For example, the carbon dioxide level is currently about 400 parts per million (ppm). For the last 650,000 to about 1950, the carbon dioxide level never cross the 300 ppm level. However, with the increased use of fossil fuel, such as coal and gasoline, the carbon dioxide level began climbing to its current level. I am talking about fundamental science, such as climate change research, which should proceed without censorship or political agendas. However, politics in science should be confined to interpreting the results, not refuting results that have been widely established via the scientific method.
