China’s policy of planting trees is likely playing a significant role in tempering its climate impacts. An international team has identified two areas in the country where the scale of carbon dioxide absorption by new forests has been underestimated. Taken together, these areas account for a little over 35% of China’s entire land carbon “sink”, the group says.
Which of the following is the best title of the passage?

A．Greenhouse Gas Emission Largely Reduced

B．Roles of Carbon Sinks Proved by New Study

C．China’s Forest Carbon Absorption Underestimated

D．Climate Impacts Balanced Due to China’s Afforestation
