Study Notes
Climate Change and the Environment
- CO2 emissions from fossil fuels increased sixfold between 1950 and 2020
- High-income countries still have large CO2 emissions but China's share has substantially increased
- Per capita CO2 emissions are high in wealthy and oil-producing nations
- CO2 remains in the atmosphere for a long time, needing consideration of cumulative emissions
- Land use change contributes to CO2 emissions, but fossil fuels are the main source
- Annual CO2 emissions began increasing with the industrial revolution, with a major rise after 1950 due to population growth and development
- Currently, China has the largest emissions, followed by the USA, then Europe
- Wealthier nations contribute disproportionately more to global emissions, compared to low-income countries
Greenhouse Gases and Climate Change
- Climate change is not new, but human-caused change is
- Past periods included ice ages and warmer interglacial periods
- Possible causes for climate change include sunspots, volcanic activity, variations in Earth's orbit, and now increased fossil fuel emissions
- Fossil fuels have a significant impact on climate change
- Global average temperatures have risen by 1.1°C since the late 19th century
- Melting ice sheets and glaciers, decreasing snow cover and sea level rise are all effects
- Future climate changes include rising temperatures, altered precipitation patterns, lengthening frost-free seasons, more intense droughts and heat waves, stronger hurricanes, and rising sea levels
- The impacts are regional, with different areas experiencing increasing precipitation, extreme dryness, and varying water stress
UN Conferences and Environmental Concerns
- The Stockholm conference in 1972 marked the first major international gathering focused on the environment
- The 1982 Nairobi conference focused on environmental conservation and global awareness related to environmental issues
- The 1992 Rio de Janeiro Earth Summit (UNCED) led to treaties on global warming, biodiversity, and desertification, as well as discussing sustainable development
- The 2002 Johannesburg World Summit on Sustainable Development emphasized environmental concerns
- The Rio+20 summit in 2012 showed a renewed commitment to sustainable development and alternatives to calculating welfare with GDP
- More recent conferences such as COP26 and COP27 continued the efforts to mitigate climate change, but with limited actual progress to meet goals
Environmental Issues
- Air pollution, notably smog, in cities like New Delhi and China, still pose significant health risks
- Airborne lead, a persistent environmental concern, remains a major hazard, especially for children
- Acid rain, driven by fossil fuel emissions, damages building, trees, and ecosystems due to increased sulfur and nitrogen oxides in the air
- Ozone depletion is a concern primarily over the poles and is directly influenced by CFC emissions, causing serious harm to the environment
- Water pollution from sewage, chemicals, and agricultural runoff is a critical problem, especially in developing countries. Water scarcity is an issue, with conflicts potentially emerging over limited resources
- Overuse of minerals, deforestation, and land degradation are significant environmental concerns
- An alarming trend is the ongoing decline of species diversity, raising concerns over the extinction levels, with some species endangered.
Environmental Politics
- Environmental politics can be emotionally charged, rooted in differing worldviews regarding human's relationship with nature
- A more exploitative view sees humans at the center of the environment, while the mutualistic worldview recognizes the need to adapt and safeguard nature
- Environmental challenges disproportionately affect lower-income communities, often seen as hurdles to economic progress and well-being
