洋流与全球热量

解释温盐环流（也称全球传送带）如何由温度和盐度差异驱动，使密度更大的海水下沉；说明大西洋经向翻转环流（AMOC）如何将热量从热带输向欧洲；说明海洋吸收了人类活动排放的超过90%的多余热量和约25%的二氧化碳；探讨如果该环流减弱，北欧气候可能会发生什么变化。

Explain thermohaline circulation (the global conveyor belt) as driven by temperature and salinity differences that cause dense water to sink; describe how the Atlantic Meridional Overturning Circulation (AMOC) transfers heat from the tropics toward Europe; explain that oceans absorb more than 90% of excess heat and ~25% of CO2 from human emissions; explore what would happen to Northern European climates if circulation weakened

{{name}}能否解释，为什么与加拿大同纬度的一些地区相比，英国冬季更温和？海洋环流与此有什么关系？如果这种环流减慢，可能会发生什么变化？

Can {{name}} explain why the UK has mild winters compared to parts of Canada at similar latitudes — what does ocean circulation have to do with it, and what might change if that circulation slows down?
