Abstract : We present the first study of the energy dependence of p$_t$ angular correlations inferred from event-wise mean transverse momentum (p$_$t) fluctuations in heavy ion collisions. We compare our large-acceptance measurements at CM energies $\sqrt{^{s}NN}$=19.6, 62.4, 130 and 200 GeV to SPS measurements at 12.3 and 17.3 GeV. p$_t$ angular correlation structure suggests that the principal source of pt correlations and fluctuations is minijets (minimum-bias parton fragments). We observe a dramatic increase in correlations and fluctuations from SPS to RHIC energies, increasing linearly with ln$\sqrt{^s}NN}$ from the onset of observable jet-related p$_t$ fluctuations near 10 GeV.
