In the past few decades, average Arctic temperatures have warmed roughly 3.6 degrees Fahrenheit (2 degrees Celsius); average temperatures in Antarctica have warmed slightly less than 1.8 degrees Fahrenheit (1 degree Celsius).

在过去的几十年里，北极地区的平均气温上升了大约3.6华氏度（2摄氏度）；南极洲的平均气温上升了不到1.8华氏度（1摄氏度）。

The calculation of degree-day is usually based on the definiation of basic temperature and average temperature in the day. The basic temperature is often calculated according to energy supply, physiological demand of human body, the level of economic development and the character of temperature changes. There are mainly four methods for the calculation of average day temperature. The most popular way is to get the average of the highest temperature and the lowest one.

度日计算的前提是基础温度和日平均温度的确定，其中基础温度往往是根据能源供应、人体生理需求、经济水平以及温度变化特点而人为规定的，也有一些学者尝试用数学方法求得；日平均温度的计算方法主要有4种，国外学者经常采用的是取日最高气温和最低气温算术平均值的方法。
