Humans have only migrated into temperate and subarctic latitudes in the last hundred thousand years or so.

人类在过去大约 10 万年里，才迁移到温带和靠近北极地区。

At high latitudes in both hemispheres, temperatures dropped by about 15 degrees Celsius.

在两个半球的高纬度地区，气温 下降了约 15 摄氏度。

At higher latitudes in the summer, the Sun is higher in the sky and sunlight penetrates deeper into the ocean.

在夏季的高纬度地区， 太阳在天空中的位置更高，阳光穿透到海洋的深处。

You need to have oversight over your people, even if you're allowing them a lot of latitude in what they do.

你需要对你的员工进行监督，即使你允许他们在工作中有很大的自由度。

Over the course of generations, humans living at the Sun-saturated latitudes in Africa adapted to have a higher melanin production threshold and more eumelanin, giving skin a darker tone.

数代之后生活在阳光充沛的赤道地区周围的非洲居民进化出了更高的黑色素产生阈值，同时分泌出更多的真黑素加深了皮肤的色调。

But the changing conditions change the latitudes in the areas where these microbial diseases can become endemic and change the range of the vectors, like mosquitoes and ticks that carry them.

但是现在这些正在发生的变化，改变了微生物疾病变成地方性疾病的区域，也使得携带细菌的生物，像蚊子和蜱的活动范围发生了变化。

Closer to home, our moon is 3.8 centimeters farther away from our revolving Earth, which has spun me around 12.7 million kilometers from here at my latitude in Austin, TX.

在离家更近的地方， 我们的月球距离我们旋转的地球更远 3.8 厘米，这使我在德克萨斯州奥斯汀的纬度上从这里旋转了大约 1270 万公里。
