,Covered in this presentation
• 5.12 Understand the different types of evidence for climate change and its causes (including records of carbon
dioxide levels, temperature records, pollen in peat bogs and dendrochronology) recognizing correlations and c
relationships.
• 5.13 Understand the causes of anthropogenic climate change, including the role of greenhouse gases (carbon
dioxide and methane) in the greenhouse effect.
• 5.14 Understand that data can be extrapolated to make predictions and that these are used in models of futu
climate change. Understand that models for climate change have limitations.
• 5.15 Understand the effects of climate change (changing rainfall patterns and changes in seasonal cycles) on p
and animals (distribution of species, development and life cycles).
• 5.16 Understand the effect of temperature on the rate of enzyme activity and its impact on plants, animals an
microorganisms.
• 5.20 Understand the way in which scientific conclusions, such as what actions should be taken to reduce clima
change or the degree to which humans are affecting climate change, can sometimes depend on who is reachi
the conclusions.
• 5.21 Understand how knowledge of the carbon cycle can be applied to methods to reduce atmospheric levels
carbon dioxide.
• 5.22 Understand how reforestation and the use of sustainable resources, including biofuels, are examples on t
effective management of the conflict between human needs and conservation.
, Understanding how to learn
Our presentations use the ‘forgetting curve’ study method. So, there w
be repetition within the slides and the same questions asked twice. Th
is because that way you are less likely to forget something.
The clock slides mean there is a short recap question on what you learnt.
The star symbol means there is an exam question to answer.
, Let’s begin: Evidence for climate change
It is one of the biggest challenges facing ecosystems today.
Is the climate really changing and has it changed in the past?
Evidence from personal memory is termed anectodal; it is often
unreliable. We cannot rely on anecdotal reports; we need reliable
scientific evidence.
