Understand the Problem
The question is asking for the main cause of current global warming among several options, specifically focusing on factors like glacier melting, solar activity changes, volcanic activity, and increased carbon dioxide concentration.
Answer
Increase in the concentration of carbon dioxide in the atmosphere.
The final answer is the increase in the concentration of carbon dioxide in the atmosphere.
Answer for screen readers
The final answer is the increase in the concentration of carbon dioxide in the atmosphere.
More Information
The increase in carbon dioxide, primarily due to human activities like burning fossil fuels, is the main cause of current global warming. Carbon dioxide is a major greenhouse gas, which traps heat in the Earth's atmosphere.
Tips
A common mistake is to confuse the factors contributing to climate change with symptoms or results, like melting glaciers, instead of focusing on root causes.
