</s><s>Assistant: Global warming is a pressing issue that has significant impacts on various regions of the world, particularly the polar regions. The melting of glaciers and icebergs has been a direct result of global warming, which has significant consequences. As the ice melts, the polar ice caps shrink, leading to a rise in sea levels. This rise in sea levels has the potential to inundate coastal cities and island nations, posing a significant threat to their existence. Additionally, the melting ice has disrupted the natural habitats of various animal species, leading to the extinction of several of them. These include polar bears, walruses, seals, and other animals that rely on the polar ice cap for survival. The devastating loss of these wild animals is a direct consequence of global warming, and it is a telling reminder that we need to take swift and decisive action to curb this issue.
