Declining arctic sea ice is a component of enhanced climate change, impacting the lives of people. As the arctic sea ice melts it will form several positive feedback loops such as decreasing albedo, thawing permafrost, and increasing ocean levels. This contributes to an overall increase in global average temperatures, creating countless changes to our planet.
The melting of arctic ice reduces salinity of the adjacent oceans and this “causes a cessation of deep convection and a climate state with decreased oceanic heat transport, decreased high-latitude atmospheric temperature, and larger sea ice extent”
Sea ice cover in the Earth’s arctic regions is threatened by human induced climate change
