How can human activities impact climate change?

• A. Emissions of greenhouse gases trap heat, altering global climate patterns
• B. Humans have no effect on climate
• C. Deforestation cools the climate permanently
• D. Human activity only affects weather, not climate

Answer: (A)

Human activities influence climate by increasing greenhouse gas concentrations in the atmosphere, which traps more heat and changes global climate patterns. When we burn fossil fuels for energy and transport, and when industry and agriculture release gases like carbon dioxide, methane, and nitrous oxide, these gases form a thicker blanket around Earth. That extra blanket slows the escape of heat back into space, warming the planet and shifting patterns of temperature and precipitation, intensifying storms, and causing ice to melt. This explains why the statement about greenhouse gas emissions trapping heat and altering global climate patterns is the best choice. The idea that humans have no effect contradicts scientific evidence; deforestation doesn’t cool the climate permanently and often contributes to warming by releasing stored carbon; and human activity influences not just weather in the short term but the long-term climate as well.
