Removing carbon from Earth's atmosphere may not reverse devastating changes to weather patterns in vulnerable areas, a new study suggests.
In the study, Korean researchers simulated how removing large quantities of the greenhouse gas carbon dioxide from the air might affect the progress of local climate changes related to global warming. The study, based on computer modeling, examined a hypothetical scenario, in which carbon dioxide concentrations continued to rise from present-day levels for 140 years, then were gradually reduced back to the initial levels over another 140-year period.
