Abstract
An analysis of the energy spectra of cosmic rays and particularly the precise data from the AMS-02 experiment support the view about the important role of the Local Bubble in the nearby interstellar medium. It is suggested that the bulk of CR below about 200Â GV of rigidity (momentum/charge ratio) comes from the modest number of supernova remnants in the Local Bubble which appear to have occurred some 106Â years ago and contributed to its formation. At higher rigidities the contribution from a 'Local Source', a single supernova remnant generated some 105Â years ago seems to dominate up to, at least 1000Â GV.
