The Earth goes through cycles of cooling and warming due to natural increases and decreases in Co2e concentration. The magnitude of which is much smaller than the current level of temperature change, much less predicted future temperature change.

You can obviously notice two things.
1.) The current level of global warming is unprecedented in scale, since 650k years ago.
2.) There is undeniable correlation between CO2 concentration and temperature. We have a perfectly reasonable, testable model as to why this correlation takes the form of CO2 -> temperature rise.
I am honestly staggered to meet people that are actively trying to delude themselves as such. I would be really interested in finding out the real reason you can't consciously accept it. I am curious. The overwhelming majority of scientists make one claim, and yet you do not believe them? It is their job, to know what they are talking about. Why do you trust your gut instinct over people who have spend collectively millions of man hours researching this topic?
Oh and as for the 'What can a man who hopes to become the most powerful man in the world do to stop climate change?" The answer is, a lot. We could sort this out if it weren't for people like you.
