Global Warming speech to inform/persuade
I. Introduction:
A. "Global warming is the observed increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.
B. The average global air temperature near Earth's surface has risen about 0.74 °Celsius (1.3 °Fahrenheit) in the last century
C. Models of global warming referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100. The range of values reflects the use of future greenhouse gas emissions as well as uncertainties regarding climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if no further greenhouse gases are released after this date. This is because of the long average atmospheric lifetime of carbon dioxide (CO2).
