Abstract: Cosmic Rays affect the climate though changes in the atmospheric ionization. This emerging theory is supported by evidence which has been accumulating over the past decade or so. We will review this evidence, ranging from climate variations associated with cosmic ray flux variations over multi-million year time scale (and which are the result of the changing environment around the solar system), to experimental results. We will then talk about the implications of this link, to our understanding of climate change on a wide range of time scales, including the 20th century global warming.
