What likely impact does an increase in CO₂ emissions have on the climate?

The increase in CO₂ emissions significantly contributes to the greenhouse effect, which is a natural process that warms the Earth. When CO₂ levels rise due to human activities such as burning fossil fuels, it enhances this greenhouse effect, trapping more heat in the atmosphere. This leads to increased global temperatures, a phenomenon known as global warming.

As the temperature of the Earth rises, it can result in various changes to climate patterns. This includes more frequent and intense extreme weather events such as hurricanes, droughts, floods, and heatwaves. Higher temperatures can cause changes in precipitation patterns, leading to heavier rainfall in some areas and prolonged dry conditions in others. These factors contribute to the overall increase in climate variability and extreme weather events, making option C the most accurate reflection of the implications of rising CO₂ levels.

The other choices misrepresent the relationship between CO₂ emissions and climate effects. For instance, the notion that an increase in CO₂ leads to less extreme weather contradicts established scientific understanding. Similarly, proposing that there is no significant effect overlooks the extensive research demonstrating how CO₂ emissions are linked to measurable climate change. Lastly, the idea that increased CO₂ could result in decreased average temperatures is contrary to the evidence of rising global temperatures associated with higher greenhouse gas
