Today’s Wednesday science and climate lesson looks at unusually warm seas, ecological risk, and the vocabulary scientists use to describe stress on marine life.

BBC News reports that the UK Met Office expects a marine heatwave around parts of the UK to reach “extreme” levels, with sea temperatures potentially 4–5C above average in some areas. Scientists are concerned that unusually warm water can damage seagrasses, shellfish, kelp forests and other marine life.
The article explains that recent heat domes and long-term ocean warming have helped fuel the event. Researchers say warmer seas are already changing species patterns, with cool-adapted species such as cod moving north while warm-water species, including octopus, become more common in some UK waters.
BBC News 報導，英國氣象局預測，英國部分海域的海洋熱浪可能達到「極端」等級，某些地區海水溫度可能比平均值高出攝氏 4 到 5 度。科學家擔心，異常偏暖的海水會傷害海草、貝類、海帶森林與其他海洋生物。
文章指出，近期的熱穹現象加上氣候變遷造成的長期海洋暖化，共同推動了這次事件。研究人員表示，海水升溫已經改變物種分布：像鱈魚這類適應冷水的物種往北移動，而章魚等暖水物種則在部分英國海域變得更常見。

海洋的；與海、海洋生物或海水環境有關的。
the natural places where particular plants, animals, or other organisms live and grow.
In article: “Important marine habitats such as seagrasses and kelp forests are suited to cooler waters and can experience high levels of heat stress when temperatures surge.”
棲地、棲息環境；特定植物、動物或生物自然生活與生長的地方。
lasting for a long time, often longer than expected or longer than is healthy.
In article: “The UK has experienced marine heatwaves - prolonged periods of unusually high sea surface temperatures - before.”
持續很久的、延長的；通常指比預期或正常情況更久，且可能造成壓力或問題。
death, especially when discussed as a rate, pattern, or event affecting a group of living things.
In article: “This can reduce their growth or even lead to mass mortality events, which could have knock-on effects for species that rely on these habitats.”
死亡、死亡率；常用於描述某一群生物的死亡情況、比例或事件。
to force something or someone out of its usual place, role, or position; in ecology, to push native species aside by competition or changing conditions.
In article: “You’re also getting other species that could displace native species.”
取代、迫使離開原位；在生態語境中，指外來或新增加的物種因競爭或環境變化而排擠原生物種。
Usage note: This is today’s stretch word. It is common in climate, ecology, conflict, and housing reports when something is pushed out of its normal place.
