5.4.3 Effects of Climate Change

• What is climate change primarily caused by?

  Human activities
• Climate change is driven by increased levels of greenhouse gases
• Global warming is a direct consequence of climate change.
• Order the greenhouse gases by their relative warming potential from highest to lowest

  1️⃣ Nitrous Oxide

  2️⃣ Methane

  3️⃣ Carbon Dioxide

  4️⃣ Water Vapor
• Match the greenhouse gas with its chemical formula:

  Carbon Dioxide ↔️ $CO_{2}$

  Methane ↔️ $CH_{4}$

  Nitrous Oxide ↔️ $N_{2}O$

  Water Vapor ↔️ $H_{2}O$
• What is the primary source of carbon dioxide emissions?

  Burning fossil fuels
• Deforestation reduces the number of trees that absorb carbon dioxide
• Methane emissions from livestock contribute to climate change.
• Which greenhouse gas is considered the most significant contributor to climate change?

  Carbon Dioxide
• Methane has a higher warming potential than carbon dioxide but a shorter lifespan.
• Which greenhouse gas affects the ozone layer?

  Nitrous Oxide
• Water vapor acts as a feedback mechanism that amplifies global warming
• Increased urbanization leads to more burning of fossil fuels and higher CO2 emissions.
• What effect does climate change have on polar ice caps?

  Melting
• Rising sea levels are a consequence of melting polar ice caps due to climate change
• Order the effects of climate change on ecosystems from most widespread to most severe:

  1️⃣ Biodiversity Loss

  2️⃣ Habitat Alteration

  3️⃣ Species Migration

  4️⃣ Increased Extinction Risk
• Match the effect of climate change with its consequence:

  Biodiversity Loss ↔️ Coral reef bleaching

  Habitat Alteration ↔️ Melting Arctic ice

  Species Migration ↔️ Birds migrate earlier

  Increased Extinction Risk ↔️ Plant species struggle to adapt
• Melting Arctic ice reduces the habitat and food sources for polar bears.
• Birds migrate earlier in the year due to warmer temperatures
• Some plant species struggle to adapt to rapidly changing climates
• What is the primary cause of climate change?

  Human activities
• Carbon dioxide is released by burning fossil fuels and deforestation
• Methane has a higher warming potential than carbon dioxide but a shorter atmospheric lifespan
• Match the greenhouse gas with its primary source:

  Carbon Dioxide ↔️ Burning fossil fuels

  Methane ↔️ Agriculture

  Nitrous Oxide ↔️ Industrial processes
• What effect does the greenhouse effect have on global temperature?

  It increases global temperature
• Order the effects of climate change on ecosystems:

  1️⃣ Biodiversity Loss

  2️⃣ Habitat Alteration

  3️⃣ Species Migration

  4️⃣ Increased Extinction Risk
• Climate change affects agriculture through altered weather patterns and decreased crop yields
• What is an example of rising sea levels affecting coastal areas?

  Increased flooding in Miami
• Match the greenhouse gas with its chemical formula:

  Carbon Dioxide ↔️ $CO_{2}$

  Methane ↔️ $CH_{4}$

  Nitrous Oxide ↔️ $N_{2}O$

  Water Vapor ↔️ $H_{2}O$
• What is the greenhouse effect responsible for in the atmosphere?

  Trapping heat
• Order the effects of climate change on ecosystems:

  1️⃣ Biodiversity Loss

  2️⃣ Habitat Alteration

  3️⃣ Species Migration

  4️⃣ Increased Extinction Risk
• Climate change affects agriculture primarily through altered weather patterns and decreased crop yields
• What is an example of rising sea levels affecting coastal areas?

  Increased flooding in Miami
• The increasing frequency and intensity of extreme weather events are linked to climate change
• Increased flooding in Bangladesh is an example of climate change affecting infrastructure
