**Data Collection and Conclusions**

Basic Example

The global temperature anomaly indicates how much warmer or colder the average global temperature is than normal during a particular time. A researcher conducting an observational study charted and analyzed atmospheric carbon dioxide (CO_{2}) levels and the global temperature anomaly in degree celsius since the year 1960.

The researcher observed that the rate of increase of atmospheric CO_{2} since 1960 (approximately 4.0% per decade). Based on this data, which conclusion is valid?
