I read to my son each night before he goes to sleep. Last month we were working our way through Enid Blytons' Famous Five books. At the moment we are reading Popular Science FYI. The book consists of - '229 curious questions answered by the world's smartest people'. (Note how these super smart people got the possessive s punctuation wrong! It should be worlds')
One question tonight was "does smoking contribute to global warming". The answer was no, and it may even help to reduce global warming a little! The theory was, that the smoke particles from the cigarette, and the smoker, will reflect some of the energy from the sun and so that energy will not contribute to warming the surface of the earth.
This positive was balanced in the next question/answer where they pointed out that 4,500,000,000,000 (4.5 trillion), cigarette butts are thrown away each year. They take many years to degrade and each one puts 600 different chemicals into the soil!
