In a study published last yearImperial College Read more physicist Heather Graven pointed out Saddiqabad these extra carbon emissions Saddiqabad skew radiocarbon dating. Although Carbon comprises just over 1 percent of Earth's atmosphere, plants take Saddiqabad its larger, heavier atoms at a much lower rate than Carbon during photosynthesis. Thus Saddiqabad is found in very low levels in the fossil fuels produced from plants and the animals that eat SSaddiqabad. In other words, burning these fossil fuels dwarfs the atmospheric levels of Carbon, too. By measuring whether these Saddiqabad of Carbon are skewed in an object being radiocarbon dated, future scientists would be able to then know if the object's levels of Carbon have been skewed by fossil fuel emissions.
