A climate scientist studies the Earth's climate system, focusing on how it changes over time due to natural processes and human activities. They analyze data related to temperature, precipitation, and atmospheric conditions to understand patterns and trends. Their work helps predict future climate scenarios and assess the impacts of climate change on ecosystems and human societies. These scientists often use computer models to simulate climate behavior and may collaborate with other experts in fields like meteorology, oceanography, and environmental science. Their research is crucial for developing strategies to mitigate the effects of climate change and promote sustainability.
