Climatologists must interact with other scientists from other disciplines to better understand historical climate changes. The scientific fields which can answer the questions related to past climates include geologists, anthropologists, paleohydrologists and historians. Finally, it is important that climatologists apply their results to other related fields. This would assist experts in these fields to adjust their activities to climatic information. The field of climatology has grown as we have been better able to observe the various weather elements.
New observations provide basic information about how the atmosphere works.
Describing the climate rather than explaining it. Early on, climate was associated with seasonal events such as the flooding of the Nile each year in Egypt. 1900s - It was possible to describe the climate of much of Earth's land surface and some oceans. This climate knowledge was based on local observations of temperature and precipitation. These observations were and still are the main elements because of their usefulness, especially to agriculture.
