The most fundamental modes of variability of the global climate system are the diurnal and seasonal cycles, Which are associated with large and well-defined variations in the solar forcing.

在全球气候系统中，由于太阳的强迫作用，最基本的变化模式是日变化和季节变化。

This allows more solar radiation to penetrate the earth's atmosphere, which promotes a climate forcing effect (more short wave radiation reaches the earth, warming land and sea-surface temps).

这使得更多的太阳辐射穿透地球的大气层，从而促进气候强迫作用(更短波辐射到达地球，升高陆地和海洋表面气温)。

We can directly measure the results that solar forcing had, such as in driving CO2 out of the oceans by heating them up, and the resultant increase in temperature that this increase caused.

But the main external candidate is solar, and more work is required to improve the "paleo" solar forcing record and to understand how the climate system responds both globally and regionally to solar forcing.

Perhaps most importantly, intense pressure from heavily subsidized Chinese manufacturers is driving a surprisingly competitive solar market, forcing Solyndra to get costs down faster than the start-up firm could achieve.
