Question

As Earth warms:
• Ice cover melts, exposing soil or water
• Albedo (Reflectivity of sunlight) decreases
• More energy is absorbed by Earth's surface
• Global temperature rises
• More ice melts

IS THIS A NEGATIVE OR POSITIVE FEEDBACK LOOP AND WHY?

Answer 1

it’s negative because eventually all of the ice will melt and many countries will be covered in water due to too much heat in the atmosphere

Answer 2

it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface.

Is there an albedo increase or decrease when ice melts?

Note that in global warming, there is a rise in feedback when there is reflective ice (that is, one has a higher albedo) when compared to land or water surfaces.

Conclusively, it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface and thus cause an albedo effect.
