Breakup of Antarctica’s Ross Ice Shelf
• An iceberg (B-15J) of size of a small United States state cracked off the Antarctica’s Ross Ice Shelf in March 2000
• On February 1, 2007, three new icebergs were formed due to the break up of the original iceberg

INITIATIVES
• INTERNATIONAL LEVEL• NATIONAL LEVEL
INITIATIVES AT INTERNATIONAL LEVEL
• 1988 – IPCC ( WMO &UNEP)• 1992 – UNFCCC (United Nations Framework
Convention on Climate Change)• 1997, 2008 - KYOTO PROTOCOL• MDG 7 : “Ensure environmental sustainability”• 2009 – Copenhagen conference
United Nations FrameworkConvention on Climate Change
Passed in June 1992 in Rio de Janeiro at “Earth Summit”
• Earliest international legislation regarding climate change
• Aimed at stabilizing greenhouse gas concentrations in atmosphere to prevent anthropogenic climate change
• Established National Greenhouse Gas Inventory, which requires nations to submit mandatory accounts of emissions
• Legally binding
The Kyoto Protocol
• Dec 11, 1997, by 3rd Conference in an attempt to rectify mistakes of UNFCCC
• Attempts to mitigate the effects of global warming• Covered 182 countries – May 2008, which translates into
60% of carbon emissions• United States: Signed but did not ratify the treaty
The Kyoto Protocol (cont.)
• Two categories:• • Annex I (developed countries):
• Includes most of Europe, North America, and Japan, among others• Required to reduce greenhouse gas emissions and submit an annual report
• • Non-Annex I (developing countries):• Includes China, Brazil, and India, among others• No requirements
• Annex I countries are required on average to reduce emissions to 5% below the 1990 level by 2012
• Carbon credits will eventually be issued to all countries, and then allowed to be traded
• Failure to comply results in a country having to submit 1.3 “emissions allowances”
The Kyoto Protocol (cont.)
• Shortcomings:• Not aggressive enough• Not ratified by the United States• Large emitters including China, Brazil &India are under no obligation to reduce
emissions• Dec 2009 – Copenhagen conference
INITIATIVES AT NATIONAL LEVEL
• Mr. Shyam Saran, Special Envoy of Prime Minister for Climate Change
National Action Plan on Climate Change
• Plan has Eight broad areas for focused action, encompassing bothmitigation & adaptation.
1. National Solar Mission2. National Mission for Enhanced Energy Efficiency3. National Mission on Sustainable Habitat4. National Water Mission5. National Mission for Sustaining the Himalayan Ecosystem6. National Mission for a “Green India”7. National Mission for Sustainable Agriculture8. National Mission on Strategic Knowledge for Climate Change
• India is increasing its forest cover and intends to raise it from the current 22% of total land area to 33%.
