The main reason for the sudden climate change in recent times is primarily due to human activities, particularly the burning of fossil fuels such as coal, oil, and gas, which release large amounts of carbon dioxide (CO2) and other greenhouse gases into the atmosphere. This is known as anthropogenic global warming.
Here are some key factors contributing to climate change:
Since the over exploitation of resources that cause pollution such as coal (in energy generation), CFC’s (in air conditioning systems) and increase in deforestation and sudden increase in mass forest burn is the main reason for sudden climate change. But in recent time use of war heads also led to the climate change.
According to the reports, there have been increase in consumption of electricity in recent times which increased overall use of coal for the production of electricity. Due to sudden increase in climatic temperature in most part of the world has increased the use of air conditioning system that also produced CFCs which also gave a thrust to the increasing pollution which gave a boost to climate change.
Also, in recent times, some countries used too many war heads that also contributed in increasing overall temperature which led to climate change.
The dense forest areas which once played important role in climate change control have been heavily impacted due to deforestation. Also there has been very few afforestation that has decreased forest cover.
The overall increased in temperature result in delayed monsoon(in case of India), as irregular cyclones resulted in changing the weather pattern in recent years.
The phenomenon of climate change is not new but it has accelerated due to human needs and development. While the course of climate change has been the result of the Industrial Revolution over several decades. Natural processes such as changes in the Sun’s energy and volcanic eruptions also affect the Earth’s climate.
Here are the main reasons for climate change in recent times:
1. Greenhouse Gas Emissions: The burning of fossil fuels emits large amount of GHGs such as Carbon-dioxide(CO2), methane (CH4), nitrous oxide (N2O), CFCs and HFCs. These GHGs emissions caused Earth’s temperature to rise and subsequently lead to global warming.
2. Deforestation: Clearing forests for urban development, agriculture and logging reduces the number of trees that can absorb CO2, thus increasing carbon footprint.
3. Rapid Industrialization: Since Industrial Revolution, human activities have contributed enormously to concentration of GHGs through manufacturing processes and energy production for making goods.
4. Urbanization: The rapid growth of urban cities has often lead to increased energy consumption and emissions from vehicles, heating and cooling systems.
These human- induced factors have hastened the rate of climate change leading to warming of Earth’s surface. Collective efforts are required from governments and individual to reduce the global increase in GHGs.
