Science Journal Blog Entry Two What Happens If the Polar Ice Melts? Polar ice refers to sea ice, ice caps and ice sheets that remain frozen throughout the year (Encyclopaedia.com, n.d.; National Snow and Ice Data Center, n.d.). If the polar ice caps melt, it wouldn’t be good for our climate, ecosystems and lifestyle. On planet Earth, the Arctic and Antarctic consist of only ice, which is a balance to our ecosystem. The melting of ice sheets in Antarctica would cause a significant rise in global sea levels, which would result in potentially submerging coastal cities and dislocating millions of people worldwide. Also, if all polar ice were to melt, sea levels could increase by approximately 70 meters (National Snow and Ice Data Center [NSIDC], n.d.). Additionally, this would also lead to the loss of critical habitats for species such as polar bears, seals, and penguins, disrupting Arctic and Antarctic food chains and threatening biodiversity (World Wildlife Fund, n.d.).
