Answer: С . The temperature increases by about 12°C and then decreases by about 12°C.

Explanation:

Temperatures around the world have been on the rise since the Industrial revolution as humans clog the planet with Carbon Dioxide and other pollutants. This had led to a rise in temperatures that has seen ice levels fall and sea levels rise around the world.

Temperature fluctuations on the other hand are not a new thing. Studies show that in Antarctica temperatures from about 440,000 years ago to about 340,000 years ago increased by 12°C and then decreased by about 12°C.

Answer:

C. The temperature increases by about 12°C and then decreases by about 12°C.

Explanation:

The attached shows ice core data that indicates the time period of interest was about the period of one full cycle of climate change. Temperature went up, then went down again to about its original level. The range of change was on the order of 12 °C.
