Pulling is easy, the "technology" is called trees and actual technology will never be able to compete with them as long as the CO2 content in the atmosphere is measured in hundreds of ppm (and if it ever reaches into the thousands we might just as well give up and focus on building mementos for passing alien civilizations to find) The challenge is to keep the extracted carbon from returning to the atmosphere. Those underground reservoirs of coal and hydrocarbons we have been digging up all the time are hard to beat.
