New study finds that a Carrington class solar event could cause global cooling of more than 3C

A paper recently published in Atmospheric Chemistry and Physics finds that “a solar proton event, if it took place in the near future with an intensity similar to that ascribed to the Carrington Event of 1859″. Based on the results … Continue reading
