Quizplus · Accepted Answer

The scientific community has been aware of the potential impact of greenhouse gases on the planet since the early 19th century, when French mathematician and physicist Joseph Fourier first proposed the concept of the greenhouse effect. In the following decades, other scientists studied the role of carbon dioxide and other greenhouse gases in regulating Earth's temperature, and by the mid-20th century, concerns about human activities leading to increased greenhouse gas emissions were being raised. Therefore, climate scientists have been concerned about the effects of greenhouse gases on the sustainability of the planet for more than two centuries.
