Very few people will argue against the fact that the earth is getting increasingly warmer given the way summers are becoming hotter, the evidence that glaciers are melting, the sea levels are rising, and the way the weather in many parts of the world is increasingly becoming unpredictable.
All these characteristics of the weather can be summed up into one term, and that is global warming. It is only in recent decades that the idea of global warming is caused by humans has emerged. Environmental groups and governments worldwide began to take notice after scientists theorized that mankind, through certain activities, are actually changing the earth’s environment and climate. Even though the changes are taking place slowly, scientists warn that it could accelerate soon. They have even stated that in the present century, the 21 century, the earth will become warmer than it has been during the last four centuries.
Another cause of global warming is due to factors such as the relationship between the earth’s position, axis, revolution around the sun and rotation on its own axis.
Major volcanic eruptions have also been linked to natural global warming. The gradual changes that occur due to natural events are considered to take place very slowly, over several centuries. Most animal species survive these changes by migrating from one geographic location to another. Continue reading 5-Page Essay on Global Warming
