According to foreign media reports, at present, the United Nations reports a new study shows that the ozone hole over Antarctica has stopped gradually become larger, the ozone hole is expected to ten years will begin to shrink.
Scientists say the gradual recovery of the ozone layer is due to a number of countries have decided to phase out the use of ozone-depleting chlorofluorocarbons artificial gas. The study is the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) who co-authored the study.
World Meteorological Organization Secretary-General Michael – Yarrow (Michel Jarraud) said: “The international joint action co-governance of the ozone layer, is a success story of environmental protection, which will encourage us to the same level of urgency and solidarity, and with the completion of a larger The challenge – to combat global climate change. “
Ken NASA – Jukes (Ken Jucks) Dr. said, humans began to change the atmosphere to gradually restore the atmosphere before the Industrial Revolution.
Scientists can not fully determine the ozone hole can be completely “self-healing”, the British Antarctic Expedition, David – Vaughan (David Vaughan) professor said, we need to be very careful to control the ozone hole, there are signs of ozone trends and gradual recovery. Antarctic survey data still need a few weeks to process is completed, we hope to confirm this finding, if it is accurate, will demonstrate the potential power of international agreements.
World Meteorological Organization, a senior scientist Gail – Blatten (Geir Braathen) pointed out that currently appear on the nineties of the ozone hole has stopped growing trend. Although the good news is that the ozone layer repair signs appear gradually, but the Earth’s atmosphere in greenhouse gas emissions must pay close attention this week, the World Meteorological Organization says the index hit a record high greenhouse gas, carbon dioxide emissions from human activities exacerbate global climate change.
