大西洋环流可能会崩溃

Atlantic Ocean circulatory current could collapse

维持温带气候的洋流系统可能会崩溃。将热量从加勒比海带到北大西洋的大西洋经向翻转环流（AMOC）可能在50年内失效。几十年来，由于全球变暖，它一直在减弱。北大西洋是全球唯一正在变冷的地区。专家们现在认为，AMOC在本世纪跨越临界点的可能性已经从10%增加到50%。

The system of ocean currents that maintains our temperate weather could collapse. The Atlantic Meridional Overturning Circulation (AMOC), which brings heat from the Caribbean to the north Atlantic, could fail within 50 years. It has been weakening for decades due to global warming. The northern Atlantic is the only global region that is cooling. Experts now believe the chance of AMOC crossing the tipping point this century has increased from 10 to 50 per cent.

气象学家表示，AMOC的失败将产生“毁灭性和不可逆转的影响，这将影响整个世界几个世纪”。它会对天气和数亿人的生活造成负面影响。英国的气温可能会降低15摄氏度。寒冷的天气可能“潜在地威胁到欧洲农业的生存能力”。热带季风可能向南转移，造成干旱、饥荒、气候难民和地缘政治紧张局势。

Meteorologists say the failure of AMOC would have "devastating and irreversible impacts, which will affect the entire world for centuries". It would negatively disrupt weather and the lives of hundreds of millions of people. Temperatures in the U.K. could become 15°C lower. Colder weather could "potentially threaten the viability of agriculture" in Europe. Tropical monsoons could shift south, causing drought, famine, climate refugees and geopolitical tensions.

The system of ocean currents responsible for maintaining temperate weather worldwide could collapse. Experts say the Atlantic Meridional Overturning Circulation (AMOC) could fail within 50 years. AMOC brings heat from the Caribbean to the northern Atlantic Ocean. Oceanographers say AMOC has been weakening for decades because of global warming. The northern Atlantic is the only region in the world that is cooling. Experts once believed there was a 10 per cent chance of AMOC crossing the tipping point this century. However, they now say there is a 50/50 possibility.

气象学家表示，AMOC的失败将导致“毁灭性的、不可逆转的影响，这将在未来几个世纪影响整个世界”。它将扰乱全球天气，并对数亿人的生活产生负面影响。科学家预测，英国的气温可能会降低15摄氏度。寒冷的天气可能“潜在地威胁到欧洲农业的生存能力”。此外，热带季风可能向南转移，造成干旱和饥荒。这将造成大量气候难民，加剧地缘政治紧张局势。

Colder weather could "potentially threaten the viability of agriculture" in Europe. Furthermore, tropical monsoons could shift southwards, causing drought and famine. This will create huge numbers of climate refugees and escalate geopolitical tensions.

负责维持全球温带气候的洋流系统正面临崩溃的危险。专家表示，大西洋经向翻转环流（AMOC）可能在未来50年内崩溃。AMOC将加勒比海水域的热量带到格陵兰岛和英国之间的北大西洋。海洋学家表示，由于全球变暖，AMOC在过去几十年里一直在放缓。北大西洋是世界上唯一一个在过去20年里变冷的地区。专家们曾认为，AMOC在本世纪有10%的可能性越过临界点。然而，44位专家公开表示，现在有50%的可能性。

The system of ocean currents that is responsible for maintaining temperate weather worldwide is in danger of collapsing. Experts say the Atlantic Meridional Overturning Circulation (AMOC) could collapse within the next 50 years. AMOC brings heat from Caribbean waters to the northern Atlantic Ocean between Greenland and Britain. Oceanographers say AMOC has been slowing down for the past few decades because of global warming. The northern Atlantic is the only region in the world that has cooled in the past 20 years. Experts once believed there was a 10 per cent chance of AMOC crossing the tipping point this century. However, 44 experts publicly stated that is now a 50/50 possibility.

气象学家认为，AMOC可能在未来几十年内失效。他们表示，这将导致“毁灭性和不可逆转的影响，将在未来几个世纪影响整个世界”。它将扰乱全球天气模式，并对数亿人的生活产生不利影响。科学家们预测，英国的冬季气温可能会降低15摄氏度。更冷的天气可能“潜在地威胁到欧洲西北部农业的生存能力”。AMOC的崩溃可能会使热带季风向南移动，造成大范围的干旱和饥荒。这将导致气候难民数量大幅增加，并加剧地缘政治紧张局势。

Meteorologists believe AMOC could fail in the next few decades. They said this would lead to "devastating and irreversible impacts which will affect the entire world for centuries to come". It would disrupt global weather patterns and adversely affect the lives of hundreds of millions of people. The scientists predict that winter temperatures in the U.K. could become 15°C lower. Colder weather could "potentially threaten the viability of agriculture in northwestern Europe". The collapse of AMOC could shift tropical monsoons southwards, causing widespread drought and famine. This will create huge increases in the numbers of climate refugees and escalate geopolitical tensions.
