Which of the following is NOT a result of the greenhouse effect?

a. the greenhouse effect keeps the earth from becoming too cool at night

b. the greenhouse effect makes it possible for the earth to support life

c, the greenhouse effect is making the earth too hot to support life

d. the greenhouse effect keeps the earth from becoming too hot durning the day

The answer should be D.

Greenhouse effect is where greenhouse gases like carbon dioxide or ozone absorbs some of the heat in the atmosphere that are released by the sun, and trap these heat inside the atmosphere so that the Earth is kept warm and less heat is reradiated back to the space.

A is true because the heat trapped can prevent the temperature becoming too low especially when the sun is not present at the moment.

B is also true because greenhouse effect is a natural process and it prevents the Earth becoming too cool to support life.

C is also true because nowadays, especially when urban activities releases so much greenhouse gas, that the greenhouse effect is intensified and it is really making the Earth too hot. For example the ice sheets from polar regions are melting that it destroyed a lot of habitats and some species became endangered or even extinct.

Therefore, D should be the correct answer. The greenhouse effect is actually making the Earth become hotter and hotter. The global temperature even rose around 1 degree in the past decades.
