Human interventions in the carbon cycle designed to influence carbon transfers and mitigate impacts of climate change
Humans deliberately alter the carbon cycle to slow climate change. They do this by capturing carbon, restoring forests, or storing carbon underground.
Real World
Iceland's CarbFix project at the Hellisheiði geothermal plant dissolves captured CO₂ in water and injects it into basalt rock, where it mineralises into solid carbonate within two years — permanently locking away over 12,000 tonnes of CO₂ annually.
Exam Focus
Evaluate means weigh up pros and cons — always discuss limitations such as cost, scale, or time lag alongside benefits.
