Climate change caused by anthropogenic CO2 emissions persists for over a thousand years and even short lived gases such as methane have long-term effects once they warm the deep ocean.
Carbon dioxide displays exceptional persistence that renders its warming nearly irreversible for more than 1,000 years..(edit).. dampening factors that slow temperature increase during periods of increasing concentration also slow the loss of energy from the Earth’s climate system if radiative forcing is reduced.
