So this diagram illustrates a computer simulation that has looked at all the different factors that we know can influence the Earth's climate, so sulfate particles from air pollution, volcanic dust from volcanic eruptions, changes in solar radiation, and, of course, greenhouse gases.
这张图展示了计算机模拟， 考虑了各种 可能影响地球气候的因素， 从空气污染中的硫酸盐颗粒， 到火山喷发中的火山灰， 到太阳辐射的改变， 当然，还有温室气体。
