1000 years of changes in carbon emissions1000 Years of Changes in Carbon Emissions, CO2 Concentrations and Temperature: This 1000-year record tracks the rise in carbon emissions due to human activities (fossil fuel burning and land clearing) and the subsequent increase in atmospheric carbon dioxide concentrations, and air temperatures. The earlier parts of this Northern Hemisphere temperature reconstruction are derived from historical data, tree rings, and corals, while the later parts were directly measured. Measurements of carbon dioxide (CO2) in air bubbles trapped in ice cores form the earlier part of the CO2 record; direct atmospheric measurements of CO2 concentration began in 1957.
