We explored how DM can interpret the excesses in e ± cosmic rays measured by FERMI, PAMELA and HESS. The results of the HESS and FERMI **data** indicate two specific things for any DM interpretation. First, the spectrum becomes steeper at around 1 TeV implying the scale of DM needs to be around a TeV. Second, the FERMI **data** is smooth from 100 GeV to around a TeV implying that a light DM explanation of PAMELA is inconsistent with the FERMI data.
