Question:
I have heard that in the last couple hundred years, before the Industrial Revolution, that the carbon dioxide concentration in the atmosphere was higher than it is today. Why has not global warming and the runaway greenhouse effect occurred?



Replies:
I do not know where you read this information. With regard to C02 levels of recent years, they seem to increase steadily. Some say the greenhouse effect is happening right now, some say it is only appearing to happen because of the location of weather stations-. There have been many questions asked in this section with some very good answers for both sides. Rather than summarizing them here, why do not you look through the global warming questions and see if maybe your question has already been answered.
