I've posted graphs more than once that show universally accepted NOAA CO2 concentration levels increasing exponentially, as well as global troposphere temps (since 1979) increasing sharply as well. The potential effects are outlined in the UN article attached.
Given that the impacts will last for centuries, even if we achieved Net Zero tomorrow, it's imperative that we not waste time and do as much as possible...now...to staunch the increase.
