I mean, if you actually measure the temperature over a period -- I mean, the temperature has been measured now pretty carefully for about 50, 60 years -- longer than that it's been measured, but in really nice, precise ways, and records have been kept for 50 or 60 years, and in fact, the temperature hadn't really gone up.
我是说，如果你真的测量， 地表温度相当长一段时期 — 我是说，地表温度其实已经被小心观察了 五十到六十年了 — 其实比那个还长， 只是这五六十年来测量工作很细致。 全是记录在案的。 事实上，地表温度没真的上升。
