Edexcel A Level Biology A - Topic 5 - Global Warming (2/3)

A* Level notes covering the Greenhouse Effect and Global warming. Including:

• definition and causes of the greenhouse effect
• definition and causes of global warming
• the difference between the greenhouse effect and global warming
• the evidence for climate change (temperature, carbon dioxide, methane, pollen in peat bogs, dendrochronology, ice cores)
• how we can extrapolate data on climate change
• the limits of the evidence over climate change
• the impact of climate change on enzymes
• the carbon cycle (how fossil fuels are formed, the role of microorganisms, carbon sinks, the impact of slash and burn farming)
• the role and impact of bio fuels and reforestation to offset climate change
• the core practical about the impact of increasing temperature on the rate of enzyme-catalysed reaction.
