Climate change/Global Warming - Climate Change : long term change in temperature and precipitation patterns - Global Warming : the increase in the earth’s average surface temperature over time due to the greenhouse effect - Greenhouse effect : the increase in CO2 in the earth’s 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 earth’s 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, e.g. the natural solar cycle, at play

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
