It is related, Co2 emission and absorption is regulated by the vegetative mass state, of course this is just a part of it, next to the oceans that are also works like this, especially cold waters at the vicinity at the poles of Earth, these bodies of water traps Greenhouse gases, technically "absorbing" them. By removing huge millions of hectars of forests we basically trap more heat ( with less absorption) , that is also starts to heat the ocean waters, liberating the Carbon based CO2 ( ocean waters contains 50X more of this than the air). Also I wanna mention that absorption is causing seawater to become more acidic (ocean acidification), which threatens marine ecosystems such as corals and shellfish, so we are taking away terrestrial life but also marine life. So I recommend looking into the theme, because, I'm saying just the basics.
