A media personality argues that global temperatures are not rising, because every year an increase is reported, such as .09 degrees C. The difference from the previous year is less than the margin of error of about .13 degree C, so that difference should be ignored. What is a strong counter argument?

Question

A media personality argues that global temperatures are not rising, because every year an increase is reported, such as .09 degrees C. The difference from the previous year is less than the margin of error of about .13 degree C, so that difference should be ignored. What is a strong counter argument? 

 

1. The difference is only .4 but that is still a significant change.

2. The margin of error is quite small compared to the change year over year, so it is a significant issue.

3. The change of .9 is not a lot and thus should be ignored.

4. The margin of error is larger than the increase so we should consider it an issue just extra information and thus can be ignored.
