Carbon dioxide is simply a natural chemical that occurs everywhere. Rocks with carbon components slowly react with oxygen in the air to form carbon dioxide. Combustion always produces carbon dioxide. Many things produce it.

CO2 emission from the burning of fossil fuels is a issue, yet no longer as enormous as some 'greenies' might have you ever have self belief. FYI i'm a scientist that works for the DOE and that i've got no longer any vested hobby in any form of power technology. the quantity of carbon it is sequestered underground and interior the ambience is in an equilibrium by way of competing organic techniques. Digging it up and burning it disrupts that equilibrium. inspite of the shown fact that, the quantities in contact interior the organic techniques are bigger by using an order of value than the anthropogenic components. nonetheless, the equilibrium is disrupted adequate to have very substantive outcomes. that's kinda like including and bigger 2 hundred energy to a 2000 calorie food regimen without changing your interest point. you will detect a sparkling equilibrium weight, only by way of fact the planet will detect a sparkling equilibrium temperature, ocean acidity, and climate development. regrettably, which will displace human beings, tension some species to extinction, and alter climate types. New species will evolve, nonetheless, and factors that are desolate now gets greener. So... automobiles upload to atmospheric CO2 by using putting the carbon from fossil gasoline into the air. counting on your perspectives on our environment, it particularly is the two something particularly undesirable or only one thing we ought to manage. Regardless, reducing CO2 emissions will postpone the matters linked with climate substitute. figuring out regardless of if that's very well worth the important strikes that should leave human beings hungry and undesirable with a view to slow the technique is above my pay grade.

Anytime you burn a fuel with carbon in it, you will make carbon dioxide. Check your chemistry book.

Also decaying organic matter, like dead and rotting animals and plants give off low levels of carbon dioxide on their own.
