OZONE HOLE IN ANTARCTIC
·
According
to a recent study, published in Nature Communications, stated that the
Antarctic Ozone Hole has been massive in the last four years.
What are
the Key Highlights of the Study?
Ozone
Depletion:
·
The
Antarctic ozone hole has been consistently large and has shown thinning over
recent years, contrary to the expected recovery trend observed since the 2000s.
·
The
concentration of ozone at the center of the hole has notably reduced,
indicating significant thinning of the ozone layer.
·
The
concentration of ozone at the core of the ozone hole has decreased by 26% from
2004 to 2022, despite the efforts outlined in the Montreal Protocol, which
aimed to reduce human-generated chemicals that deplete the ozone layer.
Polar
Vortex Influence:
·
The
Antarctic ozone hole exists within the polar vortex, a circular wind pattern in
the stratosphere that forms during winter and is maintained until late spring.
·
Within
this vortex, the Antarctic air from the mesosphere (the atmospheric layer above
the stratosphere) falls into the stratosphere. This intrusion of air brings
natural chemicals (nitrogen dioxide, for example) which impact ozone chemistry
in October.
Factors
Affecting Ozone Depletion:
·
The
role of meteorological conditions, such as temperature, wind patterns, aerosols
from wildfires and volcanic eruptions, and changes in the solar cycle,
influenced the size and behavior of the Antarctic ozone hole.
Recommendations:
·
There's
a need for further research to understand the descent of air from the
mesosphere and its specific impacts on ozone chemistry.
·
Investigating
these mechanisms will likely shed light on the future behavior of the Antarctic
ozone hole.
What is
an Ozone Hole?
About:
·
An
Ozone Hole refers to a severe depletion of the ozone layer—a region in the
Earth's stratosphere containing a higher concentration of ozone molecules.
·
Ozone
molecules (O3) in this layer play a crucial role in shielding the Earth from
harmful Ultraviolet (UV) radiation from the sun.
·
The
ozone layer depletion leads to the formation of an area with significantly
reduced ozone concentrations, often observed over Antarctica.
·
This
phenomenon occurs primarily during the Southern Hemisphere's spring months
(August to October), though it can also be influenced by global factors.
Reasons
for Ozone Hole:
·
The
depletion is caused by human-generated chemicals known as ozone-depleting
substances (ODS), including Chlorofluorocarbons (CFCs), halons, carbon
tetrachloride, and methyl chloroform.
·
These
substances, once released into the atmosphere, rise to the stratosphere, where
they break down due to the sun's ultraviolet radiation, releasing chlorine and
bromine atoms that destroy ozone molecules.
·
The
Antarctic ozone hole is the most famous and severe example of this phenomenon.
It's characterized by a drastic reduction in ozone levels, allowing increased
amounts of harmful UV radiation to reach the Earth's surface.
Impact:
·
The
increased UV radiation poses health risks to humans, including higher rates of
skin cancers, cataracts, and compromised immune systems.
·
UV
radiation can harm various organisms and ecosystems. Ozone depletion can
indirectly influence climate change. Changes in the stratosphere due to ozone
depletion can impact atmospheric circulation patterns, potentially affecting
weather and climate in certain regions.
What are
the Global Initiatives to Curb Ozone Depletion?
·
The
1985 Vienna Convention for the Protection of the Ozone Layer was an
international agreement in which United Nations members recognized the
fundamental importance of preventing damage to the stratospheric ozone layer.
·
The
1987 Montreal Protocol on Substances that deplete the Ozone Layer and its
succeeding amendments were subsequently negotiated to control the consumption
and production of anthropogenic (ODSs) and some hydrofluorocarbons (HFCs).
·
The
Protocol was signed by 197 parties in 1987 to control the use of ozonedepleting
substances, mainly chlorofluorocarbons (CFCs). Montreal Protocol deals with the
development of replacement of substances, firstly hydrochlorofluorocarbons
(HCFCs) and then HFCs, in a number of industrial sectors.
·
While
HFCs have only a minor effect on stratospheric ozone, some HFCs are powerful
greenhouse gases (GHGs).
·
The
adoption of the 2016 Kigali Amendment to the Montreal Protocol will phase down
the production and consumption of some HFCs and avoid much of the projected
global increase and associated climate change.
INTERNATIONAL TROPICAL TIMBER COUNCIL
·
The
59th meeting of the International Tropical Timber Council (ITTC), the administering
body of the Worldwide Tropical Wood Association (ITTO), as of late closed with
huge choices forming the eventual fate of feasible tropical backwoods the board
and the exchange of economically delivered tropical wood.
What are the Critical Results of the
59th meeting of the ITTC?
·
The
nations consented to underwrite eight tasks connected with maintainable
backwoods the board and related targets.
·
The
meeting likewise endorsed and embraced a spending plan of USD 7.1 million for
the approaching monetary year 2024-25.
·
The
committee likewise endorsed a preliminary measure that will permit ineligible
