The earth is warming up at a steady pace. The temperature of the globe is increasing. The average global temperature has increased by about 0.8 degrees Celsius (1.4 degrees Fahrenheit) since 1880 and it will rise an additional 0.3 to 0.7 degree Celsius through 2035 as per environment scientist. The reason for this is the increase in human-caused greenhouse gases, which has led to health, ecological and humanitarian crises.
Global warming has often been described as one of the most serious environmental problems and every living creature is affecting very badly. The main cause of Global Warming is an increment of Carbon Dioxide (CO2) in our atmosphere and this Carbon Dioxide increases due to greenhouse gases as greenhouse gases are generated by burning fossils fuels (Oil, Coal and Natural Gases) as a power plant, factories, and automobiles. Although it is not easy to reduce Global Warming but it is not impossible also. There are many ways to control Global Warming in our hands because the main driver behind global warming is human activity. Yes, human activity is the main driver. If we all are the main driver then we should have the keys also. But before finding the keys, let’s discuss the main causes/reasons for climate change.
Causes of Global Warming:
Too much carbon dioxide (CO2) in the atmosphere is the main cause of Global Warming. CO2 is acting as a blanket of the earth which trapping heat and warming the planet. Methane (CH4) and Nitrous Oxide (N2O) are also cause as it generates due to waste management and agricultural practices.
Here we will discuss in detail about the causes of Global Warming.
Burning fossil fuels:
Fossil fuel is the first and main source of global warming. Burning coal, oil and natural gases for power plants generate CO2 and generate Nitrous Oxide (N2O) which is increasing the temperature of the globe. CO2 is the most common greenhouse gas. Beginning of the industrial revolution, its presence in the atmosphere amounted to about 280 parts per million (ppm). Today, it’s about 400 ppm. (This number means there are 400 molecules of carbon dioxide in the air per every million air molecules). CO2 is most commonly produced by human activities and it is responsible for 64% of man-made global warming, Methane is responsible for 17% and nitrous oxide for 6%.
The exploitation of forests has a major role in climate change as trees help to regulate the climate by absorbing CO2 from the atmosphere and releasing oxygen back into it. The forest area is reducing and the level of CO2 is increasing due to many activities. Both activities are just the opposite for environment and the result is global warming. When trees are cut down, this positive effect is lost and the carbon stored in the trees is released into the atmosphere. Up to one-fifth of global greenhouse gas pollution comes from deforestation and forest degradation.
Increasing livestock farming:
Livestock animal-like Cow, Buffalo, Sheep, etc. produce large amounts of methane, a greenhouse gas when they digest their food. This methane gas also a major contributor to global warming.
In intensive farming, farmers are using some plant protection products and fertilizers. These products produce large number of nitrous oxide, a greenhouse gas, that also a major contributor to global warming.
Waste disposal also a major reasons for global warming. Waste management methods like landfills and incineration emit greenhouse and toxic gases including methane that are released into the atmosphere, soil, and waterways.
How to Control Global Warming?
- Move away from fossil fuels and redirect to renewable energies like solar, wind, biomass and geothermal.
- Prevent deforestation and tree-clearing. Plant more and more trees around us.
- Produce clean energy and use more efficient devices (e.g. LED light bulbs, innovative shower systems) to save energy.
- Promote public transportation and carpooling.
- Use Electric Vehicles; will help to reduce CO2 emissions.
- Encourage for organic crops and no use of fertilizers.
- Adopt the best waste management system.
If we adopt all the above points, we can control global warming and even I would say, we can stop global warming as these are not difficult or impossible tasks. It is our moral duty to save our environment. It is good to be a friend of nature. If we will try to play with nature and the environment, nature will come back with droughts, floods, lightning, wildfires, etc.
