Massive eruptions can cool the global average surface temperature by several degrees for several years.

因此大规模的喷发能降低全球表面平均温度数度，时间持续数年。

What that amounts to as a global goal is trying to avoid exceeding global average surface temperature increase of 2c.

这样一种全球目标意味着努力避免2摄氏度以上的全球平均地表温度的增长。

It is not possible to reliably calculate absolute global average surface temperatures, so scientists instead calculate a relative measure called a "temperature anomaly."

要直接得到真实的全球地表气温是不太可能的，所以科学家们要在计算结果中加入“气候异常”的因素。

The average global cloud height is linked to the average global temperature generally, the higher the average cloud height, the higher the average surface temperature, and vice versa.

The global temperature record represents an average over the entire surface of the planet.

This is the global surface temperature departure from the 1961-1990 average, also from the CRU at East Anglia. (Despite all the climategate hubbub, this is still the reference standard in the business).
