Carbon dioxide in Earth's atmosphere - Wikipedia

Over the last 400,000 years the natural upper limit of atmospheric CO2 concentrations is assumed from the ice core data to be about 300 ppm. Other studies using proxy such as plant stomata, however, indicate this may closer to the average value, at least over the last 15,000 years. Today, CO2 concentrations worldwide average about 380 ppm.

CO2 vs Temperature: Last 400,000 years

Carbon dioxide (chemical formula CO 2) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide consists of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.The current concentration is about 0.04% (410 ppm) by volume, having risen from pre-industrial levels of 280 ppm.

CO2 Concentration Is Higher Than Ever in Human History

Jun 04, 2013· The theory that carbon dioxide concentration is related to the temperature of the earth’s surface is therefore wrong. The growth of plants in the Carboniferous caused a reduction in atmospheric oxygen and carbon dioxide, forming the basis for large deposits of dead plants and other organisms.

Over the Earth's history, there are times where atmospheric CO2 is higher than current levels. Intriguingly, the planet experienced widespread regions of glaciation during some of those periods. Does this contradict the warming effect of CO2? No, for one simple reason. CO2 is not the only driver of climate. To understand past climate, we need ...
