Climate Change Flashcards
What is the greenhouse effect?
Where greenhouse gases such as carbon dioxide and methane absorb outgoing heat so less is lost in space.
What are orbital changes?
Variations in the way the Earth moves around the Sun. They affect the amount of solar radiation the Earth receives.
Name 4 human activities that contribute to climate change
Burning fossil fuels
Deforestation
Waste to landfill
Agriculture
Name 4 pieces of evidence used when measuring climate change
Thermometer readings
Ice cores
Glacial retreat
Tree rings
Name 3 impacts of climate change on the UK
sea levels could rise, covering low lying areas, in particular east England
droughts and floods become more likely as extreme weather increases
increased demand for water in hotter summers puts pressure on water supplies
Name 4 international impacts of climate change
sea level rise will affect 80 million people
tropical storms will increase in magnitude (strength)
species in affected areas (eg Arctic) may become extinct
diseases such as malaria increase, an additional 280 million people may be affected
What is mitigation?
Reduce or prevent the effects of something from happening
Suggest 3 ways we can mitigate against climate change
International agreements
Afforestation
Alternative energy production
What is adaptation (in relation to climate change)
Adaptation strategies do not aim to reduce or stop global warming. Instead they aim to respond to climate change by limiting its negative effects.
How can we adapt to climate change?
Agriculture - farmers will have to adapt as some crops may not be able to grow in a warmer climate. However, other crops (eg oranges and grapes) will be able to be planted.
Water supply - water transfer schemes could be used. This is where water is transferred from an area of water surplus to an area of water shortage.
Reducing risk from sea level rise - areas at risk from sea level rise may use sea defenses to protect the land from being eroded away.
What is climate change?
A long-term alteration in temperature and typical weather patterns in a place.
True or False: Climate change only affects temperature.
False
What are greenhouse gases?
Gases that trap heat in the atmosphere, such as carbon dioxide and methane.
Fill in the blank: The main greenhouse gas produced by human activities is __________.
carbon dioxide
What is the greenhouse effect?
The process by which greenhouse gases trap heat in the Earth’s atmosphere.
Which human activity is a major contributor to climate change?
Burning fossil fuels.
True or False: Deforestation contributes to climate change.
True
What is global warming?
The increase in Earth’s average surface temperature due to rising levels of greenhouse gases.
Fill in the blank: __________ is a consequence of climate change that affects sea levels.
Melting ice caps
What is one impact of climate change on weather patterns?
Increased frequency of extreme weather events.
True or False: Climate change can lead to loss of biodiversity.
True
What is adaptation in the context of climate change?
Adjusting practices, processes, and structures to minimize damage from climate change.
What is mitigation in terms of climate change?
Efforts to reduce or prevent the emission of greenhouse gases.
Which international agreement aims to combat climate change?
The Paris Agreement.
