众所周知,矿物燃料燃烧使大气中的二氧化碳(CO_2)不断增加,引起增温效应,致使地球增温,极地冰川融化,海面上升。那么,CO_2含量增加率究竟为多少呢?由此而产生的增温效应又为多大呢?关于这方面的评论和估价众说不一。但最近由于测定和模拟计算精确度的提高,正渐趋统一。 据1958年以来夏威夷马乌纳罗的观测结果表明,大气中CO_2含量1981年已超过340ppm,增加率为2.40％,相当于每年增加1.3ppm。据R.M.Rotty计算表明,目前每
It is well-known that the combustion of fossil fuels increases the atmospheric carbon dioxide (CO 2), causing the warming effect, resulting in the warming of the Earth, the melting of polar glaciers and the rising sea level. So, what is the increase rate of CO 2 content? What is the warming effect caused by this? What are the different comments and valuations? However, the accuracy of measurement and simulation has recently become more and more unified. Observations from Mauna Lo in Hawaii since 1958 show that atmospheric CO 2 levels exceeded 340 ppm in 1981, an increase of 2.40%, equivalent to an annual increase of 1.3 ppm. According to R.M. Rotty calculations show that currently every
