3. Increase in the average measured temperature of the Earth's surface air and oceans
4. GLOBAL WARMING is the increase in the average measured temperature of the Earth’s Near-surface air and oceans since the mid-twentieth century and its projected continuation
5. How Global Warming Works Greenhouse gases Fossil fuels (coal, oil, natural gas) Carbon Dioxide (CO 2 )
6.
7. It is the process by which absorption and emission of infrared radiation by atmospheric gases takes place which warm a planet’s lower atmosphere and surface.
14. Atmospheric Concentration of CO2 Present concentration: 385ppm by volume Expected concentration by the year 2100: 541-970ppm by volume (If the usage of fossil fuels continues like the present trend)
Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy or energy from renewable sources!
