Main Body

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.

(E) 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.

(E) 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 ice → change in wind pattern → changing ocean currents

↓ Change in upper air circulation in polar region → meandering of polar vortex

↓ Change in climate of places all over the world → disrupt ecological balance
