Climate change monitoring

Definition

Climate change monitoring refers to the systematic observation and assessment of climate variables and indicators to track changes in the Earth's climate over time. This process involves collecting data on temperature, precipitation, sea level rise, and greenhouse gas concentrations, which can be used to evaluate trends, impacts, and the effectiveness of mitigation strategies.
