Propose an investigation of historical data to show how climates are changing. Examples could include the Keeling Curve, global temperature and CO2 ppm values from the Vostok ice core. Ask students to consider the relevance of such evidence to the UK climate and ecosystems. They should appreciate that ecosystems exist at different scales, and discuss the impact of changing flora and fauna, relating this to changes in agricultural patterns, eg growing seasons. Using the Millennium Ecosystem Assessment, explore the likely consequences of a changing climate on ecosystems and people. Students could research the role of the flora and fauna described in the clip within food chains and webs.
