Answer
Both A and R are true and R is the correct explanation of A.
Explanation — The ice cover is indeed shrinking in regions like the Arctic, Antarctic, Alaska, and Greenland. This is mainly due to rising global temperatures, which are increasing at an alarming rate because of human activities such as burning fossil fuels, deforestation, and industrial pollution. These actions release greenhouse gases that trap heat in the atmosphere, leading to the melting of ice in polar and glacial regions.
