Over the past century, we, the humans have changed the earth’s atmosphere in dramatic ways resulting in global warming. At present, it’s the most controversial environmental issue. Global warming severely affects the natural balance of the environment and, as a result, the climate has gone through unwanted changes throughout the world.
The exchange of incoming and outgoing radiation that warms the earth surface is often referred to as the greenhouse effect because a greenhouse works in the same way. Indiscriminate use of fossil fuels, cutting down of the trees in abundance (deforestation) along with other factors have raised the percentage of greenhouse gases like CO2, methane, nitrous oxide and fluorinated gases in the atmosphere.
These gases trap sun’s radiation and the temperature of the earth surface increases. As air moves around the world, greenhouse gases become globally mixed, causing the glaciers melting which eventually raises the sea level. This could result in the flooding of low-lying coastal areas and cities, such as Egypt, the Netherlands, and Bangladesh. Many areas of the world are experiencing increased hurricanes, floods, droughts, and other natural disasters. It also affects the aquatic and marine life of plants and animals. Damage in the ozone layer is the most threatening effect of global warming.
The impact of the increasing global warming could be extremely harmful. Apart from torrential rains causing floods, drought, forest pests and wildfires are happening. This abrupt change of temperature in different parts of the earth is making the water of the oceans warm. As a result of this, almost in every mountainous region across the world, glaciers are retreating. In one basin in Glacier National Park in Montana, for instance, two-thirds of the ice has disappeared since 1850. If we can’t put a check on uncontrolled warming, the remaining glaciers could disappear by 2030.
Global warming is no more a prediction or threat, it is happening, right now! And, the impact of the process on this planet is getting worse with every passing day. Humanity doesn’t have much time left. We should start working immensely on stabilizing the concentration of greenhouse gases to thwart devastating effects from climate change.
Small changes in everyone’s life can help to check global warming. Indiscriminate use of vehicles and machines producing gases like CO2 should be restricted, Co2 emission being one of the major factors of global warming. Instead, renewable and non-conventional energy sources like the wind, solar and hydel energy should be given preference. People should be advised to plant more and more trees as trees maintain the natural ecological balance. There should be well-planned and environment-friendly drainage system to pass away the waste products and chemical wastages from mills and factories.
The earth has its own natural balance. To make life thrive on the earth surface, we need to maintain it. Or else, humankind would be in great danger in the near future. By following easy and simple steps, we can be able to stop the huge negative changes in the atmosphere by lessening the effects of global warming and even stop it a day.
