Seeing as how industrialization in it's entirety has failed to have been shown to appreciably affect global temperature changes...
I don't see the failure. CO2 levels are directly connected to temperature changes. So if we find the cause for the changing CO2 levels, we have the cause for the temperature changes. And CO2 levels have changed in the last 100 years. Just go to a library and take a 100 year old book about the atmosphere, and you will find that there are measurements of about 270 ppm CO2. Then take a measurement yourself, and you will get about 400 ppm CO2 today. So we have a 130 ppm increase of CO2 levels within 120 years. Now you could go and calculate how many tons of CO2 130 ppm represent.
Lets do some back-of-the-envelope calculations:
See, how our estimation of carbon usage and increased CO2 fit nicely? And we know that CO2 levels and Earth surface temperatures are closely correlated. So we have a direct correlation between industrialization and temperature increase.
I know that many people don't like xkcd, but he had a nice cartoon where you can see the difference between a natural changing climate and what we have right now: Timeline
