====== Ozone depletion anomaly ======

According to a 2007 research project, the current atmospheric theories regarding depletion of the Earth's ozone 'layer' at the poles only account for around 40% of the actual depletion as measured by NASA.  See: [[http://www.iup.uni-bremen.de/sciamachy/sparc/downloads/rexnatlsparc2007.pdf|Is a major fraction of polar ozone loss due to a currently unknown mechanism ?]] (Alfred Wegener Institute for Polar and Marine Research, Potsdam, Germany)

An article covering the anomaly was published in //Nature//: [[http://www.nature.com/news/2007/070924/full/449382a.html|Chemists poke holes in ozone theory]], issue 449, 382-383.

The research results were not universally accepted by climate scientists.

There were also reports of large-scale emissions of 'banned' ozone-destroying gases used for refrigeration and air-conditioning etc., which go undeclared and may have been overlooked.
