3.3 Topic 5: On the wild side
Discuss how understanding the carbon cycle can lead to methods to reduce atmospheric levels of carbon dioxide (including the use of biofuels and reforestation).
Outline the causes of global warming – including the role of greenhouse gases (carbon dioxide and methane, CH4) in the greenhouse effect.
Describe the effects of global warming (rising temperature, changing rainfall patterns and seasonal cycles) on plants and animals (distribution of species, development and life cycles).
Explain the effect of increasing temperature on the rate of enzyme activity in plants, animals and microorganisms.
Describe how to investigate the effects of temperature on the development of organisms (e.g. seeding growth rate, brine shrimp hatch rates).
Analyse and interpret different types of evidence for global warming and its causes (including records of carbon dioxide levels, temperature records, pollen in peat bogs and dendrochronology) recognising correlations and causal relationships.
Describe that data can be extrapolated to make predictions, that these are used in models of future global warming, and that these models have limitations.
Discuss the way in which scientific conclusions about controversial issues, such as what actions should be taken to reduce global warming or the degree to which humans are affecting global warming, can sometimes depend on who is reaching the conclusions.

2.3.4 Maintaining biodiversity
Maintaining biodiversity is important for many reasons.
Actions to maintain biodiversity must be taken at local, national and global levels.
(b) Discuss the consequences of global climate change on the biodiversity of plants and animals, with reference to changing patterns of agriculture and spread of disease.

Unit BY5: Environment, Genetics and Evolution
5.8 Effects of human activities and sustainability
Global warming and climate change affect distribution of species and are a possible cause of extinction. Possible need for changes in farming practices such as growing drought-resistant crops.
