美国一个联合研究团队认为,黑碳或烟灰对气候变暖具有较强的影响,其致暖效应大约是头号温室气体CO2的三分之二,跃居CH4之前,超出先前估计的两倍。该研究成果发表在最新一期的《地球物理学研究学报》上。黑碳是一种吸光性物质,可强烈吸收太阳短波辐射,同时释放红外辐射,加热周边大气。它在大气中留存时间为数日至几周,因而可产生区域增温效应。该研究认为,黑碳或烟灰对气
A joint research team in the United States believes that black carbon or soot has a strong effect on climate warming, with warming effect being about two-thirds of the number one greenhouse-gas CO2, ahead of CH4, more than double the previous estimate. The research results published in the latest issue of “Journal of Geophysical Research” on. Black carbon is a light absorbing material that strongly absorbs solar shortwave radiation while releasing infrared radiation that heats the surrounding atmosphere. It stays in the atmosphere for several days to several weeks, which can produce regional warming effect. The study concluded that black carbon or soot on the gas
