象），用以補充說明該現象所帶來的後果與影響。
The country suffered severe heatwaves, which triggered massive power outages across major cities.
該國遭遇嚴重熱浪，導致各大城市接連發生大規模停電。
EN： 'Weather whiplash' is an increasingly prominent scientific and journalistic metaphor borrowed from medical terminology (cervical acceleration-deceleration injury). In climatology, it describes rapid, extreme swings between meteorological opposites—such as severe drought immediately followed by catastrophic downpours—a hallmark of contemporary global warming.
中文： 「Weather whiplash」（氣候鞭笞／天氣甩鞭效應）是借用醫學術語「頸部鞭索症候群（whiplash）」而來的新興氣候術語。它形象化地描寫氣候在兩個極端之間迅速劇烈擺動（例如：極度乾旱驟然轉為災難性暴雨），已成為現代氣候科學與國際主流媒體用來描述全球暖化引發反常現象的標誌性詞彙。
EN： The conjunction 'while' is used here to introduce an adverbial clause of contrast/concession rather than time, highlighting two simultaneous yet differing extreme weather phenomena.
中文： 從屬連詞「while」在此處並非表示時間上的「當……之際」，而是引導對比／讓步副詞子句，相當於「whereas」，用以並列突顯兩種同時發生且具強烈對比的極端氣候現象。
Some industries are flourishing under the new policies, while others are struggling to survive.
某些產業在新政策下蓬勃發展，而其他產業則在生存邊緣苦苦掙扎。
EN： The intransitive verb 'oscillate' followed by the prepositional phrase 'between A and B' denotes swinging or wavering between two extreme states, conditions, or limits.

他的情緒在極度欣喜與深沉絕望之間反覆擺盪。
EN： In climate science and environmental journalism, terms like 'weather whiplash' and descriptions of swings 'between devastating droughts and catastrophic flash flooding' reflect the modern shift from viewing climate change merely as gradual warming to recognizing it as an intensifier of abrupt, erratic hydrological extremes.
中文： 在當代氣候科學與環境新聞報導中，「天候鞭笞效應（weather whiplash）」以及在「乾旱與暴洪之間擺盪」等措辭，反映了環境議題的論述重心已由過去單純的「全球暖化漸進升溫」，轉變為突顯水循環極端不穩定、劇烈在旱澇兩極切換的新常態。
EN： The phrasal verb 'draw upon' (or 'draw on') means to make use of something (such as information, experience, or resources) as a source or basis for further action or research.
中文： 片語動詞「draw upon」（亦作「draw on」）意為「利用、依賴或藉助（資訊、經驗或資源等）」，常在學術與專業寫作中用來指稱研究引用了某些資料或技術作為基礎。
The committee drew upon extensive historical records to draft the new policy.
委員會參考並利用了大量的歷史紀錄來起草這項新政策。
EN： The absolute construction / supplement 'all driven by observed weather data' functions as a reduced non-finite clause (or absolute phrase) providing additional descriptive detail about the preceding noun phrase ('thirteen global hydrological models'). The quantifier pronoun 'all' acts as the subject of the passive participle 'driven'.
中文： 句末的「all driven by observed weather data」為獨立分詞結構（absolute construction）或補充修飾語，量詞代名詞「all」指涉前述的「十三個全球水文模型」，後接過去分詞片語「driven by...」表示被動關係，提供額外的背景技術細節，結構精煉且具高級學術語域特色。
The aircraft underwent testing under multiple extreme conditions, all monitored by sophisticated sensors.
該飛機在多種極端環境下接受測試，所有過程皆由精密感測器進行監控。
EN： The word 'observed' functions here as a participial adjective modifying the compound noun phrase 'weather data', contrasting empirically measured data with modeled or estimated values.
中文： 「observed」在此作為分詞形容詞，修飾名詞片語「weather data」（氣象數據），用以強調該數據來自「實際觀測到的」，而非數值預測或理論估算的數值。
There was a noticeable discrepancy between the projected temperatures and the observed reality.
預測的氣溫與實際觀測到的情況之間存在顯著差異。
EN： In climate and environmental science, distinguishes are strictly made between 'modeled/projected data' and 'observed data' (actual station measurements, satellite records). Emphasizing that hydrological models are 'driven by observed weather data' is a standard academic assurance of empirical rigor and real-world calibration.
