This data set contains methane measurements made in trapped air in the Holocene sections of two ice cores: the Siple Dome ice core in Antarctica the Greenland Ice Sheet Project 2 ( GISP2) ice core in Greenland. Atmospheric Trace Gases » Carbon Dioxide ( CO 2) » Ice Cores. Greenland ice sheet IS melting but much of the heating is coming from INSIDE the earth.The most prominent cycles over geological time are governed by ( among other effects) Milankovitch cycles which are caused by periodic variations in the Earth’ s orbit. Apparently without any of the requisite approvals. We use existing data from four Greenland ice cores,.
