However, human activities are now increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural warming caused by the greenhouse effect. During the Industrial Revolution, humans began burning coal, natural gas, and oil to power machines for manufacturing and transportation.
For many years I have been a skeptic of global warming because the climate record available to assess the effects of increased carbon dioxide emission has been too short to say with confidence that the effect is real.t is unclear whether global warming is due to increased carbon dioxide concentration or if carbon dioxide concentration is the result of global warming.
