Using an advanced model of the Earth's atmosphere, atmospheric physicist Paul Newman of NASA's Goddard Center and colleagues have been playing a game of climatic «what if» by charting the evolution of
ozone in the upper atmosphere in two different scenarios.
Ground - level ozone, which is distinct from
the ozone in the upper atmosphere that protects the planet from ultraviolet radiation, is harmful to human health, exacerbating asthma attacks and causing difficulty breathing.
Something was destroying
the ozone in the upper atmosphere.
I actually don't consider
the ozone in the upper atmosphere to be relevant to temperatures or ice extent.
