Question

Over the last ~100 years, greenhouse gases have increased, thereby decreasing the effective emissivity of the Earth from 0.6 to 0.5986. How much would the Earth's temperature change simply due to this decrease in emissivity?

a. cool by 0.1 -0.2 K
b. cool by 0.0 -0.1K
c. change by <0.01K
d. warm by 0.1 -0.2 K
e. warm by 0.5 - 1.0K

Answer 1

d. warm by 0.1 - 0.2 k

Step-by-step explanation:

The earth global warming is increasing everyday due to the pollution. The effective emissivity is the ability to emit energy from the surface in the form of radiations. The earth's effective emissivity is declined by 0.6 to 0.5968. The change is due to the green house gases that are increased which has led the temperature of earth change by 0.1 to 0.2k warmer.
