CO2 is 40% now than it was pre-industrial times. That's a significant increase.

As to your number 3, you merely point to things which coincide. Since temperatures go up and down all the time, and rarely stay flat, it's no surprise that it's risen. It was a choice of two. Not a HUGE coincidence, by any measure.
It is expected that if CO2 goes up temperature happens. That is a prediction of global warming. One which the correlation confirms.

Who are "they all"?
In the thirty years leading up to the 1970s, available temperature recordings suggested that there was a cooling trend. As a result some scientists suggested that the current inter-glacial period could rapidly draw to a close, which might result in the Earth plunging into a new ice age over the next few centuries. This idea could have been reinforced by the knowledge that the smog that climatologists call ‘aerosols’ – emitted by human activities into the atmosphere – also caused cooling. In fact, as temperature recording has improved in coverage, it’s become apparent that the cooling trend was most pronounced in northern land areas and that global temperature trends were in fact relatively steady during the period prior to 1970.
At the same time as some scientists were suggesting we might be facing another ice age, a greater number published contradicting studies. Their papers showed that the growing amount of greenhouse gasses that humans were putting into the atmosphere would cause much greater warming – warming that would exert a much greater influence on global temperature than any possible natural or human-caused cooling effects.
Is that all you've got? Already long debunked nonsense from the Heartland institute? The very group I've pointed out have been lying to you?
Come back with some valid evidence which debunks global warming from a reputable group and then maybe I'll listen to you.
