Global Warming is defined as the rise in temperature of the earth’s atmosphere due to the excess release of greenhouse gas in the environment. These greenhouse gases generally include gases like Carbon dioxide, Carbon monoxide.The human population is growing we are capturing more land by cutting trees. As the number of trees decreases they inhale less Carbon dioxide. The main reasons of global warming are industrialization, globalisation, deforestation and excessive use fuels which leads to Carbon Emissions.Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally this radiation would escape into space, but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter.
Disappearing glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and continue to increase the risk of wildfires in the American West.
Forests, farms, and cities will face troublesome new pests, heat waves, heavy downpours, and increased flooding. All of these can damage or destroy agriculture and fisheries.
Allergies, asthma, and infectious disease outbreaks will become more common due to increased growth of pollen-producing ragweed, higher levels of air pollution, and the spread of conditions favorable to pathogens and mosquitoes.There are several causes of global warming, which have a negative effect on humans, plants and animals. These causes may be natural or might be the outcome of human activities. In order to curb the issues, it is very important to understand the negative impacts of global warming.
Man-made Causes of Global Warming:
Plants are the main source of oxygen. They take in carbon dioxide and release oxygen thereby maintaining environmental balance. Forests are being depleted for many domestic and commercial purposes. This has led to an environmental imbalance, thereby giving rise to global warming.
Use of Vehicles:
The use of vehicles, even for a very short distance results in various gaseous emissions. Vehicles burn fossil fuels which emit a large amount of carbon dioxide and other toxins into the atmosphere resulting in a temperature increase.
With the excessive use of air conditioners and refrigerators, humans have been adding CFCs into the environment which affects the atmospheric ozone layer. The ozone layer protects the earth surface from the harmful ultraviolet rays emitted by the sun. The CFCs has led to ozone layer depletion making way for the ultraviolet rays, thereby increasing the temperature of the earth.
Natural Causes of Global Warming:
Volcanoes are one of the largest natural contributors to global warming. The ash and smoke emitted during volcanic eruptions goes out into the atmosphere and affects the climate.
Water vapour is a kind of greenhouse gas. Due to the increase in the earth’s temperature more water gets evaporated from the water bodies and stays in the atmosphere adding to global warming.
How Can We Stop Global Warming?
Recycle more. The aim is to cut down the amount of carbon dioxide released in the environment.
Switch to renewable energy.
Use energy-efficient devices. Use less hot water.
Turn off electronic devices.
