融化的冰原的熔合焓是寒冷冬季天气的一个原因吗?不，有很多原因。-冰原在夏天融化，在冬天重建。这是冬天。-水的聚变焓是333.55焦耳/克。将其乘以每年2800亿吨，就得到9.3×1016焦耳/年。虽然这听起来很多，但与地球每年从太阳接收到的5.5×1024焦耳相比，这只是一个昙花一现。这不是一个寒冷的冬天。虽然美国和加拿大东部的冬天异常寒冷，但北半球的其他地区却相当温暖。例如，格陵兰岛的努克正在遭受热浪袭击。 The current (06:38 UTC 21 January 2018) temperature there is 3°C (37° F), significantly warmer than average. The melting of all that ice might well have an impact on climate, but it's the influx of 280 gigatons (and rising) of fresh water every year into the northern ocean rather than a paltry absorption of 1017 joules of energy every year that will be the cause.
