The goals of the paleoclimate program are to: (i) provide a baseline for present climate variability and future climate trends, and (ii) improve the understanding of the physical, chemical, and biological processes that influence climate variability and trends over the long-term. Research topics include observational and modeling studies of past climate variability and its drivers and studies that develop new paleoclimate proxies and records. Competitive proposals will address specific aspects of scientific uncertainty for their proposed research. The Paleoclimate program of the Division of the Atmospheric and Geospace Sciences together with other Divisions in the Geoscience Directorate have joined in coordinating and supporting the annual Paleo Perspectives on Present and Projected Climate (P4CLIMATE) competition with the objectives to support studies within two research themes: 1) Past Regional and Seasonal Climate; and 2) Past Climate Forcing, Sensitivity, and Feedbacks. Researchers are encouraged to consider the P4CLIMATE competition as a possible source of support for their global change research. Since proposals eligible for funding in the P4CLIMATE competition are not eligible for funding in the Paleoclimate Program, researchers are strongly advised to contact the Directors of the Paleoclimate Program for guidance as to the suitability of their proposed research for either program. The paleoclimate program strongly encourages proposals from: Researchers at all career stages, including through the AGS Postdoctoral Research Fellowship program. Researchers at all institution types, including MSIs, non-R1 institutions, and institutions in EPSCoR jurisdictions. Researchers from traditionally underrepresented groups in Paleoclimate Science.
