Adding Deaths (IMAGE) Columbia Climate School Caption The addition of 4,434 metric tons of carbon dioxide emissions beyond the baseline 2020 rate is expected to cause one human death by 2100. Here, lower bars indicate individuals in each country would have higher impact; those 4,434 tons are equivalent to the lifetime emissions of just 3.5 Americans, as opposed to 15.6 Mexicans or 146.2 Nigerians.
