Tree Ring Data Underestimates Temperature Declines Due To Volcanos

You can use tree rings to estimate climate cooling due to volcanic erruptions. But, this method of estimating paleoclimate has limitations, especially in cases of rapid and severe volcanic erruption driven climate change, because all cooling below a given threshold is invisible since tree rings can get no smaller or aren't formed at all in a given year if it is too cold.
