Abstract
Reconstruction of temperature changes since the Last Glacier Maximum (LGM) have made fundamental contributions to our understanding of past, present and future climate. However, little is known about the sensitivity and mechanism governing tropical climate change, largely due to the insensitivity of tropical continental climate proxies to air temperature. To quantify uncertainties in the temperature record, we use the Hostetler and Bartlein lake model to investigate changes in two large tropical lacustrine systems, Lake Tanganyika and Lake Malawi, by evaluating the energy balance during the LGM, the mid-Holocene, and the pre-industrial period. By comparing the model simulation and the temperature proxies' reconstruction, our work provides new insights into the patterns, amplitude, sensitivity and mechanisms of African temperature change.

    Each year, Brown University showcases the research of undergraduates at our Summer Research Symposium. More than half of the student-researchers are UTRA recipients, while others receive funding from a variety of Brown-administered and national programs and fellowships. Presenters include Brown ...
