Global Warming: The General Theory Lauren Gibbons, Martyn ‘S Gravemade, Arcan Chirathivat, Arielle Tenorio
Global Warming is defined as “the increase of the average temperature on Earth.” Every year the average temperature increases, causing natural disasters.
The sun is the Earth’s primary source of energy. The Greenhouse Effect : When energy trapped in the atmosphere warms the land, oceans, and air.
The gases that used to make life on Earth possible are now threatening our very existence. CARBON DIOXIDE CO 2 METHANE CH 4 NITROUS OXIDE NO 2
Greenhouse Gases: Gases that contribute to the Greenhouse Effect. Some Greenhouse Gases occur in nature- such as water vapor, methane, nitrous oxide, and carbon dioxide. Others are man made. Gas Main Source Overall contribution to increased global warming H 2 O Evaporation of oceans and lakes - CO 2 Combustion of fossil fuels and biomass 50% CH 4 Anaerobic decay of organic matter caused by intensive farming 18%% N 2 O Artificial fertilizers and combustion of biomass 6% O 3 Secondary pollutant in photochemical smogs 12% CFCs Refrigerants, repellants, foaming agents, solvents. 14%
Attributions to climate change include:
Arctic tundra's and wetlands.
The burning of fossil fuels such as oil, coal and natural gas is the main cause of climate change. Countries by Carbon Dioxide Emissions
As these gases and chemicals are released into the air, the concentration of the Ozone layer in the stratosphere decreases.
1. The spread of disease 2. Warm waters, hurricanes 3. Droughts and heat waves 4. Economic consequences Global Warming is negatively affecting the Earth and it’s occupants. Effects of Global Warming include:
5 . A major effect of Global Warming is the melting of polar ice caps . This is a “four-pronged” danger resulting in different situations. Raised sea levels Global ecosystem off balance Changing landscapes in the arctic circle endangers animals Global Warming increases with the melting of ice caps.
International School Bangkok can reduce their carbon footprint and their contribution to Global Warming by limiting the Week Without Walls (WWW) trips within Asia and the surrounding area. Finding the carbon footprint based on WWW air travel:
