The correlation of carbon dioxide with temperature, of course, does not establish whether changes in atmospheric composition caused the warming and cooling trends or were caused by them.

当然，二氧化碳与温度的相关性并不能确定是大气成分的变化导致了气候变暖或变冷的趋势，还是它们本身造成的。

Astronomers would like to pin down the masses of the planets (information difficult to acquire with Kepler), as well as getting that data on atmospheric composition.

As an explanation for the conundrum of the ice ages, this notion could only hold water if a mechanism for such large changes in atmospheric composition might be found in the real world.

Each day, the scientific community collects millions of individual Earth observations, allowing us to examine, monitor, and model atmospheric composition, seismic activity, ecosystem health, weather patterns, and hundreds of other characteristics of our planet.
