Global Warming

8) Climate models using only natural forces are unable to explain the observed global warming since the mid-20th century, whereas they can do so when they include human influenced factors in addition to natural ones.

1) The Intergovernmental Panel on Climate Change (IPCC) states that it is highly likely ( more than 90% probable) that humans have caused global warming since the mid-twentieth century.

4) Different isotopes (elements with different numbers of protons) of carbon dioxide prove that the majority of CO2 in the atmosphere comes from fossil fuels.

Global Warming A Crisis

11) Creating and maintaining new energy plants will create jobs, boosting the economy.

9) $3 Trillion worth of assets at risk from rising waters due to melting ice caps.

5) The United Nations panel estimates that climate change is already reducing wheat yields by 2 percent each decade — compared with where they would be in the absence of climate change — and corn yields by 1 percent

7) Atmospheric concentrations of many gases—primarily carbon dioxide, methane, nitrous oxide and halocarbons- are now roughly 35 percent above preindustrial levels (before the Industrial Revolution)

12) The cost of renewable energy sources is decreasing with the advancement of technology.

The Facts

2) If the world’s demand for energy continues at its current rate oil will run out in 50 years, natural gas in 70 years, and coal in 250 years.

3) Observational records indicate that 11 of the past 12 years are the warmest since reliable records began, around 1850. 9


6) Beef and pork prices are at an all time high since 1987 due to the recent droughts, caused by global warming.

10) While America's energy consumption has increased, California's has not. Utility efficiency programs, appliance and building standards have saved California billions of dollars, millions of kilowatt hours and reduces the need for new power plants.

Applied VocabularyOpportunity Cost - The difference between renewable energy and coal would be the opportunity cost in global warming.Scarcity - The amount of fossil fuels is decreasing while demand is increasing.Consumption - Everyone uses energy, whether it’s gasoline or electricity directly, or the energy needed to make clothing and food.Production - The drilling for, extraction and refinement of oil, or the production of renewable energy sources.Interdependence - The US is dependent on the Middle East for most of its oil needs. Every person in some way needs this oil and the energy it produces.

Hurricane Sandy caused $19 billion in damages to New York alone.
