Question

Quizplus · Accepted Answer

CO₂ is a representation of CO2 (carbon dioxide) using chemical element symbols and atomic numbers. CO2 levels would take hundreds or thousands of years to return to nineteenth-century levels even with a 90% cut in emissions immediately due to its long atmospheric lifetime and the slow processes by which carbon is sequestered in the ocean and terrestrial ecosystems.
