wind, and temperature. Climatologists’ research gives insight into regional fish populations during any given season. Climatologists measure global weather events based on trends and patterns observed over time. This allows them to predict future events, such as polar-ice melt, future global temperatures, and the effects of global warming. Climatologists measure the activity of the sun, and its impact on Earth. They research greenhouse gas emission and the greenhouse effect , which occurs when certain gasses are released into the atmosphere. These gasses trap heat by making the atmosphere denser so less heat can escape it. Bioclimatologists research the impact of the climate on living species all around the world. Paleoclimatologists study the history of the earth’s climate. And hydroclimatologists study the impact of the changing climate on global oceans, rainfall, and drought patterns. Climatology is

Trees play a key part in regulating the atmosphere by releasing oxygen and absorbing carbon dioxide (CO 2 ).
