Actually that is not proof of anything other than the fact that CO2 levels are rising. Just like they did in the past. As there have been times in our history where there have been higher CO2 levels than currently exist with cooler temperatures. All this shows that in the last 800,000 years the CO2 levels have fluctuated between 180 to 300 ppm, Ice ages have come and gone, the ocean has risen and fallen over 300 feet and not a single human being had anything to do with that.

When you have politician and celebrities all chanting the same dire predictions of of which none have even come close to true. Then hopping on their private jets to accept environmental awards I wouldn't put too much stock it what they have to say. It would almost be like a televangelist getting caught with a hooker except the left doesn't seem to care about it.
