Question

multiple choice 2 points what is the main source of carbon dioxide emissions that contribute to global warming? ocean currents burning fossil fuels plant respiration volcanic eruptions

Explanation:

Ocean currents do not emit carbon dioxide. Plant respiration is a natural process and part of the carbon cycle, not a major contributor to the increase in CO₂ for global warming. Volcanic eruptions release CO₂ but on a much smaller scale compared to human - related activities. Burning fossil fuels (coal, oil, gas) by humans for energy production, transportation, etc., is the main source of anthropogenic (human - caused) carbon dioxide emissions that contribute to global warming.

Answer:

B. Burning fossil fuels
