Describe two effects of climate change on the polar regions?

Climate change has profound effects on the polar regions, with the Arctic warming twice as fast as the rest of the world. This rapid warming leads to significant reductions in sea ice, impacting marine ecosystems and indigenous communities dependent on these environments[1]. In Antarctica, the warming is about five times faster than the global average, causing ice shelves to collapse and contributing to global sea-level rise[2]. These changes not only alter the landscape but also have cascading effects on global weather patterns and biodiversity.
