Project outline

The last deglaciation is a period consisting of largescale ice sheet melt, rising┬ásummer solar insolation, increasing greenhouse gas concentrations, and warming surface air temperatures. This relatively smooth transition from the Last Glacial Maximum is also accompanied by well-documented abrupt events such as Heinrich Stadial 1, Meltwater Pulse 1a, the B├Şlling Warming, and the Younger Dryas. However, despite the ability to identify these events in temperature proxy records,┬áprecisely how these events occurred, what triggered them, and if they are linked is still debated.

Regardless of the disagreement on the causal mechanisms of these events, the importance of understanding how these events transpired to predict their potential reoccurrence is widely agreed upon.

My PhD project will provide critical insight into the abrupt climate changes through analysis of complex numerical earth system models, comparisons to observational data, and establishment of links between climate feedbacks and their outcomes. Comparing results of multiple models as well as observational data will assist with not only evaluating model performance but also verifying or refuting previous explanations for the events, laying a foundation for testing and building new hypotheses.

These conclusions will be beneficial not only towards those piecing together the past but also to the understanding of potential catastrophic future events, especially in light of current climate change.
