Stellar flares present challenges to the potential habitability ofterrestrial planets orbiting M dwarf stars through inducing changes in theatmospheric composition and irradiating the planet's surface in large amountsof ultraviolet light. To examine their impact, we have coupled a generalcirculation model with a photochemical kinetics scheme to examine the responseand changes of an Earth-like atmosphere to stellar flares and coronal massejections. We find that stellar flares increase the amount of ozone in theatmosphere by a factor of 20 compared to a quiescent star. We find that coronalmass ejections abiotically generate significant levels of potentialbio-signatures such as N$_2$O. The changes in atmospheric composition cause amoderate decrease in the amount of ultraviolet light that reaches the planetssurface, suggesting that while flares are potentially harmful to life, thechanges in the atmosphere due to a stellar flare act to reduce the impact ofthe next stellar flare.
