全球范围内已确认的新生代陨击天文事件有8次，根据陨击直接证据或板块构造演化等推测的陨击事件至少还有3次，这些陨击天文事件都对应了新生代不同程度的气候变化。新生代全球气候变化的触发因素主要包括陨击天文事件、地球轨道参数变化、CO2浓度降低和全球碳循环变化、海洋及大气系统大量甲烷水合物释放、洋流变化及全球规模的构造运动(如构造隆升、超地幔柱、大规模火山活动)等，陨击天文事件是全球气候变化最主要的触发因素。

There were at least eight meteorite-impact astronomical events confirmed during the Cenezoic. However there were still three or more meteorite-impact astronomical events, e. g. , 55 Ma Palaeocene -Eocene thermal maximum, 45 Ma Japanese Sea, and 41 Ma Drake Passage meteortite-impact events inferred from the direct evidences of meteorite impact or plate tectonic evolution during this period. All these meteorite-impact astronomical events may be related to the corresponding global climatic changes during the Cenezoic. The triggering factors for the global climatic changes during the Cenozoic include the meteorite-impact astronomical events, variations in the Earth’ s orbital parameters, decrease of CO2 concentrations and variations in global carbon cycling, release of plentiful methane hydrates in the oceanic and atmospheric systems, variations in oceanic currents and global-scale tectonic movements ( e. g. , tectonic uplift, super mantle plume, and wide-spread volcanic activities) , of which the meteorite-impact astronomical events are interpreted as the key triggering factors for the global climatic changes during the Cenezoic.
