Which of the following have been changed or altered

due to climate change.

A. Droughts

B. Flooding

C. Melting of polar ice caps

D. All of the above

D.

Explanation:

Droughts come from an intense increase in temperature. This causes water/moisture to evaporate from the ground. This is caused by greenhouse gas emissions which makes things a lot warmer. Thus, the temperature rises.

C and B are linked. The icecaps melt which cause the water levels to rise. When the icecaps melt, the water goes into the ocean and causes a rising in the sea level, thus meaning floods can happen.

The answer is A. Because flooding isn't really caused by climate change
