Question: Describe two effects of climate change on the polar regions?

Climate change has profound effects on the polar regions, with two significant impacts being the rapid warming and melting of ice. The Arctic is warming twice as fast as the global average, leading to the thawing of permafrost and the shrinking of sea ice. This not only affects the habitat of wildlife, such as polar bears, but also contributes to global sea-level rise as the Greenland ice sheet melts. In Antarctica, the warming is about five times faster than the global average, causing similar issues with ice melt and habitat loss. These changes disrupt ecosystems, affect indigenous populations, and have far-reaching consequences for the Earth's climate system. The polar regions act as a barometer for the health of our global environment, and the rapid changes there are a clear signal of the urgent need for climate action.
