Late Quaternary research focuses on the period of Earth's history that includes the last 2.6 million years. This research area primarily examines the environmental changes, climate fluctuations, and geological events that have occurred during the late Quaternary period. It often involves studying different proxies such as sediments, ice cores, and fossil records to reconstruct past climate conditions and understand the impact of human activities on the environment. Late Quaternary research is crucial for gaining insights into the Earth's past dynamics and can help predict future climate trends.
