Climate scientists are experts in the field of study that focuses on understanding and predicting changes in Earth's climate. They use a combination of observations, theoretical models, and computer simulations to analyze data related to weather patterns, temperature fluctuations, precipitation levels, and other atmospheric conditions over time. Climate scientists work in various settings such as universities, research institutions, government agencies, and private companies, and their main goal is to provide information that can help policymakers make informed decisions about climate change mitigation and adaptation strategies.
