“We are evaporating our coal mines into the air” Although the statement was effective in grabbing attention in 1898, what process were they really referring to in discussing the amount of CO2 being added to the air?

In other words, no text-like shorthand or abbreviations allowed. This is college-level work in a discussion format. A clean-burning automobile engine emits about 5 lb of C atoms in the form of CO2 molecules for every gallon of gasoline it consumes. The average American car is driven about 12,000 miles per year. Using this information, check the statement that the average American car releases its own weight in carbon into the atmosphere each year. List the assumptions you make to solve this problem. Hint: You need a couple of equalities: 12000 miles ＝ 1 yr, look up # gallons ＝ miles for the average car, 5 lb carbon ＝ 1 gallon gas. With this information, you can use conversions to determine how many lb of carbon the car gives off per year to go 12000 miles and compare to the average weight of a car. Writing in the London, Edinburgh, and Dublin Philosophical Magazine Arrhenius described the phenomenon: “We are evaporating our coal mines into the air” Although the statement was effective in grabbing attention in 1898, what process were they really referring to in discussing the amount of CO2 being added to the air? Hint…think about all the forest fires. C + O2 LaTeX: longrightarrow⟶ CO2 The Mauna Loa Hawaii atmospheric CO2 concentration measurements taken since 1958 constitute the longest, continuous record of atmospheric CO2 available in the world. https://www.esrl.noaa.gov/gmd/obop/mlo/programs/coop/scripps/co2/co2.html (Links to an external site.) Are there other reasons why the concentration of CO2 has changed?
