研究:太阳活动频繁让地球变冷

　　An increase in solar activity from the Sun actually cools the Earth, suggests a new research that will renew the debate over the science behind climate change. The research overturns traditional assumptions about the relationship between the Sun and global warming.

　　新研究表明，太阳活动趋于频繁事实上让地球变冷。这一研究将使关于气候变化背后科学原理的辩论重新开始。这项研究颠覆了关于太阳与全球变暖之间关系的传统假设。

　　The findings focused on a three-year snapshot of time between 2004 and 2007. As solar activity waned at the end of one of the Sun's 11-year cycles, the new data shows the amount of light and heat reaching the Earth rose rather than fell. Scientists also believe it may also be possible that during the next upturn of the cycle, when solar activity increases, there might be a cooling effect at the Earth's surface.

　　这项研究的时间范围是2004年到2007年。太阳活动的周期是11年。新数据表明，在一个周期末期太阳活动趋弱时，抵达地球的光与热的量增加而不是减少了。科学家们相信，在周期的下一个上升期，也就是在太阳活动趋于频繁时，可能会对地球表面产生冷却效应。

　　Over the past century, overall solar activity has been increasing and should therefore cool the Earth, yet global temperatures have increased.

　　在过去100年中，就总体而言，太阳活动是在增强，因此，原本应该让地球变冷，然而，全球气温却升高了。
