Congratulations, that's called science. I don't get where so many people forgot the point of science. Create a falsifiable hypothesis, test said hypothesis over and over again with new techniques and data. When said hypothesis is invalidated, create new hypothesis. Our techniques and data collection and quality are orders of magnitude better today.
A problem is that public figures don't make a difference between scientific theories based on how likely they are to be valid. They just take some theory, say it is "science" and then go on with "science is on my side!". This abuse of science is why we have so many science denialists today. And not just on the right side, so many on the left denies things like biological factors of IQ.

All the data points to anthropogenic global warming and the fundamental phenomena has been understood for well over a century.