中文： 在當代氣候與環境科學領域，學者嚴格區分「模擬／預測數據（modeled/projected data）」與「實測／觀測數據（observed data）」。在報導與論文中特別強調模型是由「觀測到的氣象數據所驅動（driven by observed weather data）」，是為了凸顯該研究並非純粹的理論推演，而是具備實證校準與高度科學公信力的分析。
EN： Reporting verb + noun clause complement: The pattern 'It found that...' uses an impersonal or study-referring pronoun 'It' followed by a declarative content clause acting as the direct object of 'found'. This structure is quintessential in academic and journalistic writing to report findings objectively.
中文： 報導動詞與名詞子句受詞結構：「It found that...」以代名詞 It（指代前文的研究或報告）搭配動詞 found，後接由 that 引導的名詞子句作為受詞，用來客觀陳述研究或調查所獲得的結果，常見於學術及新聞英語。
The report revealed that over half of global wetlands have disappeared since 1900.
該報告顯示，自1900年以來，全球超過一半的濕地已經消失。
EN： Fractional and proportional subject-verb agreement: When fractions or percentages (e.g., 'one third of', 'percent of') modify a noun, the grammatical number of the governing verb corresponds to the head noun following 'of'. Here, 'rivers' is plural, so a plural conceptual agreement applies (though 'exhibited' is past tense and neutral in inflection).
中文： 分數與比例名詞的主謂一致性：當使用分數或百分比片語（如「one third of...」）作主詞時，動詞的單複數取決於 of 後面的核心名詞。在此句中，rivers 為複數名詞，因此在概念上視為複數主詞（雖然過去式 exhibited 無單複數形變化）。
Approximately two thirds of the coral reef are showing signs of severe bleaching.
約有三分之二的珊瑚礁正出現嚴重白化的跡象。
EN： In hydrometeorology, 'normal flow conditions' refers to baseline hydrological discharge calculated over an internationally agreed 30-year climate normal (typically 1991–2020). Describing a drop to 'only one third' signals severe global drought pressure rather than minor seasonal fluctuation.
中文： 在水文氣象學中，「normal flow conditions」（正常流量狀況）是指以國際公認的30年氣候基準期（通常為1991至2020年）為標準計算出的水文基線。當新聞指出僅剩「三分之一」時，代表全球水循環遭遇嚴重乾旱失衡，而非單純的季節性波動。
EN： Compound sentence with parallel quantitative structures: The coordinating conjunction 'and' connects two independent clauses that follow a parallel syntactic pattern: '[Percentage] + [verb] + [noun phrase describing hydrological conditions]'. Notice how '21%' stands alone as an elliptical subject, where 'of global river basin areas' is omitted because it is understood from the preceding clause.
中文： 並列複合句與對稱數量結構：對等連接詞「and」連接兩個獨立子句，形成對稱的句法格局：「[百分比] + [動詞] + [描述水文狀況的名詞短語]」。值得注意的是，後半句的「21%」採用了省略結構（elliptical subject），省略了前句已出現的「of global river basin areas」，避免重複並使文筆更加精練。
Approximately 45% of participants favored the new policy, and 30% expressed strong opposition.
大約 45% 的參與者贊成新政策，而 30% 則表示強烈反對。
EN： Restrictive relative clause modifying 'flows': 'that were below or well below normal' functions as an adjectival clause defining the exact status of the flows. The degree adverb 'well' is paired with the preposition 'below' ('well below') to emphasize a substantial deviation from the baseline standard.
中文： 修飾「flows」的限定關係子句：「that were below or well below normal」作為形容詞子句，精確界定水流量的偏離狀態。副詞「well」在此處與介系詞「below」搭配（well below），意為「遠低於」，用以強調與基準值相比存在顯著差距。
The reservoir's water levels remained well below capacity throughout the summer.
整座水庫的水位在整個夏季都遠低於蓄水容量。
EN： Adverbial modifier in noun phrases ('abnormally elevated discharge rates'): The adverb 'abnormally' modifies the participial adjective 'elevated', which in turn modifies the compound noun 'discharge rates'. This layered modification is typical of academic and formal report registers to maintain objective, measurable descriptions.
中文： 名詞短語中的層級修飾（abnormally elevated discharge rates）：副詞「abnormally」（異常地）修飾分詞形容詞「elevated」（升高的），兩者共同修飾複合名詞「discharge rates」（排泄率/逕流量）。這種多層修飾結構常見於學術研究與正式報告中，旨在維持精準客觀的量化描寫。
Patients showed abnormally elevated enzyme levels during the acute phase.
