What kind of long-term data can remote sensing supply to aid in climate studies?

Remote sensing provides critical long-term data that is vital for climate studies, particularly when it comes to large-scale environmental changes. It can effectively monitor temperature changes over time, track sea level rise due to global warming, and provide visual evidence of glacial retreat as glaciers melt in response to rising temperatures. This data is collected from various satellites equipped with sensors that can capture thermal, optical, and radar information about the Earth's surface.

The other options do not contribute significantly to long-term climate data. Daily precipitation levels are important for weather analysis but do not give a comprehensive view of long-term climate trends. Changes in land ownership pertain more to social and economic factors rather than direct indicators of climate change. Urban traffic patterns are related to human activity and urban planning rather than environmental shifts in the climate system. Therefore, the temperature, sea level rise, and glacial retreat data supplied by remote sensing are crucial for understanding the ongoing effects of climate change and for informing policy and conservation efforts.
