In short, no, not every scientist believes people create global warming. Although more and more scientists are becoming convinced that we are seeing a significant change in our climate, there are those who argue that it has more to do with solar cycles. Some meteorologists have also noted that, historically, climate warming has preceded increases in carbon dioxide levels, not the other way around. This is because when the Earth warms up, it also warms the oceans, which hold much of the world’s carbon dioxide in the form of carbonic acid. When the oceans get warm enough, the carbon dioxide is then released into the atmosphere.
