We compare the DAMA signal to the muon flux underground, which is annually modulated due to temperature variations in the stratosphere. We show that the muon flux at LNGS and the DAMA signal are tightly correlated. Different mechanisms were proposed in the literature by which muon-induced events may dominate the signal region in DAMA. We discuss simple statistical constraints on such mechanisms and show that the DAMA collaboration can falsify the muon hypothesis, if it is wrong, by reporting their annual baseline count rates.
