Today’s Hindu Editorial Analysis of ‘Antarctic sea ice cover hits many record lows’ discusses decreasing ice cover in Antarctic sea ice cover over period of time. Antarctic Sea Ice Cover Hits Many Record Lows article is analysed in detailed.
A recent report indicates that the extent of sea ice in Antarctica has reached its lowest recorded level. The concerning trend continues, as global temperatures rise, leading to a reduction in sea ice cover.
Antarctica experiences a cycle where sea ice melts during its summer season, occurring from approximately October to March, and subsequently freezes again during the winter months.
Over the past six years, data reveals significant declines in the coverage of Antarctic sea ice. This accelerated melting of sea ice contributes to the elevation of global sea levels, presenting a significant risk to coastal cities.
The substantial reduction in ice cover has far-reaching consequences, impacting global weather patterns and underwater ecosystems.
As global temperatures continue to rise, the Antarctic region has experienced elevated air temperatures this year. The reduction in sea ice coverage contributes to a greater absorption of the sun’s heat by the darker-colored ocean, as less of it is reflected back. This phenomenon is known as the ice-albedo feedback cycle, where heat becomes trapped.
While ice does regenerate during the winter months, the newly formed ice tends to be thinner compared to the multi-year ice, resulting in a more delicate and vulnerable state for the overall surface area of Antarctica.
