Geography Notes
thank yichyi for helping (2D) and dun blame the person who forgot to give out the geog notes. Thank you. (:
ms goh only gave notes for global warming, duno why also, 2G also said that Unit 33 not tested Global warming= increase in the average temperature of the earth’s surface Enhanced Greenhouse effect: greenhouse gases increase in the atmosphere -> excessive heat energy absorbed by the atmosphere
CAUSES Increase in agriculture activities: -Deforestation -Methane released when plant rot -Nitrogen-based fertilizers used thus releasing Nitrogen Oxide Increase in Motor Vehicles: -Nitrogen Oxide from exhaust pipes
Increase in the use of product containing Chlorofluorocarbon(CFCs) CONSEQUENCES(EFFECTS)
Climate Change and series of effects: Extreme weather events: Cooler regions became warmer -> boost agriculture productivity Multiplication of pests -> widespread diseases Frequent flooding and heat waves Endangering animals as temperature changes as they cannot adapt Rising Sea levels: Floods in low-land areas Contamination of flesh water Reduced food supplies as arable land submerged
RESPONSES
International co-operation/ Agreements: -Kyoto Protocol 2005(countries targets to reduce greenhouse gases emission; however not all countries signed)
Using Clean energy: Alternative energies that emit less carbon dioxide than fossil fuels -Clean energies: Hydro-electric, geothermal, solar, wind, nuclear, biogas, waves & tides & ocean thermal energy -Renewable= can be replaced -Impose taxes on industries which emit Greenhouse gases beyond acceptable levels -Incentives given to those successfully conserve energy
Individual efforts to conserve energy: -Use energy-efficient appliances and switch off when not in use - Use public transport -Walk or cycle -Spread message of the impacts of global warming and ways to curb it -Participate in community projects posted by queenie @ 6:55 PM 0 Comments
