This Concept Map, created with IHMC CmapTools, has information related to: After the warming- RJ Lewis, Iron ???? CO2 production, principle of Show and Tell for development Writing lead to increased Trading, Techniques for saving water resulted in Civilization, Stopped raining in Petra, city abandoned due to lack of water ???? ~1000AD, Long warm summers, let survive through winter But little access to Timber 1300AD - temperature drop, route to greenland, iced over, Which altered the ocean's ability to trap carbon dioxide Analysed amount of CO2 inlayers of ice (gas bubbles in ice) From 1958 began to monitor Fossil fuel use Carbon Dioxide levels Average global temperature methane levels CFC levels, Trading in 3000BC change in weather resulted in Techniques for saving water, Europeans began building enclosed buildings, steep roofs and guttering (for rain), plaster, curtains kept out cold, small rooms heated by individual fires,CHIMNEYS!!! Lead to indoor activities Making own music, writing,, Began to use Coke (coal with impurities burnt out) Lead to invention of The steam engine/ steam power - industrial revolution, Electricity led to Mass production, 300BC warm and moist, mountain passes open results in exploration and trade routes between China, India, Egypt, Coal ???? CO2 production, turn from farmers into factory workers Rising temperatures warmer summers, milder winters, better crops, more farming, industrialisation, more workers, more money, more newleweds, more houses, more need for furniture (industry), trade routes between China, India, Egypt 500 AD, temperature went down again Stopped raining in Petra, city abandoned due to lack of water, planet goes around sun heat energy is trapped inside the earth's atmosphere, Favours those who can stand upright and see above grass Ice age forced to move to find food, The steam engine/ steam power - industrial revolution created new lifestyle Which altered the ocean's ability to trap carbon dioxide, History of human development needed to see predators Favours those who can stand upright and see above grass, trade routes between China, India, Egypt 500 AD, temperature went down again Huns -> freezing drough -> moved in on neighbours -> Domino Theory of migration -> Dark ages, ~1000AD Vikings and livestock moved in on greenland Long warm summers, let survive through winter
