Question

Quizplus · Accepted Answer

Global climate models (GCMs) project that the polar regions will experience a greater increase in temperature than the tropics. This is due to a phenomenon called polar amplification, which occurs because snow and ice reflect sunlight back into space, but as the temperature warms, more of that sunlight is absorbed, leading to further warming. This positive feedback loop leads to greater warming in the polar regions than in other parts of the world.
