Learning from climate's sedimental journey
By analyzing sediments up to 4,000 years old, an environmental scientist is hoping to provide a tool to help predict future climate change. Ancient records of what was happening with climate conditions can be used with regional climate models to tell a story of what happened in the past and to correlate it to the present and the future. Current models typically use data only for the last 100 years or less and may miss wet and dry periods from past millennia.
