The biggest cause of warming is climate change and environmental imbalances caused by human activities. Below are the main reasons:
Increase in greenhouse gases
Carbon dioxide CO2, methane CH4, and nitrous oxide N2O.
These gases trap the sun's heat in the Earth's atmosphere and increase the Earth's temperature.
The Deforestation of Forests
Trees absorb carbon dioxide. When trees are cut, this gas remains in the atmosphere and increases the heat.
At the same time, the decrease in greenery also reduces the natural power to keep the environment cool.
Industrialisation and increase in the number of vehicles
The smoke and gases emitted from factories and vehicles pollute the environment and increase the greenhouse effect.
Excessive use of fossil fuels such as coal, diesel and petrol
These are sources of energy, but burning them produces huge amounts of greenhouse gases.
Urbanisation
Due to the abundance of concrete, cement and roads, the heat of the earth is not able to escape at night, which causes the heat island effect. Temperatures are higher in urban areas than in rural areas. Also, using air conditioners and fridges on a large scale releases carbon monoxide which increases the radiation of the sun. Mainly because of the gases and energy consumption coming out of them.
Hazardous gases such as CFCs, HFCs
Chlorofluorocarbons (CFCs) are used in old refrigerators and ACs and Hydrofluorocarbons (HFCs) are often used in new ones.
When these gases leak, they are:
Damage to the ozone layer causes the sun's harmful UV rays to come directly to the earth.
Some HFCs have an impact 1000 times greater than CO2.
Higher power consumption
AC and fridge run on electricity and they consume a lot.
If this electricity is being made from coal or diesel, then it produces a huge amount of carbon dioxide which heats the earth.
Heat release - the emission of heat
AC and fridge cool the air inside, but release hot air outside, which further warms the surrounding environment.
4. Waste - Garbage and Risk of Leakage
When old ACs or fridges are thrown away, the gases present in them, if not destroyed properly, accumulate in the atmosphere and cause damage.
Disturbances in the natural balance
Drying up of water resources, soil erosion, and natural disasters are adding to the heat.
The result,
All of these factors are causing global warming - that is, the average temperature of the entire Earth is increasing, which makes it feel hotter every year and the weather is becoming unusual.
