This section deals with the impacts of climate change on ozone loss, which is projected to surpass that caused by chlorofluorocarbons (CFCs) in the upcoming decades. In addition, considering that ozone-depleting substances are also potent greenhouse gases, issues covered include those related to efforts carried out under the Montreal Protocol, notably the phase-out of CFCs, which is greatly reducing emissions of carbon dioxide equivalent and delaying climate change.
14 May 2008: UN Secretary-General Ban Ki-moon, in his capacity as depositary of the Montreal Protocol on Substances that Deplete the Ozone Layer, has advised parties that the adjustments made to the Montreal Protocol at the Nineteenth Meeting of the Parties to the Protocol (17-21 September 2007) will enter into force, and become binding to all parties, on 14 May 2008.
The Swiss Global Climate Observing System (GCOS) Office has compiled the first inventory of the country's long-term climate data.
Delivering as one in space-related activities was one of the main issues discussed during the 28th session of the United Nations Inter-Agency Meeting on Outer Space Activities, held from 16-18 January 2008 at the Palais des Nations in Geneva, Switzerland.
25 November 2008: The World Meteorological Organization (WMO) has released the 2007 Greenhouse Gas Bulletin, which indicates that the trend of rising emissions of greenhouse gases continued during that year.
25 November 2008: According to research conducted by CarboAfrica, an international research consortium of 15 institutions from Africa and Europe that includes the UN Food and Agriculture Organization (FAO), Africa could be absorbing more carbon from the atmosphere than it emits.
21 November 2008: The eighth Conference of the Parties to the Vienna Convention for the Protection of the Ozone Layer and the 20th Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (COP 8/MOP 20) took place in Doha, Qatar, from 16-20 November 2008.
13 November 2008: The UN Environment Programme (UNEP)
released a report on Atmospheric Brown Clouds (ABCs) that shows that, in
addition to affecting agriculture and human health, this layer of soot and
manmade particles can both aggravate, via the absorption of sunlight, and
counteract, via the reflection of sunlight and effects on cloud formation,
climate change due to greenhouse gases.
16 September 2008: International Day for the Preservation of
the Ozone Layer was celebrated on 16 September 2008, with the theme "Montreal
Protocol – Global partnership for global benefits." In the UN Secretary-General's message
recognizing the day, Ban Ki-moon emphasized that the success of the Protocol
demonstrates that environmental protection can be sustained through economic
downturns, and encouraged governments to look for synergies among multilateral
environmental agreements as the Parties to the Protocol did when deciding to
accelerate the phase-out of hydrochlorofluorocarbons.
16 September 2008: Marking International Day for the
Preservation of the Ozone Layer, which was celebrated on 16 September 2008, the
World Meteorological Organization (WMO) released data showing that the ozone
hole is already larger in 2008 than it was in 2007, emphasized that the need
for continued ozone measurements to monitor the ozone hole, and highlighted the
Montreal Protocol's climate benefits.
16 September 2008: On the occasion of the International Day
for the Preservation of the Ozone Layer, Ahmed Djoghlaf, Executive Secretary of
the Convention on Biological Diversity (CBD), noted the success that the
Montreal Protocol has achieved through international cooperation.
