Shrinking Glaciers: A Chronology of Climate Change

Analysis of Earth's geologic record reveals how climate has changed over time. In a New Zealand landscape once dominated by glaciers, scientists are using a new technique to determine how long minerals within rocks have been exposed to air since the glaciers melted. The research team is revealing links between glacial retreat and rising levels of carbon dioxide in the air, informing scientists' understanding of global climate change today.
