在地球构造活动频繁的时期，环非洲、南美洲和欧洲的新海洋盆地开始扩展，产生了新的空间。大气中大量二氧化碳与光合作用的生物发生反应，死的生物随后被埋在海底沉积物中，形成了富含碳元素的页岩。大气中的被固定下来，使得大气中二氧化碳的水平下降，减小了温室效应并降低了全球温度，这对海洋生命来说是非常严重的后果。因此科学家认为，全球变冷或变暖后果同样严重。 下列哪项为真，最能支持科学家的论断?

A.在全球变冷的200年后，由于频繁的火山爆发，使得固化在岩叶中的碳以二氧化碳的形式重回到大气层，部分恢复了温室效应 

B.全球变暖会导致海洋生物生态危机，科学家发现在26万年前全球变冷的时期，海洋生物发生过类似的危机 

C.大规模且长期的自然变化，或由于人类活动而造成全球温室效应在短期内的巨大改变对整个系统来说都具有冲击作用 

D.科学家观察到气侯变冷的发生超过几百万年，而不是几十年或几百年，这还很难和我们迅速变化的现代气侯条件联系起来
