Office Hadley Centre 14 2/11/2013 The Greenhouse Effect Sunlight enters the Earth's atmosphere, passing through a layer of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Energy absorbed is sent back into the atmosphere.
Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing the world to heat up. Human activities have increased substantially the concentration of greenhouse gases (carbon dioxide, methane, CFCs, HCFCs, nitrous oxide). As a result, a substantial warming of the earth surface and atmosphere occurred that might adversely affect the natural ecosystem. Over the last hundred years, the mean temperatures have increased by 0. 3±0. 68C. Doubling the amount of carbon dioxide in the atmosphere is likely to yield a further temperature increase by 1. 5±4. 58C.
If no action is taken to reduce greenhouse gas emissions, the rate of growth of the aver- age temperatures is likely to exceed that which occurred in the last 10,000 years [Houghton, 1995] Global costs of extreme weather events (inflation adjusted) • Total economic losses and number of events have been incresing over the decades • Within the last decade, 72 major events occurred, close to 100% increase over the 1980-1990 decade. Climate Change • Climate Change is not a new issue. In the early 1980s scientific consensus grew - climate change was a critical global issue. Following from this, governments established the Intergovernmental
Panel on Climate Change (IPCC) in 1988 to help them understand and build some international consensus on the nature of the problem. 15 2/11/2013 Is the link with CO2 and other GHG’s confirmed? • The Inter-governmental Panel on Climate Change in its most recent report stated: 'the balance of evidence suggests a discernible human influence on the climate system.

Europe and North America. These efforts mirrored domestic environmental policy developments and were often concerned with wildlife conservation. International Efforts pre-1960 • 1872: Swiss propose international commission to protect migratory birds • 1900: First formal agreement: Convention for the Preservation of Animals, Birds and Fish in Africa, signed in London by European colonial powers with the intent to protect African game species, especially to limit export of ivory to reduce severe hunting pressure on African elephant • 1900: European states sign treaty to regulate transportation of toxic substances on Rhine River 1909: Canada-US Boundary Waters Treaty • 1911: North Pacific Fur Seal Commission established by USA, Canada, USSR and Japan to regulate harvest of seals in North Pacific • 1918: US-Canada Migratory Bird Treaty Act, designed to protect bird species–esp. waterfowl--that seasonally migrate between the two nations Early International Efforts, cont’d • 1931: First efforts to regulate commercial whaling, led (in 1946) to International Convention for the Regulation of Whaling and establishment of International Whaling Commission, a permanent body responsible for negotiating & setting policy re- the harvest and preservation of whales. 1940: Convention on Nature Protection and Wildlife Conservation in the Western Hemisphere • 1946: Founding of the United Nations and World Bank, which would play leading roles in international environmental cooperation (World Bank, UNIMO, FAO, UNDP, WHO, UNEP & UNESCO) • 1954: International Convention for the Prevention of Pollution of the Sea by Oil, culmination of 28 years of negotiations by European and N. A. nations • 1958: International Maritime Consultative Organization (UN-IMCO) established with responsibility for negotiating international agreements on ocean pollution 19 2/11/2013 International Efforts (1960-1972)
Context: Increase in international environmental efforts mirrored rise in Modern Environmental Movement in west • Cumulative environmental effects of Post-war boom (industrialization, prosperity, consumerism) • Affluence = greater concern over “quality of life” • New environmental science: e. g. , Rachel Carson “Silent Spring” published in 15 countries, 1962 • Growing media coverage of environmental events e. g. 1954 London “Killer Smog”, 1959 Mercury poisoning in Minimata Bay, 1967 Torrey Canyon oil spill in the English Channel • Rise of Vietnam, civil rights & counter-culture protests against status quo Globalization of communication; increased recognition of interdependence among nations: Apollo 11 “Earth-rise” photo in 1969 Efforts 1960-72 , cont’d. • Creation of first prominent and truly international environmental NGO’s (e. g. , Greenpeace, WWF, etc. ) • Emergence of first “Green” political parties in New Zealand, Western Europe and Australia • Between 1970 and 1972: 14 industrialized nations established environmental ministries and passed significant environmental legislation (Environment Canada, Clean Water Act, Clean Air Act, etc. ) • But, little progress in LDC’s or Communist Bloc 1971: RAMSAR Convention on Wetlands of International Importance • 1972: