Which of the following is a consequence of increased greenhouse gas emissions?

Rising global temperatures result from increased greenhouse gas emissions due to the greenhouse effect. Greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere, preventing it from escaping into space. This process leads to an increase in the average global temperature over time, contributing to climate change.

As the concentration of greenhouse gases continues to rise due to human activities like burning fossil fuels, deforestation, and industrial processes, the enhanced greenhouse effect exacerbates warming trends. The implications of rising temperatures are extensive, leading to various environmental issues, including melting ice caps, rising sea levels, and more frequent extreme weather events.

In contrast, decreased global temperatures, increased polar bear populations, and more stable climate patterns do not accurately reflect the current scientific understanding of the impacts of greenhouse gas emissions. Instead, they misrepresent the relationship between emissions and climatic outcomes.
