Concept: Environmental changes occurring due to human activities have led to a gradual rise in the Earth’s temperature. This phenomenon affects climate patterns and ecosystems worldwide.
Explanation: Global Warming refers to the gradual increase in the average temperature of the Earth’s surface due to the excessive accumulation of greenhouse gases in the atmosphere.
One major cause of global warming is the burning of fossil fuels such as coal, petroleum, and natural gas. The combustion of these fuels releases carbon dioxide (CO\textsubscript{2}), a greenhouse gas that traps heat in the atmosphere and leads to a rise in global temperatures.
Thus, global warming is the rise in Earth’s temperature mainly caused by greenhouse gas emissions, especially from the burning of fossil fuels.
