A quick fact from Wikipedia: human activities such as the combustion of fossil fuels and deforestation have caused the atmospheric concentration of carbon dioxide to increase by about 35% since the beginning of the age of industrialization.
35% is a huge increase when you’re talking about the entire atmosphere of the planet.
Well can’t get much more unvauge than that. Buck would you consider a 35% increase in CO2 in our atmosphere “A lot”?
