Final answer:
Global warming's impact on polar ecosystems, sea levels, and urban areas.
Explanation:
Rising temperatures due to global warming can have significant effects on polar ecosystems. The increase in temperature leads to melting of glaciers and polar ice caps, resulting in a rise in sea levels and subsequent flooding of coastal areas. Additionally, the dissolution of the Antarctic ice sheet would impact the entire world by causing sea levels to rise, leading to potential flooding of urban centers and changes in agricultural production.
