Study Notes
Human Activities and Climate Change
- Global warming is the increase in Earth's average temperature due to greenhouse gases trapping heat that would normally escape into space.
- The greenhouse effect is the warming effect caused by greenhouse gases absorbing and reflecting heat radiated by Earth, preventing it from escaping into space.
- Climate change is a broader term encompassing various changes in temperature, precipitation, and other environmental factors. Even a 1°C change can significantly impact climates. By the end of the century, the Earth may be as much as 4°C warmer.
- Greenhouse gases include water vapor, carbon dioxide, methane, ozone, and nitrous oxide.
- Burning fossil fuels (coal, oil, and gas) is a major source of carbon dioxide emissions, contributing significantly to the problem. Deforestation also adds to this problem since trees absorb carbon dioxide.
- Methane (CH4) is a potent greenhouse gas produced by various activities, including agriculture and waste management.
- Other human activities increasing greenhouse gas emissions include industrial processes, transportation, and waste disposal.
Annual Greenhouse Gas Emissions by Sector
- A breakdown (pie chart not provided with data) shows the annual greenhouse gas emissions by sector (e.g., power stations, transportation, agricultural byproducts, industrial processes,etc.)
Impacts of Climate Change
Globally
- Rising temperatures lead to more intense storms (e.g., hurricanes, tornadoes).
- Increased flooding and droughts due to changing weather patterns.
- Food shortages and loss of biodiversity as weather patterns and oceans change.
- Worsening health risks because changing weather patterns affect the spread of diseases.
Locally
- Increased urban heat island effect from concrete absorbing heat.
- Decline in water supplies and agricultural production.
- Rising sea levels and localized flooding in coastal areas.
- Increased insurance costs and/or denial of insurance in high-risk regions.
Indigenous People
- Loss of access to traditional foods and land.
- Limited access to safe drinking water.
- Loss of cultural identity and traditional practices.
- Climate change effects are most severe in Arctic regions, leading to melting permafrost and difficulties for hunters
Global Warming
- Burning fossil fuels (coal, oil, and gas) produces carbon dioxide (CO2).
- Last year, the world burned 97 million barrels of oil products per day
- This translates to 354 billion barrels consumed per year (3.54 billion).
- CO2 prevents the Sun's energy from reflecting back into space, warming the Earth.
- Global warming causes changes in weather patterns around the globe.
- Solutions to lower global CO2 emissions include burning less fossil fuels.
Global Initiatives to Combat Climate Change
- Putting a price on pollution, like carbon taxes.
- Implementing renewable energy (wind, solar, tidal, geothermal)
- Improving transportation efficiency
- Using energy-efficient appliances and buildings.
- Reducing, reusing, repairing, recycling, and refusing products.
