The U.S. National Science Foundation (NSF) is offering a federal grant opportunity titled "Paleo Perspectives on Present and Projected Climate" (P4CLIMATE) aimed at fostering interdisciplinary research in paleoclimate science. This initiative seeks proposals that utilize observational and modeling studies to address two key research themes: Past Regional and Seasonal Climate, and Past Climate Forcing, Sensitivity, and Feedbacks, with a focus on utilizing geological records and environmental archives to enhance understanding of climate behavior over multi-decadal to millennial time scales. The total estimated funding for this program is $14 million, with a minimum award floor of $400,000, and proposals can be submitted without fieldwork in the Antarctic or with fieldwork in the Arctic. Interested applicants can find more information and support by contacting NSF grants.gov support at grantsgovsupport@nsf.gov, and the opportunity is set to close on June 7, 2025.
