1·These ratios register the fluctuations of air temperatures over the seasons and years.
这些比率记录了空气温度随季节和年份的波动。
2·During this time when fewer natural foods are available and air temperatures are lower, extra feeding can keep a bird warm and well.
在这段时间里，自然中鸟类的食物越来越少，空气温度也越来越低，额外的喂养可以让鸟类保持温暖和健康。
3·By studying these components, scientists have obtained a detailed archive of many aspects of climate, including air temperatures, snowfall, and concentrations of greenhouses gases in the atmosphere.
通过研究这些成分，科学家们获得了气候的许多方面的详细档案，包括空气温度、降雪和大气中温室气体的浓度。
4·The rise in atmospheric humidity (caused by the higher air temperatures);
大气湿度上升（由气温升高所致）;
5·Air temperatures in the Arctic are rising about twice as fast as in the rest of the world.
北极的气温上升比世界其他地区大约快一倍。
6·The Greenland ice sheet is not merely being melted from above by warmer air temperatures.
格陵兰冰盖不只因气温的升高而从上面融化。
7·Air temperatures over Greenland have increased by about 4 degrees Fahrenheit in the last decade.
过去十年，格陵兰上空空气温度升高了华氏4度。
8·If you think about it, it's almost a miracle that air temperatures are accurately measured at all.
仔细想想，准确测量气温还真算是奇迹。
9·This meansan increase in average air temperatures of around 3C and a reduction insea ice by around a third.
这意味着，那里的平均气温将升高约3摄氏度，海冰将减少约三分之一。
10·In the forest the soil and air temperatures are lower, but the humidity is higher than on the open ground.
林内的土壤温度与空气温度比林外低，而空气湿度则比林外高。
