"Heretic!"
Nothing humans do contributes significantly to climate change. Climate change is the result of natural forces of Sun, Earth and their interaction over hundreds of thousands of years. We are just damned lucky to be in an era of warming (if we still are) because if things were growing colder each day there would be murderous chaos in competition for declining food resources.
Mankind always flourished and made progress during warm periods, known as climate optimums.
Longer growing seasons mean more food and lower heating costs mean more expendable income for luxuries.
