A Correct answer
Explanation

Sea level rise is one of the most widely discussed and studied impacts of climate change, resulting from thermal expansion of seawater and melting ice sheets and glaciers. Deforestation and soil erosion are environmental problems but not direct climate change impacts, and they're less frequently discussed in climate change discourse than sea level rise.
