Presentation transcript:

Global warming & greenhouse gases CO2, methane, nitrous oxides, CFCs Climate Change You need to know: Causes & effects Climate Change in the past! Can you describe patterns and trends from a graph like the one below? Include key dates Keywords: Inter-glacial, glacial, increase Can you describe maps? Key Hint: name regions, state facts, trends and odd facts Bangladesh How is it going to be affected? Flooding – from sea and heavy rains Natural Causes: volcanoes sunspots earth’s orbit Can you remember whether they warmed or cooled the planet. Can you also explain what happens for each cause? UK How is it going to be affected? Flooding – from sea and heavy rains but also solar energy, farming & tourism effects Mega fauna extinction & Little Ice Age Can you describe what caused each event? Can you describe the impacts/effects of each event? Can you explain why its important to study past climate change events?
