Introduction Arctic sea ice is melting at a rapid rate. According to NASA, sea ice has been reducing by 13% each decade since it started measuring this rate in 1979. But why does the loss of arctic sea ice matter? You probably don’t realise that arctic sea ice helps to regulate temperatures across the globe. Sea ice reflects about 80% of sunlight into space. This action balances the temperature across the planet.

Introduction While carbon dioxide (CO2) is essential for plant and animal survival, too much concentration in the atmosphere can have devastating consequences. CO2 has proven to be a significant contributor to air pollution, taking a substantial role in the greenhouse effect. That’s because carbon dioxide traps radiation at the ground level, resulting in ground-level ozone. That prevents the earth from cooling during the night and warms ocean waters. What Is Carbon Dioxide?

Introduction

Out of the 250 million people living by the coast globally, only less than 5 million are above sea level. Unfortunately, the global sea level has continued rising over the last century, and the rate has only increased in recent years. This rise in sea levels means that destructive storm surges will continue pushing further inland than ever before, resulting in frequent flooding.
