Holocene hydrologic variation at Lake Titicaca, Bolivia/Peru, and its relationship to North Atlantic climate variation
Abstract A growing number of sites in the Northern Hemisphere show centennial‐ to millennial‐scale climate variation that has been correlated with change in solar variability or with change in North Atlantic circulation. However, it is unclear how (or whether) these oscillations in the climate syste...

Abstract A growing number of sites in the Northern Hemisphere show centennial‐ to millennial‐scale climate variation that has been correlated with change in solar variability or with change in North Atlantic circulation.
