One Nation’s answer: いいえ。温暖化は自然現象だと思うClimate science suffers from problems not found in other areas. Firstly, there are no accurate records for past temperature and it is difficult to reconstruct those temperatures from proxies. Secondly, it is difficult to arrive at a single temperature for the earth in the past and a single temperature for the earth now, so that the two temperatures can be compared and in that way, we can say there is a pattern of warming not seen before the greenhouse gases increased in the atmosphere.Source
