"Climate change has more to do with the sudden and drastic climatic changes that have occurred abruptly over the last 100 years"
Also known as the only 100 year span we recorded this amount of information.
The climate has more to do with the Earth's distance from the sun, the tilt on the axis and surface sun activity than what man is or isn't doing. When all that happened were campfires from the few million people on earth, the climate still changed and we have no idea the year to year variance only long-term generalizations. The earth has been significantly warmer and colder than it currently is and life still survived and thrived. The alarmism associated with the changing climate is more of an issue than any affects man may have in my opinion.
