Over time it has become apparent that the increase in the CO2 concentration of the atmosphere, induced by anthropogenic activities, was and is continuing to provoke global warming, sea-level rise, ocean acidification and potentially global health issues (see Section 3). Concerns over these and other consequences of anthropogenic carbon emissions have led many to call for a global effort to attenuate or even reverse the trend of concentration change of CO2 in our atmosphere. Decreasing the rate of increase of atmospheric CO2 concentration can be attained either by 1) replacing carbon-emitting processes such as fossil fuel burning,...

4. 碳捕集与封存（CCS）

随着时间的推移，人类活动引起的大气二氧化碳浓度的增加已经变得越来越明显，并且正在继续引发全球变暖、海平面上升、海洋酸化和潜在的全球健康问题（见第 3 节）。对人为碳排放的这些和其他后果的担忧导致许多人呼吁全球努力减弱甚至扭转大气中二氧化碳浓度变化的趋势。降低大气二氧化碳浓度的增长率可以通过以下任一方式实现：1) 取代碳排放过程，例如化石燃料燃烧、……
