Finally life is good... until another chunk of stratosphere hits the dirt. (parentpreviews.com)
Previous research had shown that the loss of ozone molecules (which absorb solar energy) cools the lower stratosphere by six degrees Celsius each spring. (scientificamerican.com)
That leaves a gap as much as 5 km thick in the lower stratosphere where climate - cooling aerosols can persist, yet not show up, in satellite data. (sciencemag.org)
