Those 3% emissions of ours are now 30% of the CO2 in atmosphere.
We've increased the CO2 be almost 50% of what it was.
Because our emissions from burning CO2 that was stored deep underground aren't in balance with CO2 being naturally removed by the ecosystem.
You do understand what the word 'balance' means, right?
BTW, the CO2 that was naturally in the atmosphere does have a warming effect. It keeps the earth temperature at a level where we and most plants and animals can survive comfortably on most of the Earth's surface.
Because that's what we've all evolved to.
Without the natural CO2 keeping Earth warm, life on this planet would look very different.
Uh oh, evolution might be another scientific theory too scary for deniers.
