We have negotiated the Montreal Protocol, a treaty to protect the ozone layer, and strengthened it to the point where we have banned most of the major substances that create the ozone hole over Antarctica.
The ozone hole that forms each year in the stratosphere over Antarctica was slightly smaller in 2013 than average in recent decades, according to NASA satellite data.
Ozone levels at mid-latitudes reached their lowest recorded levels, while in the southern hemisphere winter of 1992, the ozone hole over Antarctica reached its largest ever size until then, with the fastest recorded ozone depletion rates.
Ozone levels at middle latitudes reached their lowest recorded levels, while in the southern hemisphere winter of 1992, the ozone hole over Antarctica reached its largest ever size until then, with the fastest recorded ozone depletion rates.
The ozone hole usually grows to a maximum size by early October. Subsequently, as the Antarctic vortex, which is closely linked to the growing and shrinking of the ozone hole, becomes weaker, the ozone hole gradually becomes smaller until it disappears in November through December.
The thick layers of Antarctic ice are imprinted with hundreds of millions of years of history, including changes in climate and the Earth's crust, This ice also continually affected by environmental changes like global warming and the ozone hole.
The author calls for cooperation among the Chinese government, individuals, and people from all over world in controlling the emission of greenhouse gases responsible for the ozone hole.
The topic vary from: clean water in Singapore, the indigenous people of the Philippines, the economic development in China and the ozone hole, and the bees and everyday lives in Japan.
The AuthaGraph World Map can be used as a map that centers on polar regions not only as a sea route chart but also for research into the ozone hole and for oil field development.
The same individuals who claim the science of global warming is"not settled" have also denied the truth about studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole.
An international treaty was established fairly quickly to deal with the ozone hole, but the main point shows how rapidly we can produce major changes to our atmosphere and how long it takes for nature to recover.”.