患者在急性發作期顯示出異常升高的酵素數值。
EN： In hydrology and environmental reporting, 'discharge rates' refers specifically to the volume of water moving through a river channel per unit time (often cubic meters per second), while 'river basin' (or catchment area / watershed) is the fundamental geographical unit used for resource accounting. Reporting dry conditions and extreme flood-potential discharges simultaneously highlights the growing climate crisis phenomenon known as 'weather whiplash' or hydrological polarization.
中文： 在水文學與環境科學報告中，「discharge rates」特指河道在單位時間內通過的水體容積（即流量/逕流量，常見單位為 m³/s），而「river basin」（流域）則是全球水資源統計的基本地理單位。同一份報告同時並列乾旱（低於正常流量）與極端高流量（異常升高排泄量），生動反映了氣候變遷下嚴重的「天氣溜溜球效應」（weather whiplash）或稱水文兩極化現象。
EN： Apposition set off by commas: 'secretary general of the World Meteorological Organisation' is an appositive noun phrase identifying and explaining the proper noun 'Celeste Saulo'. In formal writing, official titles following a name are typically set off by commas and lowercased unless standing directly before the name.
中文： 以逗號隔開的同位語（Apposition）結構：名詞短語「secretary general of the World Meteorological Organisation」作為同位語，用於補充說明專有名詞主詞「塞萊斯特·索洛」的職銜與身分。在正式書面語中，置於人名後方的職銜通常小寫並用前後逗號隔開。
António Guterres, secretary-general of the United Nations, urged global leaders to act immediately.
聯合國秘書長安東尼奧·古特瑞斯敦促全球各國領導人立即採取行動。
EN： Reporting verb with a 'that'-clause complement: The verb 'caution' functions here as a formal reporting verb introducing an indirect statement ('cautioned that...'). It conveys an authoritative warning, which carries more weight and urgency than neutral reporting verbs like 'said' or 'noted'.
中文： 轉述動詞（Reporting Verb）引導 that 名詞子句：動詞「caution」在此作為正式轉述動詞，引導間接引語子句（「cautioned that...」）。相較於中性的「said」或「noted」，「caution」傳達出具有權威性與迫切性的告誡或警告意味。
Economic analysts cautioned that inflation might persist longer than previously projected.
經濟分析師警告稱，通貨膨脹持續的時間可能會比先前預測的更長。
EN： Use of 'effectively' as an adverbial stance marker meaning 'in effect' or 'virtually': It is paired here with the present continuous tense ('is depleting') to highlight an ongoing reality or metaphorical consequence, framing the situation not as an exaggeration, but as what the process practically amounts to.
中文： 副詞「effectively」在此表示「實際上 / 實質上（in effect / virtually）」，作立場修飾語。它與現在進行式（「is depleting」）連用，用來強調一個正在發生且不可否認的現實，指出雖然字面上使用了「儲蓄帳戶」的比喻，但實質後果完全等同於此。
By relying solely on non-renewable energy, the city is effectively borrowing from future generations.
光靠不可再生能源，這座城市實際上是在向未來的世代借貸。
EN： The phrase 'savings account' is used here as an evocative financial metaphor in climate discourse. Scientists frequently compare natural reserves—such as groundwater, glaciers, and deep aquifers—to a 'capital reserve' or 'savings account', contrasting them with rainfall or river flow, which serve as 'regular income'. Drawing down the 'savings account' signifies that humanity is consuming non-renewable reserves faster than natural precipitation can replenish them, risking long-term systemic bankruptcy.
中文： 在此句中，「savings account（儲蓄帳戶）」是當代氣候與環境倡議論述中極具感染力的金融隱喻。科學家與政策專家常將冰川、深層地下水及多年凍土等長期水體比喻為自然界的「本金」或「儲蓄帳戶」，而將每年的降雨和地表徑流視為「日常收入」。動用「儲蓄帳戶」意味著人類的消耗速度已遠遠超出自然循環的補給能力，暗指生態體系正面臨長期的資源「破產」危機。
EN： The sentence uses a reporting structure: a main clause in the simple past ('She emphasized') followed by a nominal 'that'-clause. Within the 'that'-clause, the present perfect tense ('has exhibited') is used to express a state or trend that began in the past (around 2014–2016) and continues to be relevant or ongoing up to the present moment.
