Carbon Dioxide is a Major Contributor
Climate change is partially man-made, in that we contributed to it with harsh chemicals and improper disposal. However, some other natural weather patterns occur every 100,000 years and every 11,000 years. For instance, Earth has experienced warm, or “interglacial” periods and cold periods, also called “ice ages” every 100,000 years or so, for at least 1 million years. Scientists have learned through their research that carbon dioxide is a major contributor to previous ice ages, and it’s influenced the Earth’s extreme temperature changes.
