温室气体传感器促进全球气候研究

　　不管什么怀疑论者可能会说，科学界接受的事实，我们的气候正在改变。衡量和量化这种变化将需要精确监测的基本指标和生命体征，为我们提供准确的数据来预测什么来。

　　本文着眼于传感器技术，可以和将用于测量和报告的微妙（而不是那么微妙）气候变化发生。这包括系统实时测量条件以及设计跟踪缓慢移动的指标预示着长期的趋势。所有的技术，配件，和发展系统的引用可以在Digi-Key网站找到的

　　CO2 analysis

　　The correlation between heat-trapping CO2 levels in the atmosphere and average global temperature has been well documented. Ice core samples going back 800，000 years have allowed researchers to measure the relative amounts of CO2 dissolved in the ice when it froze to indicate the how much of the gas was in the atmosphere at the time. Scientists point out that， like the rings of a tree， the thickness of the layered ice and relative amount of CO2 measured can be used to determine average temperature （there is， however， a time lag between changes in CO2 levels and changes in temperature）。

　　While historic geological data （Figure 1） shows anomalous periods with relatively high levels of CO2 while temperatures were statistically lower than expected， it is known that orbital patterns， sunspot cycles， relative glacier surface areas， volcanic activities， and other negative feedback factors have influenced this data.1
