What is the result of increased CO2 levels on Earth's average temperature?

The result of increased CO2 levels on Earth's average temperature is most accurately described by the term "Global Warming." When carbon dioxide concentrations in the atmosphere rise due to human activities, such as burning fossil fuels and deforestation, this leads to an enhanced greenhouse effect. This effect occurs because CO2 is a greenhouse gas, which means it traps heat from the sun within the Earth's atmosphere, preventing it from escaping back into space.

As a consequence, the additional CO2 results in a gradual increase in Earth's average temperature over time, contributing to what is referred to as global warming. This rise in temperature can lead to various environmental changes, including melting ice caps, rising sea levels, and more extreme weather conditions.

Understanding this relationship between CO2 levels and temperature is critical, as it underscores the impact of human activities on climate and the importance of taking measures to reduce greenhouse gas emissions to mitigate global warming. The other terms mentioned do not directly and specifically relate to the increase in Earth's average temperature due to CO2.