UNESCO-sponsored Convention for the Protection of World Cultural and Natural Heritage. • 1972: Oslo Convention for the Prevention of Marine Pollution by Dumping from Ships and Aircraft. • 1972: US-Can Great Lakes Water Quality Agreement U. N. Stockholm Conference on the Human Environment (1972) UN General Assembly resolution to host international meeting “... to provide a framework for comprehensive consideration within the UN of the problems of the human environment in order to focus the attention of governments and public opinion on the mportance and urgency of this question” • Preparatory period dominated by Western, industrialized countries • Soviet bloc boycotted effort because of ideological differences and unrelated political conflicts • LDCs encouraged to participate, but remained skeptical: feared environmental initiatives might get in way of economic development priorities • LDCs willing to cooperate, but only if development interests were not compromised and the West assisted them with finances and technology to invest in environmental protection. Also disapproved with West’s fixation on need for LDC population control. 0 2/11/2013 Stockholm, cont’d 114 nations, 1200 delegates (2 heads of state)–large by UN standards. Much media coverage and 500 NGO’s participated in parallel “Environmental Forum”. Outcomes… • Stockholm Declaration of the UN Conference on the Human Environment: 26 principles, intended as a foundation for future developments in international environmental cooperation – established basic principles of international environmental law. • Action Plan for the Human Environment: 109 recommendations for govt and inter-govt. action on issues ranging from species onservation, forests and atmospheric and marine pollution, to development policy, human settlements, and technology transfer. • Established United Nations Environment Program (UNEP) and Environment Fund • Formal acknowledgment of Additionality Principle: wealthy North should pay for some or all of added costs of environmental initiatives in developing south • Emergence of environmental civil society movement as a significant international stakeholder Between Stockholm & Rio (1972-1992) Developed Western Nations: • Much progress with domestic legislation and programs had been made in the late 1960s/early 1970's.
The benefits of these efforts were being felt by the late 1970s, with improvements in water & air quality, reductions in toxins like lead & DDT, and increases in protected areas. Lesser Developed Nations: • Environmental conditions deteriorated severely: urban pollution & squaller, deforestation, soil erosion, water-born diseases. In spite of opposition at Stockholm, many LDCs began to respond by establishing environmental ministries & associated laws (from 11 nations in 1972 to 102 in 1980). As well, many moved ahead with aggressive population planning (e. g. India, China). Soviet Bloc: Environmental problems worsened: air & water pollution, nuclear contamination, environmental health & disease. • Had boycotted Stockholm and made limited progress afterward (economic growth remained the priority). Civic activism & information remained suppressed until the fall of Communism in late 1980's Between Stockholm and Rio, cont’d • 1972: London Convention for the Prevention of Marine Pollution by Dumping of Wastes (toxic & nuclear waste dumping at sea). • 1973: International Convention for the Prevention of Pollution from Ships (MARPOL). • 1973: Convention on the International Trade of Endangered Species (CITES). 1974: Paris & Helsinki Conventions to protect marine environments of the North and Baltic Seas. • 1974/84: 1st & 2nd UN Population Conferences. • 1979: Convention on Long-Range, Transboundary Air Pollution (LRTAP). Canada, US & Europe agreement to address concerns about acid rain; first major international effort to regulate air pollution. • 1980: IUCN/WWF/UNEP World Conservation Strategy. promoted conservation planning in LDCs. 21 2/11/2013 Cont’d… • 1982: UN Conference on the Law of the Sea (UNCLOS). 200 mile territorial jurisdictions established, etc. • 1982: IWC commercial whaling moratorium. 1987: Montreal Protocol on Substances that Deplete the Ozone Layer • 1988: Intergovernmental Panel on Climate Change formed by UNEP & WMO • 1989: Basel Convention on the Control of Trans-boundary Movements of Hazardous Wastes • 1991: Canada-US Air Quality Agreement to reduce SO2 emissions that cause acid rain • 1991: Protocol on Environmental Protection of Antarctica: moratorium on mineral and related exploration and development for 50 years • European Union: Broad progress on regional, international environmental cooperation pertaining to toxics, water quality, waste management, air pollution, wildlife protection and noise pollution
Rio Summit: UN Conference on Environment & Development (1992) Context: • “Rio Summit” needs to be seen in light of the rapid resurgence of environmental concern in the 1980s.
