Glacial Ice
qIce cores retrieve climate records extending back thousands of years in
small mountain glaciers to as much as hundreds of thousands of years in
continental sized ice sheets.
qThe antarctic ice sheet has layers
that extend back over 400,000 years.
qThe Greenland ice sheet has layers that extended back 100,000 years.
