  Numerous laboratory measurements have provided a sound physical basis for the
cosmic-ray driven electron-induced reaction (CRE) mechanism of
halogen-containing molecules for the ozone hole. And observed spatial and time
correlations between polar ozone loss or stratospheric cooling and cosmic rays
have shown strong evidence of the CRE mechanism [Q.-B. Lu, Phys. Rep. 487,
141-167(2010)]. Chlorofluorocarbons (CFCs) were also long-known greenhouse
gases but were thought to play only a minor role in climate change. However,
recent observations have shown evidence of the saturation in greenhouse effect
of non-CFC gases. A new evaluation has shown that halocarbons alone (mainly
CFCs) could account for the rise of 0.5~0.6 deg C in global surface temperature
since 1950, leading to the striking conclusion that not CO2 but CFCs were the
major culprit for global warming in the late half of the 20th century [Q.-B.
Lu, J. Cosmology 8, 1846-1862(2010)]. Surprizingly, a recent paper [J.-W.
Grooss and R. Muller, Atmos. Environ. 45, 3508-3514(2011)] has criticized these
new findings by presenting "ACE-FTS satellite data". Here, I show that there
exist serious problems with such "ACE-FTS satellite data" because the satellite
has essentially not covered the Antarctic vortex in the presented months
(especially winter months during which most effective CRE reactions are
expected) and that the criticisms do not agree with the scientific facts in the
literature. Instead, real data from multiple satellites provide strong evidence
of the CRE mechanism. So far, the CRE mechanism is the only one that reproduces
and predicts 11-year cyclic variations of ozone loss in the Antarctic O3 hole
and of resultant stratospheric cooling, and the CFC mechanism can well explain
both recent global warming and cooling. These findings should improve our
understandings of the ozone hole and global climate change.
