Answer:
B. Melting polar ice caps
Explanation:
The global climate change is one of the most popular themes in the past few decades. It is a natural process that has been constantly happening on Earth, with periods of cooling down, or periods of warming up. In more recent times, the humans also started to contribute slightly to this process with the emissions of the greenhouse gasses, which are making the atmosphere warmer.
With the temperatures gradually rising on global level, there are numerous changes occurring. One of the most noticeable changes is the melting of the polar ice caps. Little by little, the polar ice caps and the glaciers are melting, thus decreasing the area occupied by frozen surface on the planet.
While it is almost impossible for the entirety of the ice caps to melt down until there is a large land mass on the poles, or one of them, it is most certain that the ice caps will reduce significantly. If the trend continues it will probably be only the interior of Antarctica that will preserve an ice cap.