中文： 本句採用轉述句構：主句使用一般過去時（'She emphasized'），後接 nominal 'that' 名詞子句。子句內使用現在完成時（'has exhibited'），用以表示該狀態或趨勢始於過去（約 2014 至 2016 年），且一直持續並影響至今。
The report revealed that atmospheric carbon dioxide levels have risen at an alarming rate since the late 19th century.
報告顯示，自 19 世紀末以來，大氣中的二氧化碳濃度已以驚人的速度攀升。
EN： In academic and scientific prose, pre-nominal modifier clustering is common. Here, 'global terrestrial water storage' consists of two adjectives ('global', 'terrestrial') modifying the compound noun 'water storage', and 'a persistent declining trend' combines an adjective ('persistent') and a participial adjective ('declining') to modify 'trend', packing rich scientific data concisely.
中文： 在學術與科學寫作中，名詞前修飾語的堆疊十分常見。本句中 'global terrestrial water storage' 由兩個形容詞修飾複合名詞 'water storage'；而 'a persistent declining trend' 則結合形容詞 'persistent' 與分詞形容詞 'declining' 修飾名詞 'trend'，達到精簡且資訊高度濃縮的表達效果。
Scientists observed a steady upward trajectory in ocean surface temperatures.
科學家觀察到海洋表面溫度呈現穩定的上升軌跡。
EN： The prepositional phrase 'since approximately 2014 to 2016' blends 'since' (marking the starting point of an interval) with the range '2014 to 2016', modified by the hedging adverb 'approximately'. In scientific reporting, such hedging indicates an estimated or multi-year baseline period rather than a single definite point in time.
中文： 介系詞片語 'since approximately 2014 to 2016' 結合了表示起點的 'since'、表時間區間的 '2014 to 2016'，以及緩和語氣的副詞 'approximately'。在科學報導中，這類修飾表示基準期為一估計區間而非單一明確年份，體現嚴謹客觀的學術語氣。
Deforestation rates have stabilized since roughly 2018 to 2020.
自大約 2018 年至 2020 年以來，森林砍伐率已趨於穩定。
EN： In climate science and global policy communications (such as reports by the WMO and IPCC), 'terrestrial water storage' (TWS) is a rigorous hydrological metric combining all water on and beneath land (soil moisture, groundwater, snow, ice, surface water). Using neutral, formal verbs like 'exhibit a trend' rather than sensationalized terms maintains scientific credibility while conveying urgency.
中文： 在氣候科學與全球政策倡議（如世界氣象組織 WMO 或聯合國政府間氣候變化專門委員會 IPCC 的報告）中，「陸地水儲量」（Terrestrial Water Storage, TWS）是一個精確的水文學綜合指標，涵蓋地表與地下所有水體。此處選用高度客觀的中性動詞「exhibit a trend」（呈現……趨勢），能在保持科學嚴謹性與可信度的同時，有效傳達危機的急迫性。
EN： Inverted conditional clause with 'Were': In formal, literary, or high-register English, conditional clauses with 'if' can omit 'if' and invert the subject and auxiliary verb. The structure 'Were + subject + to-infinitive' expresses a hypothetical future condition (equivalent to 'If this trajectory were to continue').
中文： 假設語氣倒裝結構（Were 倒裝）：在正式書面語或高階新聞文體中，若條件子句包含助動詞或 be 動詞，可省略「if」並將主詞與動詞倒裝。「Were + 主詞 + to-不定詞」相當於「If + 主詞 + were to-不定詞」，用來設想未來極不願見到或機率較低的假設情境。
Were negotiations to collapse, both nations would face severe economic fallout.
萬一談判破裂，兩國都將面臨嚴重的經濟衝擊。
EN： Post-positive adjective / Predicative adjunct 'unchecked': Here, 'unchecked' functions as an adjective modifying the state resulting from or accompanying the action 'continue' (meaning 'without being stopped or restrained').
中文： 形容詞用作狀態補語（unchecked）：在此處，「unchecked」作為形容詞修飾動詞「continue」發生時的伴隨狀態，意為「未受遏制地、任其自由發展地」，精煉地表達了被動且放任的情況。
The disease spread unchecked throughout the vulnerable community.
