Volcanic coal-burning Siberia led climate change 252 million years ago
2020/6/19
A team of researchers led by Arizona State University geoscientist Linda Elkins-Tanton has provided the first direct evidence that extensive coal burning in Siberia was a cause of the Permo-...
PETM（古新世-始新世极热事件）发生在距今约5600万年前，是新生代以来最强烈的一次全球快速升温事件。在此期间，大量轻碳（13C同位素含量较少的碳）从岩石圈释放到大气海洋系统中，造成了地球表层碳库中的碳同位素组分发生了显著的负漂。学者们认为PETM时期的碳释放触发了（或者至少加剧了）这次全球升温。PETM持续了大约20万年，其中碳释放持续的时间大约为1000-50000年。在千年到万年的时间尺度...
