Unformatted text preview: Climate change/Global Warming- Climate Change : long term change in temperature and precipitation patterns- Global Warming : the increase in the earths average surface temperature over time due to the greenhouse effect- Greenhouse effect : the increase in CO2 in the earths atmosphere prevents heat/energy from escaping back into space thereby causing temperature to rise o CO2 is most important greenhouse gas; others include methane/ozone water vapour o The earths atmosphere creates a natural greenhouse effect by preventing about one half of the outgoing radiation from reaching space( not related to human activity) o Human activity contributes to the greenhouse effect through the burning of fossil fuels, thereby causing temperatures to increase; this is an anthropogenic cause of global warming ( vs. the natural cause above) o The mean world air temperature has increased over the past 250 years(since the industrial revolution) but, is this due to the burning of fossil fuels or are other factors,...
