Carbon dioxide is the most abundant greenhouse gas in the Earth’s atmosphere, responsible for about 76% of the total warming effect.

Ocean acidification is a process in which the pH level of seawater decreases due to the absorption of carbon dioxide from the atmosphere.

Coal is a non-renewable energy source, while solar and wind are renewable energy sources.

China is currently the world’s largest emitter of carbon dioxide, accounting for approximately 28% of global emissions.

The primary cause of global warming is the increase in greenhouse gases in the atmosphere, which is primarily due to human activities such as burning fossil fuels.

The primary cause of deforestation is human activities such as logging, agriculture, and infrastructure development.
