Vedclass · Answer

(D) The carbon cycle is currently being significantly disrupted by human activities. $1$. The burning of fossil fuels (coal,petroleum,and natural gas) releases carbon that was locked away for millions of years back into the atmosphere at an alarming rate. $2$. This release contributes directly to the increase in greenhouse gases,such as $CO_2$,which trap heat in the atmosphere. $3$. Scientific data indicates that the concentration of atmospheric carbon has increased significantly (approximately $12-14\%$ or more in recent decades),leading to global warming and climate change. Therefore,all these factors are of immediate concern.
