So how does global warming come about? It starts with burning fuel. Since a huge part of the world uses carbon-based fuels in producing electricity, powering up industries, transporting people, and producing goods, then it follows that all of us who enjoy the fruits of these activities have a hand in the development of global warming. This is because burning carbon-based fuels emits harmful greenhouse gases. These emissions are called “greenhouse” because they work in the same way as actual greenhouses by trapping heat in the atmosphere. It is this same heat that causes the planet to warm up, hence the term global warming.
Is there anything wrong with a warmer Earth? The fact of the matter is that even the slightest change in average global temperatures is bound to yield negative effects. A warmer planet means warmer seas, which could result in more virulent typhoons. A warmer planet also means that the world’s glaciers are likely to melt, resulting in an increase in sea level. When this happens, low-lying islands, such as those in the Pacific, are bound to get eaten up by the ocean, displacing people and communities. Where will these people go? How will the world respond to this potential humanitarian crisis?

To this day, many groups still contest the notion of a planet experiencing rising temperatures. But their contention that there is no such thing as global warming is simply untenable because of mounting scientific evidence pointing out to the trend of rising temperatures in the world over the past few decades. Even a cursory look at the news would show more and more frequent abnormal weather and climatological patterns.
In the end, who is to blame for global warming? There is still an ongoing debate in certain quarters of whether or not human activities have exacerbated the problem or if global warming is purely the effect of natural forces. But this debate sounds trite in the face of numerous scientific studies and global warming essays that show the impact of human activities on the planet.
Ultimately, understanding what global warming is and what its effects are is crucial in implementing strategies designed to minimize the risks that come with it.
