Climate change is accelerated by the reduction of global snow and ice cover.
Correct Answer
A. True
Explanation
The reduction of global snow and ice cover contributes to the acceleration of climate change because snow and ice reflect sunlight back into space, which helps to cool the Earth's surface. When snow and ice melt, they expose darker surfaces like land and water, which absorb more sunlight and increase the overall temperature. This phenomenon, known as the albedo effect, leads to further melting and warming, creating a positive feedback loop that amplifies climate change. Therefore, the statement "Climate change is accelerated by the reduction of global snow and ice cover" is true.
