Answer

Main Body

Due to global warming initiated by increase in greenhouse gases (over 430 ppm of CO2) has led to melting of Arctic ice.

Potential consequences of Arctic ice melt:

Biodiversity:

Reduction in shelter and home for biodiversity

Extinction of species due to inability to survive.

Migration of some species to other areas.

(Eg) Polar bears have reduced to less food resourced and declining ice cover.

Ecosystem:

Extinction of key species - leading to present ecosystem collapse

Development of new traits in some species to adopt to changes

New ecosystem will emerge.

(Eg) Migration of some species of tropical and temperate areas to Arctic regions.

Overall, loss of biodiversity and ecosystem change will occur.

This will impact the global ecological balance in several ways:

Reduction in Arctic icechange in wind patternchanging ocean currents

Change in upper air circulation in polar regionmeandering of polar vortx

Change in climate of places all over the worlddisrupt ecological balance

According to IPCC 6th AR, Arctic will have no ice in summer by 2050.

Changes in arctic ice melt will have huge impact as global ecological balance disrupting biodiversity. Urgent actions to fulfill NDCs under Paris Agreement are necessary.
