平衡大气中的二氧化碳

Balancing Atmospheric Carbon Dioxide

二氧化碳浓度上升与全球温度变暖正在广泛引起人们的关注,有关大气层的国际法的压力正在迅速升级,然而,对温室效应的必然性、时间、范畴与原因等普遍存在的错误概念已阻碍了有效的舆论与行动。对南极冰核、美洲的雨林、加勒比珊瑚礁的观察表明。

Rising carbon dioxide and global temperatures are causing increasing worldwide concern, and pressure towards an international law of the atmosphere is rapidly escalating, yet widespread misconceptions about the greenhouse effect' s inevitability, time scale, and causes have inhibited effective consensus and action.Observations from Antarctic ice cores, Amazonian rain forests, and Caribbean coral reefs suggest that the biological effects of climate change may be more severe than climate models predict. Efforts to limit emissions from fossil-fuel combustion alone are incapable of stabilizing levels of carbon dioxide in the atmosphere. Stabilizing atmospheric carbon dioxide requires coupled measures to balance sources and sinks of the gas,and will only be viable with large-scale investments in increased sustainable productivity on degraded tropical soils, and in long-term research on renewable energy and biomass product development in the developing countries. A mechanism is outlined which directly links fossil- fuel combustion sources of carbon dioxide to removal via increasing biotic productivity and storage. A preliminary cost- benefit analysis suggests that such measures be very affordable, costing far less than inaction.
