Which of the following is a direct consequence of greenhouse gas emissions from burning fossil fuels?

The increase in greenhouse gas emissions, particularly carbon dioxide and methane from burning fossil fuels, leads to an enhancement of the greenhouse effect. This effect occurs when these gases trap heat in the Earth's atmosphere, which in turn results in higher global temperatures. As the concentration of greenhouse gases rises, it causes more heat to be retained, contributing to global warming and climate change.

Increased global temperatures can cause a range of effects, including altered weather patterns, melting ice caps, rising sea levels, and severe impacts on ecosystems and biodiversity. While other factors can also influence ozone levels, soil nutrients, and biodiversity, the direct consequence of increased greenhouse gas emissions from fossil fuels is the rise in global temperatures.
