The Earth has been warming or cooling since it was formed. I do not trust the data presented here (way too many people with an agenda collecting and manipulating data and way too short of a time frame using consistent measurement methods - satellites, ice cores, temperature stations, tree rings, etc.)
So, I suspect that the Earth is changing temperatures based on natural processes that have been happening for eons, but I cannot trust the people who are telling me they are certain that it is heating up and that we are responsible for it.
Of course we’re responsible, there’s none mightier than man. Human’s are the be-all end-all. Just look around- it should be obvious. Beauty and Perfection wherever you look.
