Obliquity-paced climate change recorded in Antarctic debris-covered glaciers
The degree to which debris-covered glaciers record past environmental conditions is debated. Here, the authors show that obliquity-paced variations in solar radiation over the past ∼220 ka are expressed in Mullins glacier as repetitive changes in englacial debris and corresponding surface topography...

| Sumario: | The degree to which debris-covered glaciers record past environmental conditions is debated. Here, the authors show that obliquity-paced variations in solar radiation over the past ∼220 ka are expressed in Mullins glacier as repetitive changes in englacial debris and corresponding surface topography. |
