The average temperature of the surface of Earth has increased approximately 1°C in the past century. Which reason best explains this increase in temperature?

Question

a
higher levels of oxygen in the atmosphere
b
lower levels of ozone in the atmosphere
c
higher levels of nitrogen in the atmosphere
d
higher levels of carbon dioxide and other greenhouse gases in the atmosphere

Answer 1

The option that best explains the increase in Earth's average surface temperature is:

d. higher levels of carbon dioxide and other greenhouse gases in the atmosphere.

This increase in greenhouse gases, primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes, has led to an enhanced greenhouse effect, resulting in global warming.
