What is global warming?
Exam-ready answer • 02 Mark
✓Answer
Global warming is the gradual increase in Earth’s average surface temperature due to the buildup of greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), in the atmosphere. These gases trap heat from the sun, causing a rise in temperature, which leads to climate changes like melting ice caps, rising sea levels, and more extreme weather patterns.
