When looking at graphs showing 800,000 years of past climate data, there is a direct relationship over time between temperature and the concentration of carbon dioxide in the Earth's atmosphere is a true statement.

Explanation:

Many paleoclimate studies and research done by observing events like glacial cycles etc over the past 800,000 years about climate changes over the past years have proved the strong linear relationship between temperature and carbon dioxide concentration in the Earth’s atmosphere.

These studies clearly reiterate that when the carbon dioxide concentration in the atmosphere increases, the temperature also increases; and when the CO2 concentration decreases, the temperature also decreases. Carbon dioxide also controls the amount of greenhouse gases in the atmosphere by controlling the temperature.

Increased CO2 levels increases temperature which in turn will increase the evaporation of greenhouses gases present in the atmosphere including CO2 from the reservoir; however, the CO2 can stay in the atmosphere for very long time. All of these factors have led to various climate changes globally .
