Study Notes

Climate Change

  • Climate change involves long-term shifts in temperatures, precipitation, and atmospheric conditions on Earth.
  • Human activities, primarily the burning of fossil fuels, deforestation, and industrial processes, drive modern-day climate change, significantly increasing greenhouse gas concentrations since the 1800s.
  • Burning fossil fuels releases heat-trapping gases like carbon dioxide and methane, triggering the greenhouse effect.
  • Increased greenhouse gas concentrations cause global warming, impacting temperature and precipitation patterns.
  • Observed impacts include rising global temperatures, melting glaciers and ice sheets, rising sea levels, altered precipitation patterns, and more frequent and intense extreme weather events (heatwaves, droughts, floods, storms).
  • Climate change profoundly affects ecosystems, biodiversity, agriculture, water resources, and human health.
  • Melting glaciers and polar ice caps contribute to rising sea levels, threatening coastal communities and ecosystems.
  • Changes in precipitation patterns impact agriculture, water resources, and biodiversity.
  • Ocean acidification, caused by increased carbon dioxide absorption, harms marine organisms, especially shellfish and coral reefs.
  • Shifts in temperature and precipitation influence the distribution and abundance of plant and animal species, disrupting ecological balance.
  • Increased frequency of extreme weather events leads to substantial economic losses and humanitarian crises.
  • Disrupted migration patterns of animals and insects affect food webs and ecosystem functioning.
  • Earth's climate has changed over millions of years, naturally experiencing hotter and colder periods.
  • Examples include a period 60 million years ago with high volcanic activity, increased carbon dioxide and methane, and warmer temperatures allowing giant tortoises and alligators to thrive in the Arctic.
  • Past Ice Ages, lasting much longer than glaciations, resulted from changes in Earth's orbit around the Sun, solar activity, and living things' activities.
  • The current global warming is primarily caused by human activity and substantially stronger than changes due to solar activity.
  • Research shows a minimal change in solar energy output over the past 40 years and over 270 times greater warming from greenhouse gases compared to solar variation in the past 250 years.
  • Important scientists like Joseph Fourier, Claude Pouillet, Eunice Foote, John Tyndall, Svante Arrhenius, and Guy Stewart Callendar recognized the role of carbon dioxide (CO2) in climate change. Foote's work was not widely known, and Tyndall proved the existence of other greenhouse gases. Nils Gustaf Ekholm in 1901 coined the term 'greenhouse effect'.
  • The 11-year sunspot cycle has a negligible effect on Earth's temperature.

Ecological Overshoot

  • Ecological overshoot occurs when human demands on resources exceed Earth's regeneration capacity.
  • This overconsumption from resource use, deforestation, and pollution surpasses the planet's ability to replenish itself.
  • Key indicators include exceeding Earth's biocapacity.
  • This leads to environmental damage, diminished resources, intensified ecosystem strain, and biodiversity loss.
  • Human consumption exceeds regenerative capacity, depleting resources faster than nature can replace them.
  • Unsustainable consumption can cause resource scarcity, increased risks of disease, and societal unrest, especially in vulnerable regions.
  • Overshoot is measured by comparing human demand with the Earth's ecological capacity.
  • Factors include population growth, consumption patterns, and inefficient resource use.
  • The concept is interconnected with the ecological footprint.

Pollution

  • Pollution introduces harmful substances into the environment, manifesting as air, water, and soil contamination.
  • Pollution sources are both natural and anthropogenic.
    • Anthropogenic pollution disrupts ecological cycles.
  • Air pollution, from industrial emissions, vehicles, and agriculture, causes respiratory and cardiovascular issues.
  • Water pollution, from industrial waste, agricultural runoff, sewage, and plastics, contaminates water sources, harming marine life and humans.
  • Soil pollution from industrial waste and chemicals harms plant life and the food chain.
  • Pollution alters ecosystems, reduces biodiversity, damages human health, and impacts economies.
  • Solutions include clean technology, stricter environmental laws, and public awareness.

Renewable Energy

  • Renewable energy sources naturally replenish unlike fossil fuels.
  • Examples include solar, wind, hydro, geothermal, and biomass.
  • Solar energy harnesses sunlight using photovoltaic panels or concentrated solar power systems.
  • Wind energy converts wind's kinetic energy into electricity using wind turbines.
  • Hydropower uses flowing water to generate electricity.
  • Geothermal energy taps Earth's internal heat.
  • Biomass energy utilizes organic matter (wood, crops).
  • These sources are environmentally friendly and reduce reliance on finite fossil fuels.
  • Energy storage solutions manage the intermittent nature of some renewables (solar, wind).

Carbon Footprint

  • A carbon footprint is the total greenhouse gas emissions (primarily carbon dioxide) from an individual, organization, event, or product.
  • It measures the impact of human activities on climate change.
  • Calculating carbon footprints involves assessing emissions from various sources (transportation, energy, food, waste).
  • Methodologies vary in complexity; standardized guidelines often calculate a "carbon footprint per unit" of activity.
  • Reduced consumption and improved efficiency lower carbon footprints.

Sustainability

  • Sustainability satisfies present needs without compromising future generations' ability to meet theirs, encompassing environmental, social, and economic dimensions.
  • Key components include environmental protection, social equity, and economic viability.
  • Sustainable development balances economic growth, social progress, and environmental protection.
  • Sustainable practices require changes in consumption, production, and government policies.
