A Guide to Understanding Global Temperature Data

July 15, 2016

It is diffcult if not impossible to accurately adjust global temperature data from various sources.

Whether we use thermometers, weather balloons, or Earth-orbiting satellites, the measurements must be adjusted for known sources of error. Adjustments to global temperature data from various sources are diffcult if not impossible to do accurately and in an ubiased fashion, thus it is not surprising different scientists come up with different global warming trends—or no warming trend at all. Increasingly, the “science” of global warming is being based upon theories of what might happen, not on what is being observed to happen. And the observations are increasingly at odds with the theory.
