Study Notes

Global Consequences of Climate Change

  • The 20th century was marked by significant technological advancement, but its lasting impact on the planet is increasingly evident.
  • Global warming and climate change are major consequences of heavy industrialization.
  • Global warming became apparent in the mid-20th century, with a 1°C rise in Earth's surface temperature since the 1970s.
  • Global warming is currently occurring at a rate of roughly 0.2°C per decade.
  • The primary cause of global warming is human activity.
  • The consequences of climate change are likely to be irreversible and severe.

Heating of Earth's Atmosphere

  • The most immediate consequence is a warming atmosphere, leading to less frequent cold days and more frequent hot days.
  • Plants and animals will face adaptations to survive in these changing conditions.
  • Species unable to adapt might become extinct.

Melting of Continental Ice

  • Rising temperatures melt continental ice, causing sea levels to rise significantly.
  • Flooding and destruction of coastal areas are potential consequences.

Increased Humidity & Extreme Weather

  • Warmer temperatures lead to increased water evaporation, resulting in higher humidity levels.
  • Extreme weather events, like wildfires, floods, and tropical cyclones, become more frequent and intense.

Ocean Oxygen Levels

  • Warming ocean water holds less oxygen, negatively affecting marine life.
  • Many underwater species face risk of extinction or require adaptation.

Human Responsibility & Mitigation

  • Humans are major contributors to climate change through fossil fuel burning.
  • Transitioning to renewable energy sources and improving energy efficiency can mitigate the impact.
  • Adaptation strategies are crucial, including reinforcing coastlines, relocating communities, developing weather-resistant crops, and contingency plans for disaster management.
