The ocean takes the heat
- The oceans have absorbed most of global warming's extra heat.
- Water can store a huge amount of heat, so it warms slowly.
- But ocean warming 海洋变暖 is now clearly happening.
- It changes life throughout the sea.
海洋承受热量
- 海洋已经吸收了全球变暖大部分额外的热量。
- 水能储存巨量的热量,所以它慢慢变暖。
- 但海洋变暖(ocean warming)现在明显正在发生。
- 它改变整个海洋的生命。
Warmer water, less oxygen
- Like any warm water, a warm ocean holds less oxygen 氧气.
- Fish and other animals struggle to breathe.
- Many species move toward the cooler poles.
- Whole food webs shift as the water heats.
更暖的水,更少的氧气
- 像任何温水,温暖的海洋含有更少的氧气(oxygen)。
- 鱼和其他动物挣扎着呼吸。
- 许多物种移向更凉的极地。
- 随着水变热,整个食物网转变。
The oceans have absorbed most of the extra heat from global warming because water… · 海洋吸收了全球变暖大部分额外的热量,因为水……
Water stores enormous amounts of heat, so the oceans have soaked up most of the warming so far. · 水储存巨量的热量,所以海洋已经吸收了迄今为止大部分的变暖。
Coral bleaching
- Coral 珊瑚 lives with tiny algae 藻类 inside it.
- The algae give the coral colour and most of its food.
- When the water gets too hot, the stressed coral expels the algae.
- The coral turns white — this is coral bleaching 珊瑚白化.
珊瑚白化
- 珊瑚(coral)与内部微小的藻类(algae)共生。
- 藻类给珊瑚颜色和它大部分的食物。
- 当水变得太热时,受胁迫的珊瑚排出藻类。
- 珊瑚变白——这是珊瑚白化(coral bleaching)。
How warming bleaches a coral reef · 变暖如何使珊瑚礁白化
Follow rising ocean heat as it stresses coral and turns a reef white. · 跟随上升的海洋热量,它胁迫珊瑚并使珊瑚礁变白。
Coral bleaching happens when heat-stressed coral… · 珊瑚白化发生在热胁迫的珊瑚……
Stressed coral expels its algae, losing both its colour and its main food source — it bleaches white. · 受胁迫的珊瑚排出它的藻类,失去它的颜色和主要食物来源——它白化成白色。
Like any warm water, a warmer ocean holds less dissolved . · 像任何温水,更暖的海洋含有更少的溶解。
Warmer water holds less oxygen, making life harder for fish and other sea animals. · 更暖的水含有更少的氧气,让鱼和其他海洋动物更难生存。
When reefs die
- A bleached coral is not yet dead, but it is starving.
- If the heat passes, the algae can return and it recovers.
- If the heat lasts, the coral dies.
- Reefs shelter a quarter of all sea life, so their loss is huge.
当珊瑚礁死亡
- 一个白化的珊瑚还没死,但它在挨饿。
- 如果热量过去,藻类能回来,它恢复。
- 如果热量持续,珊瑚死亡。
- 珊瑚礁庇护所有海洋生命的四分之一,所以它们的丧失是巨大的。
As oceans warm, many fish and other species move toward the cooler poles. · 随着海洋变暖,许多鱼和其他物种移向更凉的极地。
Species follow the temperatures they need, so warming pushes many toward the poles. · 物种跟随它们需要的温度,所以变暖把许多物种推向极地。
Select all · 所有 effects of a warming ocean. · 选出海洋变暖的所有影响。
Warming bleaches coral, lowers oxygen, and shifts species poleward. It melts sea ice, not strengthens it. · 变暖使珊瑚白化、降低氧气、把物种推向极地。它融化海冰,而非加强它。
Coral bleaching is a striking example of a symbiosis breaking down. The coral and its algae normally help each other — the algae make food, the coral gives them a home. Heat stress breaks that partnership: the coral ejects the algae, loses its colour and its food supply, and slowly starves. Bleached isn't dead yet, but without cooler water, death follows.
珊瑚白化是共生关系瓦解的一个鲜明例子。珊瑚和它的藻类通常互相帮助——藻类制造食物,珊瑚给它们一个家。热胁迫打破那个伙伴关系:珊瑚排出藻类,失去它的颜色和它的食物供应,慢慢挨饿。白化还没死,但没有更凉的水,死亡随之而来。
A reef through a heatwave:
- A marine heatwave pushes the water a few degrees too warm.
- The stressed coral expels its algae, and the reef turns ghostly white — coral bleaching.
- If the water cools within weeks, the algae return and the coral recovers.
- If the heat drags on, the coral starves and dies, and the fish that depended on the reef vanish with it.
一个珊瑚礁经历一场热浪:
- 一场海洋热浪把水推得高几度、太暖。
- 受胁迫的珊瑚排出它的藻类,珊瑚礁变成幽灵般的白色——珊瑚白化。
- 如果水在几周内冷却,藻类回来,珊瑚恢复。
- 如果热量拖延,珊瑚挨饿而死,依赖珊瑚礁的鱼随它消失。
Ocean warming stores most of global warming's heat. Warmer water holds less oxygen and pushes species toward the poles. Its most visible effect is coral bleaching: heat-stressed coral expels the algae it lives with, turning white and starving. If the heat lasts, the coral dies — and reefs shelter a quarter of all marine life.
海洋变暖储存全球变暖大部分的热量。更暖的水含有更少的氧气并把物种推向极地。它最明显的影响是珊瑚白化:热胁迫的珊瑚排出与它共生的藻类,变白并挨饿。如果热量持续,珊瑚死亡——而珊瑚礁庇护所有海洋生命的四分之一。
