無颱風降雨冷卻海水
As an island that relies on the health of its surrounding marine environment, Taiwan is currently facing an existential threat to its coral reefs.
作為一個依賴周邊海洋環境健康的島嶼，台灣目前正面臨著對其珊瑚礁的生存威脅。
rely on…仰賴;依賴=depend onexist(v.)存在existential(adj.)存在的;存在主義的an existential philosopher存在主義的哲學家
The US National Oceanic and Atmospheric Administration (NOAA) has issued coral bleaching alerts for both the northern and southern parts of the island, with southern Taiwan’s waters receiving the highest level – level 2.
美國國家海洋暨大氣總署（NOAA）已針對台灣北部和南部地區發布珊瑚白化警報，台灣南部海域進入最高2級警戒。

Due to increasing sea temperatures caused by climate change, warmer waters have the potential to “cause mass coral bleaching which could result in coral mortality,” according to Taiwan’s Ocean Conservation Administration (OCA).
台灣海洋保育署（OCA）表示，由於氣候變化導致海水溫度升高，溫度升高的海水有可能會「造成大規模珊瑚白化，從而導致珊瑚死亡」。
potential(n.)可能性=possibilitymortality (n.)死亡數字、死亡率infant mortality嬰兒的死亡率
NOAA’s level 2 warning for southern Taiwan indicates a DHW (degree heating weeks) level of 8 degrees Celsius-weeks, causing outcomes consistent with the OCA’s announcement.
NOAA對台灣南部海域的2級警戒指出，熱壓力指數為8攝氏度／週，其結果與OCA的公告一致。
indicate(v.)指出;顯示=showDegree Heating Week (DHW)熱壓力consistent with 與某事物一致、相符
Northern Taiwan has been issued a level 1 alert, which is the second highest, exceeding the two lowest levels of Bleaching Watch and Bleaching Warning.
NOAA另針對台灣北部海域發布1級警戒，為級別第二高的警報，超過了「白化觀察」和「白化警告」的兩個最低級別。
exceed(v.)超過;超出(數量);超越(規定的範圍)
Without typhoon rains to cool ocean waters, these bleaching events could be serious and far-reaching.
若無颱風降雨冷卻海水，這些白化事件可能會相當嚴重且影響深遠。
far-reaching(adj.)影響深遠的;波及廣泛的
As a result, the OCA is working with the National Museum of Marine Biology and Aquarium to survey 30 reef locations around Taiwan, Green Island and Orchid Island.
因此，OCA正與國立海洋生物博物館合作，對台灣、綠島和蘭嶼周圍的30個珊瑚礁棲息地進行調查。
survey(n.)(v.)調查
Of the 20 surveys completed so far this year, sporadic bleaching has been reported in waters shallower than two meters due to the combination of increased temperatures, stronger sunlight and higher amounts of human activity.
在今年迄今為止完成的20項調查中，由於氣溫升高、日照變強和人類活動量增加，在兩米以下的水域觀測到零星的白化。

However, mild bleaching was observed in one area of Taitung County at depths shallower than three meters.
然而，台東縣有塊區域在水深不到三米處觀察到了輕微的白化。
mild(adj.)輕微的
With several other locations exhibiting coral bleaching, the OCA is currently working with the central and local governments, researchers and businesses to create a conservation strategy to address coral bleaching and loss before it’s too late.
隨著其他幾個地點也呈現珊瑚白化的現象，OCA目前正與中央和地方政府、研究人員和企業合作，制定保育策略，希望趁早解決珊瑚白化及損失問題。
