what is global warming

  1. Meaning of Global Warming

Global warming refers to the gradual increase in Earth’s overall temperature.

It happens due to the excessive accumulation of greenhouse gases in the atmosphere.

These gases trap heat and prevent it from escaping into space...Read More

  1. Greenhouse Effect (Main Cause)

The greenhouse effect is a natural process that keeps Earth warm.

Sunlight enters Earth’s atmosphere.

Some heat is reflected back, but greenhouse gases trap the remaining heat.

Human activities have intensified this effect, causing overheating...Read More

  1. Major Greenhouse Gases

Carbon Dioxide (CO₂) – released from burning fossil fuels

Methane (CH₄) – from agriculture, livestock, and landfills

Nitrous Oxide (N₂O) – from fertilizers and industrial processes

Chlorofluorocarbons (CFCs) – from refrigerators and air conditioners...Read More

  1. Causes of Global Warming

Burning of Fossil Fuels

Coal, petrol, diesel release large amounts of CO₂.

Deforestation

Trees absorb CO₂; cutting them increases carbon levels.

Industrialization

Factories emit greenhouse gases.

Agriculture

Methane from cattle and rice fields.

Urbanization

Increased energy use and waste generation...Read More

  1. Effects of Global Warming

Rising Global Temperatures

Hotter summers and warmer winters.

Melting of Glaciers and Polar Ice

Leads to rising sea levels.

Sea Level Rise

Coastal flooding and loss of land.

Extreme Weather Events

Heatwaves, droughts, floods, cyclones.

Impact on Wildlife

Loss of habitat and extinction of species.

Human Health Problems

Heat strokes, spread of diseases...Read More

  1. Impact on India

Increased heatwaves and water scarcity.

Irregular monsoon patterns.

Melting of Himalayan glaciers.

Threat to agriculture and food security...Read More

  1. Measures to Control Global Warming

Use Renewable Energy

Solar, wind, hydro power.

Afforestation

Plant more trees.

Reduce Fossil Fuel Use

Use public transport, electric vehicles.

Energy Conservation

Switch off unused appliances.

Reduce, Reuse, Recycle

Minimize waste.

International Cooperation

Agreements like the Paris Climate Agreement...Read More

  1. Difference Between Global Warming and Climate Change

Global Warming → Increase in Earth’s temperature.

Climate Change → Long-term changes in weather patterns caused by global warming...Read More

  1. Conclusion

Global warming is a serious global issue affecting life on Earth.

Immediate and collective action is needed to protect the environment.

Small steps by individuals can make a big difference...Read More
