Climate Change – A Brief Overview

The term climate change has gained more usage in the last few decades when more and more concerned citizens become acutely aware of the changes in climate that are happening in their area. Many believe that the changes in the climate are direct consequences of human activities that have boomed over the last century. Here’s a quick look at what is climate change.

So what exactly is climate change? When people are talking about climate change, they’re talking about exactly that – the changes that happen in the climate. These changes are caused when natural processes like volcanic eruptions or the cyclic changes in solar activity give direct impact to the climate system. However, it is a general consensus now that the recent climate change is caused by human activities.

Are we really causing climate change? The climate has changed throughout the history of the world – the ice age showed us that. However, with the increase of industrial activities by human in the past century or so, climate change has been attributed to human activities. Burning of fossil fuels, increasing number of coal-fired power stations and major deforestation all contribute to the release of greenhouse gas. This gas forms a blanket over the Earth and traps heat, causing average temperature to increase and therefore warming certain parts of the world.

Is climate change that bad? If unaddressed, yes. Climate change will cause excessive heat on the Earth’s surface. This in turn will melt glaciers and causes sea level to rise, flooding lower landed areas. There will be more carbon dioxide content in the air and this can affect the natural make up of crops and plants’ growth, throwing it out of scale.

Scientists around the world are working hard in addressing climate change so that it can be contained and not disrupt the Earth’s natural temperature and balance.
