Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

But because they’re potent greenhouse gases, they still affect the climate. Combined, their emissions are equal to the CO 2 emissions in 2020 for a smaller developed country like Switzerland. —Dr Western Resources Western, L.M., CFCs are chemicals known to destroy Earth’s protective ozone layer.

MUCHACHAS study finds aging of organic aerosols is caused by OH radicals; climate models need to be updated

Green Car Congress

An international team of researchers has discovered that chemical aging determines to a major extent the concentration and the characteristics of organic aerosol particles, which have a significant effect on climate. To date, this aspect has not been accounted for in regional and global climate models. Donahue et al., 1115186109.
