Question

scientists estimate the global average temperature difference between an entirely glaciated earth and an ice - free earth to be

a 10°c
b 2°c
c 32°c
d 20°c

Explanation:

Scientists estimate the global - average temperature difference between an entirely glaciated Earth and an ice - free Earth to be about 32°C. This is based on climate science research considering factors like albedo (reflectivity) changes and the greenhouse effect. An ice - covered Earth reflects more sunlight, leading to a much colder climate compared to an ice - free Earth.

Answer:

C. 32°C
