What will be the effect of global warming at poles
Answers
Answer:
The increasingly dense blanket of greenhouse gases is trapping heat and taking its toll on the planet, especially at the poles. ... Without sea ice, Earth wouldabsorb more solar radiation—and our climate would be even warmer. Many animals also depend directly on sea ice.
Explanation:
The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s.Related impacts include ocean circulation changes, increased input of freshwater, and ocean acidification. Indirect effects through potential climate teleconnections to mid latitudes may result in a greater frequency of extreme weather events (flooding, fires and drought), ecological, biological and phenology changes, biological migrations and extinctions, natural resource stresses and as well as human health, displacement and security issues. Potential methane releases from the region, especially through the thawing of permafrost and methane clathrates, may occur. Presently, the Arctic is warming twice as fast as the rest of the world. The pronounced warming signal, the amplified response of the Arctic to global warming, is often seen as a leading indicator of global warming. The melting of Greenland's ice sheet is linked to polar amplification. The warming in the Arctic is primarily caused by human-caused emissions of greenhouse gases such as carbon dioxide, methane, and nitrous oxide.
