Which of the following statements is not based on climate change denial
Doss [256]

The correct answer is A.The climate is changing rapidly but it will be too expensive to fix.

Explanation:

Climate change involves important long-term changes in climate patterns as well as other features on land and bodies of water. This phenomenon has occurred naturally during the history of Earth; however, nowadays climate change has accelerated due to human activities that produce global warming and therefore the increase in temperatures and changes in climate.

Despite this, some deny climate change, which is known as climate change denial; this includes stating climate change does not exist, it is an exaggeration or a hoax, or considering it is the result of natural cycles. According to this, the only statement that is not based on climate change denial is "The climate is changing rapidly but it will be too expensive to fix" because in this statement the speaker recognizes climate change is real and considers it is a serious issue that might be difficult to solve.
