Since the re-election of the most recent Democratic Party corporate shill to the Presidency of the United States there has been the usual walk back of the promises to address Global Warming: we have to preserve Jobs (not incidentally, with them, corporate profits).
We need not lose hope, however reasonable it be not to place any in this President. Previous acts of international co-operation to cope with human-orinated threats to the planet have had a certain degree of success.
Gerardo Carbajal, head of the Department of Atmospheric Monitoring, of the Argentinian Meteorological Service, has reported that this year the ozone hole over the South Pole was one of the smallest ever (they open during the Southern Hemisphere’s summer) and one that closed up earlier than expected. Susana Diaz, the head of the Ozone Radiation Laboratory of the Southern Center for Scientific Research in Tierra del Fuego and a member of the Argentinian National Scientific Research Council, concurs that in recent years have seen a decrease in the ozone deficit within the hole.
Two years ago, in 2010, the United Nations Environment Program reported that the ozone hole had stopped growing. This was 25 years after the signing of the Vienna Convention for the Protection of the Ozone Layer mandated international termination of the production of chlorofluorocarbonates and 15 years after the three chemists who predicted the danger of chlorfluorocarbonates to the ozone layer won the Nobel Prize.
