Description:: Anthropogenic consumption of fossil fuels releases carbon into the Earth-atmosphere-ocean system at rates unmatched by geologic processes. Yet, some geologic time periods also show evidence of climate forcing related to rapid natural greenhouse gas emissions and can serve as tools to help understand the future trajectory of climate. Geologic events...

Description:: Records of temperature and precipitation during Quaternary interglacial periods on Greenland are notably scarce, limiting assessment of the magnitude and rate of local environmental response to orbitally-driven Arctic warming. It is largely unknown if warming across Greenland was spatially uniform through past interglacials, and if warming was accompanied by major...

Description:: This dissertation explores Holocene climate change along the west coast of Greenland and late Holocene climate variability in the subpolar North Atlantic region using paleolimnology. Lake sediment archives and the climate proxies contained within them provide a valuable window into past temperature change on Greenland, home to one of Earth’s...
