How does human activity contribute to climate change?

Human activity contributes to climate change primarily through the increase of greenhouse gas emissions. Activities such as burning fossil fuels for energy, deforestation, and industrial processes release significant amounts of carbon dioxide, methane, and other greenhouse gases into the atmosphere. These gases trap heat, leading to a warming effect known as the greenhouse effect, which ultimately drives climate change. The rise in global temperatures impacts weather patterns, sea levels, and ecosystems.

While options related to biodiversity, sustainable farming practices, and reducing fossil fuel use have positive implications for the environment and can potentially mitigate climate change, they do not directly reflect the primary way human activities are contributing to climate change. Instead, the focus on greenhouse gas emissions highlights the critical role these emissions play in altering the planet's climate system.
