Year 10 Geography: Environmental Change

Causes and Effects of Climate Change

Page 1: Overview of Climate Change

• Environmental Change and its implications.

• Emphasis on the need to understand causes and effects of climate change.

Page 2: Climate Change Context

• Tony Abbott: 28th Prime Minister of Australia (2013-2015).

• Leader of the Liberal Party during critical climate policy discussions.

Page 3: Lesson Objectives

1. Explain the causes and effects of climate change.

2. Distinguish between the greenhouse effect and the enhanced greenhouse effect.

3. Maintain respectful classroom dynamics and kindness towards Miss Taylor.

Page 4: Key Terms and Concepts

• Fossil Fuels:

  • Carbon-based fuels formed over millions of years (coal, petroleum, natural gas).

  • Classified as non-renewable; faster depletion than formation.

  • Australian Government subsidies: $12 billion annually.

• Green Energy:

  • Renewable sources (wind, solar, tidal), projected $2.8 billion subsidies by 2030.

• Industrial Revolution:

  • Initiated around 1750 in the UK, led to technological advancements across sectors and increased reliance on fossil fuels.

Page 5: Climate Definition

• Climate: Long-term weather patterns in specific areas, affecting biodiversity and ecosystem dynamics.

• Latitude’s Role:

  • Determines sunlight exposure, impacting temperature and rainfall patterns.

Page 6: Understanding Climate Change

• Causes of Climate Change: Human activities leading to greenhouse gas emissions.

• Effects of Climate Change: Broad spectrum of environmental impacts.

Page 7: Geological Time Perspective on Climate Change

• Natural climate variations over millions of years contrasted with recent human-induced changes.

• Increased greenhouse gas concentrations primarily due to fossil fuel combustion.

• Resulting consequences: Global warming and environmental changes across biophysical systems.

Page 8: Greenhouse Effect Explanation

• Natural Greenhouse Effect:

  • Essential for maintaining Earth’s temperature.

  • Video resource provided for visual understanding.

Page 9: Glossary Additions

• Enhanced Greenhouse Effect:

  • Recent, observable trend of rising world temperatures.

• Climate Change:

  • Changes in climate over time, influenced by natural or human actions.

Page 10: Differentiation of Greenhouse Effects

• Natural Greenhouse Effect:

  • Maintains Earth’s average temperature around 15°C.

• Enhanced Greenhouse Effect:

  • Increased greenhouse gas emissions due to human activities, leading to higher global temperatures.

Page 11: In-depth Look at Greenhouse Effects

• Natural vs Enhanced Greenhouse Effect:

  • GHGs trap solar radiation; natural process regulated by nature.

  • Enhanced process leads to excessive heat retention, driven by human activity.

Page 12: Understanding Emissions Context

• Human-induced Emissions:

  • Rising global temperatures driven by human activities, especially fossil fuel combustion.

Page 13: Carbon Emission Trends

• Chart evidence documenting the rise of carbon emissions from fossil fuels from 1900 to 2014.

Page 14: Analyzing Emissions Sources

1. Identification of human activities contributing to GHG emissions.

2. Ranking based on emission levels:

   • Prioritization of strategies to target for reduction.

Page 15: Continued Analysis of Emissions

• Review of human activities leading to GHG emissions, reinforcing understanding of mitigation potential.

Page 16: Key Causes and Effects of Climate Change

• Causes: Burning of fossil fuels, agriculture, deforestation.

• Effects:

  • Bushfires, extreme storms, drought impacts on agriculture, increased flooding/landslides, rising sea levels, biodiversity loss.

Page 17: Gap-fill Exercise on Climate Change
