What tool gives scientists the best data to study the current loss of ice near the poles

Satellites provide scientists with the best data to study the current loss of ice near the poles. Specifically, satellites equipped with remote sensing instruments enable researchers to monitor the changes in ice cover and volume over time. These instruments can measure key parameters such as ice extent, thickness, and mass balance, providing a comprehensive understanding of the ice loss and its implications for the planet. The satellite data collected is crucial for tracking long-term trends, validating climate models, and informing policy decisions aimed at mitigating the impacts of melting ice.
