全球气候变暖是由于大气中吸热气体浓度增加所引起的；
The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere;
全球变暖的原因是像二氧化碳这样的吸热气体，被滞留在大气层中，导致地球温度上升。
Global warming occurs when heat-trapping gases, such as carbon dioxide, get trapped in the atmosphere, causing the Earth's temperature to rise.
耕作还会将土壤中的二氧化碳释放到大气中，而免耕能够保持住土壤中的碳，并且避免机械设备释放吸热气体。
Tilling also releases carbon dioxide from the soil into the atmosphere. No-till keeps carbon in the soil and avoids the release of heat-trapping gases from motorized equipment.
报告认为相比于人工林原生成熟森林可以储存更多的二氧化碳，因此砍伐原生林的后果比砍伐次生林更严重，将会释出更多的吸热气体。
Established forests store much more carbon dioxide than plantations, so cutting them down releases more heat-trapping gases, it concluded.
韩国在2009年11月宣布第一个温室气体减排目标，承诺到2020年将从2005年水平减少4％的二氧化碳和其他吸热气体的排放量。
South Korea announced its first greenhouse gas reduction target in November 2009, pledging to cut emissions of carbon dioxide and other heat-trapping gases by 4% below 2005 levels by 2020.
