The world is entering uncharted territory with climate change. Scientists and policymakers are scrambling to pinpoint what\u2019s happening, where we\u2019re headed and how to respond.<\/p>\n\n\n\n
Nebraska paleontologist Ross Secord is among them. With a nearly $350,000 grant from the National Science Foundation, he\u2019s pursuing a first-of-its-kind study that explores how climate change affected the environment, ecosystems and organisms during the Early Eocene Climatic Optimum. The EECO took place about 52 million years ago and was the warmest interval of the past 70 million years.<\/p>\n\n\n\n
Marked by a shift to high carbon dioxide levels, warm temperatures and increased precipitation, the transition from pre-EECO to the EECO is considered a good analogue for future climate change. Better understanding ecological changes during this time may provide clues to scientists trying to forecast future conditions.<\/p>\n\n\n\n
\u201cStudying intervals in the geologic record where the global warming experiment has already occurred gives you a way of figuring out what the possible outcomes of climate change may be,\u201d said Secord, associate professor of earth and atmospheric sciences.<\/p>\n\n\n\n
Secord and collaborators are analyzing fossil records from Wyoming\u2019s Bighorn and Wind River basins, which have rich collections from the EECO. They will identify the types of forest structure that prevailed during that period. Their findings will clarify the interrelationship between climate change, forest structure and mammal evolution.<\/p>\n\n\n\n
Secord will analyze fossil teeth of EECO mammals to infer the types of habitats present in the environment. Mammalian tooth enamel preserves the different types of carbon found in the plants they consumed. This process is part of stable isotope geochemistry, one of Secord\u2019s specialties.<\/p>\n\n\n\n
Nebraska\u2019s Judy Diamond is leading an outreach plan that provides 50 rural and tribal libraries in Nebraska and across the nation with current information about climate change, water resources, mammal evolution and more.<\/p>\n\n\n\n
Diamond and advisers developed a list of publications spanning all ages from which partnering libraries can select materials. Showcasing the work of Indigenous authors is a priority.<\/p>\n\n\n\n
\u201cThis grant provides an opportunity for these libraries to acquire the very best and latest books on these subjects,\u201d said Diamond, University Libraries and Museum professor.<\/p>\n","protected":false},"excerpt":{"rendered":"
