Question Q7What are the potential consequencesGS1GS2

What are the potential consequences of Arctic ice melt on biodiversity and ecosystems? How might these changes impact global ecological balance?

Open scan (p.13)

Introduction

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

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.

(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 unfract 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

[Diagram showing ARCTIC region with 'weakening of upper air circulation is disrupting normal weather pattern' and connection to INDIAN OCEAN]

According to IPCE 6th AR, Arctic will have no ice in summer by 20 50.

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