Atmospheres are our main observation window into the physical and chemical properties of exoplanets. In recent years, observations at high spectral resolution have allowed several breakthroughs in terms of their composition, dynamics and climates. These results have revealed extreme phenomena such as high-speed winds, atmospheric escape or metallic rains, further stretching the amazing diversity of planets beyond our Solar System and establishing new promises for the characterisation of more Earth-like planets. I will review some of these recent results and discuss future prospects.