這種疾病在毫無抵抗力的社區中未受控制地蔓延開來。
EN： Linking verb 'prove' + adjective complement: 'Prove' is used as a copular (linking) verb meaning 'to turn out to be' or 'to be found to be over time', followed directly by an adjective (e.g., 'prove irreversible').
中文： 連綴動詞「prove + 形容詞」：動詞「prove」在此作為連綴動詞，意為「證明是……」或「結果顯示為……」，後方直接接形容詞補語（如 irreversible），表示經過時間或事態發展後的最終狀態。
His warnings regarding market instability proved accurate.
他對市場動盪的警告最終被證明是準確的。
EN： In scientific reporting, particularly regarding environmental governance and climate diplomacy, writers frequently employ high-register rhetorical devices like inversion ('Were this... to continue') rather than conversational structures ('If this continues...'). This stylistic choice conveys solemnity, urgency, and institutional authority without sounding overly alarmist.
中文： 在氣候變遷與國際環境治理的專業報導中，作者常偏好使用高階修辭句型（如 'Were this... to continue' 倒裝）而非口語化的 'If this continues...'。這種書面文體能賦予論述莊嚴、緊迫且具權威性的基調，在精準傳達科學警訊的同時避免情緒化煽情。
EN： Personification with non-human subjects: In formal, journalistic, and academic registers, time periods, locations, or inanimate entities frequently serve as the grammatical subject of perception verbs like 'witness', 'see', or 'experience' (e.g., 'The 20th century saw...'). This elevates stylistic formality and places emphasis on the historical epoch rather than human observers.
中文： 非人稱主詞與擬人化動詞搭配：在正式新聞及學術語體中，時間段落、地點或抽象實體常作為感知或經歷類動詞（如 witness、see、experience）的文法主詞（例如「The 20th century saw...」）。這種結構可提高文體典雅度，並將焦點置於該歷史時期本身，而非具體的觀察者。
The last decade has witnessed a dramatic surge in renewable energy adoption worldwide.
過去十年見證了全球採用再生能源的顯著激增。
EN： Quantifier 'the fewest' with countable nouns: 'Fewest' is the superlative form of 'few', used exclusively with plural countable nouns (e.g., 'rivers') to denote the smallest number. It contrasts with 'the least', which modifies uncountable nouns (e.g., 'the least water'). In news journalism, this pattern is often post-modified by prepositional phrases (e.g., 'with normal flows') defining the precise attribute.
中文： 可數名詞的最高級量詞「the fewest」：「fewest」是「few」的最高級形式，專門用來修飾複數可數名詞（如 rivers），表示數量最少；相對地，「the least」則修飾不可數名詞（如 the least water）。在新聞語體中，此結構後方常接介系詞片語（如「with normal flows」）以界定其特質。
This quarter recorded the fewest consumer complaints of the entire fiscal year.
本季度記錄了整個會計年度中最少的消費者投訴案件。
EN： Elliptical time clause with 'since records began': 'Since records began' is a standard journalistic and statistical idiom functioning as a temporal adjunct. 'Records' functions as the subject and 'began' as an intransitive verb, dating back to the inception of systematic data collection.
中文： 時間副詞子句「since records began」：這是一個新聞與統計報告中常見的固定句型，用作時間狀語修飾前述事實。在此子句中，「records」為主詞，「began」為不及物動詞，意指「自開始有系統性記錄以來」。
July was the hottest month globally since records began in the mid-nineteenth century.
七月是自十九世紀中葉有記錄以來全球最熱的月份。
EN： In climate science and meteorological reporting, the phrase 'since records began' typically refers to the start of standardized, instrument-based measurements rather than historical writing. For global river hydrology, satellite monitoring and international observation networks established comprehensive standard models in the early 1990s (hence 1991 as a baseline).
中文： 在氣候科學與氣象新聞中，「since records began」（自開始記錄以來）通常特指現代化、標準化儀器與衛星觀測網絡建立的時間點，而非泛指人類歷史記載。全球水文觀測網與綜合氣候數據庫在 1990 年代初期逐步完備，因此常以 1991 年作為權威對比的統計基準線。
EN： Negative Inversion: When a negative or restrictive expression such as 'Not only' is placed at the beginning of a clause for rhetorical emphasis, subject-auxiliary inversion is required (auxiliary verb + subject + main verb).
