The two correct answers regarding the effects of melting sea ice are:
1. **The exposed water absorbs more thermal energy from the sun than did the ice.**
2. **The exposed water can radiate more heat to the atmosphere than it could when insulated by the ice cover.**
Melting sea ice reduces the Earth's albedo (reflectivity), leading to more heat absorption, while also impacting heat exchange with the atmosphere.
