In this paper, we estimate the conditions under which such tearing may give rise to full nonlinear magnetic reconnection in the turbulent eddies. When those conditions are met, a new turbulence regime is accessed where reconnection-driven energy dissipation becomes common, rather than the rare feature that it must be when they are not. We conclude that while such conditions are very stringent for fluid-scale eddies, they are easily met for kinetic-scale eddies; in particular, we suggest that our arguments may help explain recent Magnetospheric Multiscale (MMS) observations of (so-called) electron-only reconnection and of energy dissipation via electron Landau damping in the Earthʼs magnetosheath. <a href="http://library.psfc.mit.edu/catalog/reports/2020/20ja/20ja044/abstract.php">PSFC REPORT PSFC/JA-20-44</a><br /><br />N.F.L. was partially funded by NSF CAREER award no. 1654168 and by the NSF-DOE Partnership in Basic Plasma Science and Engineering, award no. de-sc0016215.
