What’s Global Warming?

Global Warming is one of the rising environmental issues. It is the process of the increasing average air temperature close to the surface of the Earth in the last 1 to 2 centuries. Since the middle of the 20th century, climate scientists have collected detailed data on different phenomena related to weather occurrences (such as temperature, precipitation, and storms) as well as these effects on the climate (such as the ocean’s currents and the atmospheric chemical makeup).

These observations show that the Earth’s climate has altered nearly every possible period from at least the start of geologic time. Human activities from the beginning of the Industrial Revolution have been influencing the speed and intensity of current changes in the climate.

What causes Global Warming?

Greenhouse gases are the root cause of global Warming. These are emitted when fossil fuels such as coal, oil, and natural gas are burned. They are also released by industrial processes and agriculture. Carbon dioxide (CO2) is the main greenhouse gas formed by human activity. It is accountable for approximately 80% of the total greenhouse effect. Other significant contributors include methane (CH4), nitrous oxide (N2O), (and CFCs).

The impact of a greenhouse gas on the environment is determined by its duration, global warming potential, and quantity. Here we will discuss some human activities that contribute warming of the globe.

Solid fuel and biomass combustion for heating and cooking

In every country, families are burning a broad assortment of solid fuels and biomass for cooking, heating, and cooking, such as charcoal, wood, animal dung, and agricultural waste. They are typically used for cooking in stoves that use inefficient fuels or open fires, resulting in a greater demand for these items because of inadequate burning. Most community members are cutting down trees within nearby forests to get these items, which is known as deforestation.

When fewer trees exist, less carbon dioxide is removed from the atmosphere to become oxygen. The smoke released by this cooking and heating is hazardous for those who breathe it and the air outside. The smoke is a mixture of large quantities of carbon monoxide, carbon dioxide, and methane.


Manufacturing accounts for 21% of the greenhouse gas emissions in the world. It is responsible for climate change by releasing vast quantities of CO2 into the atmosphere. Certain governments have tried to mitigate the manufacturing industry’s impact by providing tax incentives for lower greenhouse gas emissions.

Other governments have also introduced caps and allowance trading systems. This kind of system works by imposing a maximum limit on emissions and allowing those low emitting levels of greenhouse gases to market their excess to big-emitting businesses.


Public, private, and freight transportation are essential to production, trade, and transport for people to travel and work. However, trains, aircraft, ships, and automobiles are responsible for 14% of the global emissions of greenhouse gases. Since they depend heavily on oil processed into gasoline, the discharges are very high. The gases released from combustion are the primary reason behind many environmental problems. When gasoline is burned, carbon dioxide and others greenhouse gases are released. The group will be led by private automobiles. Alternatives to fossil fuel-powered vehicles are becoming more common. Biofuels reduce emissions by as much as 80 per cent, fuel-efficient vehicles consume less gasoline, and electric cars aren’t powered by petroleum.


As per The World Bank, agriculture is one of the main drivers of climate change. It contributes between 19-29 per cent of the total greenhouse gases. Emissions will likely increase due to the need for increased food production to feed the world’s expanding population. Methane is a significant concern for environmental issues because the chemical is more than 26 times more potent than carbon dioxide. Animal and rice production causes too many methane emissions. Around 1/3 of the world’s agricultural methane emissions originate from livestock. Rice paddies grown are also a significant source of methane – approximately 11% of all agriculture’s methane emissions.

It’s hard to underestimate the forest’s importance. These are the home of various species of animals and plants; they are the source of food and medicine and support hundreds of thousands of workers. They’re also crucial in battling global Warming. Trees absorb carbon dioxide from the air, store it, and release oxygen when they perform photosynthesis. Wood is made almost entirely of carbon. By 2021, deforestation will account for just ten per cent of global warming emissions.

How Global Warming Affects us?

Global Warming affects humans, plants, and animals in several ways, including increasing ocean levels, droughts, and altered weather patterns. It is recognized by scientists worldwide as a significant human health issue and environmental threat. Below are some effects of global WarmingWarming on environmental quality.

Global WarmingWarming has two significant consequences:

  • Increase in global temperature of 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.
  •  Rising sea levels by at least 25 meters (82 feet) by 2100.

More information about the consequences of global WarmingWarming:

The rising global temperature is creating a wide range of modifications. The sea levels have been rising because of the ocean’s thermal mass expansion and the melting of the land glaciers. Quantities and patterns in which precipitation occurs are evolving.

Variations in rainfall and temperature patterns could increase the frequency, duration, and severity associated with other weather-related extremes like heat waves, floods, droughts, and cyclones. Other effects of global WarmingWarming are increased or lower income from agriculture, receding glaciers, a reduction in summer streams, and species disappearances.

What Can We Do To Stop Global Warming? 

Here are some solutions to global WarmingWarming that can help to overcome many environmental issues including global WarmingWarming:

  • We should reduce our carbon footprint. If we live in an urban area, we can reduce our energy usage at home. If we live in a rural area, we can plant trees and use solar power instead of electricity.
  •  We should support organizations that work towards reducing greenhouse gas emissions.
  •  We should vote for politicians who will change policies that encourage sustainable development.
  •  We should educate ourselves on environmental issues to share our knowledge with others.

The United Nations has declared 2015 that. We can do several things to national Year of Sustainable Energy for All. For example, we could turn off lights and appliances when we leave a room and avoid using plastic bags. Also, we could buy a reusable water bottle and refill it from a public fountain instead of bottled water. These simple steps are solutions to global Warming.

Another thing that we can do to fight climate change is to vote for politicians who support renewable energy sources such as wind and solar power. These energy foundations are clean and green because they do not emit harmful gases into the atmosphere. By educating yourself about the problem, you can become an advocate for environmental sustainability.
