Dismaying Signs Showing the Impact of Climate Change on the Arctics

The polar regions are melting fast, the sea levels are rising steadily and many inhabited places around the world have been defunct by now due to catastrophic climate conditions. Numerous research and surveys have been conducted in the Arctics to evaluate how fast its environment is deteriorating, thereby becoming unfavourable for polar living species.

A steep and steady rise in average temperature of the Arctic region has been noticed by researchers and the aftereffects have already become loud and clear for the whole world. Recently, an integrated assessment has been conducted by a team of 90 scientists who have scooped out some of the striking findings on effect of climate change and global warming on the Arctic landscape and ecosystem.

Some of the findings probed by the Arctic Monitoring and Assessment Program initiated by the Arctic Council, that is being represented by eight circumpolar nations are hereby stated.

● The Arctic Region is about to become almost free of ice during the summers by 2030 or even before that as well.

● Walruses, seals and polar bears which, are highly dependant on ice for their existence are confronting elevated stress and disruption.

● Climatic changes encountered by the Arctic region might affect the weather of distant regions as far as away of the Southeast Asia.

● The average temperature is rising twice as fast as possible compared to rest of the world. As reported, the Arctic temperature was around six degrees higher than average during 2016.

● The defrosted permafrost has already started affecting the Northern infrastructure by releasing huge amounts of methane into the environment.

Degrading ecosystem

The gradual decline in extent and thickness of sea ice along with the duration of ice melt are taking a great toll on the marine ecosystems and biodiversity. Some of its core implications are the change in range of Arctic species, increased occurrence of algal blooms, change in food habits of marine mammals, changing predator-prey relationships, migration patterns and habitat usage.

Climate trends of the Arctic Ocean affect carbon emissions and storage

Recent findings have also stated that near about 50% of the total amount of soil carbon in the world is equipped with the Arctic soils. As the thawing permafrost is significantly contributing to future carbon and methane emissions, the atmospheric concentration of greenhouse gases is about to increase to a great extent.

Unfreezed Water during Winter

Scientists have reported that they have observed moderate level of open water during the winters in the Arctic ocean, much like the Atlantic side. They stated that the Atlantic water is penetrating into the Arctics which, is further upwelling towards base of the sea ice underneath, where it has already started melting. Open water has started affecting the weather patterns. The heat released from open water has resulted in a stipulated rise in the heat present in the atmosphere. This, in turn, is degrading the strength of the polar vortex.

Polar vortex is known to be the channel of powerful winds in between the warm moist air mass of the farther South and cold dry air of the North Pole. Since it is weakening over the gradual passage of time, it is disintegrating into a sequence of fragments submerging up and down, fetching warm air north and cold air south.

Governments have already started making considerable cuts to the greenhouse gas emissions to prevent the dreadful impact of climate change and global warming. Though the world has already suffered from severe environmental issues, however, a set of progressive approaches, methods and result-driven interventions have been initiated by now, thereby taking a step towards promoting sustenance.
