由土地利用、土地利用变化和林业(LULUCF)活动产生的生态系统的固碳作用，是降低大气中温室气体浓度增加速度的重要途径之一。
Enhancing carbon sequestration in land use, land-use change and forestry (LULUCF) is one of the most important means to reduce the growth rate of greenhouse gas concentrations in the atmosphere.
随着人类活动增加，温室气体在大气层中的浓度超过了自然状态，过多热量被保存。
As human activity increases the concentration of these gases in the atmosphere far beyond their natural levels, much more heat is trapped.
导致这一现象的原因可能就是大气层中温室气体浓度增加引起的气候变化，目前大气层中的温室气体浓度已经从1700年的280ppm增加到现在的390ppm (ppm意为百万分之一，大概是指体积的比)。
The reason may well be climate change caused by increasing concentrations of atmospheric greenhouse gases-now roughly 390 parts per million, up from 280 PPM in the 1700s.
甲烷作为重要的温室气体，它在大气中的浓度正在增加。
Methane as an important green house gas, its concentration in the global troposphere is increasing.
由于大气层中温室气体浓度的增加，地球正在变暖。华盛顿一个多雪的冬天并不能改变这个事实。
The planet is warming due to increased concentrations of heat-trapping gases in our atmosphere. A snowy winter in Washington does not alter this fact.
人类活动造成大气中温室气体浓度急剧增加已成为全球变化中最主要和最直接的变化。
Human activities has result in the increase of atmospheric concentration of greenhouse gases, which is concerned as a main cause of the global climate change.
一些科学家把这归结于大气中温室气体的浓度增加。
Some attribute this to an increased concentration of greenhouse gases in the atmosphere.
工业、交通和能源消耗等人类活动对大气中温室气体的浓度增加起着极其重要的作用。
Human activities such as industry, transportation and energy consumption, have great impact on the gas concentration of the atmospheric greenhouse.
气候变暖的原因主要是工农业生产中产生二氧化碳、甲烷等温室气体导致大气中这些气体浓度的增加。
The main reason for it is that such glasshouse gases as CO2, CH4 and so on in the atmosphere have become denser than ever because of industrial and agricultural production.
气候变暖的原因主要是工农业生产中产生二氧化碳、甲烷等温室气体导致大气中这些气体浓度的增加。
The main reason for it is that such glasshouse gases as CO2, CH4 and so on in the atmosphere have become denser than ever because of industrial and agricultural production.