中文： 否定倒裝句：當否定或限制性副詞詞組（如「Not only」）置於句首以加強語氣時，子句必須採用主詞與助動詞倒裝的結構（助動詞 + 主詞 + 主要動詞）。
Not only did they arrive late, but they also forgot to bring the tickets.
他們不僅遲到了，而且還忘了帶門票。
EN： Correlative Conjunction 'Not only... but (also)': Used to link two parallel clauses or ideas, emphasizing that both elements are true, with added focus on the second. The adverb 'also' can be placed between the auxiliary and the main verb.
中文： 對等連接詞「Not only... but (also)」：用於連接兩個平行的子句或概念，強調兩者皆屬實，並進一步凸顯後半段內容。副詞「also」通常置於助動詞與主要動詞之間。
Not only has the company reduced emissions, but it has also invested heavily in renewable energy.
這家公司不僅減少了碳排放，而且還大力投資了可再生能源。
EN： Present Perfect Tense with 'in recent years': 'Has accelerated' and 'has intensified' use the present perfect to describe changes or actions that began in the past and continue to have relevance or impact up to the present moment.
中文： 現在完成式搭配「in recent years」：此處「has accelerated」與「has intensified」使用現在完成式，用來描述從過去某時點開始、一直持續到現在或對當前仍具重要影響力的趨勢或變化。
Deforestation has accelerated significantly in recent years due to expanding agriculture.
近年來，由於農業擴張，森林砍伐現象顯著加劇。
EN： In academic and journalistic writing on climate change, correlative structures with negative inversion (such as 'Not only has...') are frequently deployed to convey urgency and highlight multi-faceted crises. Rather than discussing drought or flood in isolation, scientific communicators increasingly emphasize the dual threat of resource loss and climate volatility.
中文： 在氣候變遷相關的學術與新聞報導中，常使用帶有否定倒裝的對等句型（如「Not only has...」）來傳達急迫感並突顯複合式危機。當前科學傳播不再單獨討論乾旱或水災，而是聚焦於「水資源枯竭」與「極端不穩定性」並存的雙重威脅。
EN： The structure 'with + noun/pronoun + participle' functions as an absolute construction providing contextual or causal background information to the main clause. Here, 'With 2025 ranking...' establishes the prevailing climatic condition.
中文： 「with + 名詞/代名詞 + 分詞」構成獨立分詞結構（Absolute Construction），在此句中作為修飾整個主要子句的狀語，表達背景情境或原因。此處「With 2025 ranking...」點明了全球氣溫屢創新高這一關鍵背景。
With temperatures continuing to rise, glaciers are retreating at an unprecedented pace.
隨著氣溫持續攀升，冰川正以史無前例的速度消退。
EN： In the phrase 'indispensable to mitigating', 'to' is a preposition (not part of an infinitive marker), and therefore must be followed by a gerund (-ing form) or a noun phrase.
中文： 在短語「be indispensable to doing sth」中，'to' 是介系詞而非不定詞標記，因此後方必須接動名詞（-ing 形式）或名詞片語，表示「對於做某事是不可或缺的」。常見混淆點在於常被誤寫為不定詞原形動詞。
International collaboration is vital to preserving global biodiversity.
國際合作對於保護全球生物多樣性至關重要。
EN： The past participle 'documented' is used as a post-positive modifier following the superlative phrase 'the warmest years ever', meaning 'that have ever been documented'.
中文： 過去分詞「documented」置於最高級片語「the warmest years ever」之後作後置修飾語，相當於關係子句「that have ever been documented」，簡潔地表達「有記錄以來」。
This was one of the strongest storms ever recorded in the region.
這是該地區有記錄以來最強烈的風暴之一。
EN： In climate science communications, phrases like 'ever documented' or 'on record' denote official observational datasets maintained by agencies like the WMO and NASA (dating back to the late 19th century). Furthermore, the pairing of 'urgent' and 'coordinated international action' reflects typical diplomatic and scientific discourse advocating for multilateral treaties.
中文： 在當前氣候變遷與環境科學的國際公報中，「ever documented」（有記錄以來）特指世界氣象組織（WMO）、美國太空總署（NASA）等權威機構自 19 世紀晚期建立以來的儀器觀測紀錄。此外，「urgent, coordinated international action」（緊迫且協調一致的國際行動）是聯合國與國際科研組織倡導跨國減碳及水資源治理時極具代表性的外交與政策用語。
