The finite-temperature behavior of gluon and of Faddeev-Popov-ghostpropagators is investigated for pure SU(2) Yang-Mills theory in Landau gauge.We present nonperturbative results, obtained using lattice simulations andDyson-Schwinger equations. Possible limitations of these two approaches, suchas finite-volume effects and truncation artifacts, are extensively discussed.Both methods suggest a very different temperature dependence for the magneticsector when compared to the electric one. In particular, a clear thermodynamictransition seems to affect only the electric sector. These results imply inparticular the confinement of transverse gluons at all temperatures and theycan be understood inside the framework of the so-called Gribov-Zwanzigerscenario of confinement.Comment: 25 pages, 14 figures, 2 tables, minor changes of typographical and  design character, some minor errors corrected, version to appear in PR
