    Cards (68)

    • Match the cause with its primary focus:
      Climate Change ↔️ Natural variations and human activities
      Global Warming ↔️ Human greenhouse gas emissions
    • What information do ice cores provide about past climates?
      Temperature, precipitation, atmospheric composition
    • Satellite data shows decreases in ice cover
    • Ice cores from glaciers contain air bubbles and materials that show past temperature and atmospheric composition
    • What is one effect of extreme weather events, as current evidence of climate change indicates?
      Increased drought frequency
    • What does current evidence of climate change support?
      Scientific consensus on reality
    • Natural causes have a greater impact on climate change than human activities.
      False
    • Agricultural practices like livestock farming and fertilizer use emit methane and nitrous oxide, which are potent greenhouse gases.

      True
    • Ship logs and weather observations are examples of historical documents used to study past climate events.
    • Satellite data indicates increases in sea levels and decreases in ice cover.

      True
    • Volcanic eruptions release greenhouse gases and aerosols, which can cause short-term cooling followed by warming.
    • Livestock farming and fertilizer use emit methane and nitrous oxide, which are potent greenhouse gases
    • The carbon cycle acts as a positive feedback by releasing more CO2 from warming soil
    • Climate change refers to the long-term alteration of average weather patterns
    • Layers of sediment in lakes and oceans are known as sediment records
    • Extreme weather events like heatwaves and droughts are becoming more frequent and intense
    • Match the natural or human cause of climate change with its impact:
      Deforestation ↔️ Loss of CO2 sinks, higher atmospheric CO2
      Agricultural Practices ↔️ Emit potent greenhouse gases
    • "Global Warming" is a specific aspect of climate change that focuses solely on the increase in Earth's average surface temperature
    • What are some effects of climate change?
      Changes in precipitation
    • Historical data sources allow scientists to analyze climate patterns over centuries and millennia.

      True
    • Global warming is a broad term that encompasses all aspects of climate change.
      False
    • What do historical documents such as ship logs provide insights into?
      Past climate events
    • Satellite data shows increases in sea levels, decreases in ice cover
    • Increased solar activity can slightly warm the planet
    • What is the major greenhouse gas released by fossil fuel combustion?
      CO2
    • Match the historical data type with its contribution to climate change understanding:
      Ice cores ↔️ Shows past temperature and atmospheric composition
      Tree rings ↔️ Indicates past temperature and precipitation
      Sediment records ↔️ Contains climate information from lakes and oceans
      Historical documents ↔️ Provides insights into past climate events
    • Order the types of current evidence used to study climate change based on their primary focus:
      1️⃣ Instrumental records: Climate variables
