New paper finds that a solar proton event could cause global cooling of more than 3C — Paper published today in Atmospheric Chemistry and Physics
Study 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, must be expected to have a major impact on atmospheric composition throughout the middle atmosphere, resulting in significant and persistent decrease in total ozone,' resulting in a 'significant [global] cooling of more than 3C'
