Climate evolution is a research area that focuses on the changes in Earth's climate over long periods of time. Scientists study past climates through various methods such as analyzing ice cores, tree rings, and sediment deposits to understand how climate has evolved over millions of years. By studying past climates, researchers can gain insights into the factors influencing climate change, such as continental drift, solar radiation, greenhouse gas levels, and volcanic activity. This research area is important for predicting future climate trends and understanding the impacts of human activities on the climate system.
