crazy stuffAtmospheric CO2 is accurately and reliably documented. Human caused CO2 generation is a FACT as the isotopes of carbon are unique to human activity. So we know for a FACT that humans burning fossil fuels are increasing global greenhouse gasses. The greenhouse effect has been known and understood for a hundred years. Sea level rise, ocean acidification, glacial retreats, polar melting etc are clearly demonstrated and all are accelerating. Average global temperatures do not rely on thermometers on the tarmac at airports. We have sattelites, ocean bouys and far more reliable and sophisticated methods
In the past temperatures could well have risen first followed by an increase in CO2 as permafrost melted, wildfires increased etc....But it also works the other way around. Increased greenhouse gasses cause warming. Humans were not a factor in climate history....they are now and that's what matters
