La Perouse glacier (IMAGE) American Geophysical Union Caption The trees around La Perouse glacier, in Glacier Bay National Forest, recorded microclimate changes as the glacier advanced and retreated. A new study in AGU’s Geophysical Research Letters reports on how scientists can use those records to predict how near-glacier ecosystems will respond to future climate change.
